A leg of an undescribed small diver was found in the Late Oligocene deposits at Enspel (Germany); it too may or may not belong to Colymboides. Of the crown genus Gavia, nearly ten prehistoric species have been named to date, and about as many undescribed ones await further study. The genus is known from the Early Miocene onwards, and the oldest members them are rather small (some are smaller than the red-throated loon). Throughout the late Neogene, the genus by and large follows Cope's Rule.Brodkorb (1953), 1963: pp. 223–225, Olson (1985: pp.

Specimens of Cherax holthuisi were collected in 1952, when M. Boeseman bought nine individuals from locals on the shores of Lake Aitinjo. They were deposited in the Rijksmuseum van Natuurlijke Historie (now part of Naturalis) as lots RMNH D 51503 and RMNH D 51504. The species remained undescribed, however, until Christian Lukhaup and Reinhard Pekny attempted to identify some exotic crayfish then on the market in Germany. Their specimens did not accord with any of the nine species described from New Guinea by Lipke Holthuis, but did match Boeseman's undescribed specimens.

It grows in shallow still or slowly-moving water deep An aquatic herbaceous plant, M. variifolium grows to about in length, its smooth stems around in diameter. Myriophyllum variifolium intergrades with the very similar M. simulans in western Victoria and South Australia. Molecular work indicated that M. variifolium and related species require further genetic investigation and that as yet undescribed cryptic species are likely; two lineages of M. variifolium were identified and both were paraphyletic to one lineage of M. simulans and an undescribed species.

All three currently described species come from the same strata near Foum Zguid in southern Morocco. Three as yet undescribed species are recorded from other locations.

Loudon described Ulmus campestris var. cucullata as having "leaves curiously curved, something like a hood". He thought the tree resembled an undescribed cultivar he called var. concavaefolia. This brief description was dismissed by Elwes and Henry (1913) as "insufficient" for distinguishing concave- and hooded-leaved elms.

It was first discovered by George Stewardson Brady in 1880, but remained undescribed until E. C. Fyan formally described it in 1916. The name "Bishopina mozarti", published by Bonaduce, Masoli & Pugliese in 1976, is a junior subjective synonym of N. timorensis, and commemorates Wolfgang Amadeus Mozart.

3 Zijlstra placed Agathaeromys within "clade C" in a clade with Oligoryzomys victus and an undescribed fossil species of Oligoryzomys from Aruba in his 2012 paper naming Dushimys.Zijlstra, 2012, fig. 3 As a whole, Oryzomyini includes over a hundred species in about thirty genera.Weksler, 2006, pp.

A number of undescribed species are known and many species show considerable variation across their ranges, which may indicate that more cryptic species exist.Gosliner, T.M., Behrens,D.

Hypsipyla robusta, the cedar tip moth, is a species of snout moth in the genus Hypsipyla. It was described by Moore in 1886. It is found from Africa (including Madagascar), throughout Asia (including Sri Lanka and India) to Australia. Several undescribed species or subspecies might be involved.

This species was described from Ile Marianne, Fouquets Reef, Mauritius. This species has been reported in error widely in the Indo-Pacific region but these reports should be referred to Glossodoris acosti or undescribed Glossodoris species. The only reliable recent records are from Réunion.Bidgrain, P., 2019.

25 cm (10-in) is its total length. Ground-feeder but roosts and nests on bushes or vines; seen in pairs in a flock. Birds with enlarged gonads recorded in April and May and a recent fledgling obtained on May 3. Nest and eggs are undescribed.

Inside the bodies of individuals of Aiteng ater, there were found to be white elongated endoparasites; these are as yet unstudied. However the "parasites" described for Aiteng ater might represent spicules instead, because the presence of spicules is confirmed for the undescribed species Aitengidae sp. from Japan.

The book describes and illustrates 34 species in detail. A further two "undescribed and incompletely diagnosed taxa" are included: Nepenthes species A (later described as N. rigidifolia)Akhriadi, P., Hernawati & R. Tamin 2004. A new species of Nepenthes (Nepenthaceae) from Sumatra. Reinwardtia 12(2): 141–144.

Seven novel diterpene molecules, microporenic acids A–G, were isolated from the cultures of an undescribed species of Microporus found in the Kakamega Forest of Kenya. These compounds have antimicrobial activity against several Gram-positive bacteria, and also inhibit the formation of biofilm by Staphylococcus aureus.

There is however a third, undescribed species occurring on the Ecuadorian coast and the status of the two junior synonyms of A. xanthaeolus, ica Osgood, 1944 and baroni J.A. Allen, 1897, is currently unresolved. Also, the subspecies A. galapagoensis bauri is sometimes considered a separate species.

Based on this study, the Ozark highland population should be recognized as the species T. eigenmanni. A population from Sloans Valley Cave, Pulaski County, Kentucky, differs in several ways from populations to the southwest in Tennessee along the Cumberland Plateau and might represent an undescribed species.

Undescribed specimen The pantodonts varied considerably in size: the small Archaeolambda, of which there is a complete skeleton from the Late Palaeocene of China, was probably arboreal, while the North American, ground sloth-like Barylambda was massive, slow-moving ("graviportal") and probably browsed on high vegetation.

This species was first formally described by Ferdinand von Mueller in 1855 and gave it the name Phebalium ovatifolium and the description published in Definitions of rare or hitherto undescribed Australian plants.In 1998, Paul G. Wilson changed the name to Nematolepis ovatifolia in the journal Nuytsia.

F. willsii may have been sighted once in western Madagascar at Ankarafantsika National Park, although this observation has not been verified as of 2007. Reports from Tsingy de Bemaraha Strict Nature Reserve are uncertain: they may be of F. willsii, F. petteri, or a similar, undescribed species.

The Choctaw bass (Micropterus sp. cf. punctulatus) is a provisional new species of black bass found in the upper panhandle of Florida.Tringali, M.D., Barthel, B., Seyoum, S., & Knight, J. (2015). The Choctaw Bass: an undescribed species of Micropterus in the Gulf Coastal Plain Rivers of Florida.

Unlike its closest relatives in the family, Cochliostema and Plowmanianthus,Hardy CR .2001. Systematics of Cochliostema, Geogenanthus, and an undescribed genus in the spiderwort family, Commelinaceae. PhD Dissertation, Cornell University, Itaca, NY, USA. its roots are both tuberous (although weakly so) and actually penetrate the soil.

Astatotilapia sp. 'shovelmouth' is a putative, formally undescribed species of freshwater fish in the family Cichlidae. It is endemic to Lake Victoria in Uganda. It was previously included in the IUCN Red List of Threatened Species as an endangered species, but omitted from more recent lists.

Nidirana adenopleura is a species of frog in the family Ranidae. It is found in Taiwan, south-eastern China, and in the Yaeyama Islands (Ryukyu Islands, Japan). Populations from Yaeyama Islands might represent a distinct, as yet undescribed species. The records from Vietnam and Thailand are uncertain.

In 2006, another new Apomys was described: Apomys camiguinensis (Camiguin forest mouse). Apomys also comprises several species which are yet undescribed, two of which are from Mindoro. Another species from Mindoro, from the predominantly Indonesian genus Maxomys, has yet to receive its scientific name.Musser & Carleton, 2005, pp.

There may also be some similar specimens in the area that are an as yet undescribed species. This bee feeds on many kinds of flowers. It is active year-round in some areas. It generally occupies pine-oak forest and other kinds of mountain forest habitat.

Qiongthela is a genus of spiders in the family Liphistiidae. , it contains 3 species, but there are 3 more undescribed species.Xu, X., Liu, F. X., Chen, J., Ono, H., Li, D. Q. & Kuntner, M. (2015). A genus-level taxonomic review of primitively segmented spiders (Mesothelae, Liphistiidae).

The bark is thin and flaky, finely shredding in longitudinal strips. Mock-oranges are used as food plants by the larvae of some Lepidoptera species including the engrailed (Ectropis crepuscularia). A noted pathogen of the sweet mock-orange (P. coronarius) is the undescribed proteobacterium called "Pseudomonas tomato" (pv. philadelphi).

The two species were found to live in association with larvae of Culex (Lophoceraomyia) jenseni, Uranotaenia (Pseudoficalbia) moultoni and an undescribed taxon, Tripteroides (Rachionotomyia) sp. No. 2. Concerning C. rajah, Tsukamoto noted that the "body surface of most larvae are covered in Vorticella-like protozoa".Tsukamoto 1989, p. 220.

The book describes and illustrates 31 species in detail. A further two "undescribed and incompletely diagnosed taxa" are included: Nepenthes sp. A (possibly a form of N. fusca) and Nepenthes sp. B (later described as N. hurrelliana).Cheek, M., M. Jebb, C.C. Lee, A. Lamb & A. Phillipps. 2003.

Agorius was first described by Tamerlan Thorell in 1877. No new species were described for about one hundred years, with seven new species found in the twenty-first century. Undescribed species have been found in Malaysia and Sabah. Several more species have been found but not yet described.

Leionema praetermissum was first formally described by Phillipa Alvarez and Marco Duretto in 2019 and the description was published in the journal Telopea. The specific epithet (praetermissum) is in reference to "this species having been identified as an undescribed taxon for at least three decades before being formally described".

Alpheus randalli was first described in 1981 from the Marquesas Islands in the Indian Ocean where it was found living at a depth of in association with a previously undescribed species of goby in the genus Amblyeleotris. This has now been given the name Randall's prawn goby (Amblyeleotris randalli).

The exact shape of the plates is hard to determine due to erosion. Paul considered the neck plates to be low, but the back plates as taller. Also the Aathal specimens are as yet undescribed. A complete description of the entire material is in preparation by Octávio Mateus.

2nd edition. There are 17 species of bivalves (Corbicula, Coelatura, Sphaerium, and Byssanodonta), including 6 endemic species/subspecies. It is likely that undescribed species of snails remain. Conversely, genetic studies indicate that some morphologically distinctive populations, traditionally regarded as separate species, may only be variants of single species.

In 1988, botanist Joachim Nerz became aware of it upon visiting the herbarium of Leiden University. The name N. aristolochioides was coined quite early on; it was already being used in 1994 to informally refer to this (at the time undescribed) taxon.Jebb, M. 1994. NEPENTHES revision for Flora Malesiana.

Labidochromis sp. "Mbamba", or the "Yellow Top Mbamba", is a maternal mouthbrooding cichlid fish from Lake Malawi, so far formally undescribed. They belong to the groups of fishes locally named mbuna which means rock dweller. They are one of the smaller mbuna species growing to 3-4inches as adults.

Several years before it was realized it represented an undescribed species (and not "just" black-headed uakaris), it was studied in the Pico da Neblina National Park in Brazil.Boubli, J. P. (1994). The black uakari monkey in the Pico da Neblina National Park. Neotropical Primates 2(3): 11-12.

2006 IUCN Red List of Threatened Species. Downloaded on 5 August 2007. The specific name honours David W. Greenfield and Teresa Arambula Greenfield, who when they collected type specimen though that it might belong to an undescribed species and so sent it to Bruce Baden Collette to be described.

This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000.

Based on DNA analysis, Gamble et al. (2012) placed this species in the genus Phyllopezus, along with three other described species and several undescribed species.Gamble T, Colli GR, Rodrigues MT, Werneck FP, Simons AM (2012). "Phylogeny and cryptic diversity in geckos (Phyllopezus; Phyllodactylidae; Gekkota) from South America's open biomes".

This species was described from the Izu Peninsula, Japan. It is widely distributed on the Pacific Ocean coasts of Japan and the Japan Sea coasts. A species from Indonesia has previously been identified as Doto bella but is now thought to be an undescribed species.Behrens, D. W. (2004).

All known members of this group are endemic to Brazil. The as yet undescribed species in this family expand the range to the coast of Ceará State and caves in the dry central part of Minas Gerais, where the cave- dwelling species could represent an example of relictual distribution.

"Omphalotropis sp. nov. 2" is the name used by the IUCN for an undescribed species of minute salt marsh snail with an operculum, a terrestrial gastropod mollusk, or micromollusk, in the family Assimineidae. This species is endemic to Madagascar. Its natural habitat is subtropical or tropical dry forests.

In 1994, Commonwealth Scientific and Industrial Research Organisation (CSIRO) chief researchers Peter Last and John Stevens provisionally gave the name Cephaloscyllium "sp. E" to an undescribed Australian swellshark with a variegated color pattern. Later investigation revealed that "sp. E" in fact constituted two species: the flagtail swellshark (C.

Other species groups have yet to be established. In early 2018, Bellati et al. moved the species Rhombophryne alluaudi to Plethodontohyla based on examination of the type material; specimens in phylogenetic analyses that had been referred to as R. alluaudi in fact belong to an undescribed species of Rhombophryne.

Nesting habits in New Guinea are undescribed. In northern Australia breeding takes place from November to January. The nest is a neat cup built of bark shreds and grass stems in the fork of a dead shrub near water. One whitish egg, spotted reddish-brown and grey, is laid.

The genus Geogenanthus is distinguished by a particular 6-celled stomatal complex and basal axillary inflorescences. An analysis of DNA sequences indicate Geogenanthus is closely related to the genus Plowmanianthus followed by Cochliostema.Hardy CR .2001. Systematics of Cochliostema, Geogenanthus, and an undescribed genus in the spiderwort family, Commelinaceae.

Skeleton of "Gadolosaurus" "Gadolosaurus" is an informal name given to an undescribed hadrosauroid from the Bayan Shireh Formation of Baishan Tsav, Mongolia.Tsogtbaatar, K., D. Weishampel, D. C. Evans, and M. Watabe. (In review). A New Hadrosauroid (Dinosauria: Ornithopoda) from the Late Cretaceous Baynshire Formation of the Gobi Desert (Mongolia).

The genus formerly had a disjunct distribution, with two species found in the Society Islands and the majority of the genus ranging from New Caledonia to Macquarie Island, but absent from the in between. Despite many fossil birds being found in the islands between these two areas being found none of these were of undescribed Cyanoramphus species. Like many other species of birds the Cyanoramphus parakeets have suffered from changes brought about by humans. The two species from the Society Islands, the black-fronted parakeet and the Society parakeet, have become extinct as have the subspecies from Lord Howe Island and Macquarie Island, as well as an undescribed form from Campbell Island.

This includes populations in far northern Madagascar that some have speculated represented an undescribed species, but a comparison of specimens did not support this, instead maintaining them as part of P. damii.Sparks, J. S. (2008). Phylogeny of the Cichlid Subfamily Etroplinae and Taxonomic Revision of the Malagasy Cichlid Genus Paretroplus (Teleostei: Cichlidae). Bulletin of the American Museum of Natural History Number 314 :1-151 In contrast, populations in the Mahanara River in northeastern Madagascar were formerly also included in P. damii, but these were described as a separate species, P. loisellei, in 2011, and populations in the Ankofia River basin in northwestern Madagascar (south of true P. damii) appear to represent a closely related undescribed species.

Llanocetidae is an extinct family of ancient toothed baleen whales from the Eocene. It was named by American paleontologist Edward Mitchell in 1989 after describing the Antarctic Llanocetus, but a 2018 study by paleontologists Ewan Fordyce and Felix Marx included the Peruvian Mystacodon and an undescribed New Zealand specimen OU GS10897.

The black-spotted whipray (H. astra) is a recently described, closely related species that was initially thought to be the same as H. toshi. Undescribed, related forms have also been documented from Indonesia and New Guinea. Other common names for this ray include coachwhip ray, Tosh's longtail ray, and Tosh's whipray.

This species is endemic to the South African coast and is found only from the Atlantic coast of the Cape Peninsula to the eastern side of False Bay in 5–15 m of water.Gosliner, T. M. 1987. Nudibranchs of Southern Africa As at November 2009, it remained undescribed by science.

The candelabra nudibranch (Eubranchus sp. 5 as designated by Zsilavecz, 2007), is a species of sea slug or nudibranch, a marine gastropod mollusc in the family Eubranchidae. It is an aeolid nudibranch, which is known to occur off the South African coast. As of August 2015, it remained undescribed by science.

Encarsia is a large genus of minute parasitic wasps of the family Aphelinidae. The genus is very diverse with currently about 400 described species and worldwide distribution.Noyes, J. S. 2003. Universal Chalcidoidea database The number of existing species is expected to be several times higher because many species are still undescribed.

More than 6,500 species of daddy longlegs described under 5 suborders. In Sri Lanka 21 species can be found under five families. The pettalid genus Pettalus Thorell, 1876 is now known to have three described and many undescribed species in Sri Lanka according to Hansen & Sørensen, 1904; Sharma & Giribet, 2006.

Heliotropium aff. wagneri is an undescribed plant in the family Boraginaceae. It resembles Heliotropium wagneri, but differs in fruits breaking up into four nutlets and flowers that are always yellow, never white. Endemic to Samhah in Yemen, its natural habitats are subtropical or tropical dry lowland grassland and rocky shores.

Rock wax-flower was formally described in 1855 by Victorian Government Botanist Ferdinand von Mueller who gave it the name Eriostemon trachyphyllus and published the description in his book, Definitions of rare or hithertoo undescribed Australian Plants. In 1998, Paul Wilson changed the name to Philotheca trachyphylla in the journal Nuytsia.

Regisaurus ("Rex's lizard", named after its discoverer Francis Rex Parrington) is an extinct genus of small carnivorous therocephalian. It is known from a single described species, the type species Regisaurus jacobi, from the Early Triassic Lystrosaurus Assemblage Zone of South Africa, although at least one undescribed species is also known.

In Hsiu-chuan Liao and Carl R. Galvez Rubino (eds.), Current Issues in Philippine Linguistics and Anthropology: Parangal kay Lawrence A. Reid, 306-336.

The IUCN Red List (2008) also mentions the island of Bioko (Equatorial Guinea) and eastern Democratic Republic of Congo, but remarks that the latter likely refers to a (then) undescribed species. Leptopelis fiziensis from eastern Democratic Republic of Congo and western Tanzania was originally included in this species as a subspecies.

Some portions of the gaster are deformed and the specimen appears to be crushed, but the overall morphology of this species justifies its placement within Myrmeciinae. An undescribed worker in the form genus Myrmeciites may possibly be a Y. bartletti ant, but this cannot be confirmed due to its poor preservation.

There is a fleshy, shiny green callus in the centre of the labellum and extending almost to its tip. Flowering occurs in November and December. A similar orchid found in Victoria, formerly included in this species, is now recognised as an undescribed species with the temporary name Prasophyllum sp. aff. validum.

In Panama, it is found on both the Caribbean and Pacific slope from . The preferred habitat is the canopy of wet forest and tall second growth, but it will feed lower at woodland edges and clearing. The neat cup nest is built on a tree branch. The eggs are undescribed.

South of the Cape Fear River basin there is an undescribed Apheloria species with yellow middorsal marks on most segments. A. tigana occurs in the Eastern United States, from southeastern North Carolina northward throughout the Blue Ridge Mountains.Hoffman, Richard L. 1999. Checklist of the millipeds of North and Middle America.

Lytopylus is a genus of parasitoid wasps in the family Braconidae. As members of the subfamily Agathidinae, they are koinobiont endoparasitoids of caterpillars. This genus is primarily found in the neotropics, but ranges from the northeastern United States to Argentina. There are 39 species of Lytopylus, and many more undescribed.

The fireworks nudibranch, Eubranchus sp. 4, as designated by Zsilavecz, 2007, is a species of sea slug or nudibranch, a marine gastropod mollusc in the family Eubranchidae. It is an aeolid nudibranch, which is known to occur off the South African coast. As at August 2010, it remained undescribed by science.

Either the latter genus is included here, or Huia is restricted to the type species (the Hole-in-the-head Frog, H. cavitympanum) and what might be its closest living relatives (e.g. an undescribed species from Sumatra), or some species of Huia - e.g. the Sumatran Torrent Frog (H. sumatrana) - are split off again.

Magnapinna sp. B is an undescribed species of bigfin squid known only from a single immature specimen collected in the northern Atlantic Ocean. It is characterised by its dark epidermal pigmentation, which is epithelial, as opposed to the chromatophoral pigmentation found in other Magnapinna species. The only known specimen of Magnapinna sp.

North America contains at least six genera. Australia contains three genera, two species of Corythangela and twenty-nine of Batrachedra, as well as a number of undescribed species and one species of Idioglossa. The Hawaiian Islands contain two genera, six of Batrachedrodes, and two of Chedra. Europe only has three species of Batrachedra.

Among them are the derived pachycephalosaurids Sphaerotholus, Stygimoloch, Dracorex, Pachycephalosaurus, and an undescribed specimen from North Dakota. Mammals are plentiful in the Hell Creek Formation. Groups represented include multituberculates, metatherians, and eutherians. The multituberculates represented include Paracimexomys, the cimolomyids Paressonodon, Meniscoessus, Essonodon, Cimolomys, Cimolodon, and Cimexomys; and the neoplagiaulacids Mesodma, and Neoplagiaulax.

In 2017, Chenanisaurus was placed in Abelisauridae in a basal position outside the Abelisaurinae and Carnotaurinae. Though it resembles carnotaurine abelisaurids in aspects of its jaw morphology, Chenanisaurus may belong to an as-yet undescribed group of abelisaurids unique to Africa. Only further research will determine the true relations of this species.

The beetles of the subfamily Pilipalpinae belong to the small family of fire- coloured beetles (Pyrochroidae). They are found only in the Southern Hemisphere, occurring in Australia, Chile, Madagascar and New Zealand. Most of the genera are small or even monotypic, but it is highly likely that a number of undescribed species exist.

The earliest fossils of Centrarchidae are from latest Eocene to early Oligocene deposits from Montana and South Dakota, belonging to several as yet undescribed species and the two extinct genera †Plioplarchus and †Boreocentrarchus. Both Plioplarchus and Boreocentrarchus are classified in the subfamily Centrarchinae, because these species possess more than three anal fin spines.

Giant isopods are not known from the East Atlantic or East Pacific. The greatest species richness (five species) is found off eastern Australia, but it is possible other regions that are not as well-sampled match this figure. In general, the distributions of giant isopods are imperfectly known, and undescribed species may exist.

Leptodactylodon stevarti is a species of frog in the family Arthroleptidae. It is known with certainty only from the area of its type locality, Monts de Cristal in northwestern Gabon. Only two specimens are known. However, there is an uncertain record from Equatorial Guinea that could represent this species or other, undescribed species.

Nothobranchius sp. nov. 'Lake Victoria' is a scientifically undescribed species of freshwater fish in the family Nothobranchiidae. It is endemic to Kenya, and inhabits intermittent freshwater marshes. It was listed as vulnerable in the IUCN Red List of Threatened Species in 2004, but is not included in recent versions of the list.

Psychroteuthis glacialis, the glacial squid, is the only known species in the monotypic genus Psychroteuthis, in the family Psychroteuthidae. While only one species has been confirmed, two undescribed species also probably exist. The species occurs in coastal waters near Antarctica and South America. It grows to a mantle length of 44 cm.

Several species have been described, with probably numerous undescribed species. The taxonomy of the genus is very confused, as these species show many local variations. Certain species, in isolated areas or with reduced populations, need to be observed as they face a distinct extinction possibility given the significant number collected by native people.

Dinosaur remains, such the Sauropod Tazoudasaurus and the Basal Ceratosaur Berberosaurus are known from the unit, along with several undescribed genera.Haddoumi, H., Charrière, A., & Mojon, P. O. (2010). Stratigraphie et sédimentologie des «Couches rouges» continentales du Jurassique-Crétacé du Haut Atlas central (Maroc): implications paléogéographiques et géodynamiques. Geobios, 43(4), 433-451.

Specimen CAMSMX.39256 is part of the collection of the Sedgwick Museum at Cambridge. Several specimens remain undescribed because they are in private collections. These include a 3.1 metres (ten feet) long skeleton found by David Sole in 2000, perhaps the most complete non-avian dinosaur exemplar ever discovered in the British Isles.

The lack of a roughly ridged and pitted cap differentiates it from the closely related Phallus impudicus. The fungus is named after Henry William Ravenel, a botanist who first discovered it in 1846, though it remained undescribed until 1873. It is considered to be an edible mushroom while in its egg form.

"Tonouchisaurus" (meaning "Tonouchi lizard") is the informal name given to an as yet undescribed genus of dinosaur from the Early Cretaceous Period. It was a theropod which lived in what is now Mongolia. The suggested "type species", "Tonouchisaurus mongoliensis", was coined by Barsbold in 1994. It was notably small: less than in length.

Phestilla is a genus of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the family Trinchesiidae. Its members are unusual in feeding on hard corals, unlike other members of the family Trinchesiidae which feed on hydroids. Adult Phestilla have no cnidosacs. This genus has been investigated using DNA phylogeny and undescribed species exist.

A third specimen was referred: IVPP V14322, a fragmentary skeleton. All three are in the collection of the IVPP in Beijing, China. However, Sinovenator fossils appear to be common in the Lujiatun Beds. In a 2006 survey of the Jehol Biota, Xu and Norell reported that hundreds of undescribed specimens are known.

Females give birth to 7-8 pups during the summer; newborns measure long. Sexual maturity is attained at under a length of for males, and for females. It has lived to 20 years old in captivity. A known parasite of this shark is an undescribed species of tapeworm in the genus Carpobothrium.

The type species, Diclonius pentagonus, was named by Edward Drinker Cope in 1876, based on a single tooth specimen (AMNH 3972). Other formally undescribed species include D. calamarius and D. perangulatus. Although Cope referred several other batches of teeth to the genus, under several species, the name is considered a nomen dubium.

Three of its species are found on the Marquesas Islands, three others in the neighboring Society and Austral Islands (and several undescribed ones are known from the latter group), and one from Phoenix Island between the Marquesas and Hawaii. Another undescribed species has been reported from Fiji. Finally, Proterhinus samoae is an originally Samoan species that feeds on Coconut Palms (Cocos nucifera) and has been widely dispersed to coconut plantations across Melanesia, Micronesia and Polynesia. It is not clear why there are no Aglycyderini in Australia, and though their distribution looks clearly relictual, this does not answer the question how these weevils should have arrived in the Macaronesian region: there is no record of them from the more than Direct distance.

Individual near Sydney, Australia, currently included in Pelagia noctiluca, but likely an undescribed species This jellyfish is best known from the North Atlantic region, ranging from 4th parallel north (just north of Equator) to the North Sea and Atlantic Canada, including the Mediterranean and Gulf of Mexico. There are reports from most other tropical or warm temperate seas around the world, including both the Pacific and Indian Oceans, with its apparent southern limit being 42nd parallel south. Some of the locations are California (rare), Hawaii (rare), and all around Australia (common). However, it is suspected that Pelagia noctiluca—as currently defined—is a species complex with records outside the North Atlantic region involving other closely related species that presently are unrecognized or undescribed.

Paulchoffatiidae is a family of extinct mammals that lived predominantly during the Upper Jurassic period, though a couple of genera are known from the earliest Cretaceous. Some undescribed fossils from the Middle Jurassic of England may represent earlier versions. Remains have been reported from Portugal, Spain and England. Paulchoffatiids were members of the order Multituberculata.

This species was first formally described in 1844 by Henry Barron Fielding and Charles Austin Gardner in Sertum Plantarum: or drawings and descriptions of rare and undescribed plants from the author's herbarium . The specific epithet (hamata) is from the Latin word hamus meaning "a hook" or "angle" referring to the curved ends of the leaves.

Pamelaria dolichotrachela, a new prolacertid reptile from the Middle Triassic of India. Journal of Asian Earth Sciences 21: 663–681. Other vertebrate remains include those of the lungfish Ceratodus, the actinopterygian fish Saurichthys, the temnospondyl Parotosuchus, the dicynodonts Rechnisaurus and Wadiasaurus, the rhynchosaur Mesodapedon, and a large undescribed erythrosuchid. Restoration of the contemporary dicynodont Wadiasaurus.

Haines, T., James, J. Time of the Titans . ABC Online. The original description of the spines noted that the specimens in the Howe Quarry near Shell, Wyoming were associated with skeletal remains of an undescribed diplodocids "resembling Diplodocus and Barosaurus." Specimens from this quarry have since been referred to Kaatedocus siberi and Barosaurus sp.

Pisolithus hypogaeus is a fungus in the genus Pisolithus, occurring in coastal south-western Australia in association with eucalypt ectomycorrhizal hosts on sandy soils. DNA samples show that Pisolithus hypogaeus is a relative of other brown- and echinulate-spored Pisolithus species, and is most closely related to two undescribed epigeous Pisolithus species from Australia.

The Latin word affinis can be translated as "closely related to", or "akin to". An author who inserts n.sp., or sp. nov., aff before a species name thereby states the opinion that the specimen is a new, previously undescribed species, but that there may not (yet) be enough information to complete a formal description.

In retirement he focused on Mon–Khmer languages; as a guest researcher at Mahidol University he did extensive fieldwork in Thailand and Laos, particularly on the Mlabri tribal language, an endangered and previously undescribed dialect of a Khmuic language. His 1995 book described Mlabri phonology, morphology and syntax whilst supplying a lexicon with illustrative examples.

The postcrania of the type specimen remains undescribed, still in its plaster jackets. Specimen CMNFV 8399, holotype of E. edmontoni, now thought to be a young E. regalis. Two more species that would come to be included with Edmontosaurus were named from Canadian remains in the 1920s, but both would initially be assigned to Thespesius.

L. invasa was discovered in 2000 when river red gums in the Middle East and Mediterranean began developing disfiguring galls. The damage became severe enough to cause crop losses in tree plantations. Galls were collected and a previously undescribed species of chalcid wasp emerged. In 2004 it was described to science as Leptocybe invasa.

The internalization of vegetal cells prior to gastrulation was first observed in the 1930s by Abraham Mandel Schechtman through the use of vital dye labeling experiments in Triturus torosus embryos.Schechtman, A.M., 1934. Unipolar ingression in Triturus torosus: A hitherto undescribed movement in the pregastrular stages of a urodele. Univ. Calif. Pub. Zool. 39, 303–310.

20 possibly undescribed species of cichlids are known from the lake. The introduced species are three cichlids, the longfin tilapia (Oreochromis macrochir), blue-spotted tilapia (O. leucostictus) and redbreast tilapia (Coptodon rendalli), and a clupeid, the Lake Tanganyika sardine (Limnothrissa miodon). The exploitable stock of the Lake Tanganyika sardine was estimated at per year.

Ayscough, Samuel (1782) A Catalogue of the Manuscripts Preserved in the British Museum Hitherto Undescribed: Consisting of Five Thousand Volumes. British Museum. After his death, Ray and Petiver were in communication with Bulkley. It was through Bulkley that Ray's Synopsis Methodica Avium (1713) included a list of birds and some illustrations by natives from Madras.

Masters, M.T. 1872. The cultivated species of Nepenthes. The Gardeners' Chronicle and Agricultural Gazette 1872(16): 540–542. A number of Hooker's names appeared there for the first time, including the two varieties of N. rafflesiana and one of N. albomarginata; the as yet undescribed N. khasiana was included under the spelling N. khasyana.

One right ilium of a Marshosaurus bicentesimus is deformed by "an undescribed pathology" which probably originated as a consequence of injury. Another specimen has a pathological rib. In a 2001 study conducted by Bruce Rothschild and other paleontologists, five foot bones referred to Marshosaurus were examined for signs of stress fracture, but none were found.

Macrobrachium agwi is a species of freshwater shrimp, first described in 2008, endemic to the Himalaya. It was discovered when a shipment of ornamental prawns, destined for the aquarium trade, was shipped from Cooch Behar, West Bengal, India to Europe. Examination of the shipment showed that one type of shrimp was a new, undescribed species.

Wing et al., 1968, p. 128; Steadman et al., 1984a A more detailed study on the remains from Burma Quarry, an Amerindian site which is about 4500 to 2500 years old, reported the presence of a large rice rat, known as "Undescribed species B", which also occurred on nearby Barbuda, Montserrat, Guadeloupe, and Marie Galante.

Draft genome sequences of two strains most likely representing two undescribed Limnohabitans species were published.Zeng, Y., Kasalický, V., Šimek, K., and M. Koblížek (2012) Genome sequences of two freshwater betaproteobacterial isolates, Limnohabitans species strains Rim28 and Rim47, indicate their capabilities as both photoautotrophs and ammonia oxidizers. J. Bac. 194:6302-6303. (doi: 10.1128/JB.

Plant Diversity and Evolution (formerly Botanische Jahrbucher) 128(1-2):23-54. . These studies have shown that biogeography is strongly correlated with relationships in Araliaceae. In 2010, the genus Polyscias was expanded from about 100 species to 159. The number of species in Polyscias will be around 250 when the undescribed species are published.

The Three Kings have extremely high levels of endemism, even compared to other isolated islands. About 35% of its beetle species are found nowhere else, and there are six endemic genera: Gourlayia (Carabidae), Heterodoxa and Pseudopisalia (both Staphylinidae), Partystona and Zomedes (both Tenebrionidae) and Tribasileus (Anthribidae). There are probably another seven undescribed endemic genera.

Arcovomer is a genus of frogs in the family Microhylidae. It is monotypic, being represented by the single species Arcovomer passarellii, commonly known as Passarelli's frog. It is endemic to south-eastern Brazil and found in Espírito Santo, Rio de Janeiro, and São Paulo states. Frogs from Espírito Santo may represent another, undescribed species.

The crazed nudibranch, Corambe sp., as designated by Gosliner, 1987, is a species of sea slug, a dorid nudibranch, a marine gastropod mollusc in the superfamily Onchidoridoidea. It is also known as the moss animal nudibranch because its usual prey is a bryozoan, or moss animal. As at November 2009, it remained undescribed by science.

In 1896, Hugh FultonFulton H. (1896). "A list of the species of Amphidromus, Albers, with critical notes and descriptions of some hitherto undescribed species and varieties". Annals and Magazine of Natural History (6)17: 66–94, plates 5–7. organized 142 specific and varietal names into eighteen species groups containing a total of 64 species.

Vintana, a large sized gondwanathere mammal The mammal fauna known from the Maevarano Formation is dominated by gondwanatheres, a lineage of herbivorous multituberculates. These include Lavanify miolaka, Vintana sertichi, Adalatherium hui and at least one undescribed taxa.Krause et al, 2014 Some taxa are particularly large sized herbivores, exemplifying the diversity of Mesozoic mammals.Krause et al.

The spider was described along with a previously undescribed species of fly, which appeared to have a kleptoparasitic relationship with it. The flies often feed on the spider's catches before the spider wraps them. Occasionally, spiders have been observed to chase away the flies when they land on something that the spider is eating.

Philodendron is a large genus of flowering plants in the family Araceae. , the World Checklist of Selected Plant Families accepted 489 species; other sources accept different numbers. Regardless of number of species, the genus is the second-largest member of the family Araceae. Taxonomically, the genus Philodendron is still poorly known, with many undescribed species.

His description of the red berries appears to confuse this tree with another rare, local and hitherto undescribed species, T. floridana. Torrey realised that Croom was quite mistaken, and that the specimens represented a species new to science. Croom and his entire family drowned in a shipwreck off the coast of North Carolina in 1837.

An undescribed tyrannosaur stored in the Museum of the Rockies has a fractured humerus that healed in such a way leaving it shorter and with a more pronounced curve than a healthy specimen. Three of its ribs also seem to have been fractured and healed. The specimen TMP97.12.229 had a fractured and healed gastralium.

Microphallus sp. is a widespread and locally common undescribed parasite in New Zealand lakes and streams. Multilocus allozyme genotype data show that Microphallus is a single outbred species with high levels of gene flow among South Island populations. The parasite exclusively uses Potamopyrgus antipodarum as the intermediate host, and the final hosts are waterfowl.

"Dachongosaurus" is the informal name given to an undescribed genus of sauropod dinosaur from the Early Jurassic of China. It is known from fossils including at least a partial articulated skeleton from the Dark Red Beds of the Lower Lufeng Series (Sinemurian stage) in Yunnan.Zhao, 1985. The reptilian fauna of the Jurassic in China.

The sooty grunter is endemic to northern Australia from the upper Burdekin River in Queensland to the Daly River in the Northern Territory It has been reported from southern New Guinea. although this refers to an undescribed species but it is absent from the Cape York Peninsula. It has been widely translocated within Australia.

The brown goshawk is widespread through Australia, Wallacea, New Guinea, New Caledonia, Vanuatu and Fiji. In Australia, it is found mainly in eucalypt forests and woodlands, as well as farmland and urban areas. In the Pacific, it mainly inhabits rainforest. It was also found on Norfolk Island to about 1790, and this may be another undescribed subspecies.

Stropharia aeruginosa, commonly known as the verdigris agaric, is a medium- sized green, slimy woodland mushroom, found on lawns, mulch and woodland from spring to autumn. The edibility of this mushroom is controversial - some sources claim that it is edible, while others claim it to be poisonous, although effects are little known and its toxic constituents undescribed.

Parallocorynus has to date only been collected from the cycad genus Dioon. Similarly Rhopalotria is associated with various species of Zamia cycads, though one of the as yet undescribed species was collected from Dioon spinulosum. It seems that the species of Rhopalotria are monophagous - like R. slossoni on Coontie (Z. pumila) or R. mollis on Cardboard Cycad (Z.

The Braconidae are a family of parasitoid wasps. After the closely related Ichneumonidae, braconids make up the second-largest family in the order Hymenoptera, with about 17,000 recognized species and many thousands more undescribed.Jones, O. R., et al. (2009). Using taxonomic revision data to estimate the geographic and taxonomic distribution of undescribed species richness in the Braconidae (Hymenoptera: Ichneumonoidea).

Four species of Acanthoctesia in the genus Acanthopteroctetes are very localised in Western North America (Davis, 1978). Another genus, Catapterix represented by a single species comes from single sites at "Mount Karadag" and "Krasnolesie" in the Crimean Peninsula of the Ukraine (Zagulajev and Sinev, 1988). A third taxon, undescribed, is known from the Andes in Peru (Kristensen, 1999: 54).

The distribution of the Aglycyderini is very puzzling. Aglycyderes contains one species in the Canary Islands and one in nearby Morocco. Aralius has one named species in New Zealand and one named and two known but undescribed species in New Caledonia. Proterhinus with its 167 or so known species is found mainly in the Hawaiian Islands.

In 2005, it was found that the otherwise relatively well known S. speluncae actually consisted of two species, of which the southern was described as a new species, S. pachecoi, while the northern retained S. speluncae. It was further suggested that S. speluncae included yet another undescribed species, but more work was needed on that matter.

Phylogenetic evidence suggests that undescribed taxa from the genus Scytalopus remain in eastern Brazil.Mata, Helena; Fontana, Carla S.; Maurício, Giovanni N.; Bornschein, Marcos R.; Ferreira de Vasconcelos, Marcelo & Bonatto, Sandro L. (2009). Molecular phylogeny and biogeography of the eastern Tapaculos (Aves: Rhinocryptidae: Scytalopus, Eleoscytalopus): Cryptic diversification in Brazilian Atlantic Forest. Molecular Phylogenetics and Evolution 53(2): 450-462.

Optical microscopy image of the undescribed species of Spinoloricus from Loricifera stained with rose bengal. Despite its complicated photochemistry involving several species, rose bengal is also used in synthetic chemistry to generate singlet oxygen from triplet oxygen. The singlet oxygen can then undergo a variety of useful reactions, particularly [2 + 2] cycloadditions with alkenes and similar systems.

Eois is a genus of moths in the family Geometridae. The genus contains about 250 validly described species, most from the Neotropical region. Many species are still undescribed and the total number of species is estimated to be over a 1,000 in the Neotropical region alone. The genus was first described by Jacob Hübner in 1818.

Paleoophiocordyceps coccophagus is an extinct parasitic fungus in the family Ophiocordycipitaceae from Cretaceous-aged Burmese amber. P. coccophagus' morphology is very similar to the species of Ophiocordyceps. The only known specimen consists of two whip-like fruiting bodies emerging from the head of a male scale insect of an undescribed species very similar to the extinct species Albicoccus dimai.

They may be distinguished from H. anicata by the swollen distal half of the uncus (as opposed to gently tapered) and the absence of a moderately large, upcurved spine at the end of the costa. Females may be distinguished from females of H. unnia by their longer, more complex signa. The female of H. anicata is undescribed.

Robert Brown's taxonomic arrangement of Banksia was published in his book of 1810, Prodromus Florae Novae Hollandiae et Insulae Van Diemen, and expanded in the supplement to that publication, Supplementum Primum Prodromi Florae Novae Hollandiae, in 1830. It was the first survey of Banksia species to be published, and included descriptions of a number of previously undescribed species.

The male has black legs, a yellow iris and a brown and greenish down-curved bill. The female is similar but has a brighter hindneck colour, less white on the chin, a red iris, a cream and reddish bill and blue-grey legs. Immature and juvenile plumages are undescribed. Visual confusion with sympatric rails is unlikely.

There are approximately 100 described species and certainly many more as yet undescribed. The known species are grouped in two orders. The filospermoids are very long and are characterized by an elongate rostrum. The bursovaginoids have paired sensory organs and are characterized by the presence of a penis and a sperm-storage organ called a bursa.

Fossils found near Warsaw by paleontologist, Friedrich von Huene in 1941 were misidentified as being the teeth and parts of the jaw of a new species of dinosaur, which he named Succinodon putzeri. It was later determined that these were in fact the fossil remains of a marine boring bivalve, a previously undescribed species of Kuphus.

Three undescribed species also belong in the genus. Species of Porpolomopsis have also formerly been placed in the genus Humidicutis, to which they are closely related but differ in having narrowly attached or free gills and the shape of the hyphae in their cap. Species of Porpolomopsis are found in Europe, North America, Asia, Australia and New Zealand.

Typhlocybinae is a subfamily of insects in the leafhopper family, Cicadellidae. This is currently the second largest leafhopper subfamily based on the number of described species, but researchers believe there are so many taxa yet undescribed that it is probably the largest subfamily.Dietrich, C. H. (2013). South American leafhoppers of the tribe Typhlocybini (Hemiptera: Cicadellidae: Typhlocybinae).

Pelargonium sp. Striatellum, commonly known as Omeo stork's-bill, is an undescribed species of Pelargonium that is endemic to Australia. It is listed as "endangered" under the Environment Protection and Biodiversity Conservation Act, "endangered" in New South Wales and "vulnerable" in Victoria. It exists in five known locations; four in New South Wales and another in Victoria.

The postcrania of the type specimen remains undescribed, still in its plaster jackets. Skull NHM R8927 at the Natural History Museum Two more species that would come to be included with Edmontosaurus regalis were named from Canadian remains in the 1920s, but both would initially be assigned to the genus Thespesius. Gilmore named the first, Thespesius edmontoni, in 1924.

In 2000, three previously undescribed species of shrub were collected on the station, and subsequently published as Banksia rosserae, Grevillea squiresiae and Grevillea kirkalocka. The last of these is named after Kirkalocka. Due to proximity to mining areas, the station area was reviewed for its geological potential in 2000. Badimaya elder Ollie George grew up on the station.

They are often called slug moths because their caterpillars bear a distinct resemblance to slugs. They are also called cup moths because of the shape of their cocoons. The larvae are often liberally covered in protective stinging hairs, and are mostly tropical, but occur worldwide, with about 1000 described species and probably many more as yet undescribed species.

Leiobunum spec. from the Netherlands Leiobunum vittatum Leiobunum aldrichi An as yet undescribed species of Leiobunum was first found in the Netherlands in October 2004, although reports date back to at least 2002. Since then it has been identified from Germany, Switzerland and Austria. It is distinct from all known central European species and was probably introduced.

40: 1-168 Holtz et al. (2004) mentioned much more complete specimens, but they are undescribed. There have been doubts about the validity of Kaijiangosaurus. It has been suggested that it should be regarded as a junior synonym of Gasosaurus, which was found in the same strata as Kaijiangosaurus, the Lower Shaximiao Formation, or of Xuanhanosaurus.

Nepenthes tenuis (; ) is a tropical pitcher plant endemic to Sumatra. The species was first collected in 1957, from a remote mountain in the western part of the island. It remained undescribed until 1994, and was only rediscovered in the wild in 2002. Prior to this, N. tenuis was known solely from a single photograph and dried herbarium specimen.

These two species are the only described albertosaurines; other undescribed species may exist. Thomas Holtz found Appalachiosaurus to be an albertosaurine in 2004, but his more recent unpublished work locates it just outside Tyrannosauridae, in agreement with other authors. The other major subfamily of tyrannosaurids is the Tyrannosaurinae, including genera such as Daspletosaurus, Tarbosaurus and Tyrannosaurus.

The large pansy orchid is common in near coastal shrubland and woodland between Lancelin and Mandurah in the Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain biogeographic regions. At the northern end of its distribution, this species hybridises with the as yet undescribed Arrowsmith pansy orchid (Diuris sp. 'Eneabba') and in the south with D. corymbosa.

Retrieved 24 May 2014. This may be an underestimate of the true diversity, as parts of the basin are poorly known. For example, surveys of the upper Mazaruni River found 36–39 species (variation in number due to taxonomy), of which 13–25% still were undescribed in 2013. At least 24 fish species are resticted to Mazaruni River alone.

The final common name, Almora loach, refers to Almora in Uttarakhand, India. Specimens labelled as B. almorhae are commonly found in the aquarium trade, but most (if not all) of these appear to be the closely related B. lohachata, two possibly undescribed species popularly referred to as B. sp. "Kosi" and B. sp. "Teesta", or hybrids.

The exact spring and associated waters inhabited by the Villa Lopez pupfish were also the home of a now-extinct, undescribed species of Cambarellus crayfish. The specific name honours the daughter of María de Lourdes Lozano-Vilano and niece of Salvador Contreras-Balderas, Cecilia Contreras Lozano, who assisted on the trip on which the type was collected.

The spring pond inhabited by the Charco Azul pupfish was also the home of a now-extinct, undescribed species of Cambarellus crayfish. The specific name inmemoriam means "in memory" and signifies the extinction of the species due to its native spring being dried out by groundwater extraction soon after the discovery of this fish in 1983.

The park harbors several endemic insects including the Great Sand Dunes tiger beetle, a circus beetle (Eleodes hirtipennis), Werner's (Amblyderus werneri) and Triplehorn's (Amblyderus triplehorni) ant-like flower beetle, as well as undescribed species of clown beetle, noctuid moth, and robber fly. More than a thousand different kinds of arthropods have been found at the Great Sand Dunes.

The giant Laotian harvestman is the unofficial name for an as-yet undescribed species of opiliones belonging to the family Sclerosomatidae. The species was discovered in April 2012 near a cave in the southern province of Khammouan, by Dr. Peter Jäger of the Senckenberg Research Institute in Frankfurt, Germany, whilst shooting a television documentary about the wildlife of Laos.

Murray (1992) concluded that Hulitherium is most closely related to the New Guinean Maokopia, and that these two together are most closely related to Kolopsis rotundus also from new Guinea. Black and Mackness (1999) suggested that the Hulitherium clade is more closely related to the clade comprising Zygomaturus plus another undescribed genus from Australia, than it is to Kolopsis.

Daphnia pulex (Cladocera: Daphniidae) Cladocera is an order of small crustaceans commonly called water fleas. Around 620 species have been recognised so far, with many more undescribed. They are ubiquitous in inland aquatic habitats, but rare in the oceans. Most are long, with a down-turned head, and a carapace covering the apparently unsegmented thorax and abdomen.

A large phylogenetic analysis performed by Fischer (2013) in his unpublished thesis found Sisteronia to be a member of Platypterygiinae. Even though variants of this analysis have been formally published, the scorings of Sisteronia are based mainly on undescribed referred material currently held in a private collection, and therefore the publication of this cladogram is pending.

Mason Hale was an expert of the Parmeliaceae, a large family of foliose lichens. Hale wrote numerous monographs and articles describing new genera and species. Before Hale, Parmelia was a large genus containing a wide range of morphological traits. Hale became interested in the Parmeliaceae because there was a number of undescribed species in the southeastern United States.

Haeterius blanchardi is a species of clown beetle in the family Histeridae. These beetles are native to the United States, and have been found in Wisconsin, Massachusetts, and New Jersey. Haeterius blanchardi is a Myrmecophily species, living in colonies of the ant species Formica pallidefulva. The larvae remain undescribed, but likely develop in the nests of the host ants.

Nguyen et al. suggested that the Quảng Bình and Phou Hin Poun populations may be distinct and genetically isolated from each other. Nicolas et al. found 8 major geographical clades and 8 to 16 evolutionary significant units among Laotian rock rat populations in Laos, and suggested that Laonastes may in fact consist of various undescribed cryptic species.

The genus Axarus is widely distributed with records from the Holarctic, the Neotropics and Australasia . There are currently 5 described nearctic species . Erected as a subgenus (Anceus) of Xenochironomus , Axarus was subsequently renamed and elevated to generic status . The Connecticut River in the eastern United States harbors locally dense populations of two Axarus species, both currently undescribed.

Phylogenetic evidence suggests that undescribed taxa from the genus Scytalopus remain in eastern Brazil.Mata, Helena; Fontana, Carla S.; Maurício, Giovanni N.; Bornschein, Marcos R.; Ferreira de Vasconcelos, Marcelo & Bonatto, Sandro L. (2009). Molecular phylogeny and biogeography of the eastern Tapaculos (Aves: Rhinocryptidae: Scytalopus, Eleoscytalopus): Cryptic diversification in Brazilian Atlantic Forest. Molecular Phylogenetics and Evolution 53(2): 450-462.

In 1994, Commonwealth Scientific and Industrial Research Organisation (CSIRO) chief researchers Peter Last and John Stevens recognized five undescribed swellsharks in Australian waters. Later investigation revealed that the forms provisionally named Cephaloscyllium "sp. B" and "sp. C" may represent clinal variants of a single species, which was described by Peter Last and William White in a 2008 CSIRO publication.

The eggs are undescribed, but members of this family typically lay two white eggs. The adult ruddy treerunner is 16 cm long, weighs 18 g and looks like a small, short-billed woodcreeper, but has soft, rather than rigid, tail spines. It has bright rufous upperparts and a white supercilium. It has a white throat and otherwise tawny underparts.

Cyprinodon macularius was first described by Spencer Baird and Charles Girard in 1853. Originally, it was considered to be made up of three subspecies: the nominal desert pupfish (Cyprinodon macularius macularius), the Quitobaquito pupfish (Cyprinodon macularius eremus) and the undescribed Monkey Spring pupfish (Cyprinodon sp.).United States fish and Wildlife Service (1993). Desert Pupfish (Cyprinodon macularius) Recovery Plan. (Unpublished).

Size comparison In 2008, the Korea-Mongolia International Dinosaur Expedition at the Altan Uul III site in the Gobi Desert excavated a dense concentration of theropod skeletons. Some of these were of Gobiraptor as well as a yet undescribed oviraptorid but three were of Alvarezsauridae. One specimen, MPC-D 100/206, was considered cf. Mononykus sp.

The long green wrasse, Pseudojuloides elongatus, is a species of wrasse native to coastal waters from Australia to New Zealand and Norfolk Island (records from the Izu Islands, Japan are considered an undescribed species). This species occurs to depths around in weedy areas on reefs. It can reach in standard length. This species is also found the aquarium trade.

A/C and Apomys sp. B. The local population of A. musculus, the only other Apomys known on the island, may also represent a separate species.Musser & Carleton, 2005, p. 1283 Several other species occur exclusively on Mindoro (in addition to the undescribed Maxomys species mentioned earlier), including Oliver's warty pig, the tamaraw and the megabat Styloctenium mindorensis.

The Round Island skink also gives a SENI value of .06. The Round Island skink is a species capable of caudal autotomy. This skink is often seen darting in the underbrush or between rocks. An undescribed extinct Leiolopisma from Réunion was closely related, whereas the Round Island skink is a more distantly related surviving species from Mauritius.

"Lancanjiangosaurus" (alternative spelling "Lanchanjiangosaurus"; meaning "Lancangjiang lizard", named after the Lancangjiang River of China) is the informal name given to an as yet undescribed genus of sauropod dinosaur from the Middle Jurassic. The "type species", "L. cachuensis", was coined by Zhou in 1985, but remains a nomen nudum. It is known from the Dapuka Group of Tibet.

Sharfia mirabilis is an extinct species of anglerfish in the family Lophiidae. It was discovered in 2011 during a review of fossil material at the Muséum national d'histoire naturelle in Paris. The fossil material was collected from the Monte Bolca Lagerstätte, one of the earliest known Eocene fossil sites. The undescribed genus was originally identified as Lophius brachysomus.

The waters it inhabits have zero to moderate flow and high clarity. The species can tolerate water with a pH around 5.5, a hardness less than 10 ppm, a temperature between 18 and 20°C, and levels of dissolved oxygen between 5.8 and 6.0 ppm. C. parvus is sympatric with E. yigara, Caridina zebra, and an undescribed Macrobrachium sp.

In paleontology, it is typically used when the identification is not confirmed. For example, "Corvus cf. nasicus" was used to indicate "a fossil bird similar to the Cuban crow but not certainly identified as this species". In molecular systematics papers, "cf." may be used to indicate one or more undescribed species assumed related to a described species.

The range of S. scutata includes the Mediterranean Sea and the western Atlantic Ocean as far north as the English Channel; the type locality is the Gulf of İzmir on Turkey's west coast. It prefers depths between . Records of individuals at greater depths are likely to refer to other, as yet undescribed species. [S. scutata: p.

The importance of such programs for fish conservation is that some of the species they focus on have little to no commercial value in the fish trade and emphasize those that are overlooked by many conservation programs. For example, fish of the family Goodeidae, are largely threatened, with endangered and some species already extinct in the wild, such as the Golden skiffia (Skiffia francesae)', are largely kept alive due to dedicated aquarium hobbyist associated with CARES. They can also be a valuable resource, since aquarium hobbyists often pay more attention to the conservation status of particular fish groups and possess more detailed descriptions of undescribed species than the scientific community. Out of the nearly 600 species of freshwater fish in the CARES priority list, over 80 species are currently undescribed by the IUCN.

Maoripamborus fairburni is a species of beetles in the family Carabidae, the only described species in the genus, though there are some reports of an additional undescribed species.NZOR (Web Service Demonstrator) The genus is endemic to northern North Island in New Zealand, and is most closely related to the Australian genus Pamborus.Larochelle, A.; Larivière, M.-C. 2001: Carabidae (Insecta: Coleoptera): catalogue.

It has a rhizome, which is undescribed. It has basal leaves, that can be described as evergreen (staying on the plant even during very cold winters). They are between 6 mm to 2 cm wide.Thomas Gaskell Tutin (editor) They can grow as tall as the flowering stem at blooming time, but they then can grow taller after blooming period is over.

Head brownish. Feeds in July and after hibernation on various grasses, among which Poa annua, Festuca ovina, Aira praecox, and A. caespitosa have been specified as eaten by caterpillars in confinement. A distinct preference, however, has been shown for mat grass (Nardus strictus), and it has been suggested that this may be the natural food. The full-grown caterpillar appears to be undescribed.

An analysis of cranial head measurements, as well as mitochondrial cytochrome b phylogeny shows C. ansorgei to be distinct from other members of the genus Cricetomys. C. ansorgei may have a largely-undescribed sister species that resides west of the Congo River. Previously, many animals described as Cricetomys gambianus may have instead been C. ansorgei based on this new characterization.

S. stilesi and S. rodriguezi from Colombia). The Brazilian taxa are similarly complex with several recently described species and considerable confusion surrounding the use of the scientific name Scytalopus speluncae. Additionally, still undescribed species are known to exist (e.g. the "Apurimac tapaculo" and "Millpo tapaculo"; both from Peru), while some species as currently defined actually may include several species (e.g.

The common name, Desmarest's hutia, is for Anselme Gaëtan Desmarest who described the species in 1822 with the synonym fourniere. An extinct undescribed species of Capromys from the Cayman Islands is known from abundant subfossil material. It is close to the common Cuban Capromys pilorides, but smaller. The earliest radiocarbon records are latest Pleistocene and the latest are from around 1600 CE.

However, after the description failed to be presented, Cockerell wrote the American Museum Novitates article rather than let the fossil continue to go undescribed. At the time of description, the Florissant Formation was considered to be Miocene in age. Further refinement of the formation's dating has resulted in an age of 34 million years. This places the formation in the Eocene Priabonian stage.

At this time, he co-authored species including Rozites armeniacovelatus (now Cortinarius armeniacovelatus). For this work at Monash University, he received an Honorary Master of Science degree in 1988. Fuhrer was a Senior Technical Officer, Departments of Ecology and Evolutionary Biology, at Monash University for the years 1972 to 1996. Fuhrer has discovered several previously undescribed fungal species and described many liverworts.

Palaeontologica Sinica 162 New Series C 23. Science Press Peking: pp. 1-136 In 1999 Li Kui mentioned a second species: Zizhongosaurus huangshibanensisK. Li, Y. Zhang, K. Cai, 1999, The Characteristics of the Composition of the Trace Elements in Jurassic Dinosaur Bones and Red Beds in Sichuan Basin, Geological Publishing House, Beijing but this has remained an undescribed nomen nudum.

The animal life of Red Hill was also quite diverse. Early arachnids (Gigantocharinus), millipedes (Orsadesmus), and undescribed scorpions were among the few fully terrestrial members of the Red Hill fauna. The waterways were inhabited by a large variety of fish. Benthic placoderms such as the rare Phyllolepis, the common Groenlandaspis, and the abundant Turriaspis were a large part of the fish assemblage.

This terminology is still used by some researchers. The species of Pneumocystis originally seen by Chagas have not yet been named as distinct species. Many other undescribed species presumably exist and those that have been detected in many mammals are only known from molecular sample detection from lung tissue or fluids, rather than by direct physical observation. Currently, they are cryptic taxa.

Seven species of Halgerda were described in the years 1880-1905, two species in 1932-1949, four species from 1975-1982, then 22 species in the years 1993-2001. In 2018 another six new species were described from Mozambique, highlighting the number of undescribed species on the African coast of the Indian Ocean.Tibiriçá, Y.; Pola, M.; Cervera, J. L. (2018).

Boronia algida was first formally described in 1855 by Ferdinand von Mueller who described it as "a charming bush" and published the description in his book Definitions of rare or hitherto undescribed Australian plants. The specific epithet (algida) is a Latin word meaning "cold", von Mueller having noted that this plant grows "on the highest stony declivities of our Alps".

Among ornithomimids are the genera Struthiomimus as well as Ornithomimus, and "Orcomimus." The birds known from the formation are Avisaurus, Brodavis baileyi, and two unnamed hesperornithoforms, possibly Potamornis. Only three oviraptorosaurs are from the Hell Creek Formation, Anzu, Leptorhynchos and third and undescribed specimen, very similar to Gigantoraptor, from South Dakota. However, only fossilized foot prints were discovered as of 2016.

Somatochlora dido is a species of dragonfly in the family Corduliidae. It is known from southeastern China and northern Vietnam, but populations in Vietnam may alternatively represent a separate, undescribed, species. S. dido has sometimes been treated as synonymous with S. taiwana from Taiwan, but more recent publications have treated them as separate species. S. shennong is also closely related.

There are currently 63 species recognized in the genus Telmatobius, but the validity of some species is questionable and it is likely that undescribed species remain.De la Riva (2005). Bolivian frogs of the genus Telmatobius: synopsis, taxonomic comments, and description of a new species. Monogr. Herpetol. 7:65-101.Sáez, Fibla, Correa, Sallaberry, Salinas, Veloso, Mella, Iturra, and Méndez (2014).

By the time the Emsian epoch starts, only a few genera, such as Duyunolepis and Wumengshanaspis, survive, with most others already extinct. The last galeaspid is an as yet undescribed species and genus from the Fammenian epoch of the Late Devonian, found in association with the tetrapod Sinostega and the antiarch placoderm Remigolepis, in strata from the Northern Chinese province of Ningxia.

Houghton Mifflin Company, Boston, Massachusetts. It is also found in Panama, where it is endemic to the central cordillera and western Pacific lowlands, although this is most likely an undescribed species. They occupy grasslands, lakeshores, and marshes.

Nepenthes mikei was discovered on Mount Pangulubao in September 1989 by Bruce Salmon, Mike Hopkins, and Ricky Maulder, during a Nepenthes expedition to Sumatra. On this trip, the team also found two other undescribed Nepenthes taxa on the mountain: N. ovata and a plant they named N. xiphioides. The latter is now considered a heterotypic synonym of N. gymnamphora.McPherson, S.R. 2009.

11(3-4): 325–350 The São Domingos karst in the upper Tocantins River basin is home to an unusually high number of cavefish species (more than any other region in the Americas): Ancistrus cryptophthalmus, several Ituglanis species, Pimelodella spelaea, Aspidoras mephisto, an undescribed Cetopsorhamdia species and Eigenmannia vicentespelaea.Romero, Aldemaro, editor (2001). The Biology of Hypogean Fishes. Developments in Environmental Biology of Fishes.

Nudibranchs of Southern Africa The South African animals differ in having six instead of four papillae projecting from the frontal margin of the head, plus details of the coloration. These animals have been shown to be an undescribed species by studies in 2014 and 2020.Palomar, G.; Pola, M.; Garcia-Vazquez, E. (2014). First molecular phylogeny of the subfamily Polycerinae (Mollusca, Nudibranchia, Polyceridae).

Pulchrana siberu, also known as the Siberut Island frog, is a species of true frog, family Ranidae. It is found in the Mentawai Islands, off the Sumatran west coast (Indonesia), including the eponymous Siberut Island. It possibly occurs in Sumatra itself, although the latter records seem to refer to an as- yet-undescribed species. Similarly, earlier records from Malaysia refer to Pulchrana centropeninsularis.

These accommodate a significant number of uncommon or restricted species. The nature reserve is the type locality for an undescribed species of daisy bush (Olearia sp. 2, Sentry Box Hill) and contains populations of the rare Australian anchor plant Discaria pubescens. Other notable plant occurrences include Acacia alpina, Bossaiea procumbens, Epacris robusta, Grevillea diminuta, a distinctive form of Montia australasica and Viola improcera.

The genus was named in 1969 by José Bonaparte as an as yet undescribed nomen nudum. The first description followed in 1970, making the name valid, the type species being Pterodaustro guiñazui. The generic name is derived from Greek pteron, "wing" and Latin auster, "south (wind)". The elements are combined as a condensed pteron de austro, "wing from the south".

Prasophyllum validum, commonly known as the Mount Remarkable leek orchid, is a species of orchid endemic to South Australia. It has a single tubular leaf and up to forty five green to yellowish-green flowers with a white labellum. A similar leek orchid occurring in Victoria, previously included in this species, is known recognised as the undescribed Prasophyllum sp. aff. validum.

It was formerly assigned to Myotis nigricans until a 2017 study revealed that it was a distinct, previously unknown species. It is the sister species to a clade containing M. cf. handleyi, M. nesopolus, and 3 possibly undescribed species from South and Central America. It can be distinguished from all other Caribbean Myotis by its small skull and steeply sloping frontals.

Melpomene is a genus of funnel weavers first described by O. Pickard-Cambridge in 1898. They range from southwestern U.S. (southern Arizona to western Texas) to Panama and can grow up to long. Roth and Brame noted that, with many undescribed species, the genus appears to be a catchall or "wastebasket taxon" for several unrelated species that may represent several genera.

This eremophila occurs mostly commonly in Western Australia where it is found from near Rawlinna to Mount Magnet, growing in the Gibson Desert, Little Sandy Desert, Murchison, Nullarbor Plain and Yalgoo biogeographic regions. It is also found in the extreme central west of South Australia. A single record from the Northern Territory may be a new, as yet undescribed species.

The plains leek orchid grows in grassy places and in shrubland and is common and widespread, mostly in the west of South Australia. It is less common in Victoria, occurring in the south-west of that state. Some authorities regard this species as a South Australian endemic, and collections in Victoria to be of a closely related, as yet undescribed species.

The Bell-Irving volcanic district is located in the upper Bell-Irving River watershed. It is considered part of the Northern Cordilleran Volcanic Province. Between 1992 and 2004 fourteen previously undescribed volcanic occurrences were found, documented, and assigned to the Bell-Irving volcanic district. All fourteen have pillow lava deposits and/or volcaniclastic rocks, and were probably created by Pleistocene alpine glaciovolcanic eruptions.

Limnonectes grunniens (common name: Amboina wart frog) is a species of frog in the family Dicroglossidae. It is found in Sulawesi, Molucca Islands, and New Guinea (Indonesia and Papua New Guinea). Frogs from Sulawesi may represent a different, undescribed species. Limnonectes grunniens is a semi-aquatic frog living and breeding near and in streams, swamps and pools in tropical rainforest.

The Caelifera includes some 2,400 valid genera and about 11,000 known species. Many undescribed species probably exist, especially in tropical wet forests. The Caelifera have a predominantly tropical distribution with fewer species known from temperate zones, but most of the superfamilies have representatives worldwide. They are almost exclusively herbivorous and are probably the oldest living group of chewing herbivorous insects.

The fruits, which appear in autumn, are about 8 mm in diameter. These are eaten by small mammals and birds. The species occurs in subalpine areas of the southern highlands, often in association with Eucalyptus pauciflora. The species was formally described in 1855 by Victorian Government Botanist Ferdinand von Mueller in his paper Definitions of rare or hitherto undescribed Australian plants.

"Discomedusae" (all rhizostomids), from Ernst Haeckel's Kunstformen der Natur, 1904 Discomedusae is a subclass of jellyfish in the class Scyphozoa. It is the sister taxon of Coronamedusae. Discomedusae contains about 155 named species and there are likely to be many more as yet undescribed. Jellyfish in this subclass are much more likely to have swarming events or form blooms than those in Coronamedusae.

Ptychadena nana is a species of frog in the family Ptychadenidae. It is endemic to Ethiopia. It is only known with certainty from its type locality, Arussi Mountains, in the Ethiopian Highlands; these mountains are also referred to as the Arsi Mountains. There is uncertainty regarding reports from elsewhere (in particular, Bale Mountains), which perhaps refer to other, possibly undescribed species.

Neuroleon sansibaricus type specimen from the Bavarian State Collection of Zoology Neuroleon is a large and complex genus of antlions in the subfamily Myrmeleontinae. There are more than 150 described species from Europe, Asia and Africa, and there are many undescribed taxa. Where the biology of the larvae is known, they live freely in sand or in sheltered rock crevices.

The Little Colorado River Sucker or Little Colorado sucker ("Catostomus sp.3") is a scientifically undescribed species of North American freshwater fish very similar to the flannelmouth sucker (Catostomus latipinnis) but without the flannelmouth's distinct fleshy lips. The Little Colorado sucker is native to the upper region of the Little Colorado River in Arizona, but was also introduced into the Salt River.

"Kagasaurus" (meaning "Kaga lizard") is the informal name given to an as yet undescribed genus of dinosaur from the Early Cretaceous. It was a theropod which lived in what is now Japan. The type species was named by Hisa in 1988, but is known from only two teeth. Since "Kagasaurus" has never been formally described, it is considered a nomen nudum.

"Magulodon" is the name given to an as yet undescribed genus of dinosaur from the Early Cretaceous (Aptian to Albian stages, approximately 112 million years ago). It was a possible ornithischian, either an ornithopod or basal ceratopsian, which lived in what is now Maryland, in the United States. The type species, "Magulodon muirkirkensis", was coined by Kranz in 1996.Kranz, P. (1996).

"Megacervixosaurus" (meaning "big neck lizard") is the informal name given to an as yet undescribed genus of herbivorous dinosaur from the Late Cretaceous. It was a titanosaur sauropod which lived in what is now China. The type species, "Megacervixosaurus tibetensis", was coined by Chinese paleontologist Zhao Xijin in 1985. "Megacervixosaurus" has never been formally described, and remains a nomen nudum.

The range of the balloon shark is likely restricted to the waters off the South African province of KwaZulu- Natal and Mozambique. Additional records from the Gulf of Aden and off Vietnam appear to represent different, yet-undescribed species. This common, bottom- dwelling shark inhabits the continental shelf and upper continental slope, at depths of . It favors sandy and muddy substrates.

"Phylogenetics of the Tetraplasandra Group (Araliaceae) Inferred from ITS, 5S-NTS, and Morphology". Systematic Botany 32(2):464-477. In 2010, all of these nine species were included in Polyscias subgenus Tetraplasandra, a subgenus of 21 species in the large genus Polyscias, which will comprise about 250 species, when about 90 undescribed species are published.Porter P. Lowry II and Gregory M. Plunkett. 2010.

This species was first collected by John Wrigley of the Australian National Botanic Gardens in 1968. Wrigley took cuttings and the plant was established in cultivation at the gardens. Later, Ernest Charles Nelson worked with Wrigley while developing a comprehensive taxonomic revision of Adenanthos. He recognised the cultivated plants as an undescribed species, and in 1973 revisited Wrigley's collection location to collect further native specimens.

Although it is not known with certainty, the species is probably mycorrhizal. Fruit bodies grow on the ground singly or scattered, under conifers, especially western hemlock, and deciduous trees, particularly tanoak. Fruiting usually occurs in September and November. The species is primarily known from the Pacific Northwest region of North America, although it (or a very similar, undescribed species) has been reported from Kansas.

However, Henrietta's suspicious (and crooked) lawyer Andy McPherson is a problem for Henry, as his Uncle Harry plots with the shyster to prove to Henrietta that Henry only wants her for her money. They fail, and Henrietta marries Henry. On their honeymoon, Henrietta discovers what may be an undescribed species of fern. Murder never far from his mind, Henry takes charge of his wife's life.

This information is not available from fossil specimens, and the palaentological taxonomy is founded principally on the venation of the hindwings. The Caelifera includes some 2,400 valid genera and about 11,000 known species. Many undescribed species probably exist, especially in tropical wet forests. The Caelifera have a predominantly tropical distribution with fewer species known from temperate zones, but most of the superfamilies have representatives worldwide.

The female's tail feathers are longer and more pointed at the tip than those of the male. The juvenile purple-throated cotinga resembles a paler, buffier female; the plumage of the immature is undescribed. The adult purple-throated cotinga is about in length and weighs an average of . The cotinga has a very wide bill with a strongly arched culmen and weakly developed rictal bristles.

Davidsonia pruriens, also known as ooray, Davidson's plum, or Queensland Davidson's plum, is a medium-sized rainforest tree of northern Queensland, Australia. The leaves are large and compound. The edible dark burgundy colored fruit is produced in large clusters from the branches or the trunk, depending on the type. There are at least two distinct forms, with a suggestion that one of these is an undescribed species.

It was described as a new species in 2008 by Tatyana A. Trofimova from a two male specimens collected by Henry John Elwes from the Kullu Valley of northern India in 1913, which had sat undescribed at the Zoological Institute of the Russian Academy of Sciences, St. Petersburg for the past century. The holotype was designated by Trofimova as one of the two specimens.

Wangolepis sinensis is a nomen nudumJanvier, Philippe, et al. "Devonian fish (Placodermi, Antiarcha) from Tra Ban Island (Bai Tu Long Bay, Quang Ninh Province, Vietnam) and the question of the age of the Dô Son Formation." Journal of Asian Earth Sciences 21.7 (2003): 795-801. referring to as yet formally undescribed, primarily Early Silurian-aged fossils of what are agreed to be of a primitive placoderm.

Orange goo near remote Alaska village ID'd as eggs, Associated Press, August 8, 2011 Later, officials of the National Oceanic and Atmospheric Administration (NOAA) confirmed that the orange colored materials were some kind of crustacean eggs or embryos, but subsequent examination resulted in a declaration that the substance consisted of spores from a possibly undescribed species of rust fungus, later revealed to be Chrysomyxa ledicola.

This has long been considered to be a variable plant that was likely a species complex, with individuals actually belonging to several undescribed species. In 2008 some populations were studied, characterized as new species, and renamed Zamia hamannii, Zamia imperialis, and Zamia nesophila.Haynes, J. L. and G. Holzman. (2008). Taxonomical, nomenclatural and biogeographical revelations in the Zamia skinneri complex of Central America (Cycadales: Zamiaceae).

In his 1997 monograph, Nepenthes of Borneo, Charles Clarke lists the undescribed taxon "Nepenthes sp. A", which has been recorded from Gunung Mulu National Park in Sarawak. It bears a close resemblance to N. fusca and may be conspecific with it, although its colouration is unusual for the species. The pitchers of this plant match J. H. Adam and C. C. Wilcock's descriptionAdam, J.H. & C.C. Wilcock 1991.

Cepola is a genus of marine fish in the bandfish family Cepolidae. The name red bandfish is applied to all members of this genus, but particularly C. macrophthalma, and generally not C. australis, which is also known as the Australian bandfish. Five species are recognised, and there may be a sixth, as yet undescribed, from the waters near Bermuda. The oldest recorded recipe is for C. macrophthalma.

Euacanthellinae is a subfamily of leafhoppers, native to Australia, New Caledonia and Madagascar, and adventive in New Zealand. There are 11 described species in 4 genera. 10 species in 3 genera are native to Australia, Madagascar has a single endemic genus/species, and New Caledonia has a single undescribed species of uncertain generic placement. New Zealand has a single species, Euacanthella palustris, adventive from Australia.

However, it also reproduces asexually by forming colonies. The mature seeds of the plant remain undescribed and unknown. This species is entirely endemic to the summits of Toolbrunup Peak and Bluff Knoll in the Stirling Range National Park, a range of mountains in Southwestern Australia. It is specifically limited to extremely high elevations, such as the cloud-lines of the mountain summits in its range.

However, there are elements of the cart and the horse here - which > should come first? Break up Luciola based on narrow analyses, or wait until > more analyses are available? It is our contention that those Luciolinae > species which do not fit elsewhere should either be described as Luciola sp. > or remain undescribed until such time as phylogenetic analyses indicate a > repeatable pattern of subdivisions with Luciola.

The Cladocera are an order of small crustaceans commonly called water fleas. Over 650 species have been recognised so far, with many more undescribed. They first appeared before the Permian period, and have since invaded most freshwater habitats. Some have also adapted to a life in the ocean, the only members of Branchiopoda to do so, even if several anostracans live in hypersaline lakes.

Albomagister is a genus of fungi in the family Tricholomataceae. The genus contains just one named species known from Tennessee and North Carolina, however two other undescribed species have been sequenced. Albomagister was described by mycologists Marisol Sánchez-García, Joshua Birkebak & P. Brandon Matheny in 2014 with Albomagister subaustralis as the type species. Albomagister has a tricholomatoid stature and white gills with adnexed attachment.

Kushlukia is an extinct genus of prehistoric bony fish, closely related to the luvar, that lived during the lower Eocene. K. permira is from Eocene portion of the Danata Formation Lagerstatten (which otherwise spans the Thanetian epoch of the Paleocene to the Lowest Eocene), of Turkmenistan. A second, as yet undescribed species is from the Fuller's Earth formation Lagerstatten in the Barmer District, of Ypresian Rajasthan, India.

Teuthidodrilus samae is the only species classified in the genus Teuthidodrilus. It belongs to the family Acrocirridae of the class Polychaeta in the phylum Annelida. It is classified along with the genus Swima in the "swimming clade" within the family Acrocirridae. A similar undescribed and uncollected specimen observed from off western India by the Hercules 7 ROV in 2004 may represent a second species in the genus.

Its weight was calculated at , , and in separate works. The second skeleton, MWC 1, was somewhat smaller than UMNH VP 5278 and might have been in weight. The third, yet undescribed, specimen BYUVP 12893 was claimed to be the largest yet discovered, although estimates have not been published. Another specimen (ML 352), discovered in Portugal in 2000, was estimated at in length and in weight.

Bufoides meghalayanus is a species of toad in the family Bufonidae, the true toads. It is also known as the Mawblang toad, rock toad, or Khasi Hills toad. It is endemic to northeastern India where it is known from Meghalaya and Mizoram. However, records from Mizoram may represent an undescribed species, and this species might have a very restricted range in the Khasi Hills near Cherrapunji.

Muleshoe virus (MULEV) is a novel, single-stranded, enveloped, negative-sense RNA orthohantavirus.Rawlings JA, Torrez-Martinez N, Neill SU, Moore GM, Hicks BN, Pichuantes S, Nguyen A, Bharadwaj M, Hjelle B.. Cocirculation of multiple hantaviruses in Texas, with characterization of the small (S) genome of a previously undescribed virus of cotton rats (Sigmodon hispidus). Am J Trop Med Hyg. 1996 Dec;55(6):672–9.

It lay undescribed for nearly two decades before it was described in 2016Ilaria Paparella, Erin E. Maxwell, Angelo Cipriani, Scilla Roncacè and Michael W. Caldwell (2016) - The first ophthalmosaurid ichthyosaur from the Upper Jurassic of the Umbrian–Marchean Apennines (Marche, Central Italy). Geological Magazine (advance online publication) \- this paper was eventually published in 2017. The holotype is now housed at the Spaelaeo-Palaeontologic Museum in Genga.

It has typically been considered a subspecies of the painted parakeet. While reviewing this group, Joseph (2002) discovered that an undescribed population existed in northern Peru (later also found in far south-eastern Ecuador). It was described as Pyrrhura peruviana (Hocking, Blake and Joseph, 2002). It was further recommended that P. roseifrons should be considered a monotypic species instead of a subspecies of P. picta.

The thin, grey legs are not as long as with other avocet species, but the long thin black bill is upturned at the end. The sexes are similar, and the juvenile plumage is undescribed. The colour pattern is similar to that of the local subspecies Himantopus himantopus melanurus of black-winged stilt, but that bird has very long red legs a white tail and a straight bill.

Though the genus is considered monophyletic at this time, an undescribed new species has been reported. In a 1978 publication Dr. V. Zherikhin reported, but did not illustrate or figure, a scorpionfly specimen which belongs to a new species of Dinopanorpa from the Paleocene Tadushi Formation in Primorsky Krai. However, since the 1978 reference no further study of the specimen has occurred and the species remains unnamed.

Chicks are undescribed. The bird is named for its most common call, a "loud, flute-like whistled kleeer-er" or "a high, reedy, complaining whistle, often doubled or uttered in a ser[ies], wueeee, wueeee,.…, easily imitated" or "a distinctive, characteristic, far-carrying, melodious whistle" that "can be rendered 'kee, kee, kee.'" It may also give "a slow, drawn-out whistle" when taking off.

The black-spotted torpedo, Torpedo fuscomaculata, is a poorly known, uncommon species of electric ray in the family Torpedinidae, known for being capable of generating an electric shock. It is endemic to southern Africa and possibly several small Indian Ocean islands, although the latter reports may represent undescribed new species. Its appearance is similar to the Gulf torpedo (Torpedo sinuspersici), but it is duller in coloration.

It nests in a long tunnel in a bank or the side of a mammal burrow. The clutch size and eggs are undescribed. Rufous motmots feed on insects, lizards, fish, crabs, and also consume many fruits, especially those of palms and Heliconias. These birds often sit still on a canopy perch, and in their dense forest habitat can be difficult to see, despite their size and colour.

Albertosaurus is a member of the theropod family Tyrannosauridae, in the subfamily Albertosaurinae. Its closest relative is the slightly older Gorgosaurus libratus (sometimes called Albertosaurus libratus; see below). These two species are the only described albertosaurines; other undescribed species may exist. Thomas Holtz found Appalachiosaurus to be an albertosaurine in 2004, but his more recent unpublished work locates it just outside Tyrannosauridae, in agreement with other authors.

Allobates brunneus (common name: Chupada rocket frog) is a species of frog in the family Aromobatidae. It is found in the southern Amazon drainage in Brazil to Mato Grosso and Amazonas and into extreme northern Bolivia. It has been often confused with other species, including undescribed ones. Its natural habitats are margins of lakes and pools of stagnant water in tropical rainforest and seasonally flooded forest.

Until 2015 three Crossodactylus species were known from the Espinhaço Mountains: Crossodactylus trachystomus (not observed in the field since the mid 1980s), an undescribed species most similar to C. trachystomus, and Crossodactylus bokermanni described as a new species in 1985. Re-analysis of old samples and analysis of new samples could not show consistent differences between these taxa, for which Crossodactylus trachystomus is the valid name.

Five species of Paracatenula have been described - P. erato, P. kalliope, P. polyhymnia, P. urania and P. galateia, named after muses and nymphs of the Greek mythology. Several more species have been morphologically and molecularly identified, but are not formally described. The best studied species are P. galateia from the Belize barrier reef and a yet undescribed species P. sp. santandrea from the Italian Island of Elba.

Furcifer nicosiai was initially described by Jesu, Matioli and Schimmenti in 1999 as a new large chameleon inhabiting western Madagascar. The type specimens were collected in February and March 1997, during the rainy season. Furcifer oustaleti, Furcifer verrucosus and Furcifer nicosiai group of Chamaeleonidae may well contain other undescribed species and needs a major revision according to the IUCN Red List of Threatened Species.

Corallorhiza bentleyi is a rare species of orchid known deciduous forests in the mountains of Virginia and West Virginia.Kew World Checklist of Selected Plant FamiliesFlora of North America v 26 p 634, Corallorhiza bentleyiBiota of North America Program, distribution map for Corallorhiza bentleyi It was undescribed until 1999.Freudenstein, J.V. 1999.

Amnirana is a genus of frogs in the family Ranidae, "true frogs". The genus is primarily found in Sub-Saharan Africa, but one species occurs in parts of southern and southeastern Asia. Some of the African species are widespread but contain undescribed cryptic diversity. Most (but not all) species have a white upper lip, and the genus is sometimes known as the white-lipped frogs.

Family Plagiaulacidae is known from the Upper Jurassic (North America) to Lower Cretaceous (Europe), being represented by Plagiaulax, Bolodon, and Morrisonodon. Family Albionbaataridae is known from the Upper Jurassic to Lower Cretaceous of Europe and Asia, (China – undescribed, 2001). These were shrew-sized Multituberculates, with some similarities to the paulchoffis. Members of the family Eobaataridae display dental similarities with members of Paracimexomys group, (Cimolodonta).

Breeding pairs communicate by making characteristic duetting calls. Due to the great similarity of these calls to those of Dian's tarsier (Tarsius dentatus), the two species are thought to be closely related. Studies of the calls of tarsiers on Sulawesi and the surrounding islands enable cryptic species to be distinguished from one another, and indicate that there may be four as yet undescribed species.

Yemenite deaf-blind hypopigmentation syndrome is a condition caused by a mutation on the SRY-related HMG-box gene 10 (not SOX10). It was characterized in 1990, after being seen in two siblings from Yemen who presented with a "hitherto undescribed association of microcornea, colobomata of the iris and choroidea, nystagmus, severe early hearing loss, and patchy hypo- and hyperpigmentation." Some sources affirm SOX10 involvement.

Do Dwarf Chameleons (Bradypodion) Show Developmental Plasticity? Zoological Society of Southern Africa. An undescribed dwarf chameleon population from Gilboa and Karkloof Forests in KwaZulu-Natal seems closely related to both B. melanocephalum and B. thamnobates. It appears as if they radiated quite recently from a common ancestor, which probably was much like the Midlands form in appearance (as this is the most plesiomorphic of them).

Much remains unknown about this small creature. It is part of a closely related Cuban group that contains five additional described species (E. cubanus, E. etheridgei, E. jaumei, E. limbatus and E. orientalis) and at least one undescribed species; most of which are of tiny size, relatively brightly colored and possibly aposematic (at least E. iberia and E. orientalis have alkaloid toxins in their skin).

Pagurus sinuatus is a large species of hermit crab, and normally inhabits rounded gastropod shells. It is distinguished from other hermit crab species in Australia by its solid, hairy chelipeds (claw-bearing appendages), although there may be further undescribed species within its range. The hermit crab's body is orange and red, with patches of red or violet colour. The pereiopods (walking legs) are banded.

The second specimen was designated LACM/CIT 2760. Discovered in 1939, it was made up of elements of the skull and limbs. Due to its smaller size, it may have been a juvenile. It is one of three known dinosaurs from western coast of the United States, the other two being the Campanian Aletopelta coombsi and an undescribed species of tyrannosaur from Washington state.

Huttonia is a monotypic genus of ecribellate South Pacific araneomorph spiders in the Huttoniidae family containing the single species, Huttonia palpimanoides. Although only one species is described, there are still about twenty more undescribed species. It was first described by Octavius Pickard- Cambridge in 1880, and has only been found in New Zealand. Originally placed with the ant spiders, it was moved to the Huttoniidae in 1984.

Catton Grove Chalk Pit is a geological Site of Special Scientific Interest on the northern outskirts of Norwich in Norfolk. It is a Geological Conservation Review site. This Cretaceous site exposes rocks dating to the late Campanian, around 75 million years ago, and it is the type site for the Catton Sponge Bed. Its well preserved fossils include many undescribed sponges and important ammonites.

All Bristoliinae occur in the late Lower Cambrian (Olenellus-zone) of the former paleocontinent Laurentia. Fremontella halli is known from eastern Laurentia (Rome Formation, Alabama, USA). All other species are known from western Laurentia: Lochmanolenellus mexicana from northern Mexico and South- East California, the species of Bristolia from southeastern California and southern Nevada, and an undescribed Bristolia-species from the North-West Territories, Canada.

The Darling Downs funnel-web spider was described by Hickman in 1964 as Atrax infensus before being moved to the genus Hadronyche in 1988. The type specimen is a male spider that was collected in Toowoomba, Queensland, in 1963. Within the genus, it is a member of the infensa group, which contains several described and undescribed species in central New South Wales and southern Queensland.

"Hisanohamasaurus" (meaning "Hisano-hama lizard") is the informal name given to an as yet undescribed genus of dinosaur from the Late Cretaceous. It is a nomen nudum known only from teeth that first appeared in a general-audience dinosaur book by David Lambert in 1990. Although initially identified a diplodocid,Zhiming, Dong; Y. Hasegawa; and Y. Azuma (1990). The Age of Dinosaurs in Japan and China.

"Lijiagousaurus" (meaning "Lijiagou lizard") is the informal name given to an as yet undescribed genus of herbivorous iguanodontian dinosaur from the Late Cretaceous of what is now Sichuan, China. It has not been formally described yet, but the formal publication is forthcoming, from Chinese paleontologist Ouyang Hui. "Lijiagousaurus" was only briefly mentioned in the Chongqing Natural History Museum guidebook (2001) and is thus a nomen nudum.Anonymous (2001).

"Likhoelesaurus" (meaning "Li Khole lizard") is the name given to an as yet undescribed genus of archosauriform, either a dinosaur or rauisuchian, from the Late Triassic of what is now South Africa. The name was coined by Ellenberger in 1970, and the "type species" is "Likhoelesaurus ingens".Ellenberger, 1970. Les niveaux paléontologiques de première apparition des mammifères primoridaux en Afrique du Sud et leur ichnologie.

A coralicida was originally isolated as the cause of white plague in coral in the Caribbean in 1998. In 2003, the 16s rRNA sequence of the bacterium was compared to other known sequences to determine its taxonomic relationship to other bacteria. It was found to be a previously-undescribed member of the order Rhizobiales and was classified under the newly created genus Aurantimonas as Aurantimonas coralicida.

Microcambeva is thought to be widespread along coastal basins of southern, southeastern, and eastern Brazil. M. barbata originates from Atlantic coastal drainages of Rio de Janeiro and Espírito Santo states in Brazil. M. ribeirae originates from the Ribeira do Iguape River basin of southeastern Brazil. Two undescribed species of Microcambeva are known from the Doce River basin in Minas Gerais state and Jucuruçu River in Bahia state.

Carson, et al. (2015). The rediscovery and precarious status of the Chihuahua dwarf crayfish Cambarellus chihuahuae. Occasional Papers of the Museum of Southwestern Biology 12: 1-7. C. alvarezi and four undescribed, extinct Cambarellus species were restricted to desert spring systems in southwestern Nuevo León; each one shared its habitat with a Cyprinodon pupfish (these are also fully extinct or extinct in the wild).

With the majority of biological species remaining undescribed the classification and quantification of geodiversity is not an abstract exercise in geotaxonomy but a necessary part of mature nature conservation efforts, which also requires a geoethical approach.Peppoloni S. and Di Capua G. (2012), "Geoethics and geological culture: awareness, responsibility and challenges". Annals of Geophysics, 55, 3, 335-341. . According to Ponciano et alPonciano L.C.M.O. et al.

In 2013 she became a research zoologist and curator at the National Museum of Natural History in the Department of Invertebrate Zoology. Picture of an undescribed species of Grania (Clitellata) Phillips helped oversee the transfer of the United States National Parasite Collection to the Natural History Museum. About 20 million specimens were moved. They are now sorting through the specimens to organize and maintain the collections.

Cheke's wood rail (Dryolimnas chekei), also known as Sauzier's wood rail, is an extinct species of rail which was endemic to the Mascarene island of Mauritius. It was described by British ornithologist Julian P. Hume in 2019, and the name honours British ecologist Anthony S. Cheke. Previously mentioned as an undescribed extinct taxon and provisionally named Sauzier's wood-rail or Dryolimnas sp., until it was described as new species in 2019.

New cavefish species are described with some regularity and undescribed species are known. As a consequence, the number of known cavefish species has risen rapidly in recent decades. In the early 1990s only about 50 species were known, in 2010 about 170 species were known, and by 2015 this had surpassed 200 species. It has been estimated that the final number might be around 250 obligate cavefish species.

Hyperthermophilic bacteria have been found on Macdonald, including Archaeoglobus, Pyrococcus, Pyrodictium and Thermococcus as well as previously undescribed species. These bacterial communities contain both hydrogen- or sulfur- consuming autotrophs and heterotrophs and appear to be capable of long-range propagation, considering that relatives of the species found are known from Vulcano in Italy. Aside from hyperthermophiles, craniids, corals, polynoids and sponges have been found in the summit area of Macdonald.

Skull of an undescribed and unnamed Nasutoceratopsini exhibited in the Museo del Mamuth in Chihuahua City, from the municipality of Aldama. Centrosaurine fossils have mostly been found in Western North America (Alberta, Montana, & Alaska). In the United States, two taxa, Diabloceratops and Machairoceratops, have been found as far south as Utah. Yehuecauhceratops is a nasutoceratopsin from Coahuila, Mexico and the southernmost occurrence of a centrosaurine in North America.

Narke is a genus of electric rays in the family Narkidae, found in the western Indo-Pacific and off southern Africa. They have nearly circular pectoral fin discs and short, thick tails with large caudal fins, and can be identified by their single dorsal fin (a trait shared only by Typhlonarke within the family). There are three described species, as well as a fourth undescribed dwarf species from Taiwan.

Classification of the 63,650 (as of 2018) staphylinid species is ongoing and controversial, with some workers proposing an organization of as many as 10 separate families, but the current favored system is one of 32 subfamilies, about 167 tribes (some grouped into supertribes), and about 3,200 genera. About 400 new species are being described each year, and some estimates suggest three-quarters of tropical species are as yet undescribed.

Given the huge differences in climatic and riverine conditions, careful work on species identity is needed to establish if these mahseer are also Tor tor, or an undescribed species. It is a large fish, reaching at maturity, but lengths of have been recorded, but the maximum length is 200 cm.Fishbase-Tor tor The fish is well armoured by their record large scales, each reaching up to in length.

Other, as yet undescribed material included two finds of several juveniles huddled together, evidently killed by a sandstorm. Whereas ankylosaur skeletons have often been preserved laying on their back, most Pinacosaurus juveniles are found on their belly in a resting position, with the legs tucked in. Juvenile specimens under excavation in 1990, with quarry map Because of the many finds, in principle the entire juvenile skeleton is known.

In general, metagenomic sequencing is most useful and cost efficient for pathogen discovery when at least one of the following criteria are met: # the identification of the organism is not sufficient (one desires to go beyond discovery to produce data for genomic characterization), # a coinfection is suspected, # other simpler assays are ineffective or will take an inordinate amount of time, # screening of environmental samples for previously undescribed or divergent pathogens.

In 2006, in the hopes of saving the species, the then undescribed specimens of E. rabborum that teams of herpetologists collected were sent to captive breeding facilities in the El Valle Amphibian Conservation Centre (EVACC), Zoo Atlanta, and the Atlanta Botanical Garden. However, these efforts ultimately proved to be futile. The frogs thrived in these facilities but never mated. The last female died in 2009 in the Atlanta Botanical Garden.

Males also develop small bumps upon reaching sexual maturity. L. fabricii can be distinguished from other snailfishes by its dark peritoneum and by the number of soft rays on its anal fin. Although the dark peritoneum is unique among Arctic snailfish, L. fabricii as presently defined is a complex that comprises several species that all have it (some of these have scientific names that can be resurrected, but others remain undescribed).

The male palpal organ of many Australian Afraflacilla species has a large, circling embolus (inseminating sclerite) and retro- lateral tibial apophysis (side spike). Some undescribed Australian Afraflacilla species have greatly enlarged segments of the first pair of legs, and sometimes massive spurs coming from underneath the tibia and metatarsus (third and second last leg segments). Enlarged leg-one segments are also a feature of Pseudicius, a genus widespread outside Australia.

Nurteria is a genus of flies in the family Dolichopodidae, found in the Afrotropical realm. Three species are currently known in the genus, but there are also numerous undescribed species of the genus from southern Africa. It was originally described in the subfamily Diaphorinae, though it possesses some features of the Sympycninae. The genus was originally described by Octave Parent in 1934 with the name Turneria, including two species.

There are 20 described species in the genus Stenopelmatus,Genus Stenopelmatus and at least 30 more as yet undescribed. The family Stenopelmatidae contains several Old World genera, but only the genera in the subfamily Stenopelmatinae (all New World) are referred to as Jerusalem crickets. Other families in the same superfamily (Stenopelmatoidea) in Australia and New Zealand include the wētā and king crickets. They are similar to Stenopelmatus in many respects.

These isolated islands are not rich in wildlife diversity but are home to a large population of subantarctic fur seal. They are an important breeding ground for the Indian yellow-nosed albatross, flesh-footed shearwater, gentoo penguin, northern rockhopper penguin (Eudyptes moseleyi) great skua, Antarctic tern and the endemic Amsterdam albatross. They were formerly home to two endemic ducks: the Amsterdam wigeon and an undescribed species on Île Saint-Paul.

The third, an undescribed species of Acroclisoides, may attack C. simplex eggs directly as a primary parasitoid, or it may be attacking eggs previously parasitised by one of the first two parasitoid species (in which case it would be a hyperparasitoid). A species of braconid wasp, Aridelus sp., has been recorded from 5th instar nymphs, and a species of tachinid fly, Alophora sp., has been recorded from adult C. simplex.

Heterobathmia is a genus of Lepidoptera. It is the only genus in the suborder Heterobathmiina, as well as in the superfamily Heterobathmioidea and in the family Heterobathmiidae. Primitive, day-flying, metallic moths confined to southern South America, the adults eat the pollen of Nothofagus or southern beech and the larvae mine the leaves (Kristensen, 1983, 1999). Most known species are undescribed (but see Kristensen and Nielsen, 1978, 1998).

In 2004 Lauri Kaila attempted to use cladistics to approximate the phylogeny of the superfamily Gelechioidea, using 193 morphological traits. In this work the family Batrachedridae appeared paraphyletic, because the family Coleophoridae sensu stricto was nested within the Batrachedridae. Kaila used an undescribed species from Australia which mined in the plant Lomandra longifolia, provisionally called "Batrachedra eustola", in his analysis. This taxon specifically helped to cause the Batrachedridae to be paraphyletic.

This species is associated with fast-flowing creeks and streams in rainforests in northern Queensland. The call for this species is unknown, but is likely to be similar to that of the closely related waterfall frog, (Litoria nannotis). Tadpoles of this species are undescribed, although they would theoretically look similar to those of L. nannotis–with a large oral disc and a streamlined body, an adaptation to fast-flowing streams.

One ankylosaurian and two nodosaurians are known, Ankylosaurus, Denversaurus and possibly Edmontonia. Multiple genera of ceratopsians are known from the formation, the leptoceratopsid Leptoceratops and the chasmosaurines Nedoceratops, Torosaurus, Triceratops, and Tatankaceratops. Hadrosaurs are common in the Hell Creek Formation, and are known from multiple species of the ornithopod Thescelosaurus, and the hadrosaurids Edmontosaurus, and an undescribed genus similar to Parasaurolophus. Five pachycephalosaurians have been found in the Hell Creek Formation.

Tenuibranchiurus lives in coastal wallum swamps, and stays among the sedges rather than in more open water. Its habitat is highly fragmented, as land is used for the expansion of Brisbane and the Sunshine Coast, and Tenuibranchiurus glypticus is therefore listed as an endangered species on the IUCN Red List. Additional populations have been found at the periphery of its range, but these are thought to represent new, undescribed species.

One of the most commonly found species is the black coral (Pocillopora damicornis). Large corals are rare and mostly found at the bottom of the reefs. Six other species of coral were found including Pocillopora capitata, Pocillopora meandrina, Pocillopora verrucosa, Pavona gigantea, Porites panamensis and an undescribed species noted as Pocillopora sp. Colonies of Porites panamensis were extremely scarce, encrusting, and appeared only at depths of less than three meters.

Calling at Curio Bay, New Zealand In spring 2004, a previously undescribed disease killed off 60% of yellow-eyed penguin chicks on the Otago peninsula and in North Otago. The disease has been linked to an infection of Corynebacterium, a genus of bacteria that also causes diphtheria in humans. It has recently been described as diphtheritic stomatitis. However, it seems as if this is just a secondary infection.

Zelenkov (2016) transferred the species Anas denesi Kessler (2013), known from the late Miocene of Hungary, to the genus Aythya. An undescribed prehistoric species is known only from Early Pleistocene fossil remains found at Dursunlu, Turkey;Louchart, Antoine; Mourer-Chauviré, Cécile; Guleç, Erksin; Howell, Francis Clark & White, Tim D. (1998): L'avifaune de Dursunlu, Turquie, Pléistocène inférieur: climat, environnement et biogéographie. C. R. Acad. Sci. Paris IIA 327(5): 341-346.

Commonly known as the Port Macquarie funnel-web spider, Hadronyche macquariensis was described by Mike Gray in 2010, the holotype male having been collected from Taree, New South Wales in January 1978. Within the genus, it is a member of the infensa group, which contains several described and undescribed species in central New South Wales and southern Queensland. Before its description, it was known as Hadronyche sp. 14.

6 in 2008 using a multi-locus analysis of morphology, the results of allozyme electrophoresis and investigation of echolocation call signatures. Referenced as an undescribed taxon, Mormopterus sp. 6 was cited by authors until its recognition as species Mormopterus (Setirostris) eleryi in publications after 2011. Resolution of Australian Molossidae systematics showed that this species, and the east-coast Micronomus norfolkensis, are only distantly related to other Australian mollosid taxa.

It has typically been considered a subspecies of the painted parakeet. While reviewing this group, Joseph (2002) discovered that an undescribed population existed in central Brazil (later also found in north-eastern Bolivia). It was described as Pyrrhura snethlageae (Joseph and Bates, 2002). No diagnostic difference was found between the taxa amazonum and microtera; it was therefore recommend that the latter should be considered a junior synonym of the former.

Combining the two greatly expands the geographical and chronological range of the genus Albertosaurus. Other experts maintain the two genera as separate. Canadian paleontologist Phil Currie claims there are as many anatomical differences between Albertosaurus and Gorgosaurus as there are between Daspletosaurus and Tyrannosaurus, which are almost always kept separate. He also notes that undescribed tyrannosaurids discovered in Alaska, New Mexico and elsewhere in North America may help clarify the situation.

Grotte dei Balzi Rossi (Rochers Rouges) where the Grimaldi skeletons were found. Picture from Nouvelle géographie universelle, 1877 In the late 19th century, several stone age finds of extreme age had been made in the caves and rock shelters around the "Balzi Rossi" (the Red Cliff) near Ventimiglia in Italy.Bisson, M.S. & Bolduc, P. (1994): Previously Undescribed Figurines From the Grimaldi Caves. Current Anthropology no 35(4), pages 458-468.

The family is well represented South America, and Africa. A currently undescribed genus in the western United States may hold an altitude record for the family, being found up to over 11,000 feet (3,300 meters). The genus Anemesia is found only in Central Asia, and Cyrtauchenius reaches from Algeria north to Italy, with one species found in the USA. Angka is endemic to the cloud forest of Doi Inthanon, Thailand.

A male ground wētā, Hemiandrus pallitarsis Ground wētā are classified in the genus Hemiandrus. About 30 species of ground wētā occur in New Zealand, and several very similar (undescribed) ones are found in Australia. They are also very like the Californian Cnemotettix—a similarity perhaps due to their very similar habits and habitat. 14 Hemiandrus species have been described from New Zealand and other distinct populations require further study.

For a long time, the genus Plica was considered to include four species: two relatively widespread ones (Plica plica and Plica umbra) and two tepuis-associated species with narrow distributions (Plica lumaria and Plica pansticta). However, recent research has shown that Plica plica is a cryptic species complex, and four new species were described in 2013. The species count will likely increase as there are still several undescribed species.

Pi5 is a peptide that is purified from the venom of the African scorpion Pandinus imperator.Olamendi-Portugal T, Csoti A, Jimenez-Vargas JM, Gomez-Lagunas F, Panyi G, Possani LD. Pi5 and Pi6, two undescribed peptides from the venom of the scorpion Pandinus imperator and their effects on K(+)-channels. Toxicon 2017 Jul;133:136-144. Pi in Pi5 is short for the 5th identified peptide of the scorpion Pandinus imperator.

In 1994, Commonwealth Scientific and Industrial Research Organisation (CSIRO) chief researchers Peter Last and John Stevens recognized an undescribed Australian swellshark with a variegated color pattern, which they provisionally named Cephaloscyllium "sp. E". Later investigation revealed that "sp. E" in fact constituted two species: the speckled swellshark (C. speccum) and the flagtail swellshark, which was formally described in a 2008 CSIRO publication by Peter Last, Bernard Séret, and William White.

Glyptonotus antarcticus is an unusually large benthic isopod, reaching in length weighing . Amphipods are abundant in soft sediments, eating a range of items, from algae to other animals. The amphipods are highly diverse with more than 600 recognized species found south of the Antarctic Convergence and there are indications that many undescribed species remain. Among these are several "giants", such as the iconic epimeriids that are up to long.

Allobates marchesianus (common name: dull rocket frog) is a species of frog in the family Aromobatidae. It is found in the Amazon Basin in Brazil, Colombia, Ecuador, Peru, and Venezuela. However, this species might represent a cryptic species complex, where at least the populations from Venezuela belong to an undescribed species. Its natural habitats are secondary and old-growth tropical rainforests, where it lives on the forest floor.

Sentinelese is a name provisionally given to the linguistically undescribed language of the Sentinelese of North Sentinel Island in the Andaman and Nicobar Islands, India. Due to the lack of contact between the Sentinelese people and the rest of the world, little is known of their language, or its vitality. The Sentinelese people do not allow outsiders onto the island and are generally hostile towards visitors. Van Driem, G. (2007).

Pristimantis peruvianus is a species of frog in the family Craugastoridae. It is found in the upper Amazon Basin in western Brazil, southern Ecuador, eastern Peru, and southeast Colombia. Records from Bolivia likely refer to an undescribed species, although it is possible that also the "true" Pristimantis peruvianus is to be found there. Its natural habitats are upland cloud forests, flooded lowland forests, and oxbow palm swamp forests.

Paroxysmal Nonkinesigenic Dyskinesia (PNKD) is an episodic movement disorder first described by Mount and Reback in 1940 under the name "Familial paroxysmal choreoathetosis".Mount, L. A.; Reback, S. : Familial paroxysmal choreoathetosis: preliminary report on a hitherto undescribed clinical syndrome. Arch. Neurol. Psychiat. 44: 841-847, 1940. It is a rare hereditary disease that affects various muscular and nervous systems in the body, passing to roughly fifty percent of the offspring.

Pristimantis altamazonicus is a species of frog in the family Craugastoridae. As currently defined, it is known from the Amazonian Colombia, Ecuador, and Peru. Following a study by Ortega-Andrade and colleagues published in 2017, Pristimantis brevicrus (Andersson, 1945), thought to be a synonym of Pristimantis altamazonicus, was resurrected. Furthermore, specimens from Brazil and Bolivia traditionally referred to this species were found to represent other, as yet undescribed species.

Engystomops pustulatus (common name: Guayaquil dwarf frog) is a species of frog in the family Leptodactylidae. It is known with certainty from western Ecuador, whereas the status of Peruvian records is ambiguous as they may refer to an undescribed species or possibly Engystomops puyango. Nevertheless, given that E. pustulatus is now known from Huaquillas in southern Ecuador, near the Peruvian border, it is likely to be found in Peru too.

Other experts maintain the two genera as separate. Canadian paleontologist Phil Currie claims there are as many anatomical differences between Albertosaurus and Gorgosaurus as there are between Daspletosaurus and Tyrannosaurus, which are almost always kept separate. He also notes that undescribed tyrannosaurids discovered in Alaska, New Mexico and elsewhere in North America may help clarify the situation. Gregory S. Paul has suggested that Gorgosaurus libratus is ancestral to Albertosaurus sarcophagus.Paul.

First described in 1776, A. maculata had long been dismissed as invalid. It was rediscovered as part of a study of specimens of the sun parakeet and related species. Specimens of the sulphur-breasted parakeet had previously been dismissed as immature sun parakeets or hybrids. Believing it represented an entirely undescribed species, it was described as A. pintoi (in honour of the Brazilian ornithologist Olivério Pinto) in 2005.

Brazilian ichthyologist Mauro Luís Triques described E. vicentespelaea in a 1996 volume of the scientific journal Revue Française de Aquariologie, from two specimens caught in 1978. He chose the specific epithet vicentespelaea from the São Vicente I cave, the type locality, and speleum, Latin for "cave". Based on color pattern and morphology, it is included in the E. virescens species group with E. virescens, E. trilineata, and a third undescribed species.

It is characterized by the production of conidia within pycnidia. The symptoms include chlorotic spots that turn brown and necrotic. Septoria apiicola can survive on seeds. Several species of passion flower are infected by several species of Septoria, and a fungus, which has been going by the name Septoria passiflorae but which is probably an undescribed species, has been used to control the invasive Passiflora tarminiana in Hawai'i.

41: 65–74 A population discovered in the Apurímac–Cuzco region of southern Peru (more than south of the previous distribution limit) has tentatively been identified as the western mountain coati, but may represent an undescribed taxon.Pacheco, V., R. Cadenillas, E. Salas, C. Tello, and H. Zeballos (2009). Diversidad y endemismo de los mamíferos del Perú/Diversity and endemism of Peruvian mammals. Rev. Peru. Biol. 16(1): 5-32.

Haliclystus sanjuanensis is a species of small (~4 cm) stalked jellyfish found in the Pacific Ocean along the west coast of North America. This species can be found in shallow waters at low tide on soft substrates such as seagrass (Phyllospadix). A variety of colour morphs can be found ranging from yellow- green to red. Haliclystus sanjuanensis remains undescribed officially, despite sequence data establishing it as a distinct taxon.

Ornithopods are common in the Hell Creek Formation, and are known from several species of the ornithopod Thescelosaurus and the hadrosaurids Edmontosaurus, and a possible species of Parasaurolophus. Several pachycephalosaurians have been found in the Hell Creek Formation and in similar formations. Among them are the derived pachycephalosaurids Stygimoloch, Dracorex, Pachycephalosaurus, Sphaerotholus, and an undescribed specimen from North Dakota. The first two might be junior synonyms of Pachycephalosaurus.

Zieria inexpectata was first formally described in 2007 by Marco Duretto and Paul Forster from a specimen collected near Gayndah and the description was published in Austrobaileya. The specific epithet (inexpectata) refers to the unexpected discovery of this species whilst the authors were studying an undescribed species of Boronia on a field trip. The discovery lead to a paper on the zierias of Queensland, including sixteen new species.

These include church inquisitor, consecrated harrier, contemplative, divine oracle, holy liberator, hospitaler, pious templar, sacred exorcist, sacred fist and warpriest (Defenders of the Faith), blighter and geomancer (Masters of the Wild), temple raider of Olidammara (Song and Silence), void disciple (Oriental Adventures), ur-priests (Book of Vile Darkness), stormlord (Faiths and Pantheons), radiant servant of Pelor and shining blade of Heironeous. In addition, there are several previously undescribed prestige classes.

Their small size has caused them to be missed when collecting. Yellow pan trapping and fine-mesh netting in Malaise and aerial sweep nets has resulted in a number of undescribed species from many parts of the world. A high diversity of both genera and species exists for this family in Africa, especially northern and southern portions. About 350 species are known (most in the genus Mythicomyia Coquillett).

Withering analysing thermal waters at Caldas da Rainha Withering was an enthusiastic chemist and geologist. He conducted a series of experiments on Terra Ponderosa, a heavy ore from Cumberland, England. He deduced that it contained a hitherto undescribed element which he was unable to characterise. It was later shown to be barium carbonate and in 1789 the German geologist Abraham Gottlob Werner named the mineral Witherite in his honour.

Restoration of a Saurornitholestes langstoni digging a multituberculate out of a burrow A specimen of Troodon formosus bears a pathological opening. Competing explanations for this pathology include a cyst or bite wound. One hatchling specimen may have suffered from a congenital defect resulting in the front part of its lower jaw being twisted. An undescribed immature dromaeosaurid from Tugrugeen Shireh has been reported with a split belly rib.

"Bayosaurus" is the informal name given to an as yet undescribed genus of dinosaur. The name was coined by paleontologists Rodolfo Coria, Philip J. Currie, and Paulina Carabajal in 2006. It apparently was an abelisauroid from the Turonian Cerro Lisandro Formation of Neuquén, Argentina, around long. The specimen is MCF- PVPH-237, including dorsal and sacral vertebrae, a fragmentary pelvis, and other partial bones, which were discovered in 2000.

"Beelemodon" is the informal name given to an undescribed theropod genus from the Late Jurassic, possibly belonging to a coelurosaur. The fossils include two teeth found in Wyoming, United States. The name appeared in print in 1997, when paleontologist Robert T. Bakker mentioned it in a symposium for the Academy of Natural Sciences.Bakker, R. Raptor family values: Allosaur parents brought great carcasses into their lair to feed their young.

Acer ferrignoi is known from a small group of fossils from a late Miocene fossil site listed as USGS 9737. The site is located near Lolo Pass in the northern Oregon Cascade mountains. The fossils were first studied by paleobotanists Jack A. Wolfe of the United States Geological Survey, Denver office and Toshimasa Tanai of Hokkaido University. They determined that fossils belonged to an undescribed Acer section Eriocarpa species.

"Microdontosaurus" (meaning "tiny-toothed lizard") is the name given to an as yet undescribed genus of sauropod dinosaur from China. It was named from fossils from the Middle Jurassic-age Dapuka Group of Xinjiang. The intended type species is "M. dayensis." As with other informal names created by Zhao in 1985 or 1983, it has not been used since then, and may have been redescribed under another name.

IDP is bound in the cytosolic region of each subunit and trapped by numerous charged residues and five Mg2+ ions. A previously undescribed proton translocation pathway is formed by six core transmembrane helices. Proton pumping can be initialized by PP(i) hydrolysis, and H+ is then transported into the vacuolar lumen through a pathway consisting of Arg 242, Asp 294, Lys 742 and Glu 301. Lin et al.

This species was discovered by Thomas Hall, a sheep musterer on Pitt Island in the Chathams, who collected numerous specimens of undescribed species for Broun. Despite being described from Pitt Island, it has not been seen there since Hall discovered it, probably because its host plant there has been almost wiped out by sheep. It is one of four Hadramphus weevil species, all endemic to New Zealand, specialised, flightless, and rare.

A. phrygiatus and A. rugispinis were both originally described by Achille Valenciennes in 1840 as Arius species, where they have been traditionally placed. They have also been classified in the genus Notarius. Since then, it has been recognized that these two species form a natural, monophyletic grouping and were suggested to represent a new, undescribed genus. The genus Amphiarius was finally erected for these two species in 2007.

In appearance it quite resembles sumatrana, but intermediates between punctata and marica may occur in the area where their ranges come into contact in Thailand. A secondary problem is related to certain Chinese and Nepali populations, by some authorities recognize as the subspecies clarkei and gorkhali, but others consider both as synonyms of caniceps. Additionally, populations in the Chinese provinces of Gansu, Guangxi, Hubei, Hunan and Shaanxi appear to belong to two undescribed taxa.

Labidochromis caeruleus Labidochromis is a genus of cichlid fishes that are endemic to Lake Malawi in East Africa. The genus includes 18 formally described species, and several yet undescribed species. It includes a number of species commonly kept in cichlid aquariums such as L. caeruleus (electric yellow). The species in this genus can easily hybridize, so if kept in an aquarium it is recommended to only have one species from this genus.

Macrotritopus is a poorly known genus of octopuses in the family Octopodidae. As it stands, Macrotritopus contains one valid described species, Macrotritopus defilippi. Two poorly described, unresolved taxa which are known only from planktonic hatchlings have been tentively assigned Macrotritopus equivocus and M. scorpio, as well as a further three undescribed Indo-Pacific species. Macrotritopus was originally described from a single juvenile specimen which was named Macrotritopus equivocus notable for having an elongated third arm.

Eumetopina flavipes, the island sugarcane planthopper, is a species of planthopper present throughout South East Asia. E. flavipes is a vector for Ramu stunt disease, a plant disease which affects sugarcane. Ramu stunt disease is widespread throughout Papua New Guinea, but has not been detected in Australia. Eumetopina is thought to have evolved in Papua New Guinea, where up to four undescribed species have been collected, but many more may be present.

Pterygoplichthyini is a tribe of catfishes (order Siluriformes) of the family Loricariidae. It includes two genera, Pterygoplichthys and the currently undescribed genus referred to as the Hemiancistrus annectens group, This group was earlier misspelled as Pterygoplichthini. Pterygoplichthyines are known from nearly the entire range of loricariids except for the Guyanas and coastal streams in southeastern Brazil. although later work by the same authority, and his co-authors, placed this group among the genus Hypostomus.

Nectomys apicalis, also known as the western Amazonian nectomys,Musser and Carleton, 2005 is a semiaquatic species of rodent in the genus Nectomys of family Cricetidae. It is found east of the Andes in Ecuador, Peru, and Bolivia, east into western Brazil; further to the east, it is replaced by N. rattus. It lives near watercourses in lowland tropical rainforest. Its karyotype has 2n = 38–42, and it probably actually represents several distinct undescribed species.

However, an even earlier specimen now recognized as P. goiasensis had been collected in 1966 near Posse in the northeastern state of Goiás by a group from the New York Botanical Garden. Initially, the specimen had been determined to be a member of the Lentibulariaceae. Peter Taylor and David Philcox later concluded that this represented an undescribed genus of Scrophulariaceae. A description and illustration was completed and set aside for over twenty years.

Acerosodontosaurus is known from a single specimen stored at the Museum National d'Histoire Naturalle in Paris, France. This specimen, MNHN 1908-32-57, was referred to Tangasaurus and stayed undescribed until Phillip J. Currie recognized it as a new genus. He described it as Acerosodontosaurus piveteaui in 1980, a name which roughly translates to "Piveteau's needle- toothed lizard". The specific name references Jean Piveteau, a paleontologist who pioneered the study of Permian reptiles of Madagascar.

Galianora is a genus of Ecuadorian jumping spiders that was first described by Wayne Paul Maddison in 2006. it contains only two species, found only in Ecuador: G. bryicola and G. sacha. The two described species have quite a different body form: G. sacha is elongate and pale, with raptorial front legs, while G. bryicola is compact and brown. An as-yet undescribed species from Venezuela is intermediate in body form and palp.

Isolated and relatively homogeneous habitats such as crater lakes and islands are among the best geographical settings in which to demonstrate sympatric speciation. For example, Nicaragua crater lake cichlid fishes include nine described species and dozens of undescribed species that have evolved by sympatric speciation. Monostroma latissimum, a marine green algae, also shows sympatric speciation in southwest Japanese islands. Although panmictic, the molecular phylogenetics using nuclear introns revealed staggering diversification of population.

Afraflacilla species in Australia include A. grayorum, A. gunbar, A. huntorum, A. milledgei, A. stridulator, A. vestjensi and A. yeni. In Australia they occupy tree trunks in deserts, savanna woodland and in open sclerophyll forests from south west Western Australia to Cape York Queensland, mostly in warmer regions. There are many undescribed Australian species. Afraflacilla grayorum Grays' stridulating jumping spider, found in northern Australian deserts, was named in honour of Michael and Greta Gray.

The long-tailed duck (Clangula hyemalis), commonly known in North America as oldsquaw, is a medium-sized sea duck. It is the only living member of its genus, Clangula. This was formerly used for the goldeneyes, with the long- tailed duck being placed in Harelda, but the latter is the type species of the genus. An undescribed congener is known from the Middle Miocene Sajóvölgyi Formation (Late Badenian, 13–12 Mya) of Mátraszőlős, Hungary.

The blue-fronted fig parrot, also referred to as the blue-browed fig parrot, is a putative undescribed fig parrot said to inhabit the rugged rainforest- covered border ranges of subtropical south-eastern Queensland and north- eastern New South Wales, Australia. It was announced in November 2006 as the discovery of a new species or subspecies. However, the existence of the parrot has not been confirmed and the claimed discovery has been questioned.

As the African species differs from the Asian taxa in a number of important morphological features as well as in habitat, Faden assigned it to a new subgenus Keatingia. The taxonomic boundaries of some species are not completely understood, mainly due to a lack of herbarium specimens. For example, both T. brevipedicellatum and T. glanduliferum are each known from only two collections. A number of undescribed species are also likely to remain.

The other is G. sumatrensis, which was found in a captive Sumatran Rhinoceros in 1884 but has not been observed since. Due to the difficulty of observing these short- lived flies, it is possible that there are other species corresponding to the other species of rhinoceros, but they remain undescribed. It is also possible that several species of Gyrostigma are extinct because rhinoceros populations are tiny owing to their state of endangerment.

Magnapinna sp. C is an undescribed species of bigfin squid known only from a single specimen of 79 mm mantle length (ML) collected in the southern Atlantic Ocean and held in the Natural History Museum. It is characterised by several morphological features: the proximal tentacles are more slender than arm pair IV, pigmentation is contained in the chromatophores, and "white nodules" are absent from the fins and glandular regions of the proximal tentacles. Magnapinna sp.

It is wingless and somewhat laterally compressed, giving it a somewhat flea-like appearance. It has been found in the Auckland Islands and Campbell Island in the New Zealand subantarctic. This or closely related undescribed species have also been found at high altitude above the Paparoa Range and Stewart Island. The generic name is derived from the stem apter- of apteros (Greek for "wingless") and Achalcus, the name of a closely related genus.

The species was first formally described by botanist Ferdinand von Mueller in his paper Definitions of rare or hitherto undescribed Australian Plants, chiefly collected within the boundaries of the colony of Victoria which was published in 1855. Mueller gave it the name Oxylobium alpestre. The species was transferred to the genus Podolobium in 1995. It occurs in alpine heaths and high-altitude woodland in Victoria, New South Wales and the Australian Capital Territory.

Geophagus sp. "orange head", an undescribed species known only from the lower Tapajós basin The Tapajós is one of three major clearwater rivers in the Amazon Basin (the others are Xingu and Tocantins; the latter arguably outside the Amazon).Duncan, W.P.; and Fernandes, M.N. (2010). Physicochemical characterization of the white, black, and clearwater rivers of the Amazon Basin and its implications on the distribution of freshwater stingrays (Chondrichthyes, Potamotrygonidae). PanamJAS 5(3): 454-464.

In the early 20th century, Australian ichthyologist James Douglas Ogilby was identifying fishes to give advice to fisheries, under supervision of James Stevens, the Queensland Inspector of Fisheries. When the question emerged of what was damaging oyster populations in the Wide Bay district in January 1908, Ogilby determined that the organism to cause this damage was a large fish, yet undescribed to science. He described it as Trachinotus anak in a report in 1909.

During his time there, he collected insects extensively on Oahu and also made brief collecting journeys to other islands of the archipelago. "The first resident naturalist to concentrate on insects", he "supplied scientists at the British Museum in London and elsewhere with a steady stream of specimens, refuting the belief that insects were poorly represented in Hawai'i". Among his discoveries were 23 previously undescribed species of carabid beetles of the tribe Platynini.Liebherr & Zimmerman, p. 14.

Twelve threatened and near threatened bird species were recorded. It is estimated that the probable total bird species inventory exceeds 550 species: an exceptional diversity, making the Serranía a global avian "hotspot" and extremely important for bird diversity. 46 species of amphibians (30 species) and reptiles (16 species) were recorded, including four new species for Colombia and several potentially undescribed taxa. Mammals registered include spectacled bear (Tremarctos ornatus) and mountain tapir (Tapirus pinchaque).

Electromyrmex is known from several fossil specimens of adult workers. A worker was first discovered preserved as an inclusion in a transparent chunk of Baltic amber, and additional workers have been identified from Baltic amber found in Lithuania. Workers of an undescribed species labeled as "Electromyrmex sp A" have been found in Bitterfeld amber. Baltic amber is approximately forty six million years old, having been deposited during Lutetian stage of the Middle Eocene.

During this time, he accompanied Harold Manter, an expert on Digenean trematodes of fish, who was on sabbatical from the University of Nebraska, on field trips to Heron Island and Stradbroke Island to help catch fish. He had originally planned to study the ecology of Monogenea trematodes and their hosts, but, finding that so many of his specimens were undescribed, decided to become a taxonomist instead. Young published nine papers from his doctoral research.

Many undescribed species of fungi are suspected in Madagascar. A number of edible mushrooms are consumed in the country, especially from the genera Auricularia, Lepiota, Cantharellus (the chanterelles), and Russula (the brittlegills). Most of the ectomycorrhizal species are found in plantations of introduced eucalyptus and pine, but also in native tapia (Uapaca bojeri) woodlands. The chytrid fungus Batrachochytrium dendrobatidis, responsible for chytridiomycosis, an infectious disease threatening amphibian populations worldwide, was long considered absent from Madagascar.

Nepenthes rigidifolia was discovered by Ch'ien Lee some time before 2001. The species was mentioned as an undescribed taxon in Charles Clarke's 2001 book, Nepenthes of Sumatra and Peninsular Malaysia, under the name "Nepenthes species A". At the time, it was recorded as growing at an elevation of around 1600 m. In 2004, Ch'ien Lee informally named the species N. alpicola and later N. aptera. Cultivated plants were sold under both of these names.

Undescribed Micrarchus species illustrated by Des Helmore Stick insects in New Zealand are found in a range of different environments, from cold high alpine areas to dry coastal bush. There are currently 23 different species described, from 10 genera . The most common species of the stick insect in New Zealand is the smooth stick insect (Clitarchus hookeri) . Following , the New Zealand stick insects are placed into the subfamilies Phasmatinae (tribe: Acanthoxylini) and Pachymorphinae (tribe: Pachymorphinini).

The holotype was discovered in early 1871 in the Bremke dell locality, near the county of Göttingen. The holotype was found in a deposit called the Solling- Bausandstein, which is an outcropping of the upper Middle Buntsandstein in the region of Eichsfeld. After the holotype was uncovered, it was housed in the University of Göttingen . It remained undescribed until 1902, when German paleontologist Friedrich von Huene designated it to the new species Ctenosaurus koeneni.

The Protea Banks Marine Protected Area is a marine conservation area on the continental shelf edge off the South Coast of KwaZulu-Natal in South Africa. Seven species of shark are known to aggregate in this area, including hammerheads, ragged-tooth and giant guitarsharks. Several undescribed species of fish, corals and comb jellies have been observed. The Sardine Run occurs in this area and the new MPA is expected to support a tourism economy.

Subgenus Morula (Oppomorus) formed a separate clade; the authors proposed returning Oppomorus to genus level, containing O. nodulifera, O. funiculata and O. purpureocincta. M. ceylonica, M. granulata, M. marginalba, M. musiva, and an undescribed species formed a distinct clade related to Muricodrupa. The authors proposed resurrecting the genus name Tenguella, for which T. granulata is the type species. They note that these species "have not previously been recognized as a morphologically distinctive group".

The large-scale whiting has been recorded from Japan, the Indonesian Archipelago, New Britain, Solomon Islands and the Philippines A 1980 report from India by Dutt and Sajutha is in error and was the first recording of the then undescribed species, Sillago lutea. The species enters estuaries and may penetrate freshwater rivers, at least as juveniles. Large-scale whiting are only found in relatively shallow water of 0 to 5 m in depth.

Pelvicachromis silviae is a species of cichlid in the genus Pelvicachromis. It is found in the Niger River, in the same region as congeners Pelvicachromis pulcher and Pelvicachromis taeniatus. It was described by Anton Lamboj in 2013. Prior to its formal description it was relatively common in the aquarium fish hobby, denoted as either a subspecies of Pelvicachromis subocellatus or as an undescribed species similar to P. subocelatus, Pelvicachromis sp. aff. subocellatus.

Bostrychus microphthalmus is a species of fish from the family Butidae. It is endemic to Maros karst in the South Sulawesi region of Sulawesi, Indonesia. It was the first documented cave-dwelling fish in Sulawesi, but since then the brotula Diancistrus typhlops has been described from nearby Muna Island, and an additional apparently undescribed eleotrid is known from Sulawesi's Maros karst. The specific name of B. microphthalmus refers to the small eyes of this fish.

Undescribed Early Jurassic heterodontosaurids are also known from the United States and Mexico, respectively. In addition, beginning in the 1970s, a great deal of fossil material was discovered from the Late Jurassic Morrison Formation near Fruita, Colorado in the United States. Described in print in 2009, this material was placed in the genus Fruitadens. Heterodontosaurid teeth lacking a cingulum have also been described from Late Jurassic and Early Cretaceous formations in Spain and Portugal.

Choerophryne variegata is a species of frog in the family Microhylidae. It is endemic to West Papua, Indonesia, and is only known with certainty from its type locality, Digul River. It is assumed that most records from elsewhere refer to other, possibly undescribed species. As the species is only known from one specimen from its vaguely stated type locality, its ecology is essentially unknown, although it is presumed to be a rainforest inhabitant.

The so-called "desert mantella", a likely undescribed species that is closely related to the blue-legged mantella The blue-legged mantella has a snout–to–vent length of . It is quite distinctive with aposematic colours, a warning of the alkaloid toxins in its skin. The back and top of the head are yellow, contrasted by blue legs, and black flanks and sides of the head. The underside is black with blue spots.

Archibald Menzies was the first European naturalist to make collections of verticordias. Menzies sailed on HMS Discovery during the Vancouver Expedition and made his collections in October 1791 near King George Sound, but these specimens would remain undescribed for 35 years. The first formal description of a plant now known as a verticordia was by René Desfontaines in 1826. Desfontaines described a specimen which Robert Brown had collected at Lucky Bay in January 1802.

In 1968, taxonomist Robert Hoffstetter placed undescribed sloth remains into the family Megatheriidae, possibly belonging to the now-defunct subfamily Planopsinae, mainly based on similarities with the ankle bone and femur. Upon species description in 1995, they were moved into the subfamily Nothrotheriinae. In 2004, this was later elevated to family Nothrotheriidae, and the sloths were put into the new subfamily Thalassocninae. In 2017, the sloths were moved back to the family Megatheriidae.

Restoration of a sub- adult individual Gorgosaurus is classified in the theropod subfamily Albertosaurinae within the family Tyrannosauridae. It is most closely related to the slightly younger Albertosaurus. These are the only two definite albertosaurine genera that have been described, although other undescribed species may exist. Appalachiosaurus was described as a basal tyrannosauroid just outside Tyrannosauridae, although American paleontologist Thomas Holtz published a phylogenetic analysis in 2004 which indicated it was an albertosaurine.

Crawford began studying these pests in 1886, investigating the susceptibility of different fruit varieties. He found another related species, hitherto undescribed. Apple scab was an increasingly serious pest of orchards of the Adelaide Hills, but curiously not a problem on the plains. Experimenters, notably Manning of Hobart in 1875, and Sir Robert Ross and Thomas Pugh locally, made successful experiments with iron sulphate sprayed on the tree and applied to the ground.

The name Maylandia, honours the cichlid enthusiast and author about aquaria Hans Joachim Mayland, who died in 2004, was proposed as a subgenus of Pseudotropheus in 1984,Meyer & Foerster (1984) naming the long-known but undescribed "Ice Blue Zebra" as the type species. In 1997 Stauffer et al.Stauffer et al. (1997) described the genus Metriaclima, dismissing the pre- existing Maylandia on the assumption that it lacked a type species and a diagnosis.

Triceratops and other animals of the Hell Creek Formation Ornithischians are abundant in the Scollard Lance, Laramie, Lance, Denver, and Hell Creek Formation. The main groups of ornithischians are ankylosaurians, ornithopods, ceratopsians, and pachycephalosaurians. Three ankylosaurians are known, Ankylosaurus, Denversaurus, and possibly a species of Edmontonia or an undescribed genus. Multiple genera of ceratopsians are known from the formation other than Triceratops, the leptoceratopsid Leptoceratops, and the chasmosaurine ceratopsids Torosaurus, Nedoceratops and Tatankaceratops.

Seemingly independently, the American William James had published a similar work the year before, but unlike James, Lange specifically stated that vasomotor changes are emotions. The theory became known as the James–Lange theory of emotion. In 1886 Lange published "On Periodical Depressions and their Pathogenesis," an exposé on the previously undescribed illness of periodic depressions without mania known today as major depressive disorder. He asserted that the disease was extremely common in his practice.

Fossils of Proailurus lemanensis were first found in Saint-Gerand and later in Quercy. Robert Hunt, while measuring fragmentary fossils from Hasanda-Gol in Mongolia, placed a lower jaw fragment as Proailurus sp., but Peigne placed the fragment in nimravid genus Eofelis instead, which later authors supported, although at least one suggested the fragment could be assigned to Pseudaelurus cuspidatus instead. Several Proailurus-grade fossils have been found in North America, but remain undescribed.

The cicadas ( or ) are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha, along with smaller jumping bugs such as leafhoppers and froghoppers. The superfamily is divided into two families, Tettigarctidae, with two species in Australia, and Cicadidae, with more than 3,000 species described from around the world; many species remain undescribed. Cicadas have prominent eyes set wide apart, short antennae, and membranous front wings.

Despite this deep divergence, they can hybridize among each other, and also with the Japanese giant salamander. One of these clades was identified in 2019 as Andrias sligoi, a species described in 1924 by Edward George Boulenger and later synonymized with A. davidianus, with the study supporting its revival as a distinct taxon. Another as-of-yet undescribed species was also identified that formerly inhabited rivers originating from the Huangshan mountains in eastern China.

Amnirana albolabris is a species of frog in the family Ranidae. It is widely distributed in Sub-Saharan West and Middle Africa. However, the nominal species includes at least one undescribed species west of Benin; the formal taxonomic changes to split the species have not yet been done. Common names white-lipped frog and forest white-lipped frog has been coined for it, whereas Bamileke Plateau frog refers to now-synonymized Amnirana longipes (=Hylarana longipes).

In the western hemisphere, Glomeridans occur in three disparate areas: an eastern, somewhat Appalachian region from Kentucky to northern Florida and Mississippi; a California region from the San Francisco Bay to the Monterey Bay, and a neotropical region from eastern Mexico (Nuevo León) to central Guatemala. Numerous undescribed fossils are known from the Cenomanian aged Burmese amber, which constitue the oldest known records of the order, though the group probably originated much earlier.

No studies have been published to assess the impact of climate change on this species nor on any other described or undescribed species in the Australian Buprestid fauna, which comprises at least 1,600 species. However, given the very limited habitat within its known geographic range generally, rapid climate change (e.g. within 10 – 100 years) to a climate beyond the climate variations this species can consistently withstand would likely be significantly detrimental to its survival.

At the time, the locality was regarded as being of Silurian age, but it is now known to be Early Devonian. It is claimed that an undescribed species, also from Victoria, extends from the Early Devonian back to the Late Silurian. H. parvula from Kazakhstan and H. sinica from China are also of Early Devonian age. It is sometimes suggested that Hedeia and Yarravia are merely different preservations of the same type of plant.

Parachanna is a genus of snakeheads native to freshwater habitats in tropical Africa. Three recognized extant (living) species are in this genus, but a phylogenetic study from 2017 indicates that a fourth, currently undescribed species also exists.Conte-Grand, C., Britz, R., Dahanukar, N., Raghavan, R., Pethi-yagoda, R., Tan, H.H., Hadiaty, R.K., Yaakob, N.S. & Rüber, L. (2017). Barcoding snakeheads (Teleostei, Channidae) re-visited: Discovering greater species diversity and resolving perpetuated taxonomic confusions.

Aware of being an "homme distrait" (distracted man), Selys often affixed names to undescribed species in his collection (nomina nuda). This led to much later nomenclatural confusion. Selys was an inveterate traveller, spending long periods in most European countries and being an honorary member of almost all European entomological societies including the Royal Entomological Society which so honoured him in 1871. He helped to found the Société Entomologique de Belgique in 1856.

The name derives from the Latin aculeatus, which translates as "prickly", indeed has short prominent spikes along the petiole (the leaf stalk). The stems are usually to slightly emergent, with trunk 6 inches in diameter. Emergent leaves are bright orange, and turn dark green with age, somewhat similar to Zamia integrifolia by coincidence. The male cones are solitary, 15–20 cm long and 4–6 cm diameter; the female cones are undescribed.

Glutinoglossum heptaseptatum grows from the earth in damp habitats. The species is known for certain from one location in the Hradec Králové Region of the Czech Republic, near Liberec. The field also contained mosses, Festuca rubra, Agrostis capillaris and Cirsium palustre. Reports of similar specimens in the literature suggest that the species may also exist in Asia, North America and Australia, but the very wide distribution may instead suggest additional as-yet undescribed taxa.

Lenomyrmex hoelldobleri is a species of ant known only from a single specimen found in the stomach of a "devil frog" (Oophaga sylvatica) in Ecuador. Dunn's earth snake (Geophis dunni) is another creature which has only been found in the stomach of another animal, in this case the coral snake (Micrurus nigrocinctus) in 1932, and several other as-yet-undescribed insects were found alongside Lenomyrmex hoelldobleri in the "devil frog"'s stomach.

"Hironosaurus" (meaning "Hirono lizard") is the informal name given to an as-yet undescribed genus of dinosaur from the Late Cretaceous. Found in Hirono, Fukushima, Japan, it was probably a type of hadrosaur, although no subfamily identification has been made. The fossils are quite fragmentary, and consist of teeth and a vertebra, possibly from the tail. Since the fossils have never been fully described in a scientific paper, "Hironosaurus" is considered a nomen nudum.

While when the same test was done on the EILV, the virus showed no cytopathic effect on the vertebrate cell lines. Therefore, evolutionary these results aid in suggesting that EILV lost its capability in infecting vertebrate cells. Thus, EILV appears to be mosquito-specific and represents a previously undescribed complex within the genus Alphavirus. Reverse genetic studies of EILV may help in the discovery of determinants of alphavirus host range which balances disease emergence.

Here, the Aetiocetidae is the sister taxon to Eomysticetus+ Micromysticetus + Diorocetus + Pelocetus + crown Mysticeti. In their sample, Aetiocetus is the second-most basal mysticete; two undescribed museum specimens, ChM, are considered the most basal mysticetes in this phylogeny. In Geisler et al.’s 2011 study entitled “A supermatrix analysis of genomic, morphological, and paleontological data from crown Cetacea”, there is higher resolution of Aetiocetus’ phylogenetic relationship with other mysticetes, as well as more taxa considered.

Eucrenonaspides oinotheke is a species of crustacean in the family Psammaspidae (Order Anaspidacea), endemic to Tasmania, the only species described in the genus Eucrenonaspides. It was described from a spring at 9 Payton Place, Devonport, Tasmania in 1980, making it "the first spring- dwelling syncarid recorded from the Australian region". It is listed as a vulnerable species on the IUCN Red List. A further undescribed species is known from south-western Tasmania.

Nepenthes northiana was first brought to the attention of the scientific community by Marianne North, who painted plants brought to her from the Bau area of Sarawak, Borneo. Harry Veitch, owner of James Veitch & Sons, recognised these as belonging to an as yet undescribed species and sent Charles Curtis to locate a sample and send seeds to the United Kingdom. The species was subsequently named after Marianne North in 1881 by Joseph Dalton Hooker. The type specimen, M.North s.n.

The fish species richness in the Parnaíba River Basin has traditionally been considered impoverished, but this has been disproven by recent surveys, which have recorded about 140 native species (including several that remain undescribed) and about 40% of these are endemic. One of the basin endemics is the freshwater stingray Potamotrygon signata.Moro, G.I; Charvet, P.; and Rosa, R.S. (2012). Insectivory in Potamotrygon signata (Chondrichthyes: Potamotrygonidae), an endemic freshwater stingray from the Parnaíba River basin, northeastern Brazil. Braz.

Elseya branderhorsti (Branderhorst's snapping turtle) is a species of freshwater turtle in the family Chelidae. The species is endemic to southern New Guinea, in West Papua Indonesia and Western Province of Papua New Guinea. Until recently it has been a confusing species due to its lost holotype and its sympatry with another, undescribed, species. E. branderhorsti is currently listed as Vulnerable on the IUCN RedList in part due to its vulnerability to the Asian turtle trade.

There are two described mechanisms of gametophytic self-incompatibility that have been shown to occur in four families of dicots (RNase and S-glycoprotein) but none have been found in monocots. However, there is evidence that orchids have an alternative undescribed mechanism of gametophytic self-incompatibility. Homomorphic sporophytic self-incompatibility has not yet been discovered in monocots. In this form compatibility is determined by the genotype of the anther from which the pollen grain was created.

Aesculus parviflora is grown as an ornamental plant in gardens, where its August flowering attracts butterflies. The naturalist, explorer and plant collector William Bartram first noted this undescribed shrub on his travels through Carolina, Georgia and Florida in 1773–78.Noted by Alice M. Coats, Garden Shrubs and Their Histories (1964) 1992, s.v. "Aesculus"; Bartram's botanizing explorations were recorded in his Travels through North and South Carolina, Georgia, East and West Florida, the Cherokee Country, etc.

N. australis has palp morphology and fringing on its first pair of legs very similar to that seen in N. nojimai Ikeda 1995, from Japan. N. taylori is most similar in morphology to N. sumatranus from Indonesia and N. kovblyuki from the Crimea and elsewhere. The genus is common and widespread in litter throughout Australia, from the highlands of Tasmania through the hot, dry inland to the wet tropics and includes many undescribed species.Richardson, B. J. (2013).

The center of its diversity appears to be New Guinea where 51 or more species can be found in a single locality. Many of them are very similar to each other, but male genital characters and DNA barcoding allow a safe identification. In January 2016, a paper was published that revised the Australian species within this genus. That paper described 24 new species and indicated the potential for more research into undescribed Australian species within this genus.

Studying pink-pored boletes from China, mycologists Yan Chun Li, Bang Feng, and Zhu L. Yang showed using molecular phylogenetic analysis that several species–some still undescribed–were part of a unique genetic lineage distinct from other Boletaceae genera. Two species were transferred from other genera—Zangia chlorinosma from Tylopilus, and the type species, Zangia roseola, previously considered Boletus or Tylopilus. Four species were described as new. The sister taxon to the genus is the truffle- like Royoungia.

Two extinct undescribed species of Nesophontes are known from several cave deposits on the Cayman Islands, a British archipelago south of Cuba. The two are similar in morphology, but the species from Grand Cayman is larger than the one from Cayman Brac. They are closely related to each other and to the Cuban–Hispaniolan species N. micrus. The oldest record is from the latest Pleistocene, but they probably arrived there earlier in the Pleistocene, if not in the Pliocene.

In fact, one of the traits, a posterodorsally inclined ridge on the lateral side of the ilium, was found on the undescribed left ilium of the holotype of Eotyrannus. This leaves only a single autapomorphy of Stokesosaurus which is not present in Juratyrant or other tyrannosauroids: a swollen rim around the articular surface of the pubic peduncle. The holotype ilium is long, indicating a small individual. Madsen in 1974 estimated that the adult body length was about .

Nutrients and growth factors diffusing from the ambient soil into each culture cell through the membranes nurture growth of the bacterium into a colony that is then self- sustaining in vitro. This arrangement allows growth of only one species in some of the cells. Tests for antibacterial activity against Staphylococcus aureus highlighted a previously undescribed bacterium which was named Eleftheria terrae. It was found to be producing a new antibiotic compound that the researchers named teixobactin.

On the island are about 31 species of birds, an undescribed worm from the family Amphisbaenidae. The climate of Southern Brazil is humid, with hot summers and rainfall all throughout the year. The rainfall is reduced in winter seasons. The Moleques do Sul guinea pigs are found in 6.34 ha area covered with herbaceous vegetation that serves as a stable food source, Paspalum vaginatum and Stenotraphrum secundatum, while it only amounts to 0.77 ha of land.

This genus has a strictly American distribution, inhabiting in the Nearctic and Neotropical regions and containing 60 species, several undescribed. Despite being considered by many ant collectors as "road side weeds", several species of Dorymyrmex shown a high degree of endemicity, specialized habitat preferences, and varied population structure. Some species may serve as potential agents of biological control of annual crop pests. Species of Dorymyrmex nest preferentially in dry or disturbed habitats, generally in soil without vegetation cover.

Montipora corals are preyed upon by corallivorous fish, such as butterflyfish. Montipora corals are known to host endo- and ectoparasites such as Allopodion mirum and Xarifia extensa. A currently undescribed species of nudibranch in the genus Phestilla has also been reported in the scientific and aquarium hobbyist literature to feed on the genus . Montipora corals are susceptible to the same stresses as other Scleractinian corals, such as anthropogenic pollution, sediment, algal growth, and other competitive organisms.

If Yutyrannus did prey on sauropods, it would have been one of two predatory animals known from the Yixian formation capable of doing so, the other being an as-of-yet undescribed large theropod known from a tooth embedded in the rib of a Dongbeititan.Xing L., Bell, P.R., Currie, P.J., Shibata M., Tseng K. & Dong Z. (2012). "A sauropod rib with an embedded theropod tooth: direct evidence for feeding behaviour in the Jehol group, China." Lethaia, (advance online publication). .

The fictional writer and narrator of the chronicle is old Johannes Wacholder. He lives in a small attic room observing and chronicling the happenings in the narrow street of the novel's title. Sparrow Lane is located in Berlin, but the city itself is largely undescribed, with the narrator giving his attention to the lives of the street's inhabitants. Such inhabitants included his childhood friend, the painter Franz Ralff, whose daughter Elise is adopted by Wachholder after her parents' deaths.

In the summer of 1991, highway workers digging for a construction project near Smyrna made a major Miocene fossil deposit. Although most of its fossils were of marine life, researchers have regarded its mammal remains as the best discovered north of Florida in the eastern United States. Excavators dug 50 feet into the sediment to uncover both invertebrate and vertebrate remains. Invertebrates included more than a 100 kinds of marine mollusks, roughly a quarter of which were previously undescribed.

Liparis marmoratus Liparis catharus Liparis fabricii The Liparidae, commonly known as snailfish or sea snails, are a family of scorpaeniform marine fishes. Widely distributed from the Arctic to Antarctic Oceans, including the oceans in between, the snailfish family contains more than 30 genera and about 410 described species, but there are also many undescribed species. They are closely related to the sculpins (family Cottidae) and lumpfish (family Cyclopteridae). In the past, snailfish were sometimes included within the latter family.

Aphonopelma pallidum is a tarantula of the family Theraphosidae found in Mexico. Commonly called the rose-grey, or Mexican rose, it is not available in the pet-trade. During the late 1990s and early 2000s, and undescribed species of Brachypelma was often traded under the name pallidum, but was since formally described as Brachypelma verdezi by Schmidt 2003. The adult male has brown legs, and the carapace a dull rose grey, while the female is unknown.

Given the present instabilities in Burma, one choice for scholars is to study the Shan people and their language in Thailand, where estimates of Shan refugees run as high as two million, and Mae Hong Son Province is home to a Shan majority. The major source for information about the Shan language in English is Dunwoody Press's Shan for English Speakers. They also publish a Shan-English dictionary. Aside from this, the language is almost completely undescribed in English.

N. electra can be identified from the extinct halictid genus Oligochlora by differences in the mesoscutum and carinate pronotal ridge. Although similar to the associated Dominican amber species Eickwortapis dominicana the mesoscutum is again different between the two species. The modern Greater Antilles do not have any native species of Neocorynura. The closest living species is an undescribed species which is found on St. Vincent and Trinidad, known from specimens in the National Museum of Natural History.

Head view of a Thaumatomyrmex mandibularis worker, showing its characteristic pitchfork- shaped mandibles The genus was established by Mayr in 1877 to house the single species Thaumatomyrmex mutilatus, discovered in Brazil. Since its inception, the genus has been placed in various tribes: Ectatommini, Ponerini, Cylindromyrmicini, and its own tribe, Thaumatomyrmecini. Molecular phylogeny by Schmidt & Shattuck (2014) confirmed that the genus is nested within Ponerini. Twelve species has been described, and a few undescribed taxa are known.

Following graduation, James continued to work on hummingbirds with Zusi. When his grant ran out, she accepted a position helping Storrs Olson identify fossil birds from the Hawaiian Islands. The study of Hawaii's fossil birds, of which there were an abundance of undescribed species, became a long-term collaborative research program for James and Olson. (They were married in 1981 but later divorced.) From the fossil record, they identified about 60 bird species of Hawaii that had become extinct.

Before 2004, the genus Microsynodontis was believed to contain only four species, Microsynodontis batesii, M. christyi, M. lamberti, and M. polli. However, when examining previously collected specimens from the lower Guinea region that had been identified as M. batesii, Dr. Ng discovered that the specimens actually consisted of nine distinct species, eight of them previously undescribed. He published the descriptions of the new species in 2004. M. armatus is one of the new species that he described.

Hingol National Park contains a variety of topographical features and habitats, varying from arid subtropical forest in the north to arid montane in the west. Large areas of the park are covered with drift sand and can be classified as coastal semi desert. The park includes the estuary of the Hungol River which supports a significant diversity of bird and fish species. Some 250 plant species were recorded in the initial surveys including 7 yet undescribed species.

The fossils recovered from a marlstone remained undescribed until 1999 and palaeontologists referred to the genus simply as "rauisuchid" or "Kupferzellia". In 1999, palaeontologist David J. Gower described the holotype (SMNS 52970) from the 1977 excavation, which is the largest specimen of the genus, comprised by incomplete skull and postcranial material. Anatomy of the braincase (SMNS 80260) was made three years later, shedding light on the evolutionary relationships of the poorly known group of Rauisuchia.Gower (2002), p. 49.

Kinixys tortoises play host to a number of ectoparasites (external) and endoparasites (internal) A survey (by Alan Probert & Clive Humphreys) of mixed captive K. spekii and K. belliana (mostly K. spekii) in Zimbabwe showed that ticks (Arachnida) and roundworms (Nematoda) of genera Angusticium, Atractis and Tachygontria infect these tortoises. This has been reported by others as well. However, some of the tiny roundworms (photographed under SEM) are very likely new species and as yet remain undescribed.

The spotfin goby cichlid (Tanganicodus irsacae) is an African species of cichlid endemic to Lake Tanganyika where it is only known from the northern end of the lake. They live amongst pebbles in the surf-zone. This species can reach a length of TL. This species can also be found in the aquarium trade. Although presently considered the only species in the genus, another undescribed species is known from the Lukuga River (Lake Tanganyika's outflow river).

Phlyctimantis boulengeri is a species of frog in the family Hyperoliidae. Its distribution area consists of three disjunct areas: western one in Ivory Coast, southeastern Guinea, Liberia, and southern Ghana, and another one in southeastern Nigeria, western Cameroon, and Gabon, and finally, the Bioko island (Equatorial Guinea). The record from Gabon may refer to Phlyctimantis leonardi, and the western populations might belong to an undescribed species. It occurs in secondary forests, forest clearings, and farm bush.

Novopsocus is a genus in the Pseudocaeciliidae family, with, until 2008, one described species endemic to New Guinea. It was later found that the specimens of two different species (one of which undescribed) had been mixed, and an individual of a third species was found. The genus is characterised by a flat head with a sharp vertex, narrow, strap-like wings, and antennae with a broad, flattened first flagellar segment in the males of two species.

Part of Templeton's Mollusca collection was described as comprising several new and rare species hitherto undescribed. Amongst others are new species of each of these genera: Achatina, Helix, Neritina, Ampullaria, Valvata, Planorbis and Melania. Robert Templeton sent back to the Belfast Museum specimens of the Ceylonese pearl mussel showing growth stages of the mussels from the famous pearl fisheries of Ceylon. He also described two species of land-slug (Vaginula maculata and Parfnacella tennenti) from Ceylon.

The taxon was also listed as an undescribed species, "Nepenthes sp. B", in Charles Clarke's Nepenthes of Borneo (1997) and Hugo Steiner's Borneo: Its Mountains and Lowlands with their Pitcher Plants (2002). In "Nepenthes of Gunung Murud", an article published in a 1996 issue of the Carnivorous Plant Newsletter, John De Witte describes a hybrid "most probably between N. veitchii and N. stenophylla or N. fusca",De Witte, J. 1996. Carnivorous Plant Newsletter 25(2): 41–45.

The hoopoe starling probably nested in tree cavities. Many other endemic species on Réunion became extinct after the arrival of humans and the resulting disruption of the island's ecosystem. The Hoopoe starling lived with other now-extinct birds, such as the Réunion ibis, the Mascarene parrot, the Réunion parakeet, the Réunion swamphen, the Réunion owl, the Réunion night heron, and the Réunion pink pigeon. Extinct Réunion reptiles include the Réunion giant tortoise and an undescribed Leiolopisma skink.

The western bearded orchid grows in shrubby woodland and forest, often in thick Casuarina leaf litter and often in small clumps. It occurs between Bindoon and Albany and is common in the Darling Range near Perth. Its range includes the Avon Wheatbelt, Esperance Plains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren biogeographic regions. There are twelve undescribed species of Pterostylis in Western Australia and the range of this species may be redefined when those descriptions are published.

Twenty six days after an undescribed biological disaster, two survivors thereof are forced to live in cumbersome protective biohazard suits and scavenge for food, water and fuel in a desolate dead land. The two follow the incomprehensible sounds of the radio in search of fellow survivors. They stop for supplies at a farm house. One of the characters' suits is accidentally ripped, and when he is tested positively for poisoning he decides to remove his suit.

Common teeth previously referred to Dromaeosaurus and Saurornitholestes later were considered to be Acheroraptor. The tyrannosaurids from the formation are Nanotyrannus and Tyrannosaurus, although the former might be a junior synonym of the latter. Among ornithomimids are the genera Struthiomimus as well as Ornithomimus; an undescribed animal named "Orcomimus" could be from the formation. Troodontids are only represented by Pectinodon and Paronychodon in the Hell Creek Formation; with a possible species of Troodon from the Lance Formation.

The floury baker is distinguished from a similar undescribed species A. curvicosta (the little floury baker) by the structure of the male genitalia and an audibly distinct call. Members of Aleeta and Tryella are easily distinguished from other Australian cicadas as they lack tymbal covers, while the costal margin of their forewings gets larger toward the point where the wing is attached to the body. In these genera it is clearly wider than the costal vein.

It is possible that all these Chinese populations are part of O. sinensis, but the Laos specimens are relatively large, similar to O. latipes rather than the tiny O. sinensis. The east Korean population is part of a clade with O. sakaizumii and O. latipes. Based on morphology it is closer to O. sakaizumii than O. latipes, but it may be an undescribed species. O. latipes has been introduced to Hokkaido in northern Japan (where ricefish are not native).

Compared to other major oceans, there are few fish species in few families in the Southern Ocean. The most species-rich family are the snailfish (Liparidae), followed by the cod icefish (Nototheniidae) and eelpouts (Zoarcidae). Together the snailfish, eelpouts and notothenioids (which includes cod icefish and several other families) account for almost of the more than 320 described fish species in the Southern Ocean. Tens of undescribed species also occur in the region, especially among the snailfish.

The spotted wood quail (Odontophorus guttatus) is a small ground-dwelling bird in the New World quail family. It is a resident breeder in the mountains of Central America from southern Mexico to western Panama. It occurs in highlands from 1000 m or higher up to the timberline, usually in dense understory thickets or bamboos. The nest, as with several other wood-quails remains undescribed, but the eggs are known to be creamy-white with brown spots.

Sequence preferences and binding affinities are characterized based on successful binding interactions between bait molecules and transcription factors. While many unique transcription factor- DNA binding interactions have been characterized using these methods, it is estimated that this described fraction represents fewer than 50% of the transcription factors present in humans. The development of SMiLE-seq technology has provided an attractive alternative method with the potential to facilitate identification and characterization of previously undescribed transcription factor-DNA binding interactions.

Coid, Simone Ullrich and Constantinos Kallis.

The number of animal species listed in this category totals 14033 (which includes several undescribed species such as a frog from the genus Philautus). There are also 101 animal subspecies listed and 1500 plant taxa (1410 species, 55 subspecies, and 35 varieties). No fungi or protista have the classification, though only four species in those kingdoms have been evaluated by the IUCN. Humans qualify for this category, and in 2008 were formally assessed as such by the IUCN.

Megalyroidea is a small hymenopteran superfamily that includes a single family, Megalyridae, with eight extant genera (plus around a dozen extinct ones) and 49 described species. Modern megalyrids are found primarily in the southern hemisphere, though fossils have only been found in the northern hemisphere. The most abundant and species-rich megalyrid fauna is in Australia. Another peak of diversity appears to be in the relict forests of Madagascar, but most of these species are still undescribed.

Cambridge: Cambridge University Press. pp. 272–273 In the 1839 publication of his Journal and Remarks, Darwin said "This fox, more curious or more scientific, but less wise, than the generality of his brethren, is now mounted in the museum of the Zoological Society." He said it was "an undescribed species",Darwin, C. R. 1839. Narrative of the surveying voyages of His Majesty's Ships Adventure and Beagle between the years 1826 and 1836, Journal and Remarks 1832–1836.

In 1963, P. leopoldi was described by J. P. Gosse. Undescribed species may still exist in the Amazon Basin. New species of fish are discovered with increasing frequency, and, like P. scalare and P. leopoldi, the differences may be subtle. Scientific notations describe the P. leopoldi as having 29-35 scales in a lateral row and straight predorsal contour, whereas, P. scalare is described as having 35-45 scales in a lateral row and a notched predorsal contour.

Luciocephalus aura, sometimes called the green-spotted pikehead or peppermint pikehead, is a species of freshwater ray-finned fish from the subfamily Luciocephalinae of the gourami family Osphronemidae. It is endemic to Sumatra where it has been recorded from the middle Batang Hari River and from the middle Musi River drainage. An undescribed similar taxon has been seen in central Kalimantan and this is possibly a third species in the genus Luciocephalus. On Sumatra Luciocephalus aura and l.

The Luzon montane forest mouse (Apomys datae) is a species of rodent in the family Muridae, from the genus Apomys. It occurs only in the Philippines, where it has been found on the large northern island Luzon (in the Cordillera Central and on the coast of Ilocos Norte). It is most closely related to the large Mindoro forest mouse, which occurs on Mindoro. There may be another related species in the Sierra Madre, but this species is yet undescribed.

The jugal is triradiate and the anterior process of the jugal forms the posteroventral corner of the antorbital fossa and surpasses anteriorly the base of the lacrimal, a feature seen in basal thyreophorans and stegosaurs. The dorsal process of the jugal is proportionally long. The quadratojugal is very broad and the premaxilla is incompletely preserved while the post-cranial material is as-yet-undescribed at present. The dentition is heterodont, with six premaxillary teeth and thirty maxillary teeth.

Ayscough's assiduous catalogue of undescribed manuscripts in the British Museum began in April 1780 and was published in 1782 by leave of the trustees, but as a private venture by the compiler. The plan of the book was original and its publication reflects credit on the enterprise of Ayscough, who claims that no work of like extent was ever completed in so short a time.Ayscough, A Catalogue of the MSS. preserved in the British Museum, Preface, p. x.

Kunzea peduncularis was first formally described in 1855 by Ferdinand von Mueller from a specimens found "at the foot of the Australian Alps on the banks of rivers and rivulets". The description was published in his book Definitions of rare or hitherto undescribed Australian plants. The specific epithet (peduncularis) is derived from the Latin word pedunculus meaning "small, slender stalk". This kunzea was formerly included in Kunzea ericoides but that species is now regarded as a New Zealand endemic.

"Yibinosaurus" (meaning "Yibin lizard") is the informal name given to an as yet undescribed genus of herbivorous dinosaur from the Early Jurassic. It was a sauropod which lived in what is now Sichuan, China. The suggested "type species", "Yibinosaurus zhoui", has not been formally described yet, but the formal publication is forthcoming, from Chinese paleontologist Ouyang Hui. "Yibinosaurus" was only briefly mentioned in the Chongqing Natural History Museum guidebook (2001) and is thus a nomen nudum.

"Hanwulosaurus" is the informal name given to an as- yet undescribed genus of dinosaur from the Late Cretaceous. It was an ankylosaur around long, which is long for an ankylosaur. Its fossils were found in Inner Mongolia, China. Much of a skeleton, including a complete skull, vertebrae, ribs, a scapula, an ulna, femorae, bones from the shin, and armor, was discovered; this may be the most complete ankylosaurian skeleton yet found in Asia, according to early reports.

"Oshanosaurus" (meaning "Oshan lizard") is the informal name given to an as yet undescribed genus of sauropod dinosaur from the Early Jurassic period of Yunnan, China. Its fossils were found in the Lower Lufeng Series. The intended "type species", "Oshanosaurus youngi", was coined by Zhao in 1985. It has sometimes been associated with heterodontosaurids, which appears to be due to the juxtaposition of a species of Dianchungosaurus (formerly thought to be a heterodontosaurid) in the text of Zhao (1985).

Typhlops hectus (common names: Tiburon Peninsula blind snake, Thomas's worm snake ) is a species of snake in the family Typhlopidae. It is endemic to southwestern Haiti and is known from the Tiburon Peninsula and the island of Grand Cayemite, with an isolated record from Gonâve Island. Specimens of uncertain status are known further northeast, in an area extending into the Dominican Republic; whether these belong to Typhlops hectus or an undescribed species is pending further investigations.

The wood-moth (Aenetus splendens) makes a thick bag-like structure around a branch where it breeds. The beetle species Maecolaspis favosa attacks the leaves in Florida. Eucalyptus robusta plantations in Madagascar are host to prolific numbers of mushrooms, some of which are edible and widely consumed. Two species of the genus Russula – Russula prolifica and R. madecassense – and several as yet undescribed species of chanterelle of the genus Cantharellus are sold in markets and eaten.

In Madagascar, Azendohsaurus co-existed with the hyperodapedontine rhynchosaur Isalorhynchus, the herbivorous traversodontid cynodonts Dadadon and Menadon, and the predatory chiniquodontid cynodont Chiniquodon kalanoro, as well as an undescribed kannemeyeriiform dicynodont, a sphenodontian reptile, a procolophonid parareptile, the diminutive lagerpetid Kongonaphon, various other undescribed dinosauromorphs, and an "enigmatic archosaur" of uncertain classification. The faunal composition of the Isalo II is believed to represent a Middle Triassic Ladinian aged assemblage, existing prior to the appearance of dinosaurs and associated Late Triassic faunas, particularly aetosaurs and phytosaurs that are absent from the formation, and also inferred from the dominance of traversodonts in the fauna. However, this age assessment remains uncertain, and the formation is possibly from the younger early Late Triassic during the Carnian, as has been proposed for the T5 member of the Argana Formation. Fossils of A. madagaskarensis have been exclusively recovered from a deposit of fine grained red mudstone, while other fossil bearing localities in the formation consist of medium grained channel sands, possibly reflecting a habitat preference in the ecosystem distinct from other animals or unique behavioural trait.

Entomology became an interest after he first started collecting insects in Futak. He built up a vast collection of specimens and books and while he described numerous species, many of the species he collected were undescribed. Towards the end of his life he had six cabinets with sixty drawers reaching from floor to ceiling and his library of 7000 books occupied a separate room. His collection included more than 100,000 Longhorn beetles of nearly 3000 genera and 1500 species from around the world.

During his stay in Amsterdam, Steno discovered a previously undescribed structure, the "ductus stenonianus" (the duct of the parotid salivary gland) in sheep, dog and rabbit heads. A dispute with Blasius over credit for the discovery arose, but Steno's name remained associated with this structure known today as the Stensen's duct. In Leiden, Steno studied the boiled heart of a cow, and determined that it was an ordinary muscle and not the center of warmth as Galenus and Descartes believed.Kooijmans (2007), p. 45.

The South African pouched mouse or southern African pouched mouse (Saccostomus campestris) is a species of rodent in the family Nesomyidae, which is viewed as actually representing a complex of at least three undescribed species. It is found in southern Africa in Angola, Botswana, DR Congo, Malawi, Mozambique, Namibia, South Africa, Eswatini, Tanzania, Zambia and Zimbabwe. This species occurs in savanna woodland, as well as various other habitats, at elevations from 50 to 2000 m. It is present in arid regions of Namibia.

President Chester A. Arthur hired the Washington, D.C., firm of W. B. Moses & Son to redecorate much of the White House in 1881, including the East Room. Moses & Son added new window curtains and drapes, and a suite of ebony furniture carved in a Japanese style. This suite included sofas, arm chairs, side chairs, and corner chairs. Arthur then auctioned off an immense quantity of older White House furnishings in April 1882, including some amount of undescribed older furniture from the East Room.

Taunayia bifasciata is a species of three-barbeled catfish endemic to Brazil where it is found in the Upper Paraíba do Sul and Tietê River basins. This species grows to a length of SL.

Some of the first dendroolithid eggs—which are attributed to therizinosaurs—were reported from the Bayan Shireh and Nanchao formations on the same year, 1997. These consisted of several egg clutches (a group) with an average composition of 7 or more eggs. In addition, the Bayan Shireh Formation has produced fully grown, specific therizinosaurid taxa, such as Erlikosaurus and Segnosaurus. The egg nests from the Nanchao Formation remained undescribed for several years, only being briefly examined but identified to contain fossilized embryos.

Species in this genus, as well as those in several other oreochromine and tilapiine genera, share the common name "tilapia" and historically most were included in the genus Tilapia. Oreochromis contains more than 30 species, and several undescribed forms exist. Judging from mtDNA sequence analysis, several clades seem to exist. Research is hampered because hybridization runs rampant in these fishes, which confounds mtDNA data (Wami tilapia is an example), and the fast speed of evolution makes choice of appropriate nuclear DNA sequences difficult.

Annual Review of Ecology and Systematics 31: 163–196. doi: 10.1146/annurev.ecolsys.31.1.163. The actual number is labelled with some uncertainty because of the many undescribed species and the extreme variation among some species, making the task of delimiting them very complex. Except for four species (Astatotilapia calliptera, Coptodon rendalli, Oreochromis shiranus and Serranochromis robustus), all cichlids in the lake are endemic to the Malawi system, which also includes nearby smaller Lake Malombe and the upper Shire River.Oliver, M.K. (12 April 2015).

Most Malawi cichlids are found in relatively shallow coastal waters, but Diplotaxodon has been recorded down to depths of and several (especially Diplotaxodon, Rhamphochromis and Copadichromis quadrimaculatus) are known from pelagic waters. The cichlids of the lake are divided into two groups and the vast majority of the species are haplochromines. The sister species to the Malawi haplochromines is Astatotilapia sp. Ruaha (a currently undescribed species from Great Ruaha River), and these two separated between 2.13 and 6.76 million years ago (mya).

Ovulating and gravid females are rarely ever caught, suggesting that during this period, they may stop feeding or segregate themselves from others of their species. Potential predators of the night shark include larger sharks. Known parasites include the copepods Kroyeria caseyi, which attach to the gills, Pandarus bicolor and P. smithii, which infest the skin, and the tapeworms Heteronybelinia yamagutii, H. nipponica and Progrillotia dollfusi, which are found in the spiral valve intestine. Another parasite is an undescribed isopod similar to Aega webbii.

By 1991 Faden had recognised the genus as distinct and added yet another species to it, this time T. philippense. He and J. Cowley published a sixth species in 1996, T. pumilum, which is endemic to Borneo. Two years later Faden recognised a seventh undescribed species from Vietnam and also commented on an African plant that could be an eighth species. In 2007 both of these were described with the Vietnamese species being named T. brevipedicellatum and the African species T. africanum.

The heaviest mature moths have been cited in the giant carpenter moth (Xyleutes boisduvali) of Australia, which has weighed up to although the species does not surpass in wingspan. ;Mantises (Mantodea) :The largest species of this order is Toxodera denticulata from Java, which has been measured up to in overall length.Live Pet Mantis Hobby. Bugsincyberspace.com However, an undescribed species from the Cameroon jungle is allegedly much larger than any other mantis and may rival the larger stick insects for the longest living insect.

Life restoration Hesperonychus is known from one partial pelvic girdle, holotype specimen UALVP 48778, collected by Dr. Elizabeth Nicholls in Dinosaur Provincial Park in 1982. The fossil remained undescribed, however, until Nick Longrich and Phil Currie published on it in 2009. A number of very small toe bones, including "sickle claws", in the collection of the Royal Tyrrell Museum may also belong to Hesperonychus. The gracile appearance of these toe bones makes it unlikely that they belonged to a member of Eudromaeosauria.

They are highly active feeders, seldom pausing except when at berries. Most species feed in the lower and middle levels of the forest, although records suggest that the obscure berrypecker will enter the canopy to forage. The male black berrypecker will also enter the canopy, while the female will remain lower down in the forest, suggesting some level of sexual segregation of feeding niches. The breeding of some species is entirely undescribed, and little is known about the breeding in most species.

The species in these deepest records remain undescribed, but it has been referred to as the "ethereal snailfish". The deepest-living described species is Pseudoliparis swirei, also of the Mariana Trench, which has been recorded to . In general, snailfish (notably genera Notoliparis and Pseudoliparis) are the most common and dominant fish family in the hadal zone. There are indications that the larvae of at least some hadal snailfish species spend time in open water at relatively shallow depths, less than .

There are 98 described genera of Gracillariidae (see below). A complete checklist is available of all currently recognised species (de Prins and de Prins 2005). There are many undescribed species in the tropics but there is also an online catalogue of Afrotropical described species ; the South African fauna is quite well known. Although Japanese and Russian authors have recognised additional subfamilies (de Prins and de Prins, 2005), there are three currently recognised subfamilies, Phyllocnistinae of which is likely to be basal.

Many ostracods, especially the Podocopida, are also found in fresh water, and terrestrial species of Mesocypris are known from humid forest soils of South Africa, Australia and New Zealand. They have a wide range of diets, and the group includes carnivores, herbivores, scavengers and filter feeders. As of 2008, around 2000 species and 200 genera of nonmarine ostracods are found. However, a large portion of diversity is still undescribed, indicated by undocumented diversity hotspots of temporary habitats in Africa and Australia.

The Paralichthyidae has long been indicated to be paraphyletic, with the formal description of Cyclopsettidae in 2019 resulting in the split of this family as well. The taxonomy of some groups is in need of a review, as the last monograph covering the entire order was John Roxborough Norman's Monograph of the Flatfishes published in 1934. In particular, Tephrinectes sinensis may represent a family-level lineage and requires further evaluation e.g.. New species are described with some regularity and undescribed species likely remain.

The agaricid Pavona gigantea was rare, but it developed some large colonies with over one meter of height, especially on rocky zones and at depths from three to five meters. The undescribed species has no branches but develops colonies with completely flat upper surfaces. The colonies are developed in layers with each physically separate from the rest. There is evidence off a massive die-off of coral and recolonization, but it is not known what caused the coral to die.

A subspecies of the black-rumped flameback woodpecker (Dinopium benghalense tehminae) was named after his wife, Tehmina, by Whistler and Kinnear. Salim Ali's swift (Apus salimalii) originally described as a population of Apus pacificus was recognised as a full species in 2011 while Zoothera salimalii, an undescribed population within the Zoothera mollissima complex, was named after him in 2016. On his 100th birth Anniversary (12 November 1996) Postal Department of Government of India released a set of two postal stamps.

Xu, Pittman et al. (2015) reject this synonymy by responding to the counterarguments proposed using new and existing details of Linheraptor's anatomy. Tsaagan represents the only dromaeosaurid remains (other than isolated teeth) known from the Ukhaa Tolgod region, though another dromaeosaurid, Velociraptor, is known from the same formation. Animals that may have shared the same habitat with Tsaagan include Protoceratops, Shuvuuia, the small mammal Zalambdalestes, the multituberculate mammal Kryptobaatar, as well as several lizards and two yet-undescribed species of troodontid and dromaeosaurid.

Trigona fuscipennis is under the order of Hymenoptera, along with ants, bees, and wasps. It is also part of the Apidae family which encompasses bumble bees, euglossines, honey bees, and stingless bees, and falls in the genus Trigona, which is specific for stingless bees. The genus Trigona is the largest and most diverse group of stingless bees, with over 80 nominal species and about 28 undescribed species. Bees within this genus are notable for their complex communication styles and diverse nest architecture.

In Central and northern Europe existed the lineage of C. etruscus that gave rise to C. mosbachensis. In 2016, a study looked at previously- undescribed specimens of C. arnensis from the Poggio Rosso site located in the northeastern Upper Valdarno and dated 1.9-1.8 million years ago. There was little deformation in these fossils which allowed a more defined assessment of the morphology of the species. The study found that the phylogenetic position of the Arno River dog is not resolved.

It grows to in standard length, but may possibly reach . Its color ranges from medium-brown to near-black (especially those from the Madeira, Branco and Xingu rivers are dark), and the underparts often have a vermiculated pattern. Some of the variants are commonly considered as separate, undescribed species in the aquarium trade (e.g., L193 from the Orinoco basin and L407 from the Branco basin; in the L-number system), but there is extensive overlap in the morphometrics of the different populations.

Realizing that many Tasmanian Entolomataceae species were undescribed, they and their collaborators published a series of papers documenting the new fungi. Within the genus Entoloma, the fungus is classified in the subgenus Leptonia, section Cyanula because of its overall habit, clampless hyphae, and abundant granules of pigment. Noordeloos and Gates place it in the stirps (a grouping of related species within a genus) Austroprunicolor, characterized by mushrooms with a violaceous pink or blue cap that contrasts with a pallid, whitish, polished stipe.

A 2009 expedition by an international team of scientists and a television crew from the BBC Natural History Unit filming Lost Land of the Volcano, a BBC wildlife documentary, discovered more than 40 previously undescribed species, including 16 frogs, at least 3 fish, several insects and spiders, a bat, and a giant rat, measuring 82 cm in length and weighing approximately 1.5 kg. Mount Bosavi is also the type locality for Pseudohydromys pumehanae, a recently described species of moss-mouse.

In 1917 Dr. Van Hoepen discovered the fossil holotype of Elliotsmithia. The holotype consisted of a skull, mandibles with most of the front region missing, the first four cervical vertebrae complete with atlas-axis complex, rib fragments, and dermal ossifications. Van Hoepen found the fossil in rocks associated with the Tapinocephalus Assemblage Zone near the town Prince Albert in the Western Cape. The specimen remained undescribed until renowned paleontologist and physician, Dr. Robert Broom, briefly described and named the fossil in 1937.

Biblis hyperia, the red rim or crimson-banded black, is a species of brush- footed butterfly (family Nymphalidae) that is native to the lower Rio Grande Valley of Texas in the United States, Mexico, the Caribbean, Central America, and South America as far south as Paraguay. Its genus Biblis is so far monotypic, but at least one other undescribed species is suspected to exist. They can be seen flying between March and November in subtropical forest. The immature larvae feed on Tragia volubilis.

The Charco La Palma pool and its spring had a combined area of about and was no more than at the deepest point, making the range of the La Palma pupfish perhaps the smallest known for any vertebrate species. This tiny spring pond also was the home of a now-extinct, undescribed species of Cambarellus crayfish. The La Palma pupfish is a ray-finned fish which can grow up to long. Their color ranges from almost gray to a deep blue.

Euzetia is the only genus in the subfamily Euzetiinae, a group of flatworms which parasitize Elasmobranchs. As of 2008, only two species have been described in the genus, however others may remain undescribed. The genus consists of Euzetia occultum, which is the type species for the genus, and Euzetia lamothei, which was described in 2008. E. occultum parasitizes the Australian cownose ray, Rhinoptera neglecta, while E. lamothei parasitizes a different species in the same genus, the cownose ray, Rhinoptera bonasus.

There are currently four valid species within the genus Ignacius: I. frugivorus, I. fremontensis, I. clarkforkensis, and I. graybullianus. There are also at least two undescribed species of Ignacius from the Arctic of Canada. The type species for the genus Ignacius is I. frugivorus and was found at the Mason Pocket locality in Colorado. The holotype specimen (AMNH 17368), published in 1921 by Matthew and Granger, consists of an upper jaw with the canine, fourth premolar, first molar, and second molar.

The superfamily Chrysidoidea is a very large cosmopolitan group (some 6,000 described species, and many more undescribed) , including many parasitoid or cleptoparasitic wasps. There are three large, common families (Bethylidae, Chrysididae, and Dryinidae) and four small, rare families (Embolemidae, Plumariidae, Sclerogibbidae, and Scolebythidae). Most species are small (7 mm or less), almost never exceeding 15 mm. This superfamily is traditionally considered to be the basal taxon within the Aculeata, and, as such, some species can sting, though the venom is harmless to humans.

Although the species was first described in 1988 by Wolfgang Böhme et al. under the name Varanus yemensis, specimens have been collected since the late 19th century to be held by the British Museum by 1903. However, it was assumed that they were mislabelled and actually came from Africa. The discovery was made in an odd manner: two years before the first description Wolfgang Böhme recognized a yet undescribed species of monitor lizard filmed in a TV documentary about nature in Yemen.

Indeed, ongoing gene flow or incomplete lineage sorting is indicated between these populations. Thus it is not certain whether they constitute one, three, or even more species, and more research is required.Tolley et al. (2004) Another undescribed dwarf chameleon, the bright green emerald dwarf chameleon, found in the Drakensberg between of 29°15′S and 29°45′S, is now known to be closely related to the Natal Midlands dwarf chameleon and may yet be described as a separate species.

The frill-necked monarch was first described in 1895 by English ornithologist and ex-clergyman Charles Walter De Vis, from a specimen collected by Kendall Broadbent that year. However, undescribed specimens had existed in the Macleay Museum in Sydney and the National Museum in Melbourne for twenty years beforehand. The first eggs were collected by H. G. Barnard the following year in Somerset, Cape York. The frill-necked monarch is a member of a group of birds termed monarch flycatchers.

Both glassfrogs and the Allophrynidae are closely related to Leptodactylidae. Recently, an undescribed species of frog, which probably belongs to the genus Allophryne, was discovered in Peru . This suggests the genus is actually more widespread and more species await discovery. As A. ruthveni was assumed to be a northwestern Amazonian endemic, the Peruvian frog indicates the Allophrynidae might have been more widespread in prehistoric times, only later on disappearing from most of the Amazon Basin, and are actually a relict group.

In 1859 coal mine administrator Pawlowitsch notified the University of Vienna that some fossils had been found in the Gute Hoffnung mine at Muthmannsdorf in Austria. A team headed by geologists Eduard Suess and Ferdinand Stoliczka subsequently uncovered numerous bones of several species, among them those of a euornithopod dinosaur. Stored at the university museum, the finds remained undescribed until they were studied by Emanuel Bunzel from 1870 onwards. Bunzel in 1871 named the euornithopod a new species of Iguanodon: Iguanodon suessii.

The eastern feather-flower was first formally described by Ferdinand von Mueller, who gave it the name Verticordia wilhelmii, adding that it is an "exceedingly pretty little bush". The description was published in his book Definitions of rare or hitherto undescribed Australian plants. In 1922, Edwin Cheel changed the name to Homoranthus wilhelmii. The specific epithet (wilhelmii) commemorates Carl Wilhelmi, a collector of seeds and specimens of the region, who obtained the type specimen at Port Lincoln in November 1854.

The Kagera River basin is rich in fish. , there were at least 55 species known from the Rwandan section alone and the actual number is likely higher. Additionally, there are at least 15 undescribed species of haplochromine cichlids that are endemic to some of the lakes in the upper parts of the river basin. Because of the many waterfalls and rapids, the various sections of the Kagera River basin are clearly separated, making movements between them difficult or even impossible to fish.

In the upper Denwa Formation, Shringasaurus coexisted with the lungfish Ceratodus sp. and a variety of temnospondyl amphibians, including the capitosaurid Paracyclotosaurus crookshanki, the mastodonsaurid Cherninia denwai, a lonchorhynchine trematosaurid, and a brachyopid. Other terrestrial vertebrates include a large undescribed rhynchosaur and two species of dicynodonts, a mid- sized species similar to Kannemeyeria and a larger species interpreted as similar to Stahleckeria. The environment is interpreted as representing a dry, semi-arid floodplain with slow moving, anabranching rivers that periodically burst their banks.

The Hispaniolan giant tree frog (Osteopilus vastus), or Hispaniola tree frog, is a species of frog in the family Hylidae endemic to Hispaniola and found in both the Dominican Republic and Haiti. It is patchily distributed in across the island. Populations from the southern part of Hispaniola may represent a separate, as yet undescribed species. These frogs are primarily found in mesic broadleaf forests but also in a range of agricultural habitats, such as cacao and coffee plantations and pastures.

The same year, Crampton transferred the fossil to Dublin to be displayed as a centrepiece at the 1853 British Association annual meeting. The Zoological Society of Ireland built a specially constructed building to house the large reptile. After a decade, still remaining undescribed, the specimen moved in the Royal Dublin Society museum and officially described by Alexander Carte and W. H. Bailey as a new species of Plesiosaurus. Carte and Bailey named the species Plesiosaurus cramptoni after the Irish scientist, Sir Philip Crampton.

Skull of an undescribed species known as "Ronaldoraptor" The most characteristic feature of this group is the skull structure. Oviraptorids had short snouts and very deep mandibles. Some taxa (Oviraptor, Citipati, Rinchenia) had a midline crest on top of the skull, resembling that of a cassowary. Other distinguishing characteristics include a bony spike intruding on the mandibular fenestra, nostrils placed very high and far back on the snout, an extremely thin bony bar beneath the eye, and highly pneumatized skull bones.

Bracelets have not always been awarded for winning events. In 1970, the first WSOP Champion received nothing but a silver cup and whatever cash he won during the event.The first WSOP was not a freeze out tournament, but rather a collection of the top players playing against one another and the eventual winner was determined by a vote. Johnny Moss Biography PokerPlayerPress.com From 1971–1974, according to Becky Behnen (the daughter of WSOP founder Benny Binion), the winner received an undescribed "corny trophy".

"Heilongjiangosaurus" (meaning "Heilongjiang lizard") is the informal name given to an as-yet undescribed genus of duckbilled dinosaur from the Late Cretaceous. It possibly was a lambeosaurine, and may in fact be the same animal as Charonosaurus. The fossils were found in Maastrichtian-age rocks in Heilongjiang, China. As a nomen nudum, it is unclear what material it was intended to be based on, but might be connected to the nomen nudum "Mandschurosaurus" jiainensis, informally named in a 1983 publication.

"Koreanosaurus" (meaning "Korean lizard") is the informal name given to an as-yet undescribed genus of dinosaur from the Early Cretaceous. It was a possible dromaeosaur (or similar theropod) which lived in what is now Korea, although at times it has been referred to the Tyrannosauridae and Hypsilophodontidae. Based solely on a femur, the name was coined by Kim in 1979, but by 1993 Kim decided that it was a species of Deinonychus, and created the informal name "D." "koreanensis".

"Orcomimus" (Pronounced or-coh-MEEM-us) is the name given to an as yet undescribed genus of dinosaur from the Late Cretaceous period 66 million years ago. The dinosaur was an ornithomimid which lived in what is now South Dakota, in the United States. The type was coined by Michael Triebold in 1997, but has never been formally described and is currently a nomen nudum. "Orcomimus" was a bipedal theropod, but the dinosaur is known from only a pelvis and a hindlimb.

One of the last species, Mekosuchus inexpectatus from Holocene New Caledonia, may have been arboreal. The early Miocene species, Harpacochampsa camfieldensis, may have resembled a false gharial. Another mekosuchine fossil, currently undescribed, has been found in Miocene deposits from New Zealand. One genus, Mekosuchus, managed to spread to the islands of the Pacific; it is believed to have island-hopped across the Coral Sea, moving first to a now submerged island known as Greater Chesterfield Island, then New Caledonia and onwards.

Leptospermum deanei was first formally described in 1989 by Joy Thompson in the journal Telopea from specimens collected near Devlins Creek in 1982. Specimens of this species were collected in 1883 by the railway engineer Henry Deane at Devlins Creek in the Lane Cove River valley and were probably collected by Deane when he was working on the nearby railway line. These specimens lay undescribed for over 100 years in the National Herbarium of New South Wales query box. The specific epithet honours Henry Deane.

Positive allometry has not been demonstrated in eurypterid chelicerae as a whole in any other eurypterid genus, including in the closest relatives of Jaekelopterus. There are also some undescribed specimens of J. rhenaniae similar in proportions to the large chelicera, including another claw found in the same strata as the original find. In the opinion of Braddy, Poschmann and Tetlie, who replied to Kaiser and Klok the same year, the size estimates around remain the most accurate estimates on the maximum size of the species yet.

This nudibranch has a white dorsum with rounded black spots in a single row along both sides of the body, with a spot at the front, in front of the white rhinophores, and a similar spot at the back of the mantle. It is a moderately large Phyllidiid, growing to about 40 mm in length. It is similar to Phyllidia scottjohnsoni but that species has black spots along the midline of the back. It is possible that there are several undescribed species with similar coloration.

But while they are highly diverse, they are not particularly speciose, with nearly 20 described and a few undescribed species compared to the more than 150 Hawaiian species of Proterhinus of the Aglycyderini. The fossil record shows that the three Oxycoryninae tribes were well distinct by the mid-Paleogene, about 50 million years ago (mya). The belids as a whole are of Jurassic origin, and the Oxycorynini must thus have evolved in the Late Cretaceous or perhaps Paleocene, roughly some 100-60 mya.Marvaldi et al.

An undescribed catfish (Clarias spp) and barb (Barbus spp) as well as the atyid shrimp Caridina sodenensis are endemic species to this lake. Majority of the region is located on the African Precambrian shield which contains principally basement rocks. Over the years, the weathering of these basement rocks has created dense layers of leached and poor red earth soils. Meanwhile, along the Atlantic Equatorial coastal forests, the continuous deposition of sand, rocks and silt has created extensive muddy banks, mangrove swamps and sandy beaches.

Neotropical Ichthyology, 6 (3): 315–322. Some authors have tentatively defined putative monophyletic assemblages within the genus Trichomycterus based on the possession of unique morphological features. The Trichomycterus brasiliensis species-complex includes T. brasiliensis, T. iheringi, T. maracaya, T. mimonha, T. pirabitira, T. potschi, T. vermiculatus and several undescribed species apparently endemic to the main river basins draining the Brazilian Shield.Bockmann, F.A. & Sazima, I. (2004): Trichomycterus maracaya, a new catfish from the upper rio Paraná, southeastern Brazil (Siluriformes: Trichomycteridae), with notes on the T. brasiliensis species-complex.

Plumalexius rasnitsyni Sphecomyrma mesaki The organisms preserved in New Jersey amber are diverse, with fungus, plant, and animal inclusions having been described. Fungi are represented by a single described Agaricales species. Plant fossils are also sparse, with conifer shoots from a Cupressaceae member, plus several undescribed flowers from a fagalean angiosperm. Of the inclusions found in Sayreville ambers, 34% are identified as dipterans, while a 2001 paper notes that up to 20% of the inclusions found in New Jersey amber are of coccoid true bugs.

Danakilia is a genus of cichlids native to northeastern Africa where they are only known from saline lakes, rivers and creeks in the Danakil Depression of Ethiopia and Eritrea. There are two formally described species, along with three undescribed species currently known.Giorgio Chiozzi, Melanie L. J. Stiassny, S. Elizabeth Alter, Giuseppe De Marchi, Yohannes Mebrahtu, Misikire Tessema, Berhan Asmamaw, Mauro Fasola & Adriana Bellati (2017). Fishes in the desert: mitochondrial variation and phylogeography of Danakilia (Actinopterygii: Cichlidae) and Aphanius (Actinopterygii: Cyprinodontidae) in the Danakil Depression of northeastern Africa.

Another type of atypical type of centriole was discovered in human and bovine sperm. This is the distal centriole of the spermatozoon, which has atypical structure and composition. This spermatozoon distal centriole is composed of splayed microtubules surrounding previously undescribed rods of centriole luminal proteins, and it has only a subset of the protein found in a typical centriole. After fertilization, the atypical distal centriole that is attached to the sperm tail recruits pericentriolar material, forming a new centriole, and localizing to the spindle pole during mitosis.

New Zealand has 99 native lizard taxa (including undescribed entities), all of which belong to genera that are endemic to the country. They are also globally significant in that they have a high level of adaptation to cold-climate living. Most lizard species bear live young, which is unusual as the majority of lizards around the world lay eggs. This adaptation enables the mother lizard to select the best available temperature for the developing young, by either sun basking or moving into a deep retreat.

The genus is restricted to the Paleotropics. Thirteen species are known from the Afrotropical and Malagasy regions, and twenty-five species and subspecies from Asia and Australia, although preliminary study suggests that there are many undescribed species. Very little is known about the biology of Paraparatrechina in the Afrotropical and Malagasy regions. They have been found in a wide range of tropical habitats from rainforests to forest clearings in sifted leaf litter, rotten logs, under stones, and from beating vegetation and fogging samples from the forest canopy.

Among the baleen whales found, the most common was an undescribed species of cetotheriid whale measuring around , and most of the other baleen whales found were roughly the same size. Toothed whale remains found consist of beaked whales (such as Messapicetus gregarius), ancient pontoporiids (such as Brachydelphis mazeasi), oceanic dolphins, and the raptorial sperm whale Acrophyseter. All seal remains found represent the earless seals. Also found were large sea turtles such as Pacifichelys urbinai, which points to the development of seagrasses in this area.

Spizellomycetalean chytrids have beneficial roles in the soil for nutrient recycling and as parasites of organisms that attack plants, such as nematodes and oospores of downy mildews. On the other hand, they also have detrimental roles as parasites of arbuscular mycorrhizae, symbiotic fungi that help plants gain essential nutrients. Culture isolation studies and molecular characterization of these fungi have demonstrated a great deal of undescribed diversity within the Spizellomycetales, even for isolates collected within the same geographic location. Thus, these understudied fungi await greater exploration.

The Cyclocorinae are a subfamily of lamprophiid snakes endemic to the Philippines. It was erected in 2017 to house 4 enigmatic, endemic genera containing 7 species and one undescribed lineage that are more closely related to one another than to members of the subfamilies Atractaspidinae and Aparallactinae or to other subfamilies of Lamprophiidae. Previously placed within Colubridae, a 2017 study by Weinell et al. found strong support the monophyly of Cyclocorinae within Lamprophiidae, but its position relative to the other subfamilies of Lamprophiidae is not resolved.

Most species in the genus are seriously threatened. C. arcuatus, C. ceciliae, C. inmemoriam, C. nevadensis calidae and an undescribed species popularly known as the "Perrito de Sandia" are already extinct. C. arcuatus was restricted to springs in the US state of Arizona and probably also in the Mexican state of Sonora, while all the others were restricted to spring systems in Mexico. Three species from southwestern Nuevo León, C. alvarezi, C. longidorsalis and C. veronicae, have become extinct in the wild, only surviving in captivity.

Goliath beetle Insects, a class of Arthropoda, are easily the most numerous class of organisms, with over one million identified species, and probably many undescribed species. The heaviest insect is almost certainly a species of beetle, which incidentally is the most species-rich order of organisms. Although heavyweight giant wetas (Deinacrida heteracantha) are known, the elephant beetles of Central and South America, (Megasoma elephas) and (M. actaeon), the Titan beetle (Titanus giganteus) of the neotropical rainforest or the Goliath beetles, (Goliathus goliatus) and (G.

The Ivindo below Makokou was first traversed by a whitewater expedition in 1998. This was a group from Jackson Hole, Wyoming, consisting of Chris Guier, Bruce Hayse, Louise Lasley, Marilyn Olsen, Rick Sievers and Howie Wolke. The group encountered four impressive falls: Kongue, Mingouli, Tsengue Leledei, and an unnamed and undescribed falls between Mingouli and Tsengue Leledei which was perhaps the most beautiful of all. There were many stretches of whitewater and the banks were remarkable for groups of unafraid elephants and occasional other mammals.

The orange pea-shaped flowers are produced between November and January in the species' native range. The species was formally described in 1855 by botanist Ferdinand von Mueller in his paper Definitions of rare or hitherto undescribed Australian Plants, chiefly collected within the boundaries of the colony of Victoria. Mueller gave it the name Oxylobium procumbens Mueller and noted occurrences at Mount Disappointment, the Black Forest, the Goulburn Ranges, along the Delatite River and at Ballarat. The species was transferred to the genus Podolobium in 1995.

In Nepenthes of Sumatra and Peninsular Malaysia, Charles Clarke mentions an undescribed taxon from Aceh that is intermediate in appearance between N. lavicola and N. spectabilis. It is unlikely to be of hybridogenic origin as it is not sympatric with any other Nepenthes species. Nepenthes rigidifolia also bears a superficial resemblance to N. spectabilis, particularly in the colouration of its pitchers. Apart from its markedly different upper pitchers, N. spectabilis differs from the former in having thin leaves, an unbranched spur, and an apical tendril insertion.

The distribution of Dinopanorpidae is restricted both in time and in location. An undescribed species of Dinopanorpa has been reported from the Paleocene Tadushi Formation, while the type and only specimen of Dinopanorpa megarche is from the Khutsin Formation of Primorsky Krai, Russia. The Khutsin Formation has been interpreted as dating from the early Eocene to the late Eocene/early Oligocene boundary. The genus Dinokanaga is known exclusively from fossil sites in western North America, which date to the Ypresian and constitute the Okanagan Highlands paleobiotic communities.

The whole complex of U. sikorae is in need of taxonomic revision and probably contains numerous new, undescribed species. The genus Uroplatus contains 14 species endemic to Madagascar. The species Uroplatus sameiti was considered to be a subspecies of U. sikorae until 2007, when it was proposed to be elevated to species level on the basis of its pale oral mucosa, in contrast to the dark oral mucosa of U. sikorae. Subsequent publications have maintained this separate status, which has now also been verified molecularly.

Corydoras loxozonus is a tropical freshwater fish belonging to the Corydoradinae sub-family of the family Callichthyidae. It originates in inland waters in South America, and is found in the Meta River basin in Colombia. In the system of "C-Numbers" developed by the German fishkeeping magazine DATZ to identify undescribed species of Corydoras in the aquarium hobby, this fish had been assigned numbers "C79", "C82", and "C83" until these stocks were correctly identified. The fish will grow in length up to 1.9 inches (4.9 centimeters).

Corydoras osteocarus is a tropical freshwater fish belonging to the Corydoradinae sub-family of the family Callichthyidae. It originates in South America, and is found in the Orinoco River basin in Venezuela and coastal rivers in Suriname. In the system of "C-Numbers" developed by the German fishkeeping magazine DATZ to identify undescribed species of Corydoras in the aquarium hobby, this fish had been assigned number "C60" until it was correctly identified. The fish will grow in length up to 1.6 inches (4.0 centimeters).

Three other specimens were referred to this species but remain undescribed. Like P. neimongoliensis, this species was discovered in the Eijnhoro Formation. Sereno (2010) found the species as described to be indistinguishable from P. sinensis, another small species, but suggested that additional study of P. ordosensis might reveal diagnostic features. He provisionally designated P. ordosensis a nomen dubium. ;P. mazongshanensis? Xu Xing, another Chinese paleontologist, named a new species of Psittacosaurus in 1997, based on a complete skull with associated vertebrae and a forelimb.

Nepenthes hurrelliana was known to botanists for some time prior to its description, although authors differed as to its identity, with most treating it as either a form of N. veitchii, a form of N. maxima, or a natural hybrid. In 1988, Anthea Phillipps and Anthony Lamb published an illustration of a N. hurrelliana specimen from Mount Murud under the name "N. veitchii × N. fusca". However, in their 1996 monograph, Pitcher-Plants of Borneo, the authors treated it as an undescribed species, "Nepenthes sp.".

University Press of Florida, Gainesville. According to Hinton, Parietaria praetermissa was for many years erroneous called Parietaria floridana. However, when Hinton examined the type specimen of P. floridana, he discovered that it was a different species, the only that had been called Parietaria nummularia. Under the rules of botanical nomenclature, this meant that P. nummularia needed to be renamed P. floridana, and the species that had long been called P. floridana was in fact an undescribed species, one which Hinton described as P. praetermissa.

With the exception of the Cynipidae (the gall wasps), it is a poorly known group as a whole, though there are nearly 3000 known species in total, and a great many species are still undescribed, mostly in the Figitidae. Each of the constituent families differs in biology, though life histories of one of the families (Liopteridae) are still largely unknown. In July 2020 an identification key for the superfamily was published in the journal Insect Systematics and Diversity, enabling identification to the family level.

Glyptonotus antarcticus at up to in length and in weight, and Ceratoserolis trilobitoides at up to in length are unusually large benthic isopods and examples of Polar gigantism. Amphipods are abundant in soft sediments, eating a range of items, from algae to other animals. The amphipods are highly diverse with more than 600 recognized species found south of the Antarctic Convergence and there are indications that many undescribed species remain. Among these are several "giants", such as the iconic epimeriids that are up to long.

521 Several other mammals have been recorded from the late Cretaceous of Madagascar, mostly on the basis of isolated teeth. A possible second gondwanathere is represented by a tooth that is larger and lower-crowned than those of Lavanify, and a yet lower-crowned tooth may also be of a gondwanathere. A lower molar, UA 8699, may be of a marsupial or a placental and a molar fragment is referable to Multituberculata. Finally, an as-yet-undescribed mammal is known from a fairly complete skeleton.

Urocyon (from the Greek word for "tailed dog"Urocyon.) is a genus of Canidae which includes the gray fox (Urocyon cinereoargenteus) and the island fox (Urocyon littoralis). These two fox species are found in the Western Hemisphere. Whole genome sequencing indicates that Urocyon is the most basal genus of the living canids. Fossils of what is believed to be the ancestor of the gray fox, Urocyon progressus, have been found in Kansas and date to the Upper Pliocene, with some undescribed specimens dating even older.

Non-archosaurs are also present in the Yanliao Biota. Mammaliaforms include Liaotherium gracile, Manchurodon simplicidens, Pseudotribos robustus, Volaticotherium antiquum, Castorocauda lutrasimilis, Docofossor brachydactylus, Arboroharamiya jenkinsi, Megaconus mammaliaformis, Xianshou linglong and X. songae, Shenshou lui, and Juramaia sinensis. Additionally, there are lizards, including "Yabeinosaurus" youngi; an undescribed crocodylomorph; salamanders, including Chunerpeton tianyiensis, Jeholotriton paradoxus, Liaoxitriton daohugouensis, and Pangerpeton sinensis; and fish, including Liaosteus hongi and a member of the Ptycholepidae. In terms of environment, the Tiaojishan Formation represents a forested woodland with conifers, cycads, and ferns.

In 1993 and 1994, the species was observed in the Sierra Madre, at an altitude between , but this probably concerns a population of a separate, undescribed species. A second species within the A. datae group was described by Luis Ruedas, in 1995: Apomys gracilirostris. In the 21st century, the knowledge about A. datae was expanded with data from genetic research. In 2002, the karyotype was revealed, and in 2003, the phylogenetic relationship with A. gracilirostris was confirmed, based on common features in the species' DNA.

It belongs to a group including C. bilineata, C. narentana and an undescribed species from the Bosnian-Croatian border region. The Adriatic endemics separated from the ancestors of C. bilineata, today widespread immediately south of the Alps, around 6–5.5 million years ago. This was during the Messinian salinity crisis, when drainage basins throughout the Mediterranean region changed their course. C. dalmatina appears to be quite similar to C. narentana as regards the mitochondrial DNA sequence, but the nuclear DNA sequences differ far more.

"Futabasaurus" is an informal name for a genus of theropod dinosaur from the Late Cretaceous of Japan, known only from a partial shin bone discovered in the Coniacian-age Ashizawa Formation of the Futaba Group. It was coined by David Lambert in 1990 as a conversion from the Japanese nickname "Futaba-ryu", for an undescribed theropod. Dong Zhiming and coauthors briefly discussed the fossil shin bone it was based on that same year, publishing a photograph. They considered the bone to belong to an indeterminate tyrannosaurid.

The size of the holotype specimen is difficult to assess, as the two most characteristic elements of the skeleton, the skull and the humerus, are proportionally unusual. Estimating body size from the skull predicts a much larger humerus, and estimating it from the humerus predicts a much smaller skull. This may indicate that the skull was unusually large, the forelimbs were unusually small, or both. Roughly scaling from local crocodylomorph taxa such as Dromicosuchus and an undescribed species (specimen NCSM 21722), Zanno et al.

The specimens did indeed suggest that a new species had been discovered, but they were not sufficient for formal publication. Early in May the following year, John Falconer drove over 2000 kilometres on unsealed tracks from Warburton to Point Culver and back again, in order to collect fresh flowers and fruit of the purported new species. Alex George then began preparing a formal description of the species. During his research, he discovered that Nelson's Toolinna Cove specimen was also referable to the undescribed species.

It is likely that it will be revised eventually; if Variabilichromis is split off, at least some of the more ancient lineages currently placed in Neolamprologus are probably worthy of separation also. However, the morphological similarity and numerous undescribed species do not make analyses easier, and as with many cichlids, recent speciation and abundant hybridization seriously confound molecular studies to the point where single-gene studies or those using only mtDNA or nDNA are essentially worthless for resolving Lamprologini phylogeny.Sturmbauer et al. (1994), Day et al.

The phylogenetic position of A. pulex is problematic. It seems to be closely related to A. diaphanus due to some derived characters of the internal anatomy, but a conclusive assessment of its relationships has not been prevented by its paedomorphic features and scarcity of study material. This generic placement seems to be well supported. The relationships of the genus Ammoglanis are unknown; it is thought that this genus along with undescribed forms are the sister group to a large intrafamilial clade composed of several genera and subfamilies.

While at the Port Erin Marine Biological Station, Parke conducted research on the commercial rearing and feeding of oyster larvae. This research lead to the description of previously undescribed micro-organisms such as Isochrysis galbana. From the 1940s Parke led the development of the Plymouth Culture Collection of marine algae and first published the Check-List of Marine Algae in 1953. After the war Parke returned to her work on minute plankton and published seminal papers on flagellate systematics, many in collaboration with Professor Irene Manton of the University of Leeds.

Only three species grow larger; two slender Ophisternon swamp eels at up to in standard length and a much more robust undescribed species of mahseer at . The very limited food resources in the habitat likely prevents larger cavefish species from existing and also means that cavefish in general are opportunistic feeders, taking whatever is available. In their habitat, cavefish are often the top predators, feeding on smaller cave-living invertebrates, or are detritivores without enemies. Cavefish typically have low metabolic rates and may be able to survive long periods of starvation.

Filimanus was described as new genus by George S. Myers in 1936 with its only species being based on a single specimen which he identified as Polynemus melanochir but which was subsequently found to be a misidentification and P. melanochir is a valid species now classified in the genus Polydactylus which meant that Myers specimen remained undescribed. Subsequently Ross M. Feltes described it as Filimanus perplexa and added 5 other species to this new genus. Opinion 1761 of the International Commission on Zoological Nomenclature confirmed F. perplexa as the type species of Myers's genus.

Gymnobela is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae. This genus can sometimes be hardly differentiated from species in the genera Spergo Dall, 1895, Theta Clarke, 1959 and Speoides yoshidae Kuroda & Habe in Habe, 1961 (a synonym of Gymnobela yoshidae (Kuroda & Habe, 1961) )Stahlschmidt P. & Chino M. (2012) A new species of Gymnobela (Gastropoda: Raphitomidae) from the Central Pacific. Miscellanea Malacologica 5(6): 95-98 This genus is highly diverse. It is rather an artificial assemblage of several unrelated genus-level lineages that are unrelated and mostly undescribed.

According to one of them, reelin makes the cells more susceptible to some yet undescribed positional signaling cascade. Reelin may also ensure correct neuronal positioning in the spinal cord: according to one study, location and level of its expression affects the movement of sympathetic preganglionic neurons. The protein is thought to act on migrating neuronal precursors and thus controls correct cell positioning in the cortex and other brain structures. The proposed role is one of a dissociation signal for neuronal groups, allowing them to separate and go from tangential chain-migration to radial individual migration.

The existence of a second smaller species related to the flathead gudgeon (Philypnodon grandiceps) had been strongly suspected since 1980. P. macrostomus was described in 2006 by Douglass Fielding Hoese and Sally Reader; the type specimen was collected in Glenreagh, New South Wales. Its species name derived from the Ancient Greek makro "large" and stoma "mouth". Genetic analysis of the species from the different river drainages across its range showed that populations from the Lang Lang River in Victoria had diverged much earlier and most likely represent a separate, as yet undescribed species.

Kalapuya brunnea is a species of truffle in the monotypic fungal genus Kalapuya. The truffle occurs only in the Pacific Northwest region of the United States, in western Oregon and northern California. Known locally as the Oregon brown truffle, it was formerly thought to be an undescribed species of Leucangium until molecular analysis demonstrated that it was distinct from that genus. The truffle is reddish brown with a rough and warty outer skin, while the interior spore-producing gleba is initially whitish before developing greyish-brown mottling as it matures.

In the year 2000 the Albany Museum based in Grahamstown initiated surveys to determine which aquatic macroinvertebrates lived in the Salt River. This study followed on a proposal to introduce trout into the river, which has no freshwater fish of its own. Some 13 undescribed species of macroinvertebrate fauna collected by researchers proved to be of great interest, ending plans for introducing trout. This number later grew to 33 new species, several of which have been described by entomologists Ferdy de Moor and Helen James from the Albany Museum.

Nematophagous fungi have been found throughout the world in a wide range of habitats and climates, but few from extreme environments. Most studied have been the species that attack the nematodes of interest to farmers, horticulturists and foresters, but there are large numbers of species as yet undescribed. The sexual stage of Orbilia occurs on rotting wood on land or in fresh water, while the asexual stage occurs in marine, fresh water and terrestrial habitats. Arthrobotrys dactyloides was the first species to be discovered in brackish water, and other species have been found on mangroves.

Vischer postulated the as yet undescribed distinction between verstehen and Einfühlung (“in-feeling” or “feeling-into”) in his 1873 doctoral thesis On the Optical Sense of Form: A Contribution to Aesthetics. In It was the first mention of the word Einfühlung in this form in print. His more-famous father, Friedrich Theodor Vischer, had used the term Einfühlen in explorations of Idealism relative to architectural form, and related concepts were certainly already in the air. Indeed, the phrase "sich einfühlen" was used by Herder in the 18th century.

The eel-tailed catfish is found in most freshwater habitats of the Murray-Darling river system except for the upland, sub-alpine and alpine headwaters of southern tributaries. It is also present in speciated but undescribed forms in several east coast systems in northern New South Wales due to natural river capture events. Juvenile eel-tailed catfish feed on zooplankton, and small insects, particularly chironomid larvae. Fish over about 100 mm also eat small fish while adults include shrimps, crayfish in the warmer months and midge larvae in winter.

The first specimens of a Dryandra were collected by Archibald Menzies, surgeon and naturalist to the Vancouver Expedition. At the request of Joseph Banks, Menzies collected natural history specimens wherever possible during the voyage. During September and October 1791, while the expedition were anchored at King George Sound, he collected numerous plant specimens, including the first specimens of B. sessilis (Parrotbush) and B. pellaeifolia. Upon Menzies' return to England, he turned his specimens over to Banks; as with most other specimens in Banks' library, they remained undescribed for many years.

They noted that the species had unique features different from Agathidium and other beetles, and labelled them under "Undescribed Genus 7". With reexamination of the tribe Agathidiini to which they belong, they were reclassified under a new genus Gelae in 2004. Kelly B. Miller and Quentin D. Wheeler described their significant characters and regrouped them, along with five new species, G. baen, G. belae, G. donut, G. fish, and G. rol. They derived the name from a Latin word gelatus, which means "congealed" or "jellied", and to be pronounced like the English word "jelly".

The several species of Stethacanthus discovered in the late 1800s were established based solely upon isolated spines, which initially confused paleontologist John Strong Newberry into thinking the spines constituted a new kind of fin. He originally believed that the spines were part of the pectoral fins and that they were not bilaterally symmetrical. Meanwhile, the first associated skeletal remains found in the Mississippian of Montana and the Devonian and Mississippian of Ohio remained undescribed for nearly a century. Since complete skeletons were extremely rare, Stethacanthus classification was vague and based on few characteristics.

Micryletta inornata is a rare species of frog in the family Microhylidae. It is endemic to the island of Sumatra in Indonesia, and is the type species for the genus Micryletta. Many populations of Micryletta found across southeast Asia and the Andaman Islands were formerly classified under this species, but a 2019 study found most of these to represent either undescribed taxa of Micryletta or to fall under already-described related species such as M. erythropoda. Due to this, the study restricted the designation of M. inornata to just the populations known from Sumatra.

Boettger's horned toad (Megophrys boettgeri), also known as Boettger's spadefoot toad or the pale-shouldered horned toad, is a species of toad found in southern and southeastern China (the northern border runs roughly from Sichuan in the west to Shanxi in the north and Zhejiang in the east) and north-eastern India (Arunachal Pradesh, Sikkim, and Assam). A closely related but probably as yet undescribed species in found in Tibet. It is not certain that the Indian specimens belong to Megophrys boettgeri either. The history of this species' discovery is highly international.

Lucihormetica is a South American genus of giant cockroaches from the family Blaberidae, collectively referred to as glowspot cockroaches.Uniport Taxonomy It has been anecdotally reported that the thoracic spots of males are bioluminescent, but detailed research has been unable to conclusively prove this, although evidence for autofluorescence exists. The genus includes both relatively common and rare species: For example, L. verrucosa is relatively common and sometimes kept in captivity, while eight of the remaining species (as well as an additional undescribed species) only are known from a single specimen each.

However, this classification has been questioned by Storrs Olson when he described Brodkorb's material anew in 1974. It is only known by Brodkorb's holotype which consists of a humerus and several leg elements including femur, tibiotarsus and tarsometatarsus fragments. The humerus may not be specifically distinct from those of the American coot (Fulica americana) but most of the femur, tibiotarsus and tarsometarsus fragments are from a yet undescribed larger rail of an undetermined genus not related to Fulica. Olson further assumed that Brodkorb's material might be a composite of several rail species.

Eocypraeidae is a small family of large sea snails, marine gastropod molluscs in the superfamily Cypraeoidea, the cowries and cowry allies. The family Eocypraeidae consists mainly of fossil species, except for two species: Sphaerocypraea incomparabilis Briano, 1993 (regarded as valid) and an as yet undescribed species found in the southern Atlantic. In 1963, a fresh shell of what was subsequently named Sphaerocypraea incomparabilis was dredged up by a Soviet trawler in the Gulf of Aden. There are currently (2009) only six known specimens of this shell in various collections.

Most research in the area of squamata reproductive organs has focused on the male hemipenis, but a recent study has started to investigate the homologous paired structures in females, dubbed "hemiclitores". Researchers investigated females of Phymaturus and Liolaemus lizards and discovered a structure that was previously undescribed. The hemiclitoris was observed to be smaller than a hemipenis, and the organs were consistently observed in the lizards in the study. While the specific functions are yet to be identified, this study brings attention to a squamata apomorphy that will likely continue to be investigated in detail.

These findings were also reinforced by the initial DNA studies conducted on the genus, which only revealed two phylogenetic species. More recently, a 2017 study determined that there were likely five Nautilus species, however these did not exactly correlate to the described species of the genus. Whilst the status of N. Macromphalus, N. Stenomphalus, and N. Pompilius were validated by the genetic study, two undescribed, but genetically distinct, species were discovered in the South Pacific. One of these cryptic species was recorded from Vanuatu, whilst the other from Fiji and American Samoa.

Barraband's mystery black-breasted twelve-wired bird-of-paradise. 18th century French artist Jacques Barraband, known for his ability to illustrate birds with a high degree of accuracy, produced a few illustrations of unidentified birds-of- paradise. It has been postulated that these paintings may be simply inaccurate, depict undescribed species, or depict hybrids that have not since been observed. On 15 May 2004, New Scientist published one of these paintings, which depicts a bird that most closely resembles the twelve-wired bird-of- paradise, although there are several obvious differences.

Scarlett's duck (Malacorhynchus scarletti) is an extinct duck species from New Zealand which was closely related to the Australian pink-eared duck (Malacorhynchus membranaceus). The scientific name commemorates the late New Zealand ornithologist and palaeontologist Ron Scarlett who discovered the holotype in 1941. However, previously undescribed bones of the species found in 1903 were rediscovered in the Otago Museum in 1998. At least 32 fossil remains from deposits in Pyramid Valley, at Ngapara in the South Island, and at Lake Poukawa in the North Island are in museum collections.

The narrator of the story implies that the person named Hali is now dead (at least in the timeline of the story). Several other nearly undescribed places are alluded to in Chambers' writing, among them Hastur, Yhtill, and Aldebaran. "Aldebaran" may refer to the star Aldebaran, likely as it is also associated with the mention of the Hyades star cluster, with which it shares space in the night sky. The Yellow Sign, described as a symbol, not of any human script, is supposed to originate from the same place as Carcosa.

Many other endemic species of Réunion became extinct after the arrival of man and the resulting disruption of the island's ecosystem. The Réunion ibis lived alongside other recently extinct birds such as the hoopoe starling, the Mascarene parrot, the Réunion parakeet, the Réunion swamphen, the Réunion owl, the Réunion night heron, and the Réunion pink pigeon. Extinct reptiles include the Réunion giant tortoise and an undescribed Leiolopisma skink. The small Mauritian flying fox and the snail Tropidophora carinata lived on Réunion and Mauritius, but vanished from both islands.

Thaumatomyrmex use their long mandibles to hold the polyxenids before immobilizing them by stinging, and then stripping the prey from their protective setae. The brush-like hairs on the workers' legs are used to scrape the setae off "like cleaning a chicken".E. O. Wilson (professor emeritus, Harvard) in an interview in New Scientist issue No3005 page 29 Workers forage individually in the leaf litter. Alate queens remain undescribed, although Kempf (1975) mentioned an alate T. zeteki queen in the collections of the U.S. National Museum, this has however never been confirmed.

The eggs are undescribed, but tyrant flycatchers typically lay two eggs which are incubated by the female for 15–16 days to hatching, The tawny- chested flycatcher is 12 cm long, weighs 7 g and looks like a colourful Empidonax flycatcher in size and structure . It has a grey head with a white throat and white spectacles. The upperparts are olive-green, and the wings are dusky with two bright ochre wing bars and ochre edging to the secondary feathers. The breast is ochre-orange, becoming bright yellow on the belly.

The species was first described in 1994 as Emydura lavarackorum after fossil material was found in Riversleigh in northwest Queensland. It was later demonstrated anatomically that because of its anterior bridge struts that it actually belonged to the genus Elseya and further to a living, although undescribed form. The species was also declared at this time to be Australia's first living fossil freshwater turtle and an extant population of a Pleistocene taxon. The latter gained significant public attention to this species after a story was published in Discover Magazine in January 1997.

The species was mentioned as an undescribed taxon in Charles Clarke's 2001 monograph, Nepenthes of Sumatra and Peninsular Malaysia, under the name "Nepenthes species B". Clarke considered it to be most closely allied to N. singalana, writing that "[f]urther research is required to determine whether or not this is simply an unusual variety of N. singalana, or whether it warrants description as a distinct species". Flowering-size specimens of N. izumiae, identified as N. singalana from Mount Talakmau, were already in cultivation before the species was formally published.Mansell, G. N.d. New Nepenthes: Nepenthes izumeae .

Additional herbarium specimens of N. mikei are known and these show slight morphological variability. In 1997, Matthew Jebb and Martin Cheek published their monograph "A skeletal revision of Nepenthes (Nepenthaceae)", in which they provided an emended description of N. mikei that encompassed specimens of the closely related, and at the time undescribed, N. angasanensis from Mount Leuser, Goh Lembuh, and the Kappi region. Salmon and Maulder did not support this interpretation and reinstated their original description of N. mikei when they described N. angasanensis in 1999.Salmon, B.R. & R.G. Maulder 1999.

The bird has been discovered in the remote Yariguies mountains in an expedition co-led by Thomas Donegan of Fundación ProAves and Blanca Huertas, a curator at the Natural History Museum in London. According to the researchers, the region was so little explored that several more hitherto undescribed birds and butterflies are found there (Donegan & Huertas, 2006). Huertas, a lepidopterologist by training, found several taxa of butterflies new to science (Huertas & Arias 2007). Further information about the biological exploration of the region is found in expedition reports (Donegan & Huertas 2005; Huertas & Donegan 2006).

Auer rods are found only in neoplastic cells and are used in the diagnosis of acute promyelocytic leukemia, though they do not indicate the prognosis of a patient. There is some controversy in the eponymous nature of Auer rods. Auer is credited with the first descriptions and illustrations of Auer rods in his 1906 publication, "Some hitherto undescribed structures found in the large lymphocytes of a case of acute leukemia." As acknowledged by Auer in the paper, the inclusions had been previously noted in a paper authored by Thomas McCrae.

Paclitaxel was identified from Pacific yew tree Taxus brevifolia. Paclitaxel showed anti-tumour activity by a previously undescribed mechanism (stabilization of microtubules) and is now approved for clinical use for the treatment of lung, breast, and ovarian cancer, as well as for Kaposi's sarcoma. Early in the 21st century, Cabazitaxel (made by Sanofi, a French firm), another relative of taxol has been shown effective against prostate cancer, also because it works by preventing the formation of microtubules, which pull the chromosomes apart in dividing cells (such as cancer cells). Other examples are: 1.

Due to its incomplete features and lack of information on the geological setting, the species remained undescribed at the museum of University of California, Berkeley. James Parham, who is one of the taxonomic authorities of the species, had seen the original fossils at Berkeley while still a PhD candidate in 1996. He recalled, "If I had known how old the specimens at Berkeley were in 1996, I would have included them in my dissertation, for sure." Better specimens were discovered in 2007 by hobby palaeontologists, Mary Luz Parra and her brothers Juan and Freddy Parra.

Haplochromis latifasciatus is one of the many cichlid species found only in the Lake Kyoga system Nile crocodiles are numerous, as is other aquatic fauna. There are at least 60 haplochromine cichlid species, as well as a smaller number of other fish species like Lake Victoria sardine and marbled lungfish. Many of the haplochromine cichlids are endemic, but very closely related to the Lake Victoria species, and showing a similar level of diversity in terms of feeding. The Kyoga cichlids include both described species like Haplochromis latifasciatus and H. worthingtoni, and undescribed like H. sp.

There are relatively few fish species in few families in the Southern Ocean. The most species-rich family are the snailfish (Liparidae), followed by the cod icefish (Nototheniidae) and eelpout (Zoarcidae). Together the snailfish, eelpouts and notothenioids (which includes cod icefish and several other families) account for almost of the more than 320 described fish species of the Southern Ocean (tens of undescribed species also occur in the region, especially among the snailfish). Southern Ocean snailfish are generally found in deep waters, while the icefish also occur in shallower waters.

G. monumentensis is known from a skull and partial skeleton from Utah. G. monumentensis was listed second on the top 10 list of new species in 2008 by the International Institute for Species Exploration. Recently, a possible fourth species of Gryposaurus, Gryposaurus alsatei, was unearthed in the Javelina Formation, which dates to the late Maastrichtian, along with an unnamed species of Kritosaurus and an undescribed saurolophine which closely resembles Saurolophus, but with a more solid crest. The dubious hadrosaurid Stephanosaurus marginatus was considered a possible species of Kritosaurus, following the synonymy of Gryposaurus with Kritosaurus.

The barredtail corydoras or Cochu's catfish (Corydoras cochui) is a tropical freshwater fish belonging to the Corydoradinae sub-family of the family Callichthyidae. It originates in inland waters in South America, and is found in the Upper Araguaia River basin in Brazil. In the system of "C-Numbers" developed by the German fishkeeping magazine DATZ to identify undescribed species of Corydoras in the aquarium hobby, this fish had been assigned number "C22" until it was correctly identified. The fish will grow in length up to 1 inches (2.5 centimeters).

It required discovery of the previously undescribed Geosmithia fungus - and an appreciation of its role in canker production - to complete an understanding of how the disease can develop. The initial description of the thousand cankers disease was constructed in early 2008 by researchers at Colorado State University and subsequently information was extended to alert researchers, arborists and others with interest in tree health care. This led to numerous new TCD records in the western US during 2008 and 2009. Initial description of thousand cankers disease in a refereed journal occurred in August 2009.

The greenback stingaree was described by Australian ichthyologist Allan Riverstone McCulloch in a 1916 volume of the scientific journal Biological Results Endeavour, who gave it the specific epithet viridis from the Latin word for "green". The type specimen was collected from a depth of off Green Cape in New South Wales, by the research vessel FIS Endeavour. An undescribed stingaree possibly belonging to this species has also been found in deep water off southwestern Australia; it is very similar to the greenback stingaree but has more pectoral fin rays (106-107 versus under 100).

A hitherto undescribed Gallirallus rail also inhabited Lakeba and Aiwa in the past; as this bird was flightless it represents an endemic species. The consumed scrubfowl (Megapodius alimentum), a species rather widely distributed throughout Fiji and Tonga, also occurred on Lakeba and Aiwa in the past; as scrubfowl were widely transported across islands by settlers, this species might have been brought here by humans, but altogether this is not too likely. However, on Aiwa a single bone was found, probably referrable either to the Viti Levu scrubfowl (M. amissus) or the pile-builder megapode (M.

Among the specimens studied was a previously undescribed specimen of Sinosauropteryx, IVPP V14202. By examining melanosome structure and distribution, Zhang and colleagues were able to confirm the presence of light and dark bands of colour in the tail feathers of Sinosauropteryx. Furthermore, the team was able to compare melanosome types to those of modern birds to determine a general range of colour. From the presence of phaeomelanosomes, spherical melanosomes that make and store red pigment, they concluded that the darker feathers of Sinosauropteryx were chestnut or reddish brown in colour.

The Xingu corydoras (Corydoras xinguensis) is a tropical freshwater fish belonging to the subfamily Corydoradinae of the family Callichthyidae. It originates in inland waters in South America, and is found in the upper Xingu River basin in Brazil. It is named for the river in which it is found. In the system of "C-Numbers" developed by the German fishkeeping magazine DATZ to identify undescribed species of Corydoras in the aquarium hobby, this fish had been assigned numbers "C55", "C105", "C106", "C107", and "C108" until these were correctly identified.

This intermediate population is sometimes referred to as M. cf. expectata, whereas the so-called "desert mantella", a likely undescribed species from arid habitats in southernmost and western Madagascar that is closely related to the blue-legged mantella, sometimes has been referred to as M. aff. expectata. Sex in the blue-legged mantella can be determined by the size of the body (females averaging noticeably larger than males), a horseshoe-shaped blue spot located on the lower jaw in males, and by the vocal signals that are specifically emitted only by males.

Carl Gustav Calwer (11 November 1821, Stuttgart -- 19 August 1874, Mineralbad Berg) was a German entomologist who specialised in Coleoptera. Calwers Käferbuch He wrote initially with the Stuttgart professor Dr Gustav Jäger Käferbuch, Naturgeschichte der Käfer Europas published by Julius Hoffmann, Stuttgart a 666-page work with 50 lithographic plates all but two in colour. This very popular work was successively reprinted until 1916. Many of the fine plates were reused in Georgij Georgiewitsch Jacobson's 1905 Beetles of Russia, enabling Jacobson to focus on illustrating previously undescribed species.

The Aholibah underwing (Catocala aholibah) is a moth of the "owlet" family Erebidae, which has over 25,000 known members, and more than that yet undescribed. Like other moths of the underwing genus (Catocala), this species has dull gray and black speckled forewings which help it blend into its surroundings, and bright orange underwings that it reveals to startle predators. The adults are mature during the early summer, and are found in western North America from British Columbia south to Arizona. An adult has a wingspan of up to 8 centimeters.

This is a possibility, since Réunion and Mauritius do share some types of animals, but no fossil evidence has yet been discovered. Many other endemic species of Réunion became extinct after the arrival of man and the resulting disruption of the island's ecosystem. The Mascarene parrot lived alongside other recently extinct birds such as the hoopoe starling, the Réunion ibis, the Réunion parakeet, the Mascarene grey parakeet, the Réunion swamphen, the Réunion owl, the Réunion night heron, and the Réunion pink pigeon. Extinct Réunion reptiles include the Réunion giant tortoise and an undescribed Leiolopisma skink.

It was smaller and less robust than M. platyceps. Meiolania remains are also known from the Pindai Caves, Grande Terre, and from Tiga Island. M. brevicollis was described in 1992 from the mid-Miocene Camfield Beds of northern Australia, and differed from M. platyceps in having a flatter skull and other horn proportions. A second undescribed species of Meiolania from mainland Australia is known from the Wyandotte Creek locality in Queensland, dated to the Late Pleistocene, consisting of three horn cores and a caudal vertebra, noted to be "unusually large" in size.

The Evanioidea are a small hymenopteran superfamily that includes three families, two of which (Aulacidae and Gasteruptiidae) are much more closely related to one another than they are to the remaining family, Evaniidae. The rich fossil record, however, helps fill in the gaps between these lineages. They all share the trait of having the metasoma attached very high above the hind coxae on the propodeum. It is a poorly known group as a whole, with some 1100 known species in total, and a great many species are still undescribed.

The Ceraphronidae are a small hymenopteran family with 14 genera and some 360 known species, though a great many species are still undescribed. It is a poorly known group as a whole, though most are believed to be parasitoids (especially of flies), and a few hyperparasitoids. Many are found in the soil, and of these, a number are wingless. The family is distinguished from the closely related Megaspilidae by having a very small stigma in the wing, a very broad metasomal petiole, and a single median groove in the mesoscutum.

The Megaspilidae are a small hymenopteran family with 13 genera in two subfamilies, and some 450 known species, with a great many species still undescribed. It is a poorly known group as a whole, though most are believed to be parasitoids (especially of sternorrhynchan Hemiptera), and a few hyperparasitoids. Many are found in the soil, and of these, a number are wingless. The family is distinguished from the closely related Ceraphronidae by having a very large stigma in the wing, a relatively constricted metasomal petiole, and three grooves in the mesoscutum.

These however are more likely centrosaurine; they have also been referred to Avaceratops.Penkalski, P.G., 1993, "The morphology of Avaceratops lammersi, a primitive ceratopsid from the Campanian of Montana", Journal of Vertebrate Paleontology 13(3, supplement): 52A In 1906 Richard Swann Lull noted that the name Ceratops had been preoccupied by a bird, Ceratops Rafinesque 1815, but also that this had been an undescribed nomen nudum, causing the name to have been still available in 1888. He nevertheless provisionally proposed a replacement name: Proceratops. This is thus a junior synonym of Ceratops.

The first published traces of Siwu (Akpafu) date back to the 1890s, when German missionaries and colonial officials started exploring the Hinterland of their protectorate Togoland. In an early ethnographic study of the wider area (Plehn 1898) we find what is probably the first Siwu to appear in print: two songs and a bit of vocabulary related to houses and buildings. Since then, fragments have been published here and there, but by and large Siwu remains undescribed. Early German sources besides Plehn are Seidel (1899), Funke (1920), and Westermann (1922).

Populations in California represent a complex of undescribed species that are collectively referred to as Hygrophoropsis aurantiaca sensu lato. A saprophytic fungus, H. aurantiaca obtains nutrients from forest litter and decomposing wood, causing a brown rot on the wood upon which it grows. H. aurantiaca secretes large amounts of oxalic acid, a reducing agent and relatively strong acid. This stimulates weathering of the humus layer of forest soil, and influences the solubility and turnover of nutrients (particularly phosphorus and nitrogen), which in turn affects their availability for use by forest trees.

S. stilesi and S. rodriguezi from Colombia). The taxonomic status of many of the Andean species was resolved by Krabbe & Schulenberg (1997) who split a number of species and described three new ones. The confusing situation is perhaps best illustrated by the fact that only 10 species were recognized in this genus in 1970 (Krabbe & Schulenberg, 2003), while the figure now is more than four times as high. Additionally, still undescribed species are known to exist, while some species as currently defined actually may include several species (e.g.

The flattened head of Laccognathus embryi indicates that it was a benthic sit-and-wait ambush predator. There are fossils of at least eight other vertebrate taxa found within the same fossiliferous zone as L. embryi, including Asterolepis, several large tetrapodomorphs, dipnoans, and another small undescribed holoptychiid. Though the locality in Ellesmere island is from freshwater siltstone alluvial deposits, the existence of other members of the genus in marine and estuarine deposits in Europe suggest that Laccognathus species could tolerate a wide range of environmental conditions and salinity levels.

The typically reported maximum standard length of this species is . Considerably larger individuals, up to long, have been reported from the Tocantins–Araguaia basin, but this population, together with those from the Tapajós and Xingu, likely represent an undescribed species (not to be confused with P. birindellii, a species from the Xingu basin that was described in 2018). Juvenile striped raphael catfish have been recorded cleaning piscivorous fish such as Hoplias cf. malabaricus. The stripe pattern in the young may serve as a signal that allows for its recognition as a cleaner.

Imber's petrel (Pterodroma imberi) is an extinct seabird of gadfly petrel from the Chatham Islands. The species' epithet commemorates New Zealand ornithologist Mike Imber (1940–2011). The first remains of Imber's petrel were collected in 1947 but it was not until 1967 when British ornithologist William Richard Postle Bourne considered it as undescribed and extinct species which is distinctive from other gadfly petrels bred on the Chatham Islands. Imber's petrel became apparently extinct as late as the 19th century when the first Europeans colonized the Chatham Islands and their cats preyed on the breeding seabirds.

They inhabit organic debris of all kinds and are extremely numerous in leaf litter. They feed on animals, plants and fungi and some are parasites of plants and animals. Some 48,200 species of mites have been described, but there may be a million or more species as yet undescribed. The tropical species Archegozetes longisetosus is one of the strongest animals in the world, relative to its mass (100 μg): It lifts up to 1,182 times its own weight, over five times more than would be expected of such a minute animal.

The genus Neacomys, also known as bristly mice because of their spiny fur, includes several species of rodents in the tribe Oryzomyini of family Cricetidae. It is most closely related to Oligoryzomys, Oreoryzomys, and Microryzomys.Weksler, 2006 Neacomys species are mainly found in the Amazon basin, but N. pictus occurs in Panama and N. tenuipes in montane Colombia. In Amazonia, there is a single large species, N. spinosus, and a number of smaller ones, including N. dubosti, N. guianae, N. paracou, N. minutus, N. musseri, N. rosalindae, N. macedoruizi, and various others that remain undescribed.

Wallace's flying frog or the Abah River flying frog (Rhacophorus nigropalmatus) is a moss frog found at least from the Malay Peninsula into western Indonesia, and is present in Borneo and Sumatra. It is named for the biologist, Alfred R. Wallace, who collected the first specimen to be formally identified. R. dennysii, R. maximus and Polypedates feae were once contained within Wallace's flying frog as subspecies. Similar frogs also occur in Laos, Vietnam, Malaysia, Thailand and southern China; these may be R. nigropalmatus or an undescribed, closely related species.

The genus Anelasma contains a single species, Anelasma squalicola. The nominal species, however, has a very broad distribution and may in fact be a species complex that contain several undescribed species. It has been suggested that Anelasma diverged from the ancestor it shares with its current closest relatives (the free-living, suspension-feeding species in the genera Capitulum and Pollicipes) a long time ago. The species may represent the only remaining representative of a previously more numerous clade that made the evolutionary transition from filter-feeding to parasitism.

Just as Lovecraft left his creatures undescribed, the Thing can be seen, but its shape is mostly indescribable, beyond the realm of human knowledge. Grey said that MacReady represents a more traditional Hollywood film protagonist, but Blair represents the Lovecraftian protagonist, who succumbs to his fear of the creature, is driven insane by the implications of its nature, and eventually becomes what he fears. The Thing never speaks or gives a motive for its actions, and ruthlessly pursues its goal. Grey describes the creature as fear of the loss of self.

Psylliodes luridipennis, commonly known as the Lundy cabbage flea beetle or the bronze Lundy cabbage flea beetle, is a species of flea beetle endemic to the island of Lundy, where it lives and feeds upon the endemic Lundy cabbage (Coincya wrightii). Along with the true weevil Ceutorhynchus contractus var. pallipes and an undescribed race of flea beetle Psylliodes napi, it is known only from the Lundy cabbage. The species was first recorded by Thomas Vernon Wollaston in the 1840s, and was named by the Austrian entomologist Franz Kutschera in 1864.

All Spiraxidae are thought to be carnivorous. Pittieria aurantiaca has been observed to feed on honeydew produced and ejected by Enchophora sanguinea (a lantern bug in the family Fulgoridae). This is thought to be the first known trophobiotic interaction between a gastropod and an insect. It was also observed that sometimes ants of an undescribed species in the genus Camponotus (JTL-005, JTL-005 on AntWeb, on Ants of Costa Rica) positioned themselves on the head of the snail in order to "steal" (kleptotrophobiosis) honeydew from the head of the snail.

The temple and the platform are not perfectly aligned, but there appears to have been an attempt to produce general symmetry. The surveyed architecture consisting of the temple plaza and associated platforms is apparently the core of a larger group of buildings. Investigators highlighted overgrown buildings further down the mountainside, the dimensions of which suggest another temple similar in size and design to the central temple. A small platform is located up the slope to the southeast, beside a road, and there are likely to be further remains as yet undescribed.

Skull of Pelagornis mauretanicus Apart from the giant teratorn Argentavis magnificens, the biggest of the pseudotooth birds were the largest flying birds known. Almost all"Pseudodontornis" stirtoni is the only notable exception: Scarlett (1972) contra Mayr (2009: p. 59) of their remains from the Neogene are immense, but in the Paleogene there were a number of pelagornithids that were around the size of a great albatross (genus Diomedea) or even a bit smaller. The undescribed species provisionally called "Odontoptila inexpectata"Published in a thesis and hence a nomen nudum.

Asterophysus batrachus, the gulper catfish or ogre catfish, is a species of catfish (order Siluriformes) of the family Auchenipteridae. It is native to the Rio Negro and Orinoco basins in Brazil, Colombia and Venezuela, where mostly found in slow-moving waters with many submerged structures. It is currently the only recognized species of the genus Asterophysus, but a specimen that possibly represents an undescribed species has been collected in Marajó (about from the traditionally recognized range of A. batrachus). The gulper catfish grows to a standard length of , and a total length of .

The lollipop catshark was originally described by American ichthyologist Charles Henry Gilbert as Catulus cephalus, in the 1892 14th volume of Proceedings of the United States National Museum. His description was based on a long adult male caught from a depth of off Clarion Island in the Revillagigedo Islands. In 1941, Henry F. Bigelow and William C. Schroeder created the new genus Cephalurus for this species. One or more yet-undescribed species of Cephalurus appear to exist off Panama, Peru, and Chile, which differ slightly from C. cephalus in appearance and size.

For example, in a paper describing the phylogeny of small benthic freshwater fish called darters, five undescribed putative species (Ozark, Sheltowee, Wildcat, Ihiyo, and Mamequit darters), notable for brightly colored nuptial males with distinctive color patterns, were referred to as "Etheostoma cf. spectabile" because they had been viewed as related to, but distinct from, Etheostoma spectabile (orangethroat darter). This view was supported in varying degrees by DNA analysis. The somewhat informal use of taxa names with qualifying abbreviations is referred to as open nomenclature and it is not subject to strict usage codes.

The Hutton's shearwater breeding colony at Shearwater Stream where the first black-eyed gecko was discovered. The first specimen of M. kahutarae collected was found in March 1970 in a colony of Hutton's shearwaters on Mt Tarahaka in the Seaward Kaikoura Range. It was immediately recognised as an undescribed species, but repeated searches from 1970 to 1981 in the Seaward Kaikouras failed to find any further individuals, until in 1983 four were collected in the Kahutara Saddle area, away from where it was first found. The specific epithet, kahutarae, is taken from the place where the type specimen was found.

Kleiner, 519 Hemessen is shown at half length and holding a brush, looking outwards as if at her own image as she records it on the oak panel in front of her.Most of Hemessen's surviving works show the subject seated or posing against a dark flat and undescribed background. She has only begun work on the depicted painting, no background has been put down, and only a sketch of her head can be seen. Her face is painted with soft brush-strokes, while the textures of her gown are distinguished using a wider variety of brushmarks.

The total number of undescribed organisms is unknown, but marine microbial species alone could number 20,000,000. The number of quantified species will ipso facto always lag behind the number of described species, and species contained in these lists tend to be on the K side of the r/K selection continuum. More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described. The total number of related DNA base pairs on Earth is estimated at 5.0 x 1037 and weighs 50 billion tonnes.

In May 1987, Glyn Francis, an employee at the Iron Monarch mine in South Australia, submitted for identification some mineral specimens from the mine to A. Pring. Very small, unidentified pale brownish orange crystals were seen in one specimen; study showed they had a formula of the type M5(XO4)2(OH)4 and contained manganese, phosphorus, and a minor quantity of arsenic. The powder X-ray diffraction pattern could not be recorded as insufficient material was available. Another specimen in the same group consisted of arsenoclasite crystals overgrown by what appeared to be its as yet undescribed phosphorus analogue.

It was originally extracted from Streptomyces nodosus, a filamentous bacterium, in 1955, at the Squibb Institute for Medical Research from cultures of an undescribed streptomycete isolated from the soil collected in the Orinoco River region of Venezuela. Two antifungal substances were isolated from the soil culture, Amphotericin A and Amphotericin B, but B had better antifungal activity. For decades it remained the only effective therapy for invasive fungal disease until the development of the azole antifungals in the early 1980s. Its complete stereo structure was determined in 1970 by an X-ray structure of the N-iodoacetyl derivative.

Amanita franchetii is a species of fungus in the family Amanitaceae. It was given its current name by Swiss mycologist Victor Fayod in 1889 in honor of French botanist Adrien René Franchet. A. franchetii occurs in Europe and North Africa with oaks (Quercus ssp.), chestnuts (Castanea ssp.), and pines (Pinus ssp.). Amanita augusta, formerly classed as Amanita franchetii sensu Thiers, Point Reyes National Seashore, Marin Co., California, USA A similar fungus in western North America was also referred to as A. franchetii, but was long suspected of being a separate, undescribed species, and in 2013 was formally described under the name Amanita augusta.

Perdita is a large genus of small bees native to North America, particularly diverse in the desert regions of the United States and Mexico. There are 634 currently recognized species of Perdita, plus an additional 127 subspecies and many more species that remain undescribed. Perdita are usually quite small (2.0 mm to 10.0 mm) and often brightly colored with metallic reflections and/or yellow or white markings, and among the few lineages of bees incapable of stinging. The genus was extensively treated by P.H. Timberlake who, in addition to T.D.A. Cockerell, described most of the known species.

Notable animals found here include the Djibouti spurfowl (Pternistis ochropectus), a population of green-winged pytilia that may actually be a distinct species or subspecies (Pytilia (melba) flavicaudata), as well as the mysterious and undescribed Tôha sunbird—Djibouti sunbird (Chalcomitra sp. indet.). All of these birds do not occur outside of and are endemic to Djibouti, and except for the Francolin they have only ever been found within Day Forest. More widespread birds inhabiting the forest are Gambaga flycatcher (Muscicapa gambagae), Somali bulbul (Pycnonotus (barbatus) somaliensis) and Somali starling (Onychognathus blythii). The rare colubrid snake Platyceps afarensis is also found here.

At present, the taxonomic position of the Philippines population (called hito or simply "catfish" by the locals) is unclear, and it also is unclear whether South Indian populations are C. magur or another species. As a consequence, much information (behavioral, ecological, related to introduced populations, etc.) listed for C. batrachus, may be for the closely related species that have been confused with true C. batrachus. True C. batrachus, C. magur and the two likely undescribed species are all kept in aquaculture. Walking catfish thrive in stagnant, frequently hypoxic waters, and often are found in muddy ponds, canals, ditches, and similar habitats.

Within Strabopida, the closely related Strabops thacheri exceeded the length of Paleomerus with 11 cm (4.3 in), while Parapaleomerus sinensis reached a total length of 9.2 cm (3.6 in). Like some other arthropod clades, the strabopids possessed segmented bodies and jointed appendages (limbs) covered in a cuticle composed of proteins and chitin. The arthropod body is divided into two tagmata (sections); the frontal prosoma (head) and posterior opisthosoma (abdomen). The appendages were attached to the prosoma, and although they are unknown in strabopids (except for one undescribed specimen of Parapaleomerus), it is most likely they owned several pairs of them.

Spruance sneaks the letter out on the next supply plane. The letter has an impact as some weeks later, at the height of the 24 hour darkness of the winter solstice, the Army orders a sudden and rapid shutdown of the base due to "compromised security". The same mysterious operative appears, telling Spruance by name (as they have clarified his identity) that the remaining "Guys" will be disposed of (in an undescribed way). Spruance and Teal find Guy X under his bed in the otherwise abandoned ward, and answer his request to see the outside world before he dies.

Analysis of environmental metagenomic datasets has revealed that there are other species related to C. velia and V. brassicaformis associated with corals, but yet to be described. These associations are globally distributed. Among these is the uncultured undescribed "apicomplexan-related lineage-V" which was inferred by the authors to be potentially photosynthetic, and appears to be a symbiosis specialist. Cultured chromerids by comparison can be hypothesized to move between the free-living and coral-associated states, as they are found in M. digitata eggs but are also associated with seaweed, judging from correlations in macroalgal metagenomic datasets.

Great white shark hunting strategies may be similar to how megalodon hunted its large prey. Megalodon bite marks on whale fossils suggests that it employed different hunting strategies against large prey than the great white shark. One particular specimen–the remains of a long undescribed Miocene baleen whale–provided the first opportunity to quantitatively analyze its attack behavior. Unlike great whites which target the underbelly of their prey, megalodon probably targeted the heart and lungs, with their thick teeth adapted for biting through tough bone, as indicated by bite marks inflicted to the rib cage and other tough bony areas on whale remains.

It was initially believed to be a coelurosaur due to the upturned anterior process of the postorbital as well as specialized teeth which are unserrated on the mesial (front) side and have an 8-shaped cross section, similar to those of dromaeosaurids and compsognathids. However, many other features contradict those of these families and other coelurosaurs, so its original describers were unable to conclusively assign it to any specific family. They did note its similarity to a then-undescribed Patagonian theropod now known as Murusraptor. More recent analyses have explained that these coelurosaur-like traits are also present in some megaraptorans.

On her return to the department of zoology with University of Leicester in 1971 she noticed the huge number of insects in her garden in the United Kingdom compared to those in Africa and the study began. Owen achieved the recording of ninety-one of the 256 species of hover flies in Britain in fourteen years. in thirty years of study she recorded 2,204 insect species in her own garden while also finding 20 species new to Britain and six which were previously undescribed. She wrote a book on the study, Wildlife of a Garden: A Thirty-Year Study.

This was therefore an important early collection for the genus, only seven species of which had previously been collected. Menzies' seed specimens were sent to England from Sydney in 1793, but his plant material remained with him for the duration of the voyage, during which some material was lost. On his return to England in 1795, the surviving specimens were deposited into the herbarium of Sir Joseph Banks, where they lay undescribed for many years. The next collection was made in December 1801, when King George Sound was visited by HMS Investigator under the command of Matthew Flinders.

Thoracochromis is a fish genus of haplochromine cichlids that are endemic to Africa. Most species are from rivers in Angola and Namibia, or the Congo River Basin in Central Africa, but T. wingatii is from the Nile system. Additionally, there are a few apparently undescribed species from the Nile system (two in its delta and one from lakes near Fayum), which appear to be close relatives of T. wingatii or Haplochromis loati. Many species have been moved between this genus and Haplochromis, and while some consensus has been reached in recent years, their mutual delimitation is still far from settled.

Examination of the protease gene (SERA) in 18 species has shown that the ancestral state had only a single gene and that gene duplications have occurred in the extant species. This paper confirms the groupings found elsewhere with an Asian clade. The rodent species seem to be more closely related to the Laverania subgenus than does the subgenus Plasmodium. A deletion mutation of ~100 base pairs including part of the LS1 rRNA gene is found in the sequences of two African species - P. gonderi and an undescribed parasite taken from a mandrill - and 2 Asian species - P. cynomolgi and P. simiovale.

Rhinochelys nammourensis In 1888, the Belgian zoologist George Albert Boulenger published his classification of the Testudinata within the 9th edition of the Encyclopædia Britannica. The genus Protostega was placed within the family Sphargidae under the suborder Athecae. A year or so later, the entire suborder was downgraded by Karl Alfred von Zittel into a family within the Cryptodira. In 1994, Hirayama proposed a three-family subdivision of the sea turtle superfamily based on cladistic analysis; Protostegidae was given full, formal family status in the system, containing most of the extinct genera, including Archelon, and a previously undescribed protostegid.

Sparganophilus, the only genus in the family Sparganophilidae, is a group of long, slender, limicolous (mud-dwelling) earthworms native to North America. The number of species is unknown, most of them are undescribed, throughout the continent and into Central America. One species, S. tamesis, has been introduced into the streams of Europe, where it is now widespread; its synonyms are S. eiseni, S. benhami, S. guatemalensis, S. carnea, S. elongatus, S. cuenoti and, newly, S. langi.Earthworms (Sims & Gerard, 1999: 120 ) Sparganophilidae checklist (2007)Cosmopolitan Earthworms (Blakemore, 2008) Sparganophilus species are characterised by a simple gut with no gizzard and no typhlosole.

The severe reduction in range has resulted in the species' listing as a federal and state species of concern. The masked duskysnail (Lyogyrus) and Washington duskysnail (Amnicola), both undescribed species, are found in only two glacial kettle lakes in Washington, Fish Lake in Okanogan County and Curlew Lake. Believed to have formerly ranged in glacial lakes from the Cascades to the Rockies, the Washington duskysnail is now only found in one location outside of Washington, and both snails are limited to the two lakes in Washington. This isolated range has placed them on state and federal watchlists as critically imperiled species.

A rounded earth star (Geastrum saccatum), in Mount Field National Park, Tasmania Native species are very poorly known, with most taxa undescribed. For those that have been, there are huge gaps in knowledge, especially with respect to distribution and, for the larger species, edibility. Reasons for this include the brief and unpredictable appearance of fruiting bodies, often the only evidence of most species, and the fact that there has been comparatively little scientific attention focused upon fungi in Australia. There are several exceptions; one is the family Hygrophoraceae, which has been written about by mycologist A. M. (Tony) Young in 2005.

Wood's cycad at the Durban Botanic Gardens, once endemic to oNgoye Forest This relict patch of transitional Afromontane-coastal forest is home to rare and endemic species. It was home to the giant Wood's cycad which is extinct in the wild since the early 1900s, but the oNgoye dwarf cycad, Ground cycad and Natal grass cycad still occur. It is home to the endemic race ornatus of the Red bush squirrel, the endemic race woodwardi of Woodward's barbet, two undescribed dwarf chameleons similar to the Qudeni dwarf chameleon,Tolley, K. and Burger, M. 2007. Chameleons of Southern Africa.

It was coined as a reference to both Vlad's preferred execution style and for his inspiration of Bram Stoker's Count Dracula, who drank blood. The three remaining workers studied, BuPH-02, BuPH-03, and BuPH-04 were assigned to Linguamyrmex due to several factors. Each of the specimens is incomplete, all missing portions of the antennae, making comparison of the scape length to the other segments impossible, and all specimens are missing the terminal segments of the gaster. Based on the worker size and on paddle composition Barden and Grimaldi suggest the three workers may belong to undescribed species.

Walkerana muduga, also known as the Muduga mountain leaping frog or Muduga leaping frog, is a species of frog in the family Ranixalidae. It is endemic to the Western Ghats of India and known from the Elivai Malai range, north of the Palghat Gap in Tamil Nadu. All other known species of Walkerana occur south of the Palghat Gap, and molecular data suggest that Walkerana muduga is deeply divergent from the more southern species. However, there is another, as yet undescribed lineage from north of the Palghat Gap that is known from a single, poorly preserve specimen.

The species was first described scientifically by Melissa Danks, Teresa Lebel, and Karl Vernes in a 2010 issue of the journal Persoonia. The type collection was made in Mount Kaputar, New South Wales (Australia) in July 2007. Molecular analysis of internal transcribed spacer DNA sequences indicates that Cortinarius cinereoroseolus groups together in a subclade with two undescribed sequestrate Cortinarius species, and that this subclade is sister to a clade containing the agaric species C. australis, C. chalybaeus, C. porphyropus, C. purpurascens and C. purpurascens var. largusoides; all of these species belong to the section Purpurascens of the genus Cortinarius.

However, in a 1986 paper, an Emory professor Dr. Besharse and his team, suggested that the distinction between the processes of disc detachment and phagocytosis was made ambiguous by the observation of pigment epithelial processes intruding into the OS during disc detachment. They documented the ultrastructural changes that occur within the photoreceptor OS and the RPE during photosensitive membrane turnover. They induced shedding in Xenopus laevis by adding the excitatory amino acid L-aspartate. They found that during L-aspartate-induced shedding, the RPE cells formed, on their apical domains, previously undescribed processes that were directly involved in disc phagocytosis.

The blackstripe corydoras or Bond's catfish (Corydoras bondi) is a tropical freshwater fish belonging to the Corydoradinae sub-family of the family Callichthyidae. It originates in inland waters in South America, and is found in the Yuruarí River in Venezuela and the Corantijn and Rupununi River basins in Guyana and Suriname. In the system of "C-Numbers" developed by the German fishkeeping magazine DATZ to identify undescribed species of Corydoras in the aquarium hobby, this fish had been assigned number "C31" until it was correctly identified. The fish will grow in length up to 1.9 inches (4.7 centimeters).

The pied monarch was described by John Gould in 1851, who deliberated on placing it in a genus by itself on account of its feet and eye ring. The nest and eggs were undescribed until collected by Robert Hislop on 3 December 1894 near Bloomfield River. Illustration by John Gould The pied monarch is closely related to and forms a superspecies with the two other species of monarch flycatcher in the genus Arses. Two subspecies are recognised, however they two intergrade where their ranges meet at Mossman, and they could be treated as a monotypic species.

The Chiapas catfish, Lacantunia enigmatica, is an unusual species of catfish (order Siluriformes) newly described in 2005 from the Lacantún River in the Mexican state of Chiapas. While discovery of an undescribed species of catfish is not uncommon, discovery of a new family-level taxon of any vertebrate group is a rare event. The Chiapas catfish mainly feeds on crabs, prawns, small fish, and large, tough plant seeds. This catfish is commonly fished in its natural habitat, where it is known as madre de juil, which means "mother of Rhamdia" (a common fish in the area).

Elsewhere on the more exposed, elevated sites, a range of low stature communities exists. Low woodland and tall shrubland of snowgum merges with open heathland of common shaggy pea Oxylobium ellipticumand alpine plum pine Podocarpus lawrencii and swamp heath of Epacris paludosa within polsters of Sphagnum christatum. In the lower depressions, often fringed by stands of black sallee Eucalyptus stellulataare snowgrass herbfields (dominated by Poa spp.) and sedgelands or Carex fens typified by the occurrence of Carex gaudichaudiana. Notable plant species occurrences include that of two rare or vulnerable shrubs, Australian anchor plant Discaria pubescensand an undescribed daisy bush (Olearia sp.

In 1996, Geise and coworkers described a new karyotypic variant of Calomys from Lagoa Santa, Minas Gerais with 36 chromosomes and a fundamental number of 66 autosomal arms (2n = 36, FNa = 66), and a 2007 genetic analysis confirmed that the new variant represents an evolutionary lineage separate from other Calomys species.Bonvicino et al., 2010, pp. 19, 28 In 2010, Bonvicino and others described another karyotypic variant from Capitão Andrade, also in Minas Gerais, with 2n = 38 and FNa = 66, and concluded that both karyotypic variants represented a single, previously undescribed species, which they named Calomys cerqueirai.

Steere attended medical school at the Columbia College of Physicians and Surgeons, and graduated in 1969. After internship and residency, he spent two years in the Epidemic Intelligence Service of the Centers for Disease Control in Atlanta and was sent around the country to evaluate outbreaks of disease. In 1975, four months after starting his rheumatology fellowship at Yale University, he learned of a cluster of children who were thought to have juvenile rheumatoid arthritis in Lyme, Connecticut. Evaluation of the case clusters suggested that this was a tick-borne illness and a previously undescribed type of arthritis.

The Pinocchio frog or northern Pinocchio treefrog (Litoria pinocchio) is a species of frog in the family Pelodryadidae. It was discovered in the Foja Mountains of Papua Province in Indonesia by Conservation International and the National Geographic Society during a 2008 expedition, where it was accidentally spotted by Paul Oliver, a herpetologist. Despite being discovered in 2008, it remained undescribed and was long known simply as the "Pinocchio frog" (with no given scientific name) until 2019, when it was finally described as Litoria pinocchio. The frog is named for its Pinocchio-like nose, which can enlarge and inflate in certain situations.

Hapuakohe ranges. Kopuatai is one of only three sites to contain the plant Sporadanthus ferrugineus a formally widespread but now rare peatforming plant found only in the upper north island of New Zealand. S. ferrugineus in turn provides the only known food source for a rare endemic moth Houdinia flexilissima known as 'Fred the thread' described as recently as 2006 and remarkable for being the thinnest caterpillar in the world a number of other undescribed insect species are thought to inhabit the peat dome. Other plant species found at Kopuatai are the peat-forming plant Empodisma robustum and the fern Gleichenia dicarpa.

Around 220 described species, and more undescribed species of ants in the tribe Attini cultivate fungi. They are only found in the New World and are thought to have evolved in the Amazon Rainforest, where they are most diverse today. For these ants, farmed fungi are the only source of food on which their larvae are raised on and are also an important food for adults. Queen ants carry a small part of fungus in small pouches in their mouthparts when they leave the nest to mate, allowing them to establish a new fungus garden when they form a new nest.

Diplotaxodon is a small genus of seven formally described, as well as a number of undescribed, deep-water species of cichlid fish endemic to Lake Malawi in east Africa. These fishes represent a remarkable adaptive radiation of offshore and deep-water adapted fish descended from ancestral shallow water forms. They include the dominant zooplankton-feeding fish of the offshore and deep-water regions of the lake, as well as a number of larger species that appear to feed on small pelagic fishes. Adult sizes range from 10 to 30 cm in total length, depending on species.

In 1999, Carpenter and colleagues described material of a large nodosaurid from Utah, discovered in a member of the Cedar Mountain Formation called the Poison Strip Sandstone, which is contemporaneous with the Cloverly Formation. He originally referred it to Sauropelta as a possible new species, but it was never named. In more recent publications, Carpenter no longer refers the Poison Strip animal to Sauropelta, only to the family Nodosauridae. Armor plate Other recent, but undescribed, discoveries include a complete skull from the Cloverly of Montana and a huge fragmentary skeleton from the Cedar Mountain Formation of Utah.

The new specimen also showed no sign of the nuchal crest, indicating that the crest inferred from the holotype specimen may be an artifact of taphonomic distortion. Numerous further specimens likely belonging to Microraptor have been uncovered, all from the Shangheshou Bed of the Jiufotang Formation in Liaoning, China. In fact, Microraptor is the most abundant non-avialan dinosaur fossil type found in this formation. In 2010, it was reported that there were over 300 undescribed specimens attributable to Microraptor or its close relatives among the collections of several Chinese museums, though many had been altered or composited by private fossil collectors.

The pitta-like ground roller is endemic to the eastern half of Madagascar, from the extreme north to the southern edge, and has the widest distribution of any member of the family. It also has a wider range of habitats that it is prepared to occupy, being found in all natural rainforest types on the island from sea-level to , although it is commonest between . It can also appear in smaller numbers in degraded secondary forest. It is generally non-migratory but changes in numbers linked to the weather have been noted so some undescribed movements may be happening.

The Mekong freshwater stingray was first recognized as a new species by Yasuhiko Taki, who included it as "Dasyatis sp." in his 1968 list of Mekong River fishes from Laos. Taki's specimens were subsequently lost, and this ray was not formally described until 1987, by Tyson Roberts and Jaranthada Karnasuta, in the scientific journal Environmental Biology of Fishes. The type specimen is an immature male across, caught from the Mekong in Chiang Rai Province, Thailand. A 1999 phylogenetic analysis, based on cytochrome b sequences, found that the Mekong freshwater stingray is closely related to an undescribed dasyatid species from the Gulf of Thailand.

"Coelurosaurus" is an informal generic name, attributed to Friedrich von Huene, 1929, that is sometimes seen in lists of dinosaurs. It probably arose as a typographical error; von Huene intended to assign indeterminate remains to Coelurosauria incertae sedis, but at some point in the process of publication a revision to the text made it appear that he was creating a new generic name "Coelurosaurus" (as described by George Olshevsky in a 1999 post to the Dinosaur Mailing List). The name is undescribed and has not been used seriously, although it has appeared in works of fiction.

It has also been given the moniker of "living fossil" for being part of the family Cryptobranchidae which dates back 170 million years. It is one of only four to five known extant species of the family, the others being the slightly smaller, but otherwise very similar Japanese giant salamander (Andrias japonicus), the slightly larger South China giant salamander (A. sligoi), an undescribed species from eastern China, and the far smaller North American hellbender (Cryptobranchus alleganiensis).Browne, R.K.; Li, H.; Wang, Z.; Okada, S.; Hime, P.; McMillan, A.; Wu, M.; Diaz, R.; McGinnity, D.; & Briggler, J.T. (2014).

The family Mantellidae is composed of three extremely ecologically diverse groups of frogs, divided into three subfamilies: the Mantellinae Laurent, 1946 are typically terrestrial or semi-aquatic frogs; the Laliostominae Vences & Glaw, 2001 are terrestrial, typically fairly large-sized frogs; and the Boophinae Vences & Glaw, 2001 are arboreal tree frogs. Apart from the genera assigned to the three subfamilies, the placement of Tsingymantis Glaw, Hoegg & Vences, 2006 is still uncertain. As of the 3rd of May 2016, 212 species are recognized in this family. DNA barcoding research has shown however that more than 100 distinct genetic lineages remain taxonomically undescribed.

Less closely related is the Robertson dwarf chameleon, another aridland species which is found in Western Cape province inland from the range of the Cape dwarf chameleon and may be a cryptic species complex, and an undescribed population from the Swartberg Mountains.Branch (1998): plate 1, Tolley et al. (2004) The last species with aridland apomorphies, the Namaqua dwarf chameleon, is quite distant to the others; it occurs in coastal regions from north of the Cape species through Namaqualand. This is probably still a part of a single radiation which brought about all the aridland taxa, and eventually Smith's dwarf chameleon.

Neither T. japonicus nor T. nitens are recognized as separate species by FishBase where considered synonyms of T. lepturus, but they are recognized as separate species by the Catalog of Fishes. The IUCN recognizes the East Atlantic population as a distinct, currently undescribed species. This is based on genetic evidence showing a divergence between West and East Atlantic populations. However, this would require that T. japonicus, T. nitens and the Indo-Pacific populations also are recognized as separate species, effectively limiting T. lepturus to the West Atlantic (contrary to IUCN), as they all show a greater divergence.

Reports of who first discovered B. rosserae are somewhat contradictory. Peter Olde and Neil Marriott acknowledge Ann Pilkington of Kirkalocka, "who discovered Banksia rosserae and who drew it to our attention through various third parties." However, Kevin Collins states that it was first discovered in September 2000 by a Grevillea enthusiast named John Cullen. According to Collins, Cullen had visited Kirkalocka in search of an undescribed Grevillea species mentioned in the writings of Charles Gardner (now published as G. kirkalocka); in addition to finding the Grevillea, he also found two B. rosserae plants growing on the top of an orange sand dune.

A typical habitat in Pirin The ichthyofauna includes 6 fish species: common minnow, European eel (considered extinct), western vairone, brown trout, rainbow trout and brook trout. The limited number of species is determined by the high altitude of the park. The glacial lakes, streams and upper river courses are inhabited by few fish species. The western vairone is known only from the Kremenski lakes and might in fact represent a new undescribed species. The number of identified invertebrate species in Pirin National Park is 2091, which is 40% of the estimated 4500 species to inhabit the park.

Undescribed species, and those not previously recorded in New Zealand, continue to be found in lowland forests. Ninety species and varieties are listed on the 2001 Department of Conservation threatened plants list, and 157 liverwort species and varieties will be included on the next version of the list as a result of better knowledge of the group. A three-volume work on liverworts in New Zealand is being written by John Engel and David Glenny, with the first volume published in 2008.Engel, J. J. and Glenny, D. 2008 A flora of the liverworts and hornworts of New Zealand.

The large Mindoro forest mouse is the third known rodent endemic to Mindoro, after the Mindoro black rat and the Mindoro climbing rat, and not including the Ilin Island cloudrunner, the occurrence of which has not been confirmed on the island. However, in a compilation work on the indigenous mammals of the Philippines, published in 1998, it was announced that there is a second Apomys on Mindoro. This species has yet to be described and has temporarily been given the name of "Apomys sp. E". It may be related to two other undescribed species from Sibuyan Island and Greater Negros-Panay, Apomys sp.

These trees are important components of the native tropical forests of their range, such as New Guinea, the lowland New Caledonia rain forests and the tropical forests of northern Australia. In this region more than forty different species grow naturally, from the lowlands to the mountains. In New Guinea D. enantiophyllum and an undescribed taxon have records of growing up to about altitude. In the forests of the region of China, India, Sri Lanka and the adjacent Himalayas including Bhutan and Nepal, about fourteen recorded different species grow naturally from the lowlands to the mountains up to altitude.

The research behind the Carbon Mineral Challenge is based on a type of analysis called Large Number of Rare Events (LNRE) modeling. To arrive at their total of 145 previously undescribed carbon minerals, Hazen and his colleagues, including mathematician Grethe Hystad of Purdue University-Calumet, focused on diversity-distribution relationships of the 403 known carbon-bearing minerals. Using 82,922 pieces of data about mineral species and localities, tabulated in mindat.org (as of 1 January 2015), the researchers found that all carbon-bearing minerals, as well as subsets containing carbon with hydrogen, calcium, sodium, or oxygen, conform to LNRE distributions.

"Coelurosaurus" is an informal generic name, attributed to Friedrich von Huene, 1929, that is sometimes seen in lists of dinosaurs. It probably arose as a typographical error; von Huene intended to assign indeterminate remains to Coelurosauria incertae sedis, but at some point in the process of publication a revision to the text made it appear that he was creating a new generic name "Coelurosaurus" (as described by George Olshevsky in a 1999 post to the Dinosaur Mailing List). The name is undescribed and has not been used seriously, although it has appeared in works of fiction.

The expedition recovered amber from the beaches of the Okhotsk Sea at the mouth of the Naiba River and upstream on the banks of the river eroding out of exposures of Naibuchi Formation strata. One additional fossil has been reported from Bitterfeld amber, and has been listed by Dlussky and Rasnitsyn 2009 as undescribed. Sakhalin amber is noted for having undergone high temperatures and pressures after the resin was buried. As a result, insects and other inclusions in the amber are not as well preserved as those of other amber locations, even those of older ambers.

In 1965 Philippe Taquet discovered the remains of an ornithopod in rock layers of the Elrhaz Formation, in the Tenere desert of Niger, it consists of a partial skeleton with a fragmentary skull belonging to single individual which was given the catalogue number GDF 1700, the remains sat undescribed until 1988 when paleontologist Souad Chabli coined the name "Gravisaurus tenerensis" in her unpublished dissertation on the animal,Chabli, S., 1988, Étude anatomique et systématique de Gravisaurus tenerensis n. g., n. sp. (Dinosaurien, Ornithischien) du gisement de Gadoufauoua (Aptien du Niger). Ph.D. dissertation, Université de Paris VII.

Caridina spongicola is a small species of freshwater shrimp from Sulawesi (Indonesia) that reaches in length. In the wild it strictly lives on an undescribed species of freshwater sponge, making it one of only two known commensal species of freshwater shrimp (the other is a Limnocaridina shrimp that lives in mussels in Lake Tanganyika, East Africa). It is popularly known as the harlequin shrimp, and also sometimes Celebes beauty shrimp or sponge shrimp in the aquarium trade. It is often confused with Caridina woltereckae, a larger and more contrastingly colored species found in the same region as C. spongicola.

The other three species separated later from each other and are thus partially compatible to each other. A. ferreum and A. laevigatum produced in 59% of all cases a common mycelium, A. ferreum and A. chailletii only in 44%. There is an undescribed species in Amylostereum; according to DNA analysis, it stands between A. laevigatum and A. ferreum. This is remarkable, as these fungi originated from Mycetangae (storing organs of Platypodinae) of a North American wood wasp, while A. laevigatum has never been seen as symbiont of wood wasps, neither in North American nor in Europe.

The Montezuma swordtail is one of nine species of swordtail found only in the Pánuco River basin The Pánuco River basin is rich in fish. There are almost 100 fish species, including a few that were introduced. There are many endemics: six Nosferatu cichlid species, five Tampichthys minnows, nine "northern swordtails" (genus Xiphophorus), three Gambusia species, two Ictalurus catfish, the bluetail goodeid (Ataeniobius toweri), dusky splitfin (Goodea gracilis), relict splitfin (Xenoophorus captivus), pygmy shiner (Notropis tropicus), checkered pupfish (Cualac tessellatus), broadspotted molly (Poecilia latipunctata), Tamasopo cichlid (Herichthys tamasopoensis), Calabazas shiner (Notropis calabazas) and fleshylip buffalo (Ictiobus labiosus). Additionally, a couple of still- undescribed species are known from this river basin.

Oxycraspedus, apparently the most ancient living genus of Oxycorynini, has three described species limited to Chile between the Maule and Araucanía Regions and adjacent Argentina where they have been found in Neuquén Province. Parallocorynus with one and Rhopalotria with three described species - several undescribed species are known in each genus - occur across Central America and in some adjacent regions. The former only occurs in Mexico and Honduras, while the latter is widespread from Mexico to Panama, also occurring on Cuba and in Florida, and probably in northern South America too. The two Alloxycorynus species are found from southern Peru (Cusco Region) to eastern Bolivia and northern Argentina.

Previously, Glen Rose crocodylomorph fossils had been known under the informal designation of the "Glen Rose Form". Fossils known under this name include a skull at the National Museum of Natural History and two partial skeletons at the Texas Memorial Museum, along with isolated bones. With the description of Pachycheilosuchus, it appears that the "Glen Rose Form" had been chimeric; the skull and the two skeletons lack the lipped jaw and procoelous vertebrae, and so are not Pachycheilosuchus but an undescribed form, but at least some of the isolated remains are Pachycheilosuchus. Thus, there were at least two crocodylomorphs in the Glen Rose Formation.

John Lanzendorf paleoart prize In 2009, he was invited by the Chinese Institute of Vertebrate Paleontology and PaleoanthropologyChinese Institute of Vertebrate Paleontology to visit their Beijing Museum and also the new Museum and fossil sites at Hezheng in central China, where he made first-hand observations of undescribed carnivore fossils. Between 2009-2010 he contributed to the "Extreme Mammals" expositionExtreme Mammals of the American Museum of Natural History, New York. In recent years, Antón is leading art safaris to Northern Botswana under the title "Drawing the Big Cats", sharing first-hand sightings and his experience in studying the anatomy and evolution of felids with artists from all around the world.

The arthropod body is divided into two tagmata (sections); the anterior prosoma (head) and posterior opisthosoma (abdomen). The appendages were attached to the prosoma, and although they are unknown in strabopids (except for one undescribed specimen of Parapaleomerus), it is most likely they owned several pairs of them. Although the chemical composition of the strabopid exoskeleton is unknown, it was probably mineralized (with inorganic substances), sturdy and calcareous (containing calcium). The head of the strabopids was very short, the back was rounded and lacked trilobation (being divided into three lobes), the abdomen was composed by 11 segments and was followed by a thick tail spine, the telson.

This specimen was later named as "Borchgrevinkium sp.". In 2017, the British geologist and paleobiologist James C. Lamsdell and the Irish palaeontologist Derek Briggs found that this specimen was YPM IP 300790, collected in the Bertie Formation in the state of New York in 1967 by Samuel J. Ciurca Jr., who identified it as a new undescribed species of Borchgrevinkium after contacting Størmer. Nevertheless, since this specimen was misidentified, it was redescribed as a new species of the chasmataspidid Diploaspis, D. praecursor, by Lamsdell and Briggs. The history of Borchgrevinkium soon became turbulent, being classified as a xiphosuran in 1989, and back to Eurypterida years later.

Chrysaora hysoscella, the compass jellyfish, is a common species of jellyfish that inhabits coastal waters in temperate regions of the northeastern Atlantic Ocean, including the North Sea and Mediterranean Sea. In the past it was also recorded in the southeastern Atlantic, including South Africa, but this was caused by confusion with close relatives; C. africana, C. fulgida and an undescribed species tentatively referred to as "C. agulhensis". It is a true jellyfish displaying radial symmetry with distinct brown markings shaped like elongated V's on its bell. C. hysoscella adults are highly susceptible to the parasite Hyperia medusarum but this hasn't had any significant effects on the population.

Blepharidatta is a strictly Neotropical group that was described by Wheeler (1915) from workers of Blepharidatta brasiliensis collected near Belém (State of Pará, Brazil), in the Amazon forest. Up to seven species are currently recognized, but most of them are waiting for a formal taxonomic treatment or confirmation. Based on morphological as well as behavioral data, only three species are formally recognized: B. brasiliensis found in the Amazonian forest, Blepharidatta conops, an inhabitant of savanna-like formation from central Brazil (Cerrado), and an undescribed species (Blepharidatta "sp-ba")Informal name used by Pereira et al. (2014) known from the Atlantic rainforest of the State of Bahia, eastern Brazil.

It is the earliest representative of Megapaloelodus, living from the Late Oligocene to the Middle Miocene, and has been found in a wide range of Central European localities, from France to Southern Germany (Ringingen-Frontal 1) and on to the Czech Republic and Hungary; it dwelled in the wetlands created by the rerouting of rivers due to the beginning uplift of the Alps. Fossils referrable to this genus have also been found in the Huayquerian Ituzaingó Formation, Argentina. At least two additional undescribed species await description pending availability of more material. Fossils have also been found in the Almejas Formation of Baja California, Mexico.

Majors for this possibly rare species could not be found and thus remain undescribed. Pheidole loki is most probably closely allied to P. jonas and P. vulcan and characterized by reduced sculpture and an intermediate amount of standing hairs, compared to these two species. Overall it resembles P. jonas more than P. vulcan, at least in habitus, morphometric measurements, and promesonotum and postpetiole shape. The minor workers of P. jonas, however, display a more strongly punctate sculpture, less abundant and less flexuous standing hairs, and on average slightly shorter scapes than P. loki, the postpetiole on average as long as wide versus longer than wide in P. loki.

These are defined by gradients of water temperature, nutrients, dissolved gases, salt concentrations etc. Along the path of terrestrial water flow the resulting temperature gradient continuum alone may provide many different minute microecosystems, starting with thermophilic bacteria such as Archaea "Archaebacteria" (100+ °C), followed by conventional thermophiles (60–100 °C), cyanobacteria (blue-green algae) such as the motile filaments of Oscillatoria (30–60 °C), protozoa such as Amoeba, rotifers, then green algae (0–30 °C) etc. Of course other factors than temperature also play important roles. Hot springs can provide classic and straightforward ecosystems for microecology studies as well as providing a haven for hitherto undescribed organisms.

Gerp's mouse lemur (Microcebus gerpi) is a species of mouse lemur known only from the Sahafina Forest in eastern Madagascar, near Mantadia National Park. Its discovery was announced in 2012 by a German and Malagasy research team. The Sahafina Forest had not been studied until 2008 and 2009, when Groupe d'Étude et de Recherche sur les Primates de Madagascar (GERP)—a Malagasy-based research and conservation group for which the lemur is named—inventoried the forest's lemurs. Based on genetic studies, measurements, and photos, the research team confirmed the Gerp's mouse lemur was an undescribed species, distinct from Goodman's mouse lemur, which is found away.

This result is well above the barcoding gap of 3.2% for Carychiinae, which is suitable to separate between species (> 3.2%, interspecific) and within species genetic diversity (< 3.2%, intraspecific) in Zospeum. Zospeum tholussum closely resemble Zospeum amoenum morphologically, but can be readily distinguished by the dome-like shape of their second whorls and by the presence of a slight fold in the central column of the shells. They can also be readily separated by means of their DNA barcodes (11.7% to 12.1% genetic p-distance between the two species). Lukina jama–Trojama also contains a second yet undescribed species of Zospeum, also recovered by the 2012 expedition.

Neogoveidae occur in tropical regions between 10° north and 5° south of the equator in both South America and West Africa, with the exception of Metasiro, which is found in southeastern United States. Current research suggests that the diversity of neotropical Neogovidae is much higher than currently known, as new species were found at virtually every place where samples were taken. Currently, the greatest amount of known Neogoveid diversity is known from Colombia, although it is unknown if this reflects greater ecosystem diversity or greater sampling efforts in that country. It is thought that Neogoveidae possesses a considerably large amount of undescribed diversity compared to most other Cyphophthalmi families.

Spinosaurine pelvis and sacral vertebrae (specimen MN 4819-V), National Museum of Rio de Janeiro Besides the skull, the snout fragment, and some isolated teeth, the Romualdo Formation has also yielded l remains that may belong to spinosaurids, many of which are hitherto undescribed, and all of them pertaining to the Spinosaurinae subfamily. In 2004, parts of a spinal column (MN 4743-V) were unearthed at the formation. Brazilian paleontologist Jonathas Bittencourt and Kellner assigned these, due to their structure, to the Spinosauridae. It is uncertain whether this specimen can be referred to Irritator or Angaturama, given that both are based only on skull material.

The following are incomplete lists of mammals, birds, fish, and invertebrate species and genera included in the Riversleigh fauna, according to the compilation of taxa by researchers at the University of New South Wales and Queensland (wakaleo.net). A survey of species-level taxa described in the Riversleigh Fauna in the decades of research preceding 2006, resulted in a total greater than 290 species. The fauna of Riversleigh includes placental mammals, especially bats, and the various families of marsupials. Due to the novelty of some taxa discovered in the area, some species have been placed in tentative arrangements or unknown lineages placed as sometimes undescribed higher taxa.

Imagines of Conogethes resemble in their wing pattern those of Marwitzia, the Polygrammodes eleuata species complex and Syllepte incomptalis, and to a lesser degree Dichocrocis, Notarcha and Trigonobela. The polyphagous Conogethes punctiferalis is a major pest species in India, Southeast Asia and Australia and has therefore been the focus of extensive research. In several cases, populations of C. punctiferalis associated with different hosts were found, eventually resulting in the recognition of different species, such as C. parvipunctalis, C. pinicolalis and C. sahyadriensis. DNA barcoding data indicates several additional undescribed species, and a comprehensive taxonomic revision of the genus is required to unravel the validity and circumscription of these new species.

Study for Portrait II, 1955. Tate Britain, London Study for Portrait II (subtitled after the Life Mask of William Blake) is a small 1955 oil on canvas painting by the Irish-born British figurative artist Francis Bacon, one of a series of six portraits completed after viewing that year the English poet, painter and printmaker William Blake's (b. 1757) life mask at the National Portrait Gallery in London. The series resembles Bacon's late 1940s and early 1950s paintings of single bust length single male figures set against anonymous flat undescribed dark backgrounds, and can thus be viewed as extensions of his "Man in Blue" paintings of a few years earlier.

The seven species of pademelons or scrub wallabies (genus Thylogale) of New Guinea, the Bismarck Archipelago, and Tasmania are small and stocky, with short hind limbs and pointed noses. The swamp wallaby (genus Wallabia) is the only species in its genus. Another wallaby that is the only species in its genus is the quokka or short-tailed scrub wallaby (genus Setonix); this species is now restricted to two offshore islands of Western Australia which are free of introduced predators. The seven species of dorcopsises or forest wallabies (genera Dorcopsis (four species, with a fifth as yet undescribed) and Dorcopsulus (two species)) are all native to the island of New Guinea.

Autapomorphies of Jiangchangnathus include: a convex top margin of the lower jaw; a large front branch of the jugal; and the first three pairs of teeth of the lower jaws pointing strongly forwards. Its describers found it to share several features with Scaphognathus, including a high front end of the lower jaws, a pear-shaped lower temporal fenestra with the broad end below and teeth in the maxilla of the upper jaw that have a space equal to that of three toothsockets between them. Additionally, undescribed fossils of a pterosaur referred to Jianchangnathus suggest that the color of its pycnofibers was brown.Li, Q., J.A. Clarke, K.-Q.

These abilities are important because larvae compete with each other to gain food, a situation which is different from all other bees, where individual larvae are isolated in cells and do not have to compete with each other. There are over 300 described species of allodapine bees, but many more species are undescribed. They are unique among bees in progressively rearing their larvae in undivided tunnels, so that individual larvae are not physically isolated from each other and are in constant contact with adult females, who provide them with food, groom them, and remove their faeces. Allodapine bees vary greatly in their forms of sociality, from subsocial to highly eusocial.

Recent studies are marked by the number of species they have involved that have not been formally described (refs). This suggests that there is a large amount of allodapine diversity that is not covered by formal scientific taxonomy. Conservation concerns centre on two regions: (i) large-scale habitat loss in Madagascar poses a major threat to that island's unique bee fauna, including allodapine bees, many of which are still to be scientifically described; and (ii) the Australian region is likely to contain many undescribed socially parasitic species which are threatened because of their very small populations sizes. Conservation threats to allodapine bees in Asia have not been studied.

The Ulanga Valley is characterized by its large populations of large mammals such as the buffalo, elephant, hippopotamus, lion, and puku. The majority of the world's Puku population live in the Ulanga Valley. The Ulanga Valley is home to one of the largest populations of Nile crocodile in Africa and is an important breeding ground for bird species such as the African openbill, white-headed lapwing, and the African skimmer. The Ulanga Valley is also home to a number of species only found in the Valley, such as the Udzungwa red colobus monkey and three species of birds, the Ulanga weaver and two undescribed species of cisticolas.

Australian ichthyologist Gilbert Percy Whitley originally described the western shovelnose stingaree as Urolophus (Trygonoptera) mucosus in a 1939 volume of the scientific journal Australian Zoologist, based on a specimen collected from King George Sound off Albany, Western Australia. Subsequent authors have recognized Trygonoptera as having full generic status. This species is closely related to the recently described T. galba and T. imitata, with which it forms a species complex that may include additional undescribed species; one example is a form found off Perth that resembles T. mucosa but is much larger, reaching a length of . (invalid, listed in publication) Other common names for this ray include kejetuk, bebil, and western stingaree.

Undescribed fossil specimen at the Hong Kong Science Museum Cast of the skeleton belonging to GMV 2124, which is probably not a Sinosauropteryx Despite its feathers, most palaeontologists do not consider Sinosauropteryx to be a bird. Phylogenetically, the genus is only distantly related to the clade Aves, usually defined as Archaeopteryx lithographica plus modern birds. The scientists who described Sinosauropteryx, however, used a character-based, or apomorphic, definition of the Class Aves, in which any animal with feathers is considered to be a bird. They argued that the filamentous plumes of Sinosauropteryx represent true feathers with a rachis and barbs, and thus that Sinosauropteryx should be considered a true bird.

Dr. Jäger asked Dr. Ana Lúcia Tourinho, specialist in Opiliones taxonomy, and she concludes that the harvestman is probably a species of the genus Gagrella in the family Sclerosomatidae, with some 1300 other known species. Dr. Jäger stated that his main interest is in huntsman spiders, not harvestmen, but he will be glad if the species had a name. Three more samples were collected in Laos, and now preserved in pure ethanol which allow the specialist to sequence their DNA and plot the species in a tree and he thus place it in a more adequate genus. The species is still undescribed without a scientific name.

Present in a majority of colonies, the tineid moth (belongs to an undescribed genus) is the most common pest of the red paper wasps. The moth lays its eggs and then these eggs hatch into larvae that can burrow from cell to cell and prey on meconia and wasp pupae. While only 0.47% of the brood is lost to predation, the wasps perform many defense mechanisms to protect their nests from these infestations. Adult wasps attempt to remove and kill moth eggs and larvae by chewing down the edges of cells, coating the cells with an oral secretion that gives the nest a dark brownish appearance.

Based on the size of the head capsule, the genus Cyrtopone is not an option, and the petiole structure is different from that seen in Protopone, Cephalopone or Messelepone, leaving the species as part of Pachycondyla or an undescribed genus. Since the condition of the fossil does not show enough other detail, it was placed into Pachycondyla by Dlussky & Wedmann. The species is one of six Pachycondyla species which have been described from Messel Formation fossils. All six of the species were described by Dlussky and Wedmann in the same 2012 paper, the other five being P. eocenica, P. lutzi, P. parvula, P. petiolosa, and P. petrosa.

Other isolated teeth (which Long and Murry (1995) assigned to R. callenderi) were collected two localities in the Blue Hills, east-central Arizona, from the Blue Mesa Member of the Chinle Formation, dating also to the latest Carnian. UCMP locality V92048 have yielded the topotypes UCMPV 173839-41, and the referred teeth UCMPV 139563-75 are from UCMP locality V7307. Parker et al. (2005) confirmed that R. hunti may be assignable to Revueltosaurus, on the basis of undescribed squamosal collected from its referred locality that is nearly identical to that seen in the Petrified Forest material of R. callenderi, thus suggesting that R. hunti is a pseudosuchian.

"Yezosaurus" was the name given to an undescribed genus of prehistoric marine reptile. Originally thought to be a Tyrannosaur dinosaur, it was later identified as a mosasaur or ichthyosaur which lived in what is now Japan.Yezosaurus in the Dinosaur Encyclopaedia at Dino Russ's Lair The "type species", "Yezosaurus mikasaensis", was coined by Obata and Muramoto in 1977, but was not formally described until 2008, when the species T. mikasaensis was described by Caldwell et al (thereby making Y. mikasaensis a nomen nudum). Jimenez-Huidobro & Caldwell (2019) argued that there is not enough sufficient fossil evidence to distinguish between T. mikasaensis and T. oweni and thus reassigned the former to Taniwhasaurus indet.

One is from the Pearl River basin (at least in Guangxi), two from the Yellow River basin, one from the Yangtze River basin (at least in Chongqing and Guizhou) and the final from the Qiantang River (at least in Anhui). Two additional clades are only known from captivity (their wild range is unknown) and no samples are available for the population in the Tibetan Plateau. A 2019 study has identified that the Yangtze River clade comprises the "true" A. davidianus, the Pearl River clade comprises A. sligoi, and the Qiantang clade comprises the undescribed Huangshan Mountains species. Finds in Taiwan may be the result of introduction.

The report notes that they could easily change their identity on a whim or after being persuaded by nationalist organizations, producing sharp changes in ethnic composition of some areas, the most noticeable changes being decrease of number of Belarusians in ten years since 1920 from 75,630 to 36,029 and number of Poles increasing more than could be explained with natural growth and immigration, suggesting that some 5,000 Tutejszy had chosen to identify as Poles. In addition uncertain number of them presumably chose to identify as Russians or Latvians. The group’s speech (język tutejszy) was described in 2003 as “an uncodified and largely undescribed Belarusian vernacular”.

The Dockyard Shale Formation is an undescribed variegated shale of unknown age that lies buried beneath the Gibraltar's dockyard and coastal protection structures. Although these geological formations were deposited during the early part of the Jurassic Period some 175-200million years ago, their current appearance is due to far more recent events of about 5 million years ago. When the African tectonic plate collided tightly with the Eurasian plate, the Mediterranean became a lake that, over the course of time, dried up during the Messinian salinity crisis. The Atlantic Ocean then broke through the Strait of Gibraltar, and the resultant flooding created the Mediterranean Sea.

In 1967, Nabokov commented: "The pleasures and rewards of literary inspiration are nothing beside the rapture of discovering a new organ under the microscope or an undescribed species on a mountainside in Iran or Peru. It is not improbable that had there been no revolution in Russia, I would have devoted myself entirely to lepidopterology and never written any novels at all." The paleontologist and essayist Stephen Jay Gould discussed Nabokov's lepidoptery in his essay, "No Science Without Fancy, No Art Without Facts: The Lepidoptery of Vladimir Nabokov" (reprinted in I Have Landed). Gould notes that Nabokov was occasionally a scientific "stick-in-the-mud".

More recently large-scale mass spectrometry analyses have been used to determine sites of protein phosphorylation. Over the last 4 years, dozens of studies have been published, each identifying thousands of sites, many of which were previously undescribed. Mass spectrometry is ideally suited for such analyses using HCD or ETD fragmentation, as the addition of phosphorylation results in an increase in the mass of the protein and the phosphorylated residue. Advanced, highly accurate mass spectrometers are needed for these studies, limiting the technology to labs with high-end mass spectrometers. However, the analysis of phosphorylated peptides by mass spectrometry is still not as straightforward as for “regular”, unmodified peptides.

Including several diverse aquatic habitats like swamps, lakes, channels and floodplains, the Sudd is rich in fish. Some 70 species have been recorded and this mostly involves fish that are found in much of the Nile system such as marbled lungfish, Senegal bichir, African arowana, Mormyrus caschive, Nile carp, Nile tilapia, mango tilapia, redbelly tilapia, Nile perch, Distichodus rostratus, elongate tigerfish, African tetras, African sharptooth catfish, Synodontis frontosus, S. schall and others. Among the few endemics of the Sudd system are Clarias engelseni, Enteromius yeiensis, Nothobranchius nubaensis, N. virgatus and two apparently undescribed species of Enteromius, and the fish fauna in significant sections still has not been properly studied.

33 At present the Bola Batu babirusa is only known for certain from subfossil remains from the southern arm of Sulawesi. Based on a single skull from central Sulawesi it has been suggested that babirusas from this part of Sulawesi represent an extant population of the Bola Batu babirusa,Groves, 1980, p. 44 and this was followed in the third edition of Mammal Species of the World. However, the most recent major review also found similarities between the central Sulawesi specimen and the Togian babirusa, leading them to conclude that it represents an undescribed taxon and that the taxonomic position of central Sulawesi babirusas only can be determined through additional specimens.

At the request of Joseph Banks, Menzies collected natural history specimens wherever possible during the voyage. During September and October 1791, while the expedition were anchored at King George Sound, he collected numerous plant specimens, including the first specimens of Dryandra (now Banksia) sessilis (Parrotbush) and D. (now Banksia) pellaeifolia. Upon Menzies' return to England, he turned his specimens over to Banks; as with most other specimens in Banks' library, they remained undescribed for many years. Robert Brown gave a lecture, naming the new genus Dryandra in 1809, however Joseph Knight published the name Josephia before Brown published his paper with the description of Dryandra.

From April to May in 1992, in the southern Kattegat there was a large bloom made up of many phytoplankton species, with over 90% biomass being Chrysochromulina species. The most abundant species in the bloom were C. hirta, C. spinifera, C. ericina, C. brevifilum and an undescribed species. C. hirta, C. spinifera, and C. ericina are characterized as relatively small cells with long spines protruding to give the overall organisms a 25-76μm diameter which is too large for the ciliates present to engulf which is likely one reason that the bloom was so successful. Another likely reason for the success of the bloom was the low presence of grazers in the bloom, about 5% of the Chrysochromulina species.

Microlipophrys canevae is a species of combtooth blenny found in the northeast Atlantic Ocean near Portugal and in the Mediterranean Sea. This species grows to a length of TL. A previously undescribed species of combtppth blenny was described from the Adriatic Sea by the French ichthyologist François Charrousset (fr) from two specimens and given the name Lipophrys heuvelmansi. However, in 2015 a comparison of these specimens with specimens of M. canevae showed that L. heuvelsmani was a junior synonym of this species. The specific name honours the friend of Vincuguerra's, Giorgio Caneva, whose work encouraged Vinciguerra to study blennies from the Gulf of Genoa and led to the description of this species.

The German biologist Rainer Willmann described the larvae in a chapter in Martill, Bechly & Loveridge (2007) and erroneously attributed them to the extinct stem group mayfly family Cretereismatidae that he described based on adult specimens from the same locality. During the work for this monograph on the Crato Formation the German palaeoentomologist Günter Bechly and entomologist Arnold H. Staniczek discovered in the fossil collection of the Stuttgart State Museum of Natural History the very adult specimen that later would become the holotype of Mickoleitia longimanus. They figured this fossil in Martill, Bechly & Loveridge 2007 (Fig. 11.90i,j) as undescribed stem group mayfly and indicated in a brief figure legend the possible relationship to the erratic larvae.

The species name derives from Latin denti, teeth, and crena, notch, in reference to the tooth shape which is similar to the crabeater seal. The complete skull was described in 2018 by paleontologists Robert Ewan Fordyce and Felix Marx. It is grouped into the Eocene family Llanocetidae along with Mystacodon and an as yet undescribed specimen OU GS10897 from New Zealand. Though Mitchell, based on the size and density of the bone, thought the specimen was an adult, Fordyce and Marx concluded it was a juvenile due to the loss of both epiphyses–which are the surfaces that the vertebra connects to the other vertebrae to–on the single preserved neck vertebra.

This re- evaluation prompted the inclusion of Yarasuchus within the newly recognised avemetatarsalian clade Aphanosauria. In their examination, Nesbitt and colleagues were able to refer a number of previously undescribed calcanea collected at the site to the hypodigm of Yarasuchus based on their similarity to Teleocrater, and identified ischia that were originally reported as missing. They also removed a number of erroneously referred skull bones and osteoderms from the hypodigm. The relatively complete skeleton of Yarasuchus allowed Nesbitt and colleagues to confidently refer a number of isolated bones as all belonging to specimens of Teleocrater because of their close similarity to those of Yarasuchus, which provided a key reference point for understanding the anatomy of the previously enigmatic taxon.

Several mammals are known from the Mesozoic of Madagascar. The Bathonian (middle Jurassic) Ambondro, known from a piece of jaw with three teeth, is the earliest known mammal with molars showing the modern, tribosphenic pattern that is characteristic of marsupial and placental mammals. Interpretations of its affinities have differed; one proposal places it in a group known as Australosphenida with other Mesozoic tribosphenic mammals from the southern continents (Gondwana) as well as the monotremes, while others favor closer affinities with northern (Laurasian) tribosphenic mammals or specifically with placentals. At least five species are known from the Maastrichtian (late Cretaceous), including a yet undescribed species known from a nearly complete skeleton that may represent a completely new group of mammals.

Composite skeletal diagram, color indicating different specimens Further discoveries of Brachiosaurus material in North America have been uncommon and consist of a few bones. To date, material can only be unambiguously ascribed to the genus when overlapping with the holotype material, and any referrals of elements form the skull, neck, anterior dorsal region, or distal limbs or feet remain tentative. Nevertheless, material has been described from Colorado, Oklahoma, Utah, and Wyoming, and undescribed material has been mentioned from several other sites. In 1883, farmer Marshall Parker Felch, a fossil collector for the American paleontologist Othniel Charles Marsh, reported the discovery of a sauropod skull in Felch Quarry 1, near Garden Park, Colorado.

T. wetmorei was initially placed in the presumed pelecaniform family Cyphornithidae, which had been placed in the "pelecaniform" suborder Cladornithes, together with two other misidentified pseudotooth birds - Palaeochenoides and the family's type genus Cyphornis. The type genus of that supposed suborder, the enigmatic Late Oligocene Cladornis from the Argentinian part of Patagonia, like the present species is only known from a distal right tarsometatarsus end. This was believed to be reminiscent of the (then still undescribed) Tympanonesiotes, and thus it was argued that all four genera were closely related. But Cladornis is more generally held to be a terrestrial bird of unclear affiliations rather than a seabird nowadays, and the Cladornithes are not used anymore by recent authors.

Natio fluviatilis was found in northern Italy, natio tarantium in southern Italy, and nationes thessalonis, kühnelti and laconis were found in parts of Greece. The geographical distribution of natio leucosis was not reported, and it was suggested that a further (undescribed) tribe inhabited the Greek island of Andros. Despite this wealth of infraspecific taxa, they are rarely used by scientists, and some have questioned directly the value of defining infraspecific taxa within P. fluviatile. In 1990, the population on Malta was described as a separate subspecies, Potamon fluviatile lanfrancoi, and that taxon has become a conservation icon in Malta following its legal protection in 1993, although not all scientists recognise the taxon.

During the Middle Triassic, the Chaohu strata were deposited in an oceanic basin relatively far from the coast, which was bordered on the south by shallower waters and carbonate platforms, and on the north by a continental slope and deeper basins. The ichthyosauriforms Sclerocormus and Chaohusaurus are both found in Majiashan Quarry along with Cartorhynchus; Sclerocormus is known from the younger Bed 719 (248.16 Ma), while Chaohusaurus is found in both beds. The sauropterygian Majiashanosaurus is known from Bed 643. Fish diversity in the Majiashan Quarry is poorer than other localities; the most common fish is Chaohuperleidus, the oldest known member of the Perleidiformes, but a species of the wide-ranging Saurichthys and several undescribed fish are also unknown.

A. palatasi was initially thought to be a morphotype of the giant thresher A. grandis (above). In 2002, rumors began about discoveries of a new type of large serrated shark teeth pertaining to an undescribed species of mackerel shark from Miocene deposits in South Carolina by amateur collectors and fossil dealers. While these fossils were often dismissed as teeth from other sharks such as the megalodon and the false-toothed mako (Parotodus benedenii), a consensus was reached that they were likely from a morphotype of the giant thresher Alopias grandis. Despite the large attention given by amateur collectors and fossil dealers, such fossils remained unmentioned in the scientific literature for many years.

Some elements in the collection belonged to an infant specimen (MNA P1.3181), the youngest known example of this genus, and one of the earliest known infant theropods from North America, only preceded by some Coelophysis specimens. The juvenile specimen includes a partial humerus, a partial fibula, and a tooth fragment. In 2005, paleontologist Ronald S. Tykoski assigned a specimen (TMM 43646-140) from Gold Spring, Arizona, to Dilophosaurus, but in 2012, American paleontologist Matthew T. Carrano and colleagues found it to differ in some details. In 2020, the paleontologists Adam D. Marsh and Timothy B. Rowe comprehensively redescribed Dilophosaurus based on the by then known specimens, including specimen UCMP 77270 which had remained undescribed since 1964.

In their 1997 monograph, "A skeletal revision of Nepenthes (Nepenthaceae)", Matthew Jebb and Martin Cheek tentatively referred specimens collected from Bukit Bakar, near Macang, Kelantan, to N. sanguinea. These were Stone & Chin 15238, deposited at Universiti Kebangsaan Malaysia near Kuala Lumpur (KLU), and Shah & Shukor 3168, also held at KLU as well as the Forest Research Institute of Malaysia in Kepong (KEP). They noted that the plants exhibited some unusual morphological features, such as larger leaves and decurrent, almost petiolate leaf bases, suggesting that they might represent an as-yet undescribed taxon. Bukit Bakar in 2007 Field studies confirmed that the taxon represented a separate species, and it was formally described as N. benstonei in 1999 by Charles Clarke.

The Victoria haplochromines are distinctly sexually dimorphic (males relatively brightly colored; females dull), and their ecology is extremely diverse, falling into at least 16 groups, including detritivores, zooplanktivores, insectivores, prawn-eaters, molluscivores and piscivores. As a result of predation by the introduced Nile perch, eutrophication and other changes to the ecosystem, it is estimated that at least 200 species (about 40 percent) of Lake Victoria haplochromines have become extinct, including more than 100 undescribed species. Initially it was feared that this number was even higher, by some estimates 65 percent of the total species, but several species that were feared extinct have been rediscovered after the Nile perch started to decline in the 1990s.IUCN Red Lists: Geographic Patterns.

But he was not always in India; he maintained a connection with scientific societies, being elected to the Linnean Society in 1842. On a return voyage to India in 1846 he took advantage of a short stop at Aden to collect plants. Of the 40 specimens, eleven turned out to be previously undescribed species that he reported in a scientific journal. In correspondence from Charles Darwin to J.D. Hooker mentions a conversation held between himself, Edgeworth and biologists John Lubbock and George Charles Wallich, at a meeting of the Linnean Society of London (18 April 1861) less than two years after the publication of Darwin's On the Origin of Species (22 November 1859).

Seed yellowish white to brownish, suborbicular or flattened. Most of the species belonging to Corynopuntia show a very similar morphology, apparently with few differences, so this genus was little studied. Recent in-depth field and lab researches are improving the knowledge about these plants, showing the existence of many undescribed species.Rebman, J.

In 1934 Armstrong isolated a previously undescribed neurotropic virus found during the experimental transmission of encephalitis virus from the 1933 St. Louis epidemic from which it was differentiated and he demonstrated the virus in the central nervous system, spinal fluid, blood and urine of monkeys and in the brain and blood of mice during the experimental disease. In the majority of the monkeys there was more or less diffuse and irregular cellular infiltration of the meninges. In most animals there was a more or less pronounced swelling, edema and lymphocytic infiltration of the choroid plexus, i.e. the cellular membrane lining the intracerebral ventricles, which led him to name the disease lymphocytic choriomeningitis.

Worcester's progress report included a description of the specimen and an explanation on how they had obtained it: Nachtrieb did not assign the name to a specific genus, noting that it was "an undescribed member of the Lemuridae". The following year, the English naturalist Richard Lydekker published the combination Lemur menagensis in The Zoological Record. This makes Lydekker the authority of the species name menagensis, because he was the first to use the specific name in combination with the name of a genus, although some subsequent authors credited other workers. In his influential 1953 book Primates: Comparative Anatomy and Taxonomy, the primatologist William Charles Osman Hill placed all the slow lorises in one species, N. coucang.

The invertebrates within F. citrifolia syconia in southern Florida include a pollinating wasp, P. assuetus, up to eight or more species of non-pollinating wasps, a plant- parasitic nematode transported by the pollinator, a parasitic nematode attacking the pollinating wasp, mites, a midge, and a predatory rove beetle whose adults and larvae eat fig wasps. Nematodes: Schistonchus laevigatus (Aphelenchoididae) is a plant-parasitic nematode associated with the pollinator Pegoscapus assuetus and syconia of F. citrifolia. Parasitodiplogaster laevigata is a parasite of the pollinator Pegoscapus assuetus. Mites: belonging to the family Tarsonemidae (Acarina) have been recognized in the syconia of F. aurea and F. citrifolia, but they have not been identified even to genus, and their behavior is undescribed.

She also included GPS coordinates from Vimy, Alberta, that helped Donovan link the data to identify the phenomenon. One of the aurora watchers, photographer Chris Ratzlaff, suggested the name "STEVE" from Over the Hedge, an animated comedy movie from 2006, in which its characters chose that as a benign name for something unknown. Reportage of the heretofore undescribed unusual "aurora" went viral as an example of citizen science on Aurorasaurus. Robert Lysak, during the fall meeting of the American Geophysical Union in December 2016, suggested "Strong Thermal Emission Velocity Enhancement" as a backronym of STEVE, one that has since been adopted by the team at NASA Goddard Space Flight Center studying the phenomenon.

The spade-toothed whale (Mesoplodon traversii) is a very little-known and the rarest species of beaked whale. It was first named from a partial jaw found on Pitt Island, New Zealand, in 1872; reported and illustrated in 1873 by James Hector, and described the next year by John Edward Gray, who named it in honor of Henry Hammersley Travers, the collector. This was eventually lumped with the strap-toothed whale, starting as early as an 1878 article by Hector, who never considered the specimen to be specifically distinct. A calvaria found in the 1950s at White Island, also New Zealand, initially remained undescribed, but was later believed to be from a ginkgo-toothed beaked whale.

A study published in the year 2000 found O-M117 in 4.3% (1/23) of a sample representing Japan.Peter A. Underhill, Peidong Shen, Alice A. Lin et al., "Y chromosome sequence variation and the history of human populations," Nature Genetics • Volume 26 • November 2000 In a study published by Chinese researchers in the year 2006, O-M117 was found with high frequency (8/47 = 17.0%) in a sample of Japanese of undescribed geographical origin (Xue et al. 2006). However, in a study published by Japanese researchers in the year 2007, the same haplogroup was found with much lower frequency (11/263 = 4.2%) in a larger sample of Japanese from various regions of Japan (Nonaka et al. 2007).

Beehler and colleagues, however, returned with the first ever photographs of two species of birds, the bronze parotia (Parotia berlepschi) and the golden-fronted bowerbird (Amblyornis flavifrons), that previously were known only from a few specimens. Additionally, a previously unknown species of honeyeater was discovered, it being scientifically described in 2007 as the wattled smoky honeyeater (Melipotes carolae). The specific epithet, carolae, commemorates Carol Beehler, the wife of Bruce Beehler. Together with a team from 60 Minutes, Beehler returned to the Foja Mountains in 2007, resulting in the first ever filming of several of the species discovered in 2005, as well as encounters with an undescribed giant rat (Mallomys sp.) and a tiny pygmy possum (Cercartetus sp.).

The first undisputed auk fossils are from the middle Miocene (15 million years ago). The first Aethia fossils date from the late Miocene (8–13 million years ago) and the four extant species likely diverged rapidly about 5 million years ago. There are one or two fossil species which lived in the area of today's California during the Late Miocene, some 5 million years ago: Aethia rossmoori Howard, 1968 (Monterrey Formation of Orange County),and an undescribed taxon tentatively placed in this genus. From the Pliocene there are Aethia barnesi N. A. Smith, 2013 (San Mateo Formation of San Diego County, California, and Aethia storeri N. A. Smith, 2013 (San Mateo Formation of San Diego County, California.

A partial adult skull from the Bayan Mandahu Formation has been assigned to a distinct species, Velociraptor osmolskae. Undescribed V. mongoliensis skull All of the fossil sites that have yielded Velociraptor remains preserve an arid environment with fields of sand dunes and only intermittent streams, although the younger Barun Goyot environment seems to have been slightly wetter than the older Djadochta. The posture of some complete fossils, as well as the mode of preservation most show within structureless sandstone deposits, may show that a number of specimens were buried alive during sandstorm events common to the three environments. Many of the same genera were present across these formations, though they varied at the species level.
