Fossil evidence thus supports the former existence of a distinct species of spruce: Picea critchfieldii. Plant macrofossils are fossilized deposits that represent the multicellular sporophyte stage in the plant life cycle.

The marsh is believed to have originated about 7,000 years ago. In 1996 of the northern part of the Muthurajawela marsh was declared a wetland sanctuary by the government, under the Flora and Fauna Protection Act, in recognition of its vast bio-diversity. The region supports 192 distinct species of flora and 209 distinct species of fauna, including Slender Loris, as well as another 102 species of birds. Some of the identified species have been shown to be indigenous to the marsh.

A species complex is typically considered as a group of close, but distinct species. Obviously, the concept is closely tied to the definition of a species. Modern biology understands a species as "separately evolving metapopulation lineage" but acknowledges that the criteria to delimit species may depend on the group studied. Thus, many traditionally defined species defined, based only on morphological similarity, have been found to be several distinct species when other criteria, such as genetic differentiation or reproductive isolation, are applied.

This was previously considered to be a distinct species, Coryphella stimpsoni.Shepard, A., 2006 (Mar 31) Sea Slug Forum : Color variation in Flabellina salmonacea; accessed : 17 January 2011 The maximum recorded length is 50 mm.

Although Zeuner suggested that O. richmondia may represent a distinct species from examination of the male genitalia, he continued to regard it as a subspecies of O. priamus. Based on Zeuner's argument, D'Abrera (1975) treated O. richmondia as a full species, although this arrangement was not accepted by Haugum & Low (1971). Nonetheless, D'Abrera's treatment of O. richmondia as a distinct species has been followed by most Australian authors since (e.g. Common & Waterhouse 1981, Hancock 1983, 1991; Parsons 1996a, 1996b and Hancock & Orr 1997, Braby 2000).

In a 2012 publication, mycologist Mike Davis and colleagues suggest that western North American Russula brevipes comprise a complex of at least four distinct species. According to MycoBank, the European species Russula chloroides is synonymous with R. brevipes, although Index Fungorum and other sources consider them distinct species. The specific epithet brevipes is derived from the Latin words brevis "short" and pes "foot", hence "short-footed". Common names used to refer to the mushroom include short-stemmed russula, short-stalked white russula, and stubby brittlegill.

Species within the genus Chaetomium are generally classified based on morphology of asci, ascospores, and terminal hairs. This however, leads to discrepancies in classification and determination of synonymous versus distinct species. For example, Dreyfuss (1976) considered Ch. aureum, Ch. trilaterale, Ch. fusiforme, Ch. cupreum, Ch. confusum, Ch. humicola, and Ch. rubrogenum to be a single species, whereas Ch. trilaterale was considered to be a distinct species by Millner et al. 1977. Molecular phylogenetic determination of fungi by means of protein electrophoresis has been reported, but with varying success.

Some have classified it as a subspecies of house sparrow, a subspecies of the Spanish sparrow, or as a distinct species, a treatment followed if only for convenience by authorities such as the Handbook of the Birds of the World. A DNA analysis by Glenn-Peter Sætre and colleagues published in 2011 indicated an origin of the Italian sparrow through hybridisation between the Spanish and house sparrows, and Sætre and colleagues argued that given its origins and the limited extent of hybridisation, the treatment as a distinct species was supported.

Despite Boulenger's classification, the species was later synonymized with the Chinese giant salamander (A. davidianus), and eventually forgotten. However, a study published in 2018 found that the Chinese giant salamander actually consisted of numerous clades restricted to different river basins, with many of them being distinct enough to be considered separate species. A further study of museum specimens found that the South Chinese population likely represented a distinct species and was also the subject of Boulenger's initial study, and thus supported the revival of A. sligoi as a distinct species.

Publication R10-RG-209. PAGES 30 & 31. This mushroom is inedible due to its woody texture, but it is useful as tinder. There is currently a splitting of F. pinicola occurring to isolate distinct species that have all previously been classified as F. pinicola.

In the last three decades of the 20th century, Canna species have been categorised by two different taxonomists, Paulus Johannes Maria Maas from the Netherlands and Nobuyuki Tanaka from Japan. The two taxonomists are in agreement that this is a separate and distinct species.

Although the Maastrichtian Palaeosaniwa has traditionally been referred to this species, it succeeds it by roughly ten million years. Given the distance in time between these animals, they are likely to represent distinct species, but the available fossils are too incomplete to be certain.

Colias caucasica balcanica is a butterfly in the family Pieridae. It is the European subspecies of Colias caucasica. It is found in Bosnia and Herzegovina, Bulgaria, Serbia, Montenegro, North Macedonia and Greece.Fauna Europaea It used to be considered a distinct species (Colias balcanica).lepiforum.

Munz, Philip Alexander 1935. Manual of Southern California Botany 601 Peter Raven later wanted to recognize the Channel Island plants as a distinct species within Artemisia, but the name Artemisia insularis had already been used for a Kuril Islands plant in 1936.Kitamura, Siro 1936.

Mycterosuchus nasutus was synonymized with Steneosaurus leedsi by Adams-Tresmand in 1987, but is recovered as a distinct species in the cladistic analysis of Osi et al. of 2018.S. M. Adams-Tresman. 1987. The Callovian (Midde Jurassic) teleosaurid marine crocodiles from central England.

Based on studies of DNA, M. tomentosa is clearly a distinct species apart from the yellow morels (M. esculenta & ssp.) and black morels (M. elata & ssp.). Mushroom collectors also use the common name "gray morel" for M. esculenta-type morels in eastern North America.

Such a reassignment would have implications for other species of Pterygotus as well, with P. impacatus potentially also representing a synonym of E. osiliensis. Subsequent studies and lists of eurypterid species have continued to treat P. monroensis and P. impacatus as distinct species of Pterygotus.

The agile antechinus was long considered to be a form of the brown antechinus (Antechinus stuartii), and was only recognised as a distinct species after a study of genetic variation within the brown antechinus in 1980. However, it was not formally described until 1998.

Leptofauchea coralligena is a species of red algae that was first discovered in the Mediterranean Sea in 2007. Molecular analysis determined that Rhodymenia ardissonei was in fact two distinct species. Rhodymenia ardissonei lives in relatively shallow water whereas Leptofauchea coralligena lives in deeper waters.

Omphalotus illudens is sometimes confused with edible chanterelles, but is poisonous to humans when eaten, whether raw or cooked, and typically causes vomiting, cramps, and diarrhea. Although some older literature claims the name is synonymous with Omphalotus olearius, phylogenetic analysis confirms they are distinct species.

Accordingly, there is confusion in older literature reports on the physiological and habitat regularities of C. sphaerospermum in the strict sense. This fungus is most phylogenetically similar to C. fusiforme. According to modern phylogenetic analyses, the previously synonymized species, Cladosporium langeroni, is a distinct species.

Tetrapod Zoology. 18 January 2008. Accessed 31 January 2008 (). The scientists who described Tupandactylus did not name a Tupandactylus navigans (but instead suggested it was synonymous to Tupandactylus imperator), and Tapejara navigans was not formally reclassified as a distinct species of Tupandactylus until 2011.

Recognised as a distinct species in 2001 the Ugandan red colobus had previously been considered a subspecies of P. badius, and later a subspecies of P. foai. There is currently a debate as to whether it should be considered a subspecies of P. rufomitratus.

Tarucus balcanicus nigra, the black-spotted Pierrot, is a small butterfly found in India that belongs to the lycaenids or blues family. Formerly regarded as a distinct species, it is nowadays considered to be a well-marked eastern subspecies of the Balkan Pierrot (T. balkanicus).

However, recent chromosome analysis of Salvia species shows that S. tingitana is a distinct species. S. tingitana shows a chromosome count of 2n=42, which is unusual (though not unique) for the genus Salvia. Far more common are 2n=14, 16, 20, and 22.

In 1994, it was suggested that its distinct pelage colour, pattern and cranial measurements warrant a specific status. But results of phylogeographic analysis did not support this. The validity of the genetic work has been questioned. Others regarded it as "likely [a] distinct species".

The type species, G. eggenburgensis, is known from the early Miocene of Austria. Myrick Jr. (2001) proposed synonymizing Gavialosuchus americanus with Thecachampsa antiqua. Piras et al. (2007) advocated transferring both G. americanus and G. carolinensis to Thecachampsa as distinct species of the latter genus, however.

Individuals without the lines on the body occur in some populations. Although currently considered to be a synonym of the European species Ancula gibbosa there are significant differences in color and shape of the extra-branchial papillae and this is probably a distinct species.

S. coccinea var. jurana was described by Jean Boudier (1903) as a variety of the species having a brighter and more orange-colored fruit body, and with flattened or blunt-ended ascospores. Today it is known as the distinct species S. jurana. S. coccinea var.

Cunninghamia lanceolata is a species of tree in the cypress family, Cupressaceae. It is native to south-central and southeast China. Cunninghamia konishii is treated as a distinct species by some sources, although it has also been suggested that it is conspecific with C. lanceolata.

Titanium(III) chloride is the inorganic compound with the formula TiCl3. At least four distinct species have this formula; additionally hydrated derivatives are known. TiCl3 is one of the most common halides of titanium and is an important catalyst for the manufacture of polyolefins.

Allomyces macrogynus is a species of fungus in the family Blastocladiaceae. It was first described by mycologist Ralph Emerson in 1941 as a variety of Allomyces javanicus, and later given distinct species status in 1954. Its genome has been sequenced by the Broad Institute.

They were once described as a distinct species, the "black barbthroat" ("T. grzimeki"). Similarly, the proposed subspecies abrawayae is apparently based on individual variation occurring in adults and not taxonomically distinct either.Mallet-Rodrigues (2006) The call of this species is a high-pitched sweet.

Analysis of mitochondrial DNA showed that the western cicada killer contains two divergent clades, which may represent distinct species. The two clades appeared to be split by the Rocky Mountains, with one occurring mainly to the south and east, the other to the west.

In Europe, several orange-red capped species exist, which differ mainly in habitat. L. albostipitatum grows with aspen and has white scales on the stipe. In coniferous forests, L. vulpinum occurs around pine and spruce trees. Not all authors recognise these as distinct species.

The taxonomy of this species is complicated, and genetic data indicate that it comprises at least three mitochondrial DNA lineages, each of which may represent a distinct species: a temperate southern African form, a subtropical/tropical southern African form, and a north-western African form.

Numerous other species of Tympanocryptis across Australia were formerly classified under T. pinguicolla, but all of these have ultimately been split due to scientific studies finding them to be distinct species. Two populations from the Darling Downs were found in a 2014 study to actually be two new, distinct species, T. condaminensis and T. wilsoni. A 2019 study found a population near Canberra to actually represent an isolated eastern population of T. lineata, while two populations near Cooma and Bathurst respectively represented two new species, T. osbornei and T. mccartneyi. This has left the Victorian population to be the only representative member of the species.

However, after the finding that Lactarius actually represented more than one genus, the species Lactarius torminosus was conserved as type for that genus. Thus, L. piperatus is now the type species of Lactifluus, which was split from Lactarius and contains mainly tropical milk-caps, but also some species of the north temperate zone. Phylogenetic research showed that L. glaucescens, sometimes considered only a variety of L. piperatus, is a distinct species in Europe. Furthermore, the existence of at least ten lineages worldwide, with no overlap among continents, was shown for the group around L. piperatus, suggesting that populations in North America might actually be distinct species.

He considered it a distinct species as this type specimen differed from the common treeshrew by larger teeth and skull, darker coloured fur on the back and a more coarsely grizzled tail.Miller, G. S. Jr. (1903). Seventy New Malayan Mammals. Smithsonian Miscellaneous Collections 45: 1–73.

Graphium stresemanni is a vulnerable species of butterfly in the family Papilionidae. It is endemic to the Indonesian island of Seram. It closely resembles the related Graphium weiskei, a more common species from New Guinea but has been treated as a distinct species. It is rare.

The two populations are quite isolated from each other, and molecular genetics seems to have settled the matter in favour of two distinct species for the present. On the other hand, there seems to be little distinction between the northern and Baja Californian populations within M. crissalis.

Which is still considered a variant by the American Iris Society. In 1981, Brian Mathew notes in his book 'The Iris' that "The Flora of the USSR separates this as a distinct species, distinguished from Iris ruthenica ". Iris uniflora is a tentatively accepted name by the RHS.

P. Domning. 1996. Bibliography and Index of the Sirenia and Desmostylia. Smithsonian Contributions to Paleobiology 80:1-611 However, recent cladistic studies find the taxon distantly related to the Dioplotherium type species, and specimens from Brazil attributed to allisoni appear to be a distinct species instead.

Grindelia hirsutula is native to North America, widespread across Canada and in California and Oregon.USDA: Grindelia hirsutula distribution map The species is highly variable, and many local populations have been named as varieties or as distinct species. All these taxa do, however, intergrade with one another.

In 1914, Friedrich Dahl synonymized G. gambeyi with Gasteracantha rubrospinis, musing, however, that G. gambeyi might be a species between G. rubrospinis and Gasteracantha fasciata. The World Spider Catalog does not follow Dahl in this case and retains G. gambeyi as a distinct species in the catalog.

Arctic cisco (Coregonus autumnalis) is an anadromous species of freshwater whitefish that inhabits the Arctic parts of Siberia, Alaska and Canada. It has a close freshwater relative in several lakes of Ireland, known as the pollan, alternatively regarded as conspecific with it, or as a distinct species.

A draft genome sequence of M. abscessus subsp. bolletii BDT was completed in 2012. Since then, a large number of strains from this subspecies have had their genomes sequenced, leading to a clarification of subspecies boundaries. In 1992, M. abscessus was first recognised as a distinct species.

P. glutinosus is one of 57 species in the genus Plethodon and was one of the first of its cogeners to be described. Due to its large geographic range, some taxonomic researchers have suggested splitting P. glutinosus into several distinct species, but this is not widely accepted.

The current classification of the plant is as a distinct species. Some botanists and the 1993 edition of "The Jepson Manual" had classified it as Juglans californica subsp. hindsii, a subspecies of Juglans californica (Southern California black walnut).Jepson Manual (1993) Treatment for Juglans californica subsp.

It may be threatened by the invasive lionfish. Adult and young adult damselfish differ significantly in terms of body color. The difference was so stark that researchers believed the adult and young adult forms were two distinct species. Adults are brown with a yellow caudal fin.

Physically, the species resembles the bottlenose dolphins, but differs sufficiently to be placed in a separate genus, Sotalia. The Guiana dolphin (Sotalia guianensis), a related dolphin present in coastal and estuarine environments and formerly grouped together with the tucuxi, have recently been recognized as a distinct species.

Schistometopum gregorii is endemic to the coastal East Africa in Kenya and Tanzania; it is known from the Tana River Delta area in Kenya (its type locality) and between Bagamoyo and Rufiji River in Tanzania. It is possible that the Kenyan and Tanzanian populations are distinct species.

The Papuan pygmy mulga snake (Pseudechis rossignolii) is a venomous snake of the family Elapidae native to Australia, genetically confirmed as a distinct species in 2017. It was originally described by Raymond Hoser in 2000 as Pailsus rossignolii, naming it for Victorian snake handler Fred Rossignoli.

Illicium guajaibonense is a shrub endemic to Pinar del Rio located in western Cuba. It has only recently been recognized as a distinct species; previously it was considered to be subspecies of I. cubense. I. guajaibonense differs from I. cubense in flower color and other characters.

How many distinct species exist or how they might be organized within the genus is not clear. The plants are variable and the taxa are not always distinct from one another. Some American taxa have been described as complexes rather than separate species.Naganowska, B., et al. (2005).

A similar, but phylogenetically distinct species found in eastern North America is Omphalotus illudens. Unlike chanterelles, Omphalotus olearius and other Omphalotus species contain the toxin illudin S, and are poisonous to humans. While not lethal, consuming this mushroom leads to very severe cramps, vomiting, and diarrhea.

It was then recombined as a distinct species in 1985 by Emile Jacquetant, and validated the following year by Jacquetant and Bon.Jacquetant E, Bon M. (1985). Typifications et mises au point nomenclaturales dans l’ouvrage ‘‘Les morilles’’ (de E. Jacquetant), Nature-Piantanida 1984. Documents Mycologiques 14:1.

The Flora of China unites all kumquats as the single species, Citrus japonica. Based on chromosomal analysis, Yasuda, et al., identified Jiangsu and Malayan kumquats as hybrids and see the remainder of Eufortunella as a single species, while retaining the Hong Kong kumquat as a distinct species.

Cunninghamia konishii is a species of tree in the cypress family, Cupressaceae. It is native to southeast China, Taiwan, Laos and Vietnam. Although C. konishii is treated as a distinct species by many sources, it has also been suggested that it is conspecific with C. lanceolata.

In Weishampel, Dodson and Osmolska (eds). The Dinosauria Second Edition. University of California Press. 137-150. However, a few authors continued to treat Dromiceiomimus as valid, and Longrich (2008, 2014) treated ROM 840 (holotype of Struthiomimus samueli) as a distinct species of ornithomimid related to Ornithomimus.

Light spots are on the sides. Some individuals and even populations are black (melanistic) and have been described as a separate species, Plethodon gordoni. However, these are not genetically distinct from ordinary P. dunni and are presently not considered a distinct species. It has no larval stage.

T. navonae has a long and narrow whip-like anterior body. Its posterior body is broad and hand- like. Males and females exhibit 1:1.2-1:1.4 ratio between anterior and posterior body length. T. navonae have several features that distinguish them as a distinct species.

Mastrus ridens is a species of ichneumon wasp. It was discovered in Kazakhstan in the 1990s, but it was not described as a distinct species from the similar M. ridibundus until 2010. This species is of interest as a potential biological control agent of the codling moth.

The Taiwan bush warbler (Locustella alishanensis) is a species of Old World warbler in the family Locustellidae. It is found only in Taiwan. Its natural habitat is undergrowth and grassland in elevation. It was first recorded in 1917 and named as a distinct species in 2000.

Catopsilia pomona, the common emigrant or lemon emigrant, is a medium-sized pierid butterfly found in Asia, Cambodia and parts of Australia. The species gets its name from its habit of migration. Some early authors considered them as two distinct species Catopsilia crocale and Catopsilia pomona.

As noted by Westaway et al. (MC Westaway et al. [2015]. Mandibular evidence supports Homo floresiensis as a distinct species. PNAS 112[7], E604-E605), "Many interesting questions about the Liang Bua fossils remain unanswered, but whether LB1 is a pathological H. sapiens is not one of them".

It is known only from Mount Talang in Sumatra, to which N. talangensis is endemic. Nepenthes talangensis was only described as a distinct species in 1994.Nerz, J. & A. Wistuba 1994. Five new taxa of Nepenthes (Nepenthaceae) from North and West Sumatra . Carnivorous Plant Newsletter 23(4): 101–114.

It was reportedly first discovered on leaf mulch in Highgate Woods, north London. The edibility of the mushroom is not known with certainty.

Given its abundance and the fact that it is relatively easy to keep in aquaria, Glyptonotus antarcticus has become an important model organism used as a research object in ecological, biochemical and physiological studies. A 2005 genetic study suggested that Glyptonotus antarcticus may in fact represent several distinct species.

Originally given subspecific status to the bharal (Pseudois nauyar), morphological research conducted in the 1970s led it to be considered a distinct species. However, recent molecular analysis has shown the difference between the two species is slight, and suggests it should be treated as a subspecies of the bharal.

A distinct species related to Disocactus ackermannii, D. phyllanthoides has previously been placed in Nopalxochia, but the generic status for that taxon does not have much support. This species, like others of the former Nopalxochia, shows affinity to Weberocereus making the systematics of this group even more complex.

S. hamatus is a distinct species, distantly related to the grandiflorus-complex. Selenicereus radicans (DC.) A. Berger seems to belong here, but it is impossible to know for sure as the original description is brief and no type seems to exist. The publication of Cereus radicans predates C. hamatus.

Labeo dussumieri (Malabar Labeo) is fish in genus Labeo known to occur in west-flowing rivers of the Western Ghats. Earlier Sri Lankan population was considered as the same species as L. dussumieri, recent phylogenetic and physiological differences suggest that Sri Lankan population is a distinct species, Labeo heladiva..

It is deposited at the herbarium of the Bogor Botanical Gardens along with two isotypes. Nepenthes eustachya was described in 1858 by Friedrich Miquel. In 1908, John Muirhead Macfarlane retained N. eustachya as a distinct species in his revision of the genus, titled "Nepenthaceae".Macfarlane, J.M. 1908. Nepenthaceae.

It was initially assigned to Balaenoptera cf. acutorostrata by Shinohara (2012) and thought to be Pliocene in age, but analysis of diatoms in the matrix and preparation showed it to not only late Miocene but also a distinct species of extinct rorqual.Yamashita, S. 1989. Fossils from Numata Town.

Although it was first discovered by Europeans in 1597, and was the subject of a botanical illustration in 1605, the plant was first described as a distinct species according to the modern Linnaean system by the naturalist Robert Brown in his 1810 treatise On the Proteaceae of Jussieu.

Natural History Publications (Borneo), Kota Kinabalu. However, Charles Clarke retained N. faizaliana as a distinct species in his monograph Nepenthes of Borneo, which was published a few months after the work of Jebb and Cheek. This interpretation has been supported by subsequent authors.Phillipps, A., A. Lamb & C.C. Lee 2008.

Later authors considered it the same species as Cyprinodon macularius. In the 1940s, Robert Rush Miller again described C. nevadensis as a distinct species, and identified six subspecies, including C. n. nevadensis. Other subspecies include the Amargosa River pupfish (C. n. amargosae), the Ash Meadows pupfish (C. n.

Awaous stamineus is a species of goby native to the Hawaiian Islands. It has been considered a synonym of Awaous guamensis but recent work based upon morphological and genetic differences has recognized Hawaiian populations as being distinct. Consequently, Hawaiian Awaous are now recognized as a valid, distinct species.

Amanita augusta is a species of agaric fungus in the family Amanitaceae. Found in the Pacific Northwest region of North America, it was formerly referred to as Amanita franchetti sensu Thiers, but suspected of being a distinct species. It was formally described as a new species in 2013.

The grey trembler (Cinclocerthia gutturalis) is a songbird species in the family Mimidae. It is found only in Martinique and Saint Lucia, the Martinique trembler (C. g. gutturalis) on the former island, the Saint Lucia trembler (C. g. macrorhyncha) - which might be a distinct species - on the latter.

Many early depictions of Geosaurus were based on a nearly complete specimen described by Eberhard Fraas, which Fraas classified as a distinct species of Geosaurus, G. suevicus. This specimen was found in Germany and dated to the late Jurassic (Late Kimmeridgian) period.Fraas E. 1901. Die Meerkrokodile (Thalattosuchia n.

Scientist thought at first that there are 2 varieties of Phytophthora fragariae: P. fragariae var. fragariae, which refers to the pathogen that attacks strawberries, and P. fragariae var. rubi, which refers to the variety that is the raspberry pathogen. Recently, the latter is considered a distinct species, Phytophthora rubi.

The Rio Grande leopard frog was once considered a subspecies of the northern leopard frog, but was later recognized as a distinct species due to distinct mating call and morphological differences. Recent research has placed Rio Grande leopard frogs in the Scurrilirana species group of the subgenus Pantherana.

Genetic analysis suggests P. biaculeatus is monophyletic with Amphiprion, closely related to A. ocellaris and A. percula. This would make Premnas a synonym of Amphiprion. The taxon epigrammata from Sumatra probably should be recognized as a distinct species, Premnas epigrammata (Fowler, 1904).Kuiter, R. H., and H. Debelius.

Audubon's shearwater itself has around 10 subspecies. Several have at one time or another been suggested to constitute separate species. For example, the Galápagos Islands population has turned out to be a very distinct species, the Galápagos shearwater (P. subalaris); it is apparently related to the Christmas shearwater (P.

Furcifer monoceras is a species of chameleon endemic to Madagascar. It is only known from one holotype specimen from Betsako, east of Mahajanga. Long considered conspecific with the rhinoceros chameleon (F. rhinoceratus), a 2018 study of minor details of its morphology indicated that it was a distinct species.

The green neon tetra (P. simulans) and black neon tetra (Hyphessobrycon herbertaxelrodi) are distinct species—the latter belongs to a different genus—and not color varieties. The cardinal tetra (P. axelrodi) is also a similar species, but its greater extent of red coloring distinguishes it from the neon tetra.

The species was originally named Agaricus traganus by Elias Magnus Fries. It is commonly known as the "gassy webcap" the "lilac conifer Cortinarius", or the "pungent Cort". Some authorities consider the American variant to be a distinct species, Cortinarius pyriodorus, reserving the name C. traganus for the European version.

Some authors and herbaria accept C. opaca as a distinct species and others consider it to be inseparable from C. terminalis and C. tumescens. To the extent that the species can be reliably differentiated, C. terminalis has thinner leaves, larger buds and fruit and thicker pedicels than C. opaca.

The Citico darter (Etheostoma sitikuense) is a threatened species of darter native to Tennessee. This species was formerly subsumed within Etheostoma percnurum (duskytail darter). The E. percnurum group now consists of four distinct species: E. percnurum, E. marmorpinnum (marbled darter), E. lemniscatum (tuxedo darter), and E. sitikuense.Blanton, Jenkins 2008.

Scadoxus longifolius is a herbaceous plant from Zaire. It is only known from a single collection, and little information is available about it. It appears to be closely related to Scadoxus cinnabarinus, and Inger Nordal and Thomas Duncan suggested in 1984 that it may not be a distinct species.

Subsequent DNA analysis by Randall and DiBattista (2012) showed that the Hawaiian population of Etrumeus micropus is distinct species, which the authors named Etrumeus makiawa.Randall, J.E. & DiBattista, J.D. (2012). Etrumeus makiawa, a new Species of Round Herring (Clupeidae: Dussumierinae) from the Hawaiian Islands. Pacific Science 66 (1): 97-110.

The Chihuahuan pocket mouse (Chaetodipus eremicus) is a species of heteromyid rodent found in the southwestern United States and Mexico. It was formerly considered a subspecies of the desert pocket mouse (C. pencillatus), but was determined to be a distinct species in 1996, following analysis of its mitochondrial DNA.

It hybridizes extensively with the golden-collared manakin in a limited area in Bocas del Toro Province, Panama. The hybrids, which show a lemon yellow collar in males, were at one time considered a distinct species, the almirante manakin (Manacus×cerritus) (Brumfield et al., 2001; McDonald et al., 2001).

Rheum rhabarbarum (syn. R. undulatum) was one of a number of distinct species grown in Europe before the beginning of the 18th century. Initially the roots of a related species, possibly R. rhaponticum, were used for medicinal purposes. A putative hybrid of unknown origin, Rheum × hybridum, was also grown.

Its fruit is edible but rarely eaten except as an emergency food. The young leaves are pickled or cooked and eaten as a vegetable with pig meat by highlanders. The lowland form of this species found commonly below 900 meters is recognized as a distinct species, Ficus brusii.

In his original (1949) version of Agaricales in Modern Taxonomy, Rolf Singer considered it a subspecies of A. muscaria, but noted that it may be regarded as a separate species; in the fourth edition (1986), he listed it as a distinct species. A. regalis is classified in a section of Amanita within the genus, a grouping of related Amanitas that have a ring on the stem (or remnants thereof), and a bulb at the base of it.Jenkins (1986), p. 16. More recently, a Japanese group studied the biogeography of A. muscaria and related species, and, using molecular phylogenetic analysis, concluded that the taxon should be considered a grouping of A. muscaria, rather than a distinct species.

Sedum multiceps, also known as miniature/pygmy Joshua tree, is a perennial, deciduous species of Sedum from the succulent plant family Crassulaceae, native to Algeria. The plant is nicknamed for its glaucous leaves that grow in clusters, resembling Yucca brevifolia. It was named officially as a distinct species in 1862.

The black-crowned white-eye (Zosterops atrifrons) is a songbird species. It is closely related to the Old World babblers, and its family Zosteropidae might better be included in the Tiimalidae. Its subspecies from the Sulawesi region might warrant recognition as distinct species Z. subatrifrons. The Sangihe white-eye (Z.

MONITORS OF THE WORLD 1998 LIST. Kingsnake.com It is largely arboreal and extremely shy. The Northern Sierra Madre monitor lizard was thought to be of same species with Gray's monitor until a research concluded in 2010 that northern populations of Gray's monitor was a distinct species, now known as V. bitatawa.

Until the 1990s and early 2000, Noturus crypticus and Noturus fasciatus were thought to be the same species as Noturus elegans. However, they are now considered distinct species. The chucky madtom, N. crypticus, is the only one of the three currently listed as severely threatened.Burr, B.M., And Walter W Dimmick. 1981.

The Turkestani long-eared bat, Otonycteris leucophaea, is a species of bat found in Asia. Though it was initially described in 1873 as a species, for many years it was considered synonymous with the desert long-eared bat, Otonycteris hemprichii. Recently, it was recognized as a distinct species once again.

In this case, divergence is facilitated by the absence of gene flow. Parapatric speciation is the evolution of geographically adjacent populations into distinct species. In this case, divergence occurs despite limited interbreeding where the two diverging groups come into contact. In sympatric speciation, there is no geographic constraint to interbreeding.

The Tatama tapaculo (Scytalopus alvarezlopezi) is a species of bird in the family Rhinocryptidae. It is endemic to western Colombia. Its natural habitat is subtropical or tropical moist montane forest. It is considered a distinct species by the IOC, but the American Ornithological Society has yet to recognize the bird.

They feed on zooplankton, especially the larvae of copepods and crustaceans. They will dart into holes when alarmed. The populations of this species from the western Indian Ocean have been recognised by some workers as a distinct species, Nemateleotris exquisita, however, the validity of this taxon needs more taxonomic research.

Sympetrum semicinctum is closely related to, and may not be a distinct species from, the western meadowhawk (Sympetrum occidentale). Other geographical variants are S. californicum and S. fasciatum. BugGuide Pilgrim, E.M. and C.D. von Dohlen. 2007. Molecular and morphological study of species- level questions within the dragonfly genus Sympetrum (Odonata: Libellulidae).

Fishing is another common activity. There are many distinct species of fish in the oceans surrounding Christmas Island. Snorkeling and swimming in the ocean are two other activities that are extremely popular. Walking trails are also very popular, for there are many beautiful trails surrounded by extravagant flora and fauna.

The São Tomé ibis (Bostrychia bocagei), also known as the dwarf olive ibis, is a critically endangered bird that is endemic to São Tomé off the western coast of Central Africa. Once thought to be a subspecies of the larger olive ibis, it is now classified as a distinct species.

It is distinguished from the species Calotes liocephalus and similar lizards (C. ceylonensis, C. desilvai, C. liolepis, C. nigrilabris) in lacking spines on the head. It is distinguished from C. liocephalus by midbody scale count and body crest. It originally included the species now described as a distinct species, Calotes aurantolabium.

The plateau spotted whiptail (Aspidoscelis septemvittatus) is a species of lizard found in the southern United States in Texas, and in northern Mexico in Chihuahua and Coahuila. It is known to hybridize with the Eastern Spotted Whiptail, Cnemidophorus gularis, but is considered to be a distinct species due to phenotypic characteristics.

Streptomyces turgidiscabies is a streptomycete bacterium species, causing scab in potatoes. It has flexuous spore, the latter which are cylindrical and smooth. The type strain is SY9113T (= ATCC 700248T = IFO 16080T). It is almost identical to Streptomyces reticuliscabiei, however they are considered distinct species given the diseases they cause are different.

The dorsal coloration is variable—uniform straw brown to dark brown or with irregular dark spots and orange-yellow flanks. A pale stripe often runs down the middle of the back. A population in the northeastern Free State, South Africa has distinct dark lateral stripes and may represent a distinct species.

Opheodrys is a genus of small to medium-sized non-venomous colubrid snakes commonly referred to as green snakes. In North America the genus consists of two distinct species. As their common names imply, the rough green snake has keeled dorsal scales, whereas the smooth green snake has smooth dorsal scales.

BMC Evolutionary Biology, 12(1), 73., doi:10.1186/1471-2148-12-73. V. australe would therefore be considered a distinct species under the phylogenetic species concept. Viburnum australe and V. ellipticum are closely related to three species from eastern North America: V. rafinesqueanum, V. molle, and the endangered V. bracteatum.

The pygmy slow loris (N. pygmaeus) occurs east of the Mekong River in Yunnan, Laos, Vietnam, and Cambodia. The Bornean slow loris (N. menagensis), found on Borneo and nearby islands, including the Sulu Archipelago, and in 2012 was split into four distinct species (adding N. bancanus, N. borneanus, and N. kayan).

Nepenthes of Borneo. Natural History Publications (Borneo), Kota Kinabalu. while others consider them to be two distinct species, with plants commonly referred to as N. stenophylla actually representing N. fallax. As in Matthew Jebb and Martin Cheek's 1997 monograph and Charles Clarke's 1997 monograph, the first interpretation is followed here.

Amanita persicina was formerly believed to be a subspecies of Amanita muscaria, commonly known as fly agaric, and it was classified as A. muscaria var. persicina. Recent DNA evidence, however, has shown Amanita persicina to be a distinct species, and it was elevated to species status in 2015 by Tulloss & Geml.

The Maghreb barbel (Luciobarbus maghrebensis) is a ray-finned fish species in the family Cyprinidae. It is found in Morocco. The taxonomy and systematics of the Maghreb barbs are subject to considerable dispute. Some authors consider L. maghrebensis a distinct species, while others include it in the Algerian barb (L. callensis).

Although previously considered a subspecies of barred owl, the fulvous owl is now considered a distinct species. The barred owl was first described by Philadelphia naturalist Benjamin Smith Barton in 1799. The species was named due to the varied directions the dusky markings take on their underside.Barton, B. S. (1883).

The palm forest tree frog, Leptopelis palmatus, is a species of frog in the family Arthroleptidae endemic to the Príncipe island, in São Tomé and Príncipe. Red tree frog Leptopelis rufus from the African mainland was for a long time included in this species, but is now considered a distinct species.

Bolletino del Museo Civico di Storia Naturele di Venezia 28: 8592., though most commonly considered a distinct species. It is a member of the subgenus Koptortosoma, which is the largest Xylocopa subgenus and is widely distributed with over 200 species. Koptortosoma is polyphyletic and constitutes a sister lineage of Mesotrichia.

Bristish Ascomycètes. Ed. Cramer, Vaduz. p. 585. while at the same time several forms and varieties of M. vulgaris itself have been described. An extensive phylogenetic and nomenclatural study by Richard and colleagues in 2014, confirmed the status of Morchella vulgaris as a distinct species, and resolved several of its synonymities.

PCR-based assays have provided evidence that the Ohio variant and California variant of H. felis are in fact distinct species, M. haemofelis and Ca. Mycoplasma haemominutum respectively. A third Haemoplasma, Mycoplasma turicensis, was later identified in domestic cats. Haemoplasma species have also been identified in dogs (M. haemocanis), mice (M.

Its taxonomic status is disputed by different authors. Some treat Cupressus pigmaea as a distinct species, following Sargent, including Wolf (1948), Griffin & Critchfield (1976),Griffin, J. R., & Critchfield, W. B. (1976). The Distribution of Forest Trees in California. USDA Forest Service Research Paper PSW-82. Lanner (1999),Lanner, R. M. (1999).

Partly because of this confusion the species was often frequently confounded with Pinctada imbricata and Pteria colymbus. the Western Atlantic’s main Pteriidae representatives. Recent efforts to classify Western Atlantic bivalves have confirmed Pinctada longisquamosa as a distinct species and supported its transfer from the genus Pteria to the genus Pinctada.

In the present, M. fulvum is still referred to as part of the Microsporum gypseum complex. This complex includes the three distinct species: Microsporum gypseum, Microsporum fulvum and Microsporum incurvatum. Each of these fungi possess a high degree of morphological similarity but do have significant genetic differences accounting for the speciation.

Manipal University Press (MUP), India. His research paved the way in splitting the silvered langur into two genetically distinct species, the Indochinese silvered (T.germaini) and Annamese silvered (T.margarita)[23,24]. Nadler and co-workers discovered a new crested gibbon species, the northern yellow-cheeked gibbon (Nomascus annamensis) in 2010.[25]25\.

Nepenthes × pangulubauensis (; from Mount Pangulubau) is a natural hybrid between N. mikei and N. gymnamphora (or N. xiphioides, depending on whether it is considered a distinct species). It is endemic to the Indonesian island of Sumatra.McPherson, S.R. & A. Robinson 2012. Field Guide to the Pitcher Plants of Sumatra and Java.

The Egyptian weasel is so similar to the least weasel (M. nivalis) that only in 1992, it was suggested to be a separate species. However, results of a phylogenetic study indicate that mitochondrial DNA supports the Egyptian weasel to be a subspecies of Mustela nivalis rather than a distinct species.

Page 3 After a review of the previous literature, Maximowicz in St. Petersburg decided in 1883 For the details of the publication including the dates of the volumes and the reprint of the article in Mélange ... see the tree was a distinct species, and named it Prunus grayana after Asa Gray.

He renamed the Fiji bird as E. pealii in honour of its finder.Clements (1993) pp. 207–208 The Fijian common names kulakula and qiqikula are derived from "kula", red. The Fiji parrotfinch and the royal parrotfinch of northern Vanuatu are now again usually considered to be distinct species,Watling (2003) pp.

However, the extensive distribution of Z. c. intermedius (including S. Sulawesi, SE. Sulawesi, C. Lesser Sundas and small islands in between) is likely to contain more than one reproductively isolated population (cf. Z.c. intermedius and Z. c. flavissimus, with the latter now considered a distinct species, the Wakatobi white-eye (Z. flavissimus)).

Phellinus sulphurascens is the Douglas-fir species of the fungus genus, Phellinus. It was recently recognized as a distinct species from Phellinus weirii. Both were historically thought to be the same, but genetic tests suggested that the two species were distinct. The form first described as P. weirii is the Cedar form.

The species L. wurdemanni has undergone reclassification and has been divided into four distinct species – L. wurdemanni, L. ankeri, L. bahia and L. boggessii. More recent molecular phylogenetic work found that L. wurdemanni is a cryptic species with at least 5 (and potentially 9) morphologically identical species being present across its range .

A new species called the kiang (E. kiang), a Tibetan relative, was previously considered to be a subspecies of the onager as E. hemionus kiang, but recent molecular studies indicate it to be a distinct species, having diverged from the closest relative of the Mongolian wild ass's ancestor less than 500,000 years ago.

More specifically, homologous proteins that exist in two distinct species are called orthologs. Whereas, homologous proteins encoded by the genome of a single species are called paralogs. The phylogenetic relationships of proteins are examined by multiple sequence comparisons. Phylogenetic trees of proteins can be established by the comparison of sequence identities among proteins.

It was decided later in 1993 that Aecidium mori was a different, distinct species, and this taxonomic assignment was kept.Prasad, K., Dayakar Yadav, B. R., and Sullia, S. B. 1993. Taxonomic status of rust on mulberry in India. Curr. Sci. 65:424–426. All of these differ from the species of A. mori.

However, Shuangbaisaurus also possesses a groove between its premaxilla and maxilla, a characteristic which has been used to characterize Sinosaurus as a genus. Among the two morphotypes present within the genus Sinosaurus, Shuangbaisaurus more closely resembles the morphotype that is variably treated as a distinct species, S. sinensis, in its relatively tall skull.

First described by François Marie Daudin in 1802, these lizards were previously classed as a subspecies of Varanus exanthematicus, but have since been declared a distinct species based upon differences in hemipenal morphology.Bohme, W. (1991). New finding on the hemipenal morphology of monitor lizards and their systematic implications. Mertensiella, 2, 42-49.

Cortinarius subrubrovelatus is a species of fungus in the large mushroom genus Cortinarius (subgenus Phlagmacium). It was described as new to science in 2008 as a variety of Cortinarius glaucopus, but raised to distinct species status in 2014. The mushroom is found in Central and northern Europe, where it grows in coniferous forests.

Aquilegia barbaricina (also called barbaricina columbine) is a species of plant in the family Ranunculaceae. It is endemic to Italy, occurring only on the island of Sardinia. It is not entirely clear to some taxonomists whether this is a distinct species or a subspecies of some other Sardinian or other Mediterranean island columbine.

Emilia fosbergii has been collected in many places for many years, the specimens regarded as belonging to E. coccinia, E. sagittata, or E. javanica. A reexamination of a large number of specimens led Nicolson to recognize it as a distinct species in 1975. He named the species in honor of Francis Raymond Fosberg.

The native inhabitants of Utapau can be divided into two distinct species. The taller, more highly evolved Pau'ans have deeply lined, ash-colored faces, gaunt builds, and wear thick, tightly fitting clothes. The smaller Utai make up the working class. They have rounded faces with distended eyes, and have a short, stocky build.

Gynanisa maja, the speckled emperor or chipumi, is a moth of the family Saturniidae. The species was first described by Johann Christoph Friedrich Klug in 1836. It is known from South Africa to eastern Africa (up to Angola and Zambia). Gynanisa nigra is just a darker form and not a distinct species.

It is now accepted that the Australasian bent-winged bat and the Eastern bent-winged bat are two distinct species. The Australasian bent-wing bat has three subspecies: M. orianae bassanii (the southern bent-wing bat), M. o. orianae (the northern bent-wing bat), and M. o. oceanensis (the eastern bent-wing bat).

A 1998 IUCN assessment of Agathis dammara regarded Agathis borneensis as a synonym. IUCN assessor Aljos Farjon now treats A. borneensis as a distinct species. In his IUCN assessments of 1998 and 2010, Farjon assessed Agathis endertii as a separate species. However, as of 2013, he considers A. endertii synonymous with A. borneensis.

L. amboinesis was described and named by Johannes Govertus de Man, published in 1888. In the same year it was also described as Hippolysmata vittata var. amboinensis listing the shrimp as a variant within the species Lysmata vittata. These are now considered synonyms with L. amboinesis a distinct species from L. vittata.

A member of the northern oriole group, Bullock's orioles were once considered to be conspecific with Baltimore orioles and black-backed orioles. However, recent phylogenetic data suggest that Bullock's orioles are members of a distinct species that does not share a most-recent common ancestor with Baltimore orioles, as was once assumed.

Sinthusa kawazoei is a butterfly of the family Lycaenidae. It is endemic to the Philippines and found only on the island of Palawan. It was first described as a subspecies of Sinthusa privata distributed on Borneo.Sinthusa privata kawazoei H.Hayashi, 1976 Treadaway and Schroeder raised its status to a distinct species in 2012.

It is a rather distinct species of dacnis, formerly separated in the monotypic genus Pseudodacnis. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and plantations.

There is no support for their distinct species status from molecular data however.Lake Ohrid trouts Balkan trout restoration group. Downloaded on 19 May 2010. Salmo balcanicus specifically spawns from October to January at the outlet of the lake, Black Drin, in the northwestern end of the lake near the Macedonian-Albanian border area.

There are several purplish species in North America that were formally labeled as L. amethystina before Gregory M. Mueller described them as distinct species in 1984.Muller, 1984. Laccaria amethysteo- occidentalis is found in western North America, where L. amethystina does not occur. It is a very common mushroom in its geographical range.

Choerophryne valkuriarum is a species of frog in the family Microhylidae. It is endemic to the eastern New Guinea in Papua New Guinea and is known from near Wau in the Ekuti Dividing Range south to Myola in the Owen Stanley Range. The nominal species might consist of more than one distinct species.

The cobble skink is part of the speckled skink (Oligosoma infrapunctatum) complex, and when it was first listed as a distinct species in a field guide, based on morphological differences, although at the time there was no genetic evidence to support this. Subsequently, its distinct status has been confirmed by a genetic analysis.

What was initially believed to be a bony sternum turned out to be part of the coracoid, but a cartilaginous sternum may have been present. Only the front of its face is missing. It has been used as the basis for a distinct species, A. bavarica,Wellnhofer, Peter. Archaeopteryx. Der Urvogel Von Solnhofen.

There was a proposal to divide Pampas cat into three distinct species, based primarily on differences in pelage colour/pattern and cranial measurements. Accordingly, three species were recognised in the 2005 edition of Mammal Species of the World: the colocolo (L. colocolo), the Pantanal cat (L. braccatus), and the Pampas cat (L.

The tarsi are feathered to the base of the toes. The Colombian screech owl was formerly considered a distinct species, but is now considered conspecific. Its natural habitat is subtropical or tropical, moist montane forests, from elevations of . This relatively powerful bird is a strictly nocturnal bird that becomes active at dusk.

Aplochiton marinus is a species of fish in the family Galaxiidae. It is an amphidromous fish migrating between ocean and fresh water. A. marinus is endemic to Chile. FishBase lists A. marinus as a synonym of A. taeniatus (also reported in Argentina), but IUCN treats it as a distinct species of its own.

Haemanthus species are southern in distribution, form true bulbs and have 2n = 16 chromosomes, whereas Scadoxus species, such as S. longifolius, are found throughout tropical Africa, do not all form bulbs and have 2n = 18 chromosomes. Scadoxus longifolius appears to be closely related to Scadoxus cinnabarinus and may not be a distinct species.

Papilio nubilus is a rare species of swallowtail butterfly from the genus Papilio that can be found in Borneo.Papilio at Funet Previously listed as a distinct species ( D'Abrera 1982, Munroe 1961), but now regarded (by Collins & Morris 1985, Tsukada & Nishiyama 1982: 307) as an interspecific hybrid between Papilio nephelus and Papilio polytes.

Poecilotheria subfusca, or the ivory ornamental, is a spider in the tarantula family, Theraphosidae. It is endemic to Sri Lanka. , the World Spider Catalog regarded Poecilotheria bara as a synonym. Other sources, particularly in the pet trade, have treated highland and lowland forms as distinct species, with the lowland forms being P. bara.

The Cape Verde buzzard (Buteo bannermani) is a medium to large bird of prey that is sometimes considered a subspecies of the widespread common buzzard (Buteo buteo). As its name implies, it is native to Cape Verde . Some taxonomists consider it to be a distinct species and is treated as such here.

227, table 2 Since then, the two have generally been retained as distinct species, as supported by further research; a 1994 study even found the two to occur at some of the same places (in sympatry) in southern Texas and nearby Tamaulipas, Mexico.Schmidt and Engstrom, 1994, p. 419; Musser and Carleton, 2005, p.

Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist shrubland. It is threatened by habitat loss. Some taxonomists consider this to be a subspecies of the dusky megapode, others as a subspecies of the orange-footed scrubfowl, but is increasingly looked at as a distinct species.

C. cercyon Nicev. (59e) has the markings quite similar to [saka Moore form of Calinaga buddha] -, but the ground is yellowish; moreover, the position of the distal spots of the forewing is somewhat different, so that we apparently have to do with a distinct species.— West China: Ta-tsien-lu.Seitz, A. ed.

The Nilgiri clouded yellow, Colias nilagiriensis, is a small butterfly native to southern India. It belongs to the family Pieridae. Some authors treat this as a subspecies of the eastern pale clouded yellow (C. erate) while others consider it on the basis of its geographic isolatation as a phylogenetically distinct species Colias nilagiriensis.

It is possible that the Queensland populations currently included as Endiandra virens between Caboolture and Kin Kin represent a distinct species once named Endiandra lowiana by F. M. Bailey in 1892. These plants differ in leaf and bark characters from the NSW populations and are similar to a less hairy Endiandra pubens while NSW plants are quite dissimilar to E. pubens. The type specimen of Endiandra lowiana is from Maroochie (Yandina), While the type for Endiandra virens is from the Clarence River see (APNI) thus should the QLD populations prove to be a distinct species they would be called Endiandra lowiana while NSW populations would retain the name Endiandra virens genetic and more detailed morphological studies would help to clarify the status of these two taxa.

HHV-6A and HHV-6B were recognized by the International Committee on Taxonomy of Viruses (ICTV) as distinct species in 2012. Human Roseoloviruses include HHV-6A, HHV-6B and HHV-7. Herpesvirus was established as a genus in 1971 in the first report of the ICTV. This genus consisted of 23 viruses among 4 groups.

The bat was formerly considered a subspecies of H. cineraceus by Blyth in 1853 , but is now commonly considered a distinct species. The species was first recognized as a separate species by Topál in 1975. It belongs to the bicolor species group. The holotype was collected from the Jabalpur district of Madhya Pradesh in 1970.

The holotype was collected by T. S. Jones of the Sierra Leone Department of Agriculture in Makeni in 1947. Upon further examination of the holotype at the British Museum by Hayman, it was recognized as a distinct species. The bat was subsequently named after T. S. Jones. It belong to the bicolor species group.

R. swinnyi is in the same family as R. denti and R. simulator. These species have very similar body structure, size, morphology and echolocation calls. This led scientists to the conclusion that R. swinny was a subspecies of R. denti and R. simulator. Genetic studies have shown that R. swinnyi is a separate, distinct species.

However, little evidence of hybridisation actually occurring has been found. Although there have been reports of frogs of mixed appearance in Gippsland, analysis of proteins and sera of the frogs showed two distinct species. Samples in other area of distribution have shown no evidence of hybridisation in spite of cohabitation.Pyke and White, p. 569.

Associazione Italiana Piante Carnivore. This last species had previously been confused with the ultrahighland N. lamii; its recognition as a distinct species necessitated the publication of a revised circumscription for N. lamii. The work also includes an emended description of N. thorelii, which was rediscovered in 2011 after more than 100 years.Mey, F.S. 2012.

The spotted great rosefinch or spotted rosefinch (Carpodacus rubicilla severtzovi) is a finch in the family Fringillidae. It is found in Kashmir, Nepal, Tibet, and southwestern China. Its natural habitats are tundra and temperate grassland. It was formerly considered a distinct species, but is now commonly regarded as a subspecies of the great rosefinch.

L. sphaericus has five homology groups (I-V), with group II further dividing into subgroups IIA and IIB. Due to the low levels of homology between groups, it has been suggested that each might represent a distinct species, but owing to a lack of research on this topic, all remain designated as L. sphaericus.

Hedera iberica is a species of ivy (genus Hedera) which is native to the western Iberian peninsula (Portugal and southwest Spain), and northern Morocco. It was formerly classified as a sub-species named Hedera maderensis iberica in Hedera maderensis (K. Koch ex A. Rutherf). The Iberian subspecies was subsequently classified as a distinct species.

It is debated whether Denisovans represent a distinct species of Homo or are an archaic subspecies of H. sapiens. DNA analyses showing Denisovans as a sister taxon of Neanderthals also concerns the classification of the latter as H. neanderthalensis or H. s. neanderthalensis. Proposed species names for Denisovans are H. denisova or H. altaiensis.

It can also be found in the aquarium trade. Although considered a subspecies of Bodianus bilunulatus in the past, it is now treated as a distinct species in its own right.Gomon, M.F., 2006. A revision of the labrid fish genus Bodianus with descriptions of eight new species. Rec. Aust. Mus. Suppl. 30:1-133.

Its common name is maiden's quiver tree. Its habitat may be threatened by mining and overgrazing. It is similar to Aloidendron dichotomum, but bushier and shorter in stature, rarely exceeding 60 centimeters in height. It might not be a distinct species; it has been treated as a variety and a subspecies of A. dichotomum.

Atoposaurus is an extinct genus of crocodylomorph. It is the type genus of the family Atoposauridae. Fossils have been found that were Late Jurassic in age from two distinct species in France and Germany. One interesting feature of Atoposaurus is that it lacked dorsal scutes, a common characteristic of atoposaurids as well as most crurotarsans.

Zverkov & Efimov (2019) considered the genus Cryopterygius to be a junior synonym of the genus Undorosaurus. The authors considered the type species of the former genus, C. kristiansenae, to be synonymous with Undorosaurus gorodischensis; second species of Cryopterygius, C. kielanae, was tentatively maintained by the authors as a distinct species within the genus Undorosaurus.

Erigeron klamathensis is a North American species of flowering plant in the daisy family known by the common name Klamath fleabane. It had been collected by botanists for many years and generally regarded as part of the species E. foliosus. It was not recognized as a distinct species until 2004.Newom, Guy L. 2004.

The Madagascan cuckooshrike (Ceblepyris cinereus), also known as the ashy cuckooshrike, is a species of bird in the family Campephagidae.

Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.

The Kabobo apalis (Apalis kaboboensis) is a species of bird in the family Cisticolidae. It is endemic to the Itombwe Mountains in eastern Democratic Republic of the Congo. Its natural habitat is tropical moist montane forests. Originally described as a distinct species, it was later treated as a subspecies of the chestnut-throated apalis.

The chestnut-throated apalis (Apalis porphyrolaema) is a species of bird in the cisticola family Cisticolidae. The Kabobo apalis, originally described as a distinct species, is usually treated as a subspecies A. p. kaboboensis of the chestnut-throated apalis today. It is itself sometimes considered to be the same species as the Chapin's apalis.

The disparity between the maturation size and the maximum size is usually large for a cartilaginous fish, and it is possible that the specimens currently identified as the Coral Sea stingaree actually represent distinct species, one large and one small. However, the presumed large and small forms cannot be distinguished by morphological or meristic traits.

The fungus was first described in 1836 by Czech mycologist Julius Vincenz von Krombholz, who considered it to be a variety of Boletus sanguineus.Krombholz JV von. (1836). Naturgetreue Abbildungen und Beschreibungen der Schwämme. 5: 1-17 In 1925, it was recombined as a distinct species by German mycologist Franz Joseph Kallenbach,Kallenbach FJ. (1925).

The Cape parrot (Poicephalus robustus) or Levaillant's parrot is a large, temperate forest dwelling parrot of the genus Poicephalus endemic to South Africa. It was formerly grouped as a subspecies along with the savanna- dwelling brown-necked parrot (P. fuscicollis fuscicollis) and grey-headed parrot (P. f. suahelicus), but is now considered a distinct species.

372–385) summarized previous discussions of the problem and concluded that the right- and left-handed populations were distinct species. Others have stated that these populations were not distinct, and the question is far from settled. The Peruvian clausiliid, Nenia callistoglypta Pilsbry (1949, pp. 216–217), also has been described as being an amphidromine species.

Cope conceded in 1875 that Marsh's names did have priority over his, but maintained that Pterodactylus umbrosus was a distinct species (but not genus) from any that Marsh had named previously.Cope, E.D. (1875). "The Vertebrata of the Cretaceous formations of the West." Report, U. S. Geological Survey of the Territories (Hayden), 2: 302 pp.

Isthmohyla lancasteri was described by Thomas Barbour in 1928, based a single specimen (the holotype) collected by C. R. Lancaster—and after whom the species is named. The species is very variable; however, high-altitude populations that were first ascribed to this species were in 1996 recognized as a new, distinct species, Isthmohyla calypsa.

Parnassius staudingeri hunza, the Karakoram banded Apollo, is a high-altitude butterfly which is found in India. It is a member of the genus Parnassius of the swallowtail family, Papilionidae. It was variously treated as a subspecies of P. delphius and a distinct species. The subspecies was first described by Grigory Grum-Grshimailo in 1888.

This species was described from Misaki, Sagami Bay, on an Obelia colony, Japan. Additional specimens included in the original description were from Sargassum plants at Mukaishima, Seto Inland Sea. The species has been reported from British Columbia, but it is likely that several distinct species are involved.Rudman, W.B., 2001 (March 6) Eubranchus misakiensis Baba, 1960.

It is found south of Congo River and west of Lomami River. It had once been considered a subspecies of the P. badius. It was recognised as a distinct species by Dandelot in 1974, and this was followed by Groves in 2001, while others have suggested it should be considered a subspecies of P. rufomitratus.

The hen harrier (Circus cyaneus) is a bird of prey. The genus name Circus is derived , referring to a bird of prey named for its circling flight. The specific cyaneus is Latin, meaning "dark-blue". While many taxonomic authorities split the northern harrier and the hen harrier into distinct species, others consider them conspecific.

2007 (2nd edition). World Atlas of Marine Fishes. The recent precedents of the recognition of A. barberi as a distinct species from A. melanopus and A. pacificus being distinguished from A. akallopisos demonstrate the need to show not only geographic and morphological differences, but also genetic data to confirm the separation of the proposed species.

Its closest relatives are probably the brown fulvetta, and the black-browed fulvetta which was only recently recognized as a distinct species again. The Javan fulvetta and the Nepal fulvetta might also belong into this group.(Pasquet et al. 2006) The brown-cheeked fulvetta is a resident breeding bird in Bangladesh, India and Southeast Asia.

The cryptic forest falcon is a member of the family Falconidae, which includes falcons and caracaras. It is a member of the genus Micrastur, which encompasses all forest-falcons. It is a monotypic species. Specimens were historically labeled as lined forest falcons, until the cryptic forest falcon was recognized as a distinct species in 2002.

Meddelelser fra Carlsberg Laboratoriet 2: 29–102. but in actuality it was not officially described by Hansen as a distinct species until 1908, along with another synonym, Saccharomyces monacensis..Hansen, E. C. 1908. Recherches sur la physiologie et la morphologie des ferments alcooliques. XIII. Nouvelles etudes sur des levures de brasserie a fermentation basse.

In 2003, Japanese scientists announced the discovery of a new species of rorqual, named Omura's whale (Balaenoptera omurai), after extensive studies of Bryde's whale (B. brydei). The scientists also claimed their research settled a long-standing taxonomic argument, and Bryde's whale and the pygmy Bryde's whale (B. edeni) are in fact two distinct species.

A number of other species (K. matschiei, K. multituberculata, K. tavetana, K. uluguruensis, and K. vosseleri ) have been mistakenly called by this species' name or classified as subspecies. In 2008, it was shown that they actually are their own, distinct species. The true Fischer's chameleon is rare with a more restricted distribution than previously believed.

Eurycea tonkawae is the sister taxon to E. naufragia and E. chisholmensis, two other endemic perrenibranchiate central Texas salamanders. Its natural habitats are freshwater springs, spring runs, and wet caves of the Buttercup karst system. Cave dwelling E. tonkawae may represent a distinct species, however further work is needed to clarify their taxonomic status.

Chiromantis petersii is a species of frog in the family Rhacophoridae. It is found in Kenya and Tanzania and is broadly distributed in the inland areas of both countries. Chiromantis kelleri was previously considered subspecies of Chiromantis petersii, but is currently recognized as a distinct species. These two species are sympatric in northern Kenya.

In 1939 the Belgian malacologist William Adam examined the specimens of Sepioteuthis recovered from the tropical western Pacific. He synonymised the twelve species then considered valid under Sepioteuthis lessoniana. A study in 1993 by Segawa et al. revealed that the population of S. lessoniana in Okinawa may actually be composed of three distinct species.

Formally described by Derek Reid in 1972 as a variety of Hygrophoropsis aurantiaca, it was raised to distinct species status by Thomas Kuyper in 1996. Hygrophoropsis pallida (Peck) Kreisel is a synonym that was never formally published. It is based on Charles Horton Peck's taxon Cantharellus aurantiatus var. pallidus, which he published in 1896.

Judiceratops is a basal chasmosaurine. It is more primitive than most genera within the subfamily with the exception of Mercuriceratops. The below cladogram follows Longrich (2015), who named a new species of Pentaceratops, and included nearly all species of chasmosaurine. Despite the fragmentary nature of the fossils, they can be identified as a distinct species.

Isocetus was considered a nomen dubium by Steeman (2010) but was treated as a distinct species by Bisconti et al. (2013) based on characters of the mandibular condyle and dentary. A complete thalassothere specimen from Belgium previously assigned to Isocetus depauwi by Abel (1938) is now the holotype of the species Parietobalaena campiniana.O. Abel. 1938.

New Rodents (Mammalia: Cricetidae, Muridae) from Iran and Pakistan. Proceedings of the Biological Sciety of Washington, 86:163-174. The animal is found in the region near Teheran and is identifiable based on its large size (74–91 mm) and soft, buffy, brown dorsal pelage. Musser and Carleton recognized C. grandis as a distinct species.

52 plates. LCCN 89-50342. . is a venomous pitviper species endemic to Sri Lanka where it is known as මූකලන් තෙලිස්සා (mukalan thelissa) in Sinhala. Earlier thought that Hypnale walli and Hypnale nepa were two distinct species, but it is now accepted that it is the same species and Hypnale walli is a synonym name.

The white-browed crombec (Sylvietta leucophrys) is a species of African warbler, formerly placed in the family Sylviidae. The enigmatic Chapin's crombec might be a distinct species, or a subspecies Sylvietta leucophrys chapini of the present species. The white-browed crombec is found in Burundi, Democratic Republic of the Congo, Kenya, Rwanda, Tanzania, and Uganda.

The Korean brown frog has earlier mostly been considered as subspecies of Rana amurensis, that is, R. a. coreana. However, morphological and genetic analyses support its status as a distinct species, though closely related to R. amurensis. The boundary between these two species is unclear. Until recently, Korean brown frog was considered Korean endemic.

Like other members of the genus Aspergillus, the A. ustus group is affiliated with the family Trichocomaceae. A phylogenetic study of Aspergillus section Usti using morphology, secondary metabolite chemistry and gene sequencing (beta-tubulin and calmodulin) revealed 21 distinct species and showed an affiliation of the section with two teleomorph genera, Emericella and Fennellia.

Cabanis's wren (Cantorchilus modestus) is a species of bird in the family Troglodytidae. It is found in Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua. It was considered conspecific with the canebrake wren and the isthmian wren, together called the plain wren. It is considered as a distinct species because of different vocalizations and genetic divergence.

Whether A. chinensis and A. rubra were distinct species or synonyms was a controversial issue for botanists throughout the 20th century, with current consensus favoring the latter interpretation. The plant once known as Astilbe davidii (Franch.) is today regarded as a variety of A. chinensis. Other varieties include A. chinensis var. divaricata (Nakai) and A. chinensis var.

The stripe-breasted rhabdornis (Rhabdornis inornatus), also known as the stripe-breasted creeper or plain-headed creeper, is a species of bird currently placed in the starling family, Sturnidae. It is endemic to the southern and central Philippines. The Visayan rhabdornis is now usually considered a distinct species, where previously it was considered a subspecies. The grand rhabdornis (R.

Early botanical collectors of this taxon include Ferdinand von Mueller and Frederick George Waterhouse. Mueller regarded it as a distinct species, provisionally labelling it A. barbata in his herbarium, but publication fell to George Bentham, who regarded it as merely a variety of A. sericea (now A. sericeus). In 1870. Bentham published it as A. sericea var.

Since the late nineteenth century, paleontologists had been naming new species of extinct North American amphisbaenians on the basis of single fragmentary specimens that often preserved too few anatomical features to support their status as distinct species. By synonymizing many of these species, Hembree showed that rhineurid diversity in North America was lower than once thought.

There is complete intergradation between them in belly color and they do not seem to differ vocally. Another yellow- bellied (occasionally white-bellied) and on average shorter-tailed, vocally distinct species, the Straneck's tyrannulet, was for a period mistakenly referred to by the scientific name Serpophaga griseiceps, but that name is a junior synonym of Serpophaga munda.

Cervus (Dama) mesopotamicus was described by Victor Brooke in 1875 for a deer that was shot at the Karun river in Iran. Its taxonomic status is disputed. It has traditionally been considered to be a subspecies of the fallow deer from western Europe, Dama dama, but is also treated as a distinct species by some authors.

This species is also known by several alternate names, such as amberjack, forktail, mossback, white salmon and yellowtail tunis or tuna California Yellowtail, Retrieved August 2009 or by its Spanish name jurel. Although previously thought to belong to S. lalandi, recent genetic analysis distinguished California yellowtail (S. dorsalis) as a distinct species from Yellowtail amberjack (S. lalandi).

Over time, the number has been reduced to less than a thousand. A modern and comprehensive study of Salvia species was done by Gabriel Alziar, in his Catalogue Synonymique des Salvia du Monde (1989) (World Catalog of Salvia Synonyms). He found that the number of distinct species and subspecies could be reduced to less than 700.Clebsch, p. 18.

They are often, but not always, sweet- scented.In the past, scented plants were sometimes treated as the distinct species N. odorum, but the character is not constant and it is no longer regarded as a separate taxon. The fruit is a long narrow pair of follicles long, which splits open at maturity to release numerous downy seeds.

The Mindanao miniature babbler (Micromacronus sordidus) is a bird species in the family Cisticolidae. It was formerly included in M. leytensis as a subspecies, is now usually held to be a distinct species, M. sordidus. M. sordidus is endemic to the Philippines. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.

Olson, D. M. & E. Dinerstein (1998). The Global 200: A representation approach to conserving the Earth's most biologically valuable ecoregions. Conservation Biol. 12:502–515. The concept of ecoregion applied by Bailey gives more importance to ecological criteria and climate, while the WWF concept gives more importance to biogeography, that is, the distribution of distinct species assemblages.

The Chin Hills wren-babbler (Spelaeornis oatesi) is a bird species in the family Timaliidae. It was until recently considered a subspecies of the long- tailed wren-babbler; the IUCN for example started recognizing it as distinct species in 2008.BLI (2008) It is found in India and Myanmar. Its natural habitat are subtropical or tropical moist montane forests.

Uncinia is a "satellite genus" of the very large genus Carex, alongside other satellites such as Cymophyllus, Kobresia, Schoenoxiphium, Vesicarex. Uncinia seems to form a monophyletic group, with the most distinct species being U. kingii, a species which has sometimes been placed in the genus Carex. Similarly, Carex microglochin has sometimes been included in Uncinia, as U. microglochin.

Around 5000 specimens from twenty-one distinct species are represented at Xujiayao. The large majority of the remains belong to Przewalski's horse and Equus hemionus. The next most common remains belong to Coelodonta, Spirocerus (Xujiayao antelope/Spirocerus hsuchiayaocus and Pei's antelope/Spirocerus peii), Procapra and Gazella. Some red deer, sika deer and pig remains were also found.

Henderson and coauthors report that the species was probably present throughout the Lesser Antilles, but was extirpated on many of them. George Proctor (in Acevedo-Rodríguez & Strong, 2005 ) considers Coccothrinax alta to be a distinct species (based on its shorter, more slender trunk, fewer stamens and much smaller fruit, but Rafaël Govaerts considers it a synonym of C. barbadensis.

Distinguishing close species within a complex requires the study of often very small differences. Morphological differences may be minute and visible only by the use of adapted methods, such as microscopy. However, distinct species sometimes have no morphological differences. In those cases, other characters, such as in the species' life history, behavior, physiology, and karyology, may be explored.

Great Basin Naturalist. 33, 2: 120-122. When it was finally found, Eriogonum expert James L. Reveal examined it in the field, compared it to the similar buckwheat Eriogonum contortum, and named it as a new species in 1973. Recent genetic analysis confirms that these two species and Eriogonum clavellatum are indeed similar but are 3 distinct species.

Glochidion sumatranum known as the umbrella cheese tree is a plant in the family Phyllanthaceae. Although recognized as a distinct species by some sources, others include it within Glochidion zeylanicum. It is found in northern and eastern Australia, New Guinea and Indonesia. The habitat is rainforest, or rainforest margins in swampy areas, sometimes associated with palms.

Opuntia ammophila, the devil's-tongue, is a species of prickly pear cactus in Florida. Individuals typically occur singly and do not generally form dense thickets. O. ammophila was once considered a variety of O. humifusa; however, it is a distinct species. Among their many differences, O. ammophila has gray- green cladodes rather than green or grass-green.

However interspecific crosses are well documented.RoyChowdhury 2006 There are tri- hybrids and quad-hybrids being produced (crossing 3 or 4 distinct species). Such work indicates that complex hybrids should be possible. One constraint remains that seedlings may still carry the apomictic trait, and it is necessary to have progeny from a test cross to determine this.

Sea Challengers, Monterey, California, page 93. Similar looking animals from the White Sea and Barents Sea, North Atlantic have been demonstrated to be a distinct species, Dendronotus niveus.Ekimova, I.; Korshunova, T.; Schepetov, D.; Neretina, T.; Sanamyan, N.; Martynov, A. (2015). Integrative systematics of northern and Arctic nudibranchs of the genus Dendronotus (Mollusca, Gastropoda), with descriptions of three new species.

The dogs were sent to Sir Edward Hallstrom who had set up a native animal study center in Nondugi, and from there to the Taronga Zoo in Sydney, Australia. In 1957, Ellis Troughton examined the two singing dog specimens from the Taronga Zoo and classified them as a distinct species Canis hallstromi in honour of Hallstrom.

Some authors maintain the some Chinese material also belongs to this species,Flora of China Vol. 24 Page 153 宽叶油点草 kuan ye you dian cao Tricyrtis latifolia Maximowicz but the World Checklist regards the Chinese populations as a distinct species, T. puberula.Kew World Checklist of Selected Plant Families, Tricyrtis puberula Further investigation seems warranted.

The Eunectes beniensis was initially believed to be the result of hybridization between the green and yellow anaconda, but was later determined to be a distinct species. Its taxonomic status is not clear due to lack of information and the similarity in appearance to Eunectes notaeus. It is closely related to Eunectes notaeus and Eunectes deschauenseei.

Finally, in the Middle Pleistocene local uplifts in the Pampean region separated the ancestors of E. moreni and E. puerulus, and the lowlands population, isolated form its relatives since more than one million years, began also expanding into the uplands, yielding E. (t.) bolsonensis which currently well on its way to become another highly distinct species.

435 and concluded that it was distinct enough to be classified as a separate species, Neoromicia malagasyensis.Goodman and Ranivo, 2004, p. 438 Two years later, Paul Bates and colleagues reported on two more specimens and showed that the bacula (penis bones) of N. malagasyensis and N. somalica are different, providing further evidence that they are distinct species.

A 2012 paper purporting to show that A. lianxianense was genetically nested within A. gravesii led the authors to suggest that, due to their genetic and morphological similarity, A. lianxianense should not be treated as a distinct species from A. gravesii. However, this specimen (J.-M. Lu 441, from Guangdong) was subsequently re- identified as A. mariesii.

Despite the abundance of fossil sites of the Pliocene and Pleistocene in South America, the remains of crocodilians of these periods are scarce and fragmentary and generally little studied. C. venezuelensis is one of the few findings confirmed of a distinct species of this period and may help clarify the history of this group after the Miocene.

Retrieved on 12 May 2006. However, recent studies have shown that these two taxa are distinct species. In 2001, Charles Clarke suggested a revised status of Vulnerable for N. longifolia based on the IUCN criteria. The habitat of this species may be threatened in the near future by fires deliberately started to clear forest for agricultural purposes.

Modern forestry research has identified five different taxa of P. ponderosa, with differing botanical characters and adaptations to different climatic conditions. Four of these have been termed "geographic races" in forestry literature. Some botanists historically treated some races as distinct species. In modern botanical usage, they best match the rank of subspecies and have been formally published.

Encelia resinifera was originally described as a variety of Encelia frutescens (Encelia frutescens var. resinosa) by M.E.Jones in 1913.Jones, Marcus Eugene ex Blake, Sydney Fay 1913. Proceedings of the American Academy of Arts and Sciences 49(6): 364 description in Latin, specimen listing in English In 1998 it was reclassified as a distinct species by Curtis Clark.

They are part of a complex, or a group of morphologically similar but biologically distinct species. These are called sibling species. B. tyroni has three sibling species: B. neohumeralis, B. aquilonis, and B. melas. All of these flies are sympatric, meaning that they inhabit the same territory, except B. aquilonas, which inhabits a different geographical area in northwest Australia.

These two species are considered together here. This section also acts as a tutorial for analysing bat calls. The only technical knowledge needed is that kHz is the number dialled into a bat detector. These two pips are distinct species but the frequencies of their calls are very variable and are not an exact indication of the species.

R. satarae has a long, soft coat with a golden brown back and white underside. Its tail is very long. It was originally described as a subspecies of the black rat (Rattus rattus) due to its similar appearance. However, DNA evidence has shown that they are two distinct species with no interbreeding despite them occupying the same habitat.

Two lower "canines" could distinguish D. sp. from D. hittoni, although it is possible that D. hittoni had two upper "canines" and the jaw fragment is simply from the upper jaw of D. hittoni. It is unclear then if D. sp. truly represents a distinct species or if it is simply a large specimen of D. hittoni.

Pycnoporus is a genus of fungi in the family Polyporaceae. This genus is distinguished from most other polypores because of its brilliant red-orange color. Modern mycology recognizes five distinct species of Pycnoporus: the type P. cinnabarinus, P. coccineus, P. palibini, P. puniceus, and P. sanguineus. These species are divided somewhat by morphology, biogeography, and DNA sequence.

The Ningbing false antechinus was first collected by Harry Butler at Ningbing, an abandoned station in the Kimberley region. It was long considered to be a form of the fat-tailed false antechinus (P. macdonnellensis), but was given distinct species status by D. J. Kitchener in 1988. Its common and species names honour the location of its discovery.

A 2010 study identified a Japanese species, previously identified as A. hygrometricus, as genetically distinct; it has yet to be officially named. A form of the species found in Korea and Japan, A. hygrometricus var. koreanus, was named by V.J. Stanĕk in 1958; it was later (1976) published as a distinct species—A. koreanus—by Hanns Kreisel.

The Colombian tinamou, Crypturellus erythropus columbianus, is a tinamou found in Córdoba, Sucre, Bolívar, and Antioquia in north-central Colombia.Clements, J (2007) Little is known about it. It occurs in lowland moist forest and shrubland at elevation up to . It is sometimes treated as a distinct species, and sometimes as a subspecies of the red-legged tinamou.

The species is named "gloveri" in honour of the late John Glover, a former Curator of Fishes at the South Australian Museum, who worked extensively on desert gobies and other taxa of fishes found in the deserts of Australia. Glover was sure that this goby was a distinct species from Chlamydogobius eremius but he did not describe it.

Acontias gracilicauda, the slendertail lance skink or thin-tailed legless skink, is a species of skink. It is found in the Republic of South Africa (Eastern Cape Province, Mpumalanga, Free State, North-West Province, Gauteng, KwaZulu-Natal) and Lesotho. Acontias namaquensis was formerly included in this species as a subspecies, but is now recognized as a distinct species.

Pterodontia misella is a species of small-headed flies (insects in the family Acroceridae). It is very close in appearance to Pterodontia flavipes, and was considered a synonym of it by Curtis Williams Sabrosky in 1948. However, this synonymy has not been adopted by later authors, and P. misella is still recognised as a distinct species.

Diarrhena americana, also known as American beak grass or American beakgrain, is a native, perennial bunchgrass of North America. Historically, Diarrhena americana was the only species of beak grass recognized in the United States; however studies have suggested that the known beak grass is to be classified into two distinct species, Diarrhena americana and Diarrhena obovata.

Mootnick and Groves stated that hoolock gibbons do not belong in the genus Bunopithecus, and placed them in a new genus, Hoolock. This genus was argued to contain two distinct species which were previously thought to be subspecies: Hoolock hoolock and Hoolock leuconedys. The ranges of the two species are unclear and may overlap, and intermediates may occur.

Adenomera martinezi is a species of frog in the family Leptodactylidae. It is endemic to Brazil and only known from its type locality, Cachimbo in southwestern Pará. Prior to its redelimitation by Carvalho and Giaretta in 2013, it was believed to be more widespread. The widespread taxon is now recognized as a distinct species, Adenomera saci.

This species was described by Rudolph Bergh in 1878 but considered to be a synonym of Doris verrucosa by von Ihering, 1886Ihering H. von (1886). Zur kenntnis der Nudibranchien der brasilianischen kuste. Jahrbücher der Deutschen Malakozoologischen Gesellschaft 13 (3): 223-240 and subsequent authors. A detailed anatomical comparison of these species concluded that they were distinct species.

This conclusion was based on an index from leaf-shape on seedlings grown from acorns. However, this theory has not achieved wide support, with current authors accepting Quercus laurifolia as a distinct species (e.g. Flora of North America). Known hybrids with Quercus laurifolia as one parent are with Q. falcata (Q × beaumontiana Sarg.), Q. incana (Q.

Ito, Y., Nr. Tanaka, C.-K. Kim, R. Kaul, D. C. Albach (2016) Phylogeny of Sparganium (Typhaceae) revisited: Non-monophyletic nature of S. emersum sensu lato and resurrection of S. acaule. Plant Systematics and Evolution 302(1): 129-135. This taxon was included within Sparganium emersum by Cook and Nicholls (1986) but was recently resurrected as a distinct species.

The fossil subspecies D. m. submajor lived during the Middle Pleistocene Riss glaciation (250,000 to 300,000 years ago) when it was found in Europe south of the ice sheet. It is sometimes treated as a distinct species, but did not differ significantly from the extant great spotted woodpecker, whose European subspecies are probably its direct descendants.

In July 2006, Clarke revisited wild populations of N. pilosa on Bukit Batu Lesung to confirm its status as a distinct species. Later that year he, together with Ch'ien Lee and Stewart McPherson, published the formal description of N. chaniana.Clarke, C.M., C.C. Lee & S. McPherson 2006. Nepenthes chaniana (Nepenthaceae), a new species from north-western Borneo.

Nepenthes macrophylla was known to grow on Mount Trusmadi for a long time prior to its description, although it was not initially considered a distinct species. Shortly after its discovery, it was lumped with ', a similar species from Kinabalu National Park. In his 1976 guide, Nepenthes of Mount Kinabalu, botanist Shigeo Kurata wrote:Kurata, S. 1976. Nepenthes of Mount Kinabalu.

The native Viola appalachiensis habitats includes rich moist woods, mountain coves, stream banks, sometimes in mowed areas such as forest roads. Its range is from Pennsylvania to North Carolina in the Appalachian Mountains. It is very rare. Some authors consider this to be the same species as V. walteri, but others argue for its recognition as a distinct species.

395–396 Race albiventris is found in the Andaman Islands and now usually considered a distinct species, the Andaman shama. Race interpositus from southwestern Asia-China to Myanmar, Thailand and the Mergui Archipelago. Southern China has race minor while mallopercnus is found in the Malay peninsula. Race tricolor is found in the Sumatra, Java, Banka, Belitung and Karimata islands.

The nominate form is found in Sri Lanka and has somewhat darker grey upperparts. The Burmese shikra A. b. poliopsis may represent a distinct species. The population on Car Nicobar Island, earlier treated as a subspecies butleri and that on Katchall Island, obsoletus are now treated as a sub-species within a full species, the Nicobar sparrowhawk (Accipiter butleri).

The brown guitarfish (Rhinobatos schlegelii) is a species of fish in the Rhinobatidae family. It is found in western Pacific of Taiwan and the Philippines. Its natural habitats are open seas, shallow seas, coral reefs, and estuarine waters. The Taiwan guitarfish (Rhinobatos formosensis) was formerly considered a distinct species, but is now considered a junior synonym.

The white-throated rail (Dryolimnas cuvieri) or Cuvier's rail, is a species of bird in the family Rallidae. It is found in the Comoros, Madagascar, Mayotte, and Seychelles. The nominate subspecies is found on Madagascar. A flightless subspecies (sometimes considered a distinct species), Dryolimnas (cuvieri) aldabranus (Aldabra rail), inhabits Aldabra, while the semi-flightless subspecies D. c.

The entire fruit body will slowly stain a reddish- brown color in response to bruising or aging. It remains unknown whether Amanita aestivalis is a distinct species from A. brunnescens, another similar Amanita with a comparable distribution. There are several other white-bodied amanitas with which A. aestivalis may be confused, including A. virosa, A. phalloides, and A. bisporigera.

The Cheoah Bald salamander (Plethodon cheoah) is a species of salamander in the family Plethodontidae endemic to the state of North Carolina in the United States. Its natural habitat is temperate forests and it is threatened by habitat loss. It was formerly considered a variant of the red-cheeked salamander until it was found to be a distinct species.

Pleurotus populinus, the aspen oyster mushroom, is a gilled fungus native to North America. It is found on dead wood of aspen and cottonwood trees (genus Populus). Although morphologically similar to Pleurotus ostreatus and Pleurotus pulmonarius, it has been shown to be a distinct species incapable of cross-breeding. P. populinus is reported to be edible.

There is substantial morphological variability evident in O. n. nigriplantare, and a shallow level of genetic differential between islands within the Chatham Islands indicating low gene flow between islands, but not speciation between islands. The level of genetic and morphological divergence between O. n. nigriplantare and Oligosoma nigriplantare polychroma might warrant their recognition as distinct species.

Similarly, dead wood, the habitat of the corticioid Russulaceae, is rare in many exploited forests and needs special management. Recent studies have found some traditional Russulaceae species to comprise several cryptic species (see Systematics and taxonomy: Species diversity). This may imply that distribution range and population size for each of such distinct species are smaller than previously thought.

Since it may be more closely related to the rhinoceros auklet than the other puffins, it is sometimes placed in the monotypic genus Lunda. The juveniles, due to their similarity to C. monocerata, were initially mistaken for a distinct species of a monotypic genus, and named Sagmatorrhina lathami ("Latham's saddle-billed auk", from sagmata "saddle" and rhina "nose").

Eligmodontia typus is a species of rodent in the family Cricetidae. It is found in Argentina and possibly also Chile. The northernmost population might represent a distinct species, E. bolsonensis, to which the common name highland gerbil mouse would apply. The lowland population would then be known as eastern Patagonian gerbil mouse or eastern Patagonian laucha.

Lampropeltis triangulum, commonly known as the milk snake or milksnake, is a species of kingsnake; 24 subspecies are currently recognized. Lampropeltis elapsoides, the scarlet kingsnake, was formerly classified as the subspecies L. t. elapsoides, but is now recognized as a distinct species. The subspecies have strikingly different appearances, and many of them have their own common names.

A broader concept of Barbus cyclolepis would include in the same species several other barbel taxa that others consider distinct species, i.e. Barbus sperchiensis (Sprechios barbel), Barbus strumicae (Strumica barbel) and Barbus waleckii (Vistula barbel). B. waleckii has however also been suggested to be a hybridogenic species, perhaps derived from common barbel B. barbus and B. carpathicus.

Athyrium angustum is known as the northern lady fern, native to northeastern North America. It was long included in the superspecies Athyrium filix-femina, but is now largely recognized as a distinct species. Athyrium angustum has a more southern counterpart, Athyrium asplenioides. This species, the southern lady fern, has a broader frond, especially at the base.

Fertile hybrids with Quercus robur named Quercus × rosacea are found wherever the two parent species occur and share or are intermediate in characters between the parents. Charles Darwin, in Chapter II of On the Origin of Species, noted that the sessile and pedunculate oaks had been described as both distinct species and mere varieties depending on the authority consulted.

Bifidobacterium animalis is a gram-positive, anaerobic, rod-shaped bacterium of the Bifidobacterium genus which can be found in the large intestines of most mammals, including humans. Bifidobacterium animalis and Bifidobacterium lactis were previously described as two distinct species. Presently, both are considered B. animalis with the subspecies Bifidobacterium animalis subsp. animalis and Bifidobacterium animalis subsp. lactis.

Distribution of 33 King cherry trees in Mt. Halla in Jeju Island in 1998. ★ and ▲ represent Natural Monument No. 156 and No. 159 respectively. King cherry (Prunus × nudiflora, 왕벚 wangbeoj, 왕벚나무 wangbeojnamu or 왕벚꽃 wangbeojkkoch) is a Korean native cherry tree originating from Jeju Island. It is a distinct species from Japanese native Yoshino cherry.

It is very likely that the range was more extensive in the past before extensive felling for the wood. The populations in mainland Asia were treated as a distinct species Taiwania flousiana by some botanists, but the cited differences between these and the Taiwanese population are not consistent when a number of specimens from each area are compared.

A study by Hammer et al. (2019) determined that specimens previously identified as P. macrocephalus are morphologically and ecologically distinct species, the now named Ptilotus xerophilus T.Hammer & R.W.Davis (arid central and western Australia) and Ptilotus psilorhachis T.Hammer & R.W.Davis (eastern Queensland). P. macrocephalus has cream-green coloured ovoid flower heads. As with other green-flowered Ptilotus species (e.g.

Other reasons such as gene flow interruption from "vicariate divergence" and fragmented populations due to climate instability have also been cited. Ring species also present an interesting case of the species problem for those seeking to divide the living world into discrete species. All that distinguishes a ring species from two separate species is the existence of the connecting populations; if enough of the connecting populations within the ring perish to sever the breeding connection then the ring species' distal populations will be recognized as two distinct species. The problem is whether to quantify the whole ring as a single species (despite the fact that not all individuals interbreed) or to classify each population as a distinct species (despite the fact that it interbreeds with its near neighbours).

In the 1990s, some authors came to regard A. carinata as a synonym of A. vernicosa, which is not as rare. The consensus now is to consider it a distinct species, but the merge made it less likely that the populations would receive attention as a rare taxon. It grows only on federal land. Mining activity threatens some of the populations.

Only three distinct species of Medusinites are known. They are similar to Protolyella in form and have an inner and outer ring. Specimens are typically 1–5 cm in diameter and the radius of its central disc is smaller than the width of the outer ring. They also have radial furrows and concentric circle features, but those details are not always preserved.

In 2007, remarkably well preserved fossils were exposed in fossil beds at La Voulte-sur-Rhône, south of Lyon in south-eastern France. Researchers from the University of Lyon discovered about 70 fossils from three distinct species in the 160-million-year-old Jurassic La Voulte . The find will help fill in an enormous gap in the history of these creatures.

The Gabela bushshrike (Laniarius amboimensis) or Amboim bushshrike is a bird in the family Malaconotidae. It is a reclusive and enigmatic bird, and it is not quite resolved whether it should better be considered a distinct species or a well-marked subspecies of Lühder's bushshrike. It is endemic to Angola. Its natural habitat is subtropical or tropical moist montane forests.

Because these males have reduced dorsal pigmentation, resulting a pearlescent white appearance, they have been dubbed "white sticklebacks". It is currently unknown whether they are a distinct species, or simply a morph of the common Atlantic stickleback. Infection with the cestode parasite Schistocephalus solidus causes a reduction in egg mass production or complete absence of eggs in female three-spined sticklebacks .

At least 248 species were originally described in this genus. For instance, the house sparrow has 12 species of Isospora. However, most species are little studied, and some authors doubt whether all should be recognized as distinct species. In 2005, all former Isospora species that infect mammalian hosts were reclassified as members of the genus Cystoisospora, a member of the Sarcocystidae family.

"Journal of Environmental Monitoring" 4(4): 473-476. In 2008, a taxonomic revision of western North American populations of this species was published, formally establishing them as a distinct species, Boletus rex-veris.

The taxonomy presented in Nepenthes of Borneo almost wholly agrees with that of Matthew Jebb and Martin Cheek's 1997 monograph, "A skeletal revision of Nepenthes (Nepenthaceae)". Clarke makes only two major revisions: restoring N. faizaliana as a distinct species and sinking N. borneensis in synonymy with N. boschiana.Kurata, S. 2002. Proceedings of the 4th International Carnivorous Plant Conference: 111–116.

They supported Charles Clarke's interpretation of N. borneensis and N. faizaliana in Nepenthes of Borneo, synonymising the former with N. boschiana and restoring the latter as a distinct species, separate from N. stenophylla.Kurata, S. 2002. Proceedings of the 4th International Carnivorous Plant Conference: 111–116. In addition, N. philippinensis, which the authors had previously considered a doubtful taxon, was treated as distinct.

The grey-bellied wren-babbler (Spelaeornis reptatus) is a bird species in the family Timaliidae. It was until recently considered a subspecies of the long- tailed wren-babbler; the IUCN for example started recognizing it as distinct species in 2008.BLI (2008) It is found in China (Yunnan), India (Arunachal Pradesh), Myanmar, and Thailand. Its natural habitat are subtropical moist montane forests.

Ogilby's duiker (Cephalophus ogilbyi) is a small antelope found in Sierra Leone, Liberia, Ghana, southeastern Nigeria, Bioko Island and possibly Gabon. No subspecies are recognized. The two former subspecies, the white-legged duiker Cephalophus crusalbum and the Brooke's duiker Cephalophus brookei, are considered as distinct species since 2011.Colin Peter Groves & Peter Grubb: Ungulate Taxonomy, Johns Hopkins University Press, 2011.

The mangrove black hawk, Buteogallus anthracinus subtilis, is a neotropical bird of prey in the family Accipitridae native to South and Central America. Briefly treated as a distinct species, Buteogallus subtilis, recent evidence strongly suggests it should be considered a subspecies of the common black hawk (Buteogallus anthracinus). Clark, W. S. 2007. Taxonomic status and distribution of Mangrove Black Hawk Buteogallus (anthracinus) subtilis.

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.

It is the largest genus in the tribe with over 129 identified species including E. hyacinthina. Among the distinct species of euglossine bees, the genus Euglossa is known for its bright, metallic skeleton. In neotropical forests, euglossines make up to 25% of the total bee population. The Neotropical Euglossa bees are close relatives of Apini (honey bees) and Bombini (bumblebees).

Under "Listado de Fauna" The word Trimorphodon is a combination of three Greek words, 'tri' - three, 'morph' - shape, and 'odon' - teeth, which refers to the three distinct kinds of teeth that lyre snakes have: recurved anterior teeth; shorter middle teeth, and large grooved fangs at the rear of the jaw. There are two distinct species in the genus Trimorphodon, with seven subspecies.

The confusion was finally clarified in 2019, when several collections from Corsica, Croatia, Cyprus, France and Greece were analysed in an elaborate phylogenetic, biogeographical and ecological treatment by M. Loizides and colleagues. In this study, Leccinellum was phylogenetically validated, while L. lepidum, L. corsicum and L. crocipodium formed well-supported lineages within the genus, and were consequently confirmed as distinct species.

It has been recently shown that P. ovale is actually two genetically distinct species that coexist. These species are Plasmodium ovale curtisi and Plasmodium ovale wallikeri. These two species separated between 1.0 and 3.5 million years ago. ; Knowlesi Plasmodium knowlesi has a natural reservoir in the macaques of Southeast Asia, and was only in 1965 identified as being transmissible to humans.

Humboldt's flying squirrel (Glaucomys oregonensis) is one of three species of the genus Glaucomys, the only flying squirrels found in North America. Using genetic analyses, Arbogast et al. (2017) showed that Humboldt's flying squirrel, previously thought to be conspecific with the northern flying squirrel, was actually a distinct species. These squirrels do not actually fly but glide from tree to tree.

The Christmas Island shrew (Crocidura trichura), also known as the Christmas Island musk-shrew is an extremely rare or possibly extinct shrew from Christmas Island. It was variously placed as subspecies of the Asian gray shrew (Crocidura attenuata) or the Southeast Asian shrew (Crocidura fuliginosa), but morphological differences and the large distance between the species indicate that it is an entirely distinct species.

Till a recent study, this species was mistaken to be Beddome's cat snake and was extralimitally reported from dry forests of eastern peninsular India. New research on both museum collections and fieldwork led to its discovery as a new, distinct species. Holotype: BMNH 1911.9.8.4, female, from Brahmapur Ganjam district, in Odisha state, India, presented by Major Frank Wall in 1911.

The Vietnamese orangutan (Pongo hooijeri) is an extinct species of orangutan from the Pleistocene of Vietnam. It was named in honor of paleontologist Dirk Albert Hooijer. Fossils of the ape were found in the Tham Hai Cave. It is unclear whether Pongo hooijeri is truly a distinct species or merely a Vietnamese population of one of the extant orangutan species.

The Christmas Island flying fox or Christmas Island fruit bat, as the name suggests, is a flying fox endemic to Christmas Island. It is unclear if it should be considered a distinct species (Pteropus natalis), or a subspecies of the black-eared flying fox (P. melanotus natalis). It may descend from a population of island flying foxes from Pulau Panjang near Java.

The serrations probably helped anchor an even larger keratin extension. Specimens of Darwinopterus have been divided into three distinct species, based largely on the size and shape of their teeth. The first, D. modularis, was named by Lü Junchang and colleagues in 2010. D. modularis had an especially elongated back end to the skull, and widely spaced, "spike-like" teeth.

A recent revision Anderson, C. G., and E. Greenbaum. 2012. Phylogeography of northern populations of the black-tailed rattlesnake (Crotalus molossus Baird and Girard, 1853), with the revalidation of C. ornatus Hallowell, 1854. Herpetol. Monogr. 26: 19–57. showed that eastern populations from Texas and central and eastern New Mexico form a distinct species separate from C. molossus: Crotalus ornatus Hallowell 1854.

It is closely related to, and in some respects intermediate between, Acer cappadocicum, from Asia, and Acer platanoides, from further north in Europe, hence Acer platanoides subsp. lobeli. The suggestion has been made that it could be a natural hybrid between them, but differences from both, notably the strongly glaucous bloom on the young shoots, make treatment as a distinct species more reasonable.

The northern subspecies—V. c. cayennensis from north and V. c. lampronotus from south of the Amazon River—are sometimes separated as a distinct species, Vanellus cayennensis. These two subspecies have a browner head—particularly the northernmost birds—and the white face band (broad in the northern and narrow in the southern one) does not reach to the center of the crown.

An upper pitcher of N. × pyriformis Nepenthes inermis is known to hybridise with N. talangensis on the upper slopes of Mount Talang, where the two species grow sympatrically. N. talangensis was only described as a distinct species in 1994.Nerz, J. & A. Wistuba 1994. Five new taxa of Nepenthes (Nepenthaceae) from North and West Sumatra . Carnivorous Plant Newsletter 23(4): 101–114.

Newer research, based on both morphological and mitochondrial DNA data, has however concluded that the East Siberian cod is not a distinct species from the Arctic cod, but the genus Arctogadus comprises just a single species i.e. the Arctic cod Arctogadus glacialis.Jordan AD, Møller PR, Nielsen JG (2003) Revision of the Arctic cod genus Arctogadus. Journal of Fish Biology 62:1339–1352.

Etheridge, E.C.; C. E. Adams; C. W. Bean; N. C. Durie; A. R. D. Gowans; C. Harrod; A. A. Lyle; P. S. Maitland; and I. J. Winfield (2012). Are phenotypic traits useful for differentiating among a priori Coregonus taxa? Journal of Fish Biology 80: 387–407. The FishBase and IUCN continue to recognize the Scottish powan as a distinct species, Coregonus clupeoides.

Taurine cattle (Bos taurus taurus), also called European cattle, are a subspecies of domesticated cattle originating in the Near East. Both taurine cattle and indicine cattle (zebus) are descended from the aurochs. Taurine cattle were originally considered a distinct species, but are now typically grouped with zebus and aurochs into one species, Bos taurus. Most modern breeds of cattle are taurine cattle.

Amanita persicina, commonly known as the peach-colored fly agaric, is a basidiomycete fungus of the genus Amanita. This fungi was previously believed to be an Amanita muscaria variant, but research has recently shown that Amanita persicina is not a fly agaric, but its own distinct species. Amanita persicina is distinguished by its peach-colored center and its eastern North American distribution.

Haasiella is a fungal genus in the family Hygrophoraceae. It is a monotypic genus that contains only the species Haasiella splendidissima. Haasiella venustissima, formerly considered to be a distinct species based on its one and two-spored basidia, was found by a DNA study to be synonymous with H. splendidissima. H. splendidissima is only known from Europe and is saprotrophic on wood.

Kunzea 'Badja Carpet' is a cultivar of Kunzea badjaensis. It is a low-growing shrub of the family Myrtaceae found in the southeastern tablelands of New South Wales, Australia. It is similar to Kunzea capitata, but it has a lower growth form and white rather than pink flowers. Because of these differences it has been described as a distinct species.

The number of subspecies of S. subspinipes is unclear and varies between authors. Taxonomic characters have incorporated plastic traits such as colour and sulcus structure and the number and position of spines, producing indistinguishable and intergrading subspecies. A 2012 review found that one former subspecies, S. subspinipes cingulatoides is in fact a distinct species, and that S. subspinipes has no valid subspecies.

It was long considered a subspecies of the square-tailed drongo (Dicrurus ludwigii) but a 2018 study of genetic divergences indicated that both were distinct species. It can be physically distinguished from D. ludwigii by the lack of white tips on the axillaries as well as having a dull purplish-blue iridescence rather than the greenish blue-black iridescence of D. ludwigii.

The black-throated laughingthrush (Pterorhinus chinensis) is a species of bird in the family Leiothrichidae. It is found in Cambodia, China, Laos, Myanmar, Thailand, and Vietnam. It occurs as an introduced species in Hong Kong. Based on a combination of strong morphological and genetic evidence, the subspecies on Hainan Island is treated as a distinct species by some authors, Swinhoe's laughingthrush (Garrulax monachus).

Polioviruses were formerly classified as a distinct species belonging to the genus Enterovirus in the family Picornaviridae. In 2008, the Poliovirus species was eliminated and the three serotypes were assigned to the species Human enterovirus C (later renamed Enterovirus C), in the genus Enterovirus in the family Picornaviridae. The type species of the genus Enterovirus was changed from Poliovirus to (Human) Enterovirus C.

Colaspis costipennis is a species of leaf beetle from North America. It is mostly found in coastal states; in the United States, its range extends from Louisiana and Georgia north to New Hampshire and Pennsylvania, and in Canada, it is reported from Ontario. It was originally described as a variety of Colaspis brunnea, but it is now recognised as a distinct species.

Constantine John Phipps was the first to describe the polar bear as a distinct species in 1774. He chose the scientific name Ursus maritimus, the Latin for 'maritime bear', due to the animal's native habitat. The Inuit refer to the animal as nanook (transliterated as nanuq in the Inupiat language). The Yupik also refer to the bear as nanuuk in Siberian Yupik.

Morchella vulgaris is a widespread fungus of the family Morchellaceae (Ascomycota). It was originally described in 1801 as a form of the common yellow morel (Morchella esculenta) by mycologist Christiaan Hendrik Persoon, but was later recombined as a distinct species by Samuel Gray.Gray SF. (1821). A Natural Arrangement of British Plants, according to their relations to each other Vol. 1. p. 662.

A new iteration of the Chitauri (inspired by their portrayal in The Avengers film) first appeared in the mainstream Earth-616 continuity and unlike their Earth-1610 counterpart, they are a distinct species from the Skrulls. Most of them are simple-minded dogged creatures, similar to insects, to the point of following a queen.Captain America: Steve Rogers #8. Marvel Comics.

The name oligoclase was given by August Breithaupt in 1826 from the , little, and , to break, because the mineral was thought to have a less perfect cleavage than albite. It had previously been recognized as a distinct species by J. J. Berzelius in 1824, and was named by him soda-spodumene (Natron-spodumen), because of its resemblance in appearance to spodumene.

It is separated from the New Guinea crocodile by the New Guinea Highlands, a mountain range that runs along the centre of the island. DNA analysis has revealed these to be genetically distinct species, and there are some differences in their morphology and behavior. There are estimated to be between 50,000 and 100,000 New Guinea and Hall's New Guinea crocodiles in the wild.

The rest were acrocentric. The X chromosome is a large acrocentric, while the Y chromosome is a minute one. This species of wildebeest seems to have evolved around 2.5 million years ago. The black wildebeest is believed to have diverged from the blue wildebeest to become a distinct species around 1 million years ago, in the Middle to Late Pleistocene.

In 1949 it was classified by Raymond as: Carex capitata f. arctogena, and in 1958 Eric Hultén proposed C. arctogena be classified as a variety of C. capitata. None of these were widely accepted and today we have genetic evidence that these are two distinct species. Genetic analyses has verified that C. arctogena and C. capitata share a common origin.

Five subspecies have been recognized in the past, but recent genetic analysis shows that A. contortrix and two of the subspecies are monotypic, while Agkistrodon laticinctus (formerly Agkistrodon contortrix laticinctus) and the fifth subspecies are a single distinct species (see subspecies table below). It is a common species in many areas within its range, which may lead to accidental encounters with humans.

Chaetodon citrinellus is a species of butterflyfish (family Chaetodontidae). It is commonly known as the speckled butterflyfish or citron butterflyfish. It is found in the Indo-Pacific: the Red Sea, East Africa to the Hawaiian, Marquesan and Tuamotu islands, north to southern Japan and south to Australia. It is a distinct species, most closely related to the fourspot butterflyfish (C. quadrimaculatus).

The status of this rarely seen bird is not known, primarily because it is not clear whether it is in fact a distinct species, or a natural hybrid between the black-headed bulbul and the grey-bellied bulbul or other closely related bulbul. Alternate names for the blue-wattled bulbul include the Malayasian wattled bulbul, Nieuwenhuis's bulbul and wattled bulbul.

Chapter VII raises the issue of whether different races have similar diseases (p162 et seq) and ends with a list of reasons for placing man in one distinct species. The reasons are mostly anatomical with some behavioural, such as speech. They remain valid today. Next there is a lengthy discussion of variation in man, and of the differences between races.

In 2000, DNA testing confirmed the theory that there are three species of right whale, as the North Pacific right whale (Eubalaena japonica) is a distinct species from the North Atlantic right whale (E.glacialis). Strictly speaking, this is not a newly discovered species, but simply an alternative taxonomic treatment, as japonica already was widely recognized, but "only" as a subspecies.

Until its confirmation as a distinct species, it was frequently misidentified as the eastern North American species L. sulphureus, which grows on hardwoods. L. conifericola is generally considered edible, but some people have reported having gastrointestinal upset after consuming the fungus. Young specimens with soft flesh, or the fresh margins of older fruit bodies are best for eating, and thorough cooking is recommended.

In May 2020, the IOC world bird list the split of western and eastern subalpine warbler as two distinct species. This is a bird of dry open country, often on hill slopes, with bushes for nesting. The nest is built in low shrub or gorse, and 3–5 eggs are laid. Like most "warblers", it is insectivorous, but will also take berries.

A 2007 phylogenetic study confirmed the new taxonomic system. Blacks corals are classified in the order Antipatharia with 7 families, 44 genera, and 280 distinct species. The families are Antipathidae, Aphanipathidae, Cladopathidae, Leiopathidae, Myriopathidae, Schizopathidae, and Stylopathidae. Black corals can be distinguished from other corals by their black, flexible skeletons and near- total lack of any kind of protection from sediment.

Pseudoeurycea nigromaculata, commonly known as the black-spotted salamander or black-spotted false brook salamander is a species of salamander in the family Plethodontidae. It is endemic to Veracruz, Mexico, and known from Cerro Chicahuaxtla ( asl)) in Cuatlalpan (the type locality, near Fortín de las Flores) and from Volcán San Martín at elevations of . These separate populations likely represent distinct species.

The Blue Nile patas monkey (Erythrocebus poliophaeus) is a species of Old World monkey found in Africa along the Blue Nile river valley. It is known from Ethiopia and Sudan, and may be threatened by habitat loss. While first described in 1862, it was synonymized with the patas monkey in 1927. A reclassification in 2018 confirmed its status as a distinct species.

Pseudoeurycea lineola, commonly known as the Veracruz worm salamander or Mexican slender salamander, is a species of salamander in the family Plethodontidae. It is endemic to the Sierra Madre Oriental near Cuautlapan, in the east-central Veracruz, Mexico, at elevations of above sea level. Molecular evidence suggests that it consists of two distinct species. It was the type species of genus Lineatriton.

The Moulton's handfish (Sympterichthys moultoni) is an endangered species of handfish in the genus Sympterichthys. It is endemic to waters off the southeastern coast of Australia and possibly once New Zealand (it is now extinct in New Zealand). It was first described as a distinct species in 2009 by Peter Last and Daniel Gledhill. It lives at a depth of around - .

" Persoonia: 27 (2011): 80-89. Web. There has also been recent molecular evidence to suggest there are several genetically distinct species of Phomopsis that can cause disease on the sunflower hosts. Initial symptoms of P. helianthi infection can be found at the attachment of petiole to the stem on the lower portion of the plant.Herr, L. J. "Diaporthe Stem Canker of Sunflower.

Conventionally, "white witch" refers to two very similar species of Thysania listed in the GBIF database: T. agrippina and T. pomponia (T. zenobia is a third morphologically distinct species). However, a 2016 publication establishes a new species among the subset of moths previously identified as T. agrippina. Thysania winbrechiini is differentiated from T. agrippina by morphological features and DNA evidence.

Groves and Bell (2004) placed all three species in the subgenus Hippotigris. A 2013 phylogenetic study found that the plains zebra is more closely related to Grévy's zebras than mountain zebras. The extinct quagga was originally classified as a distinct species. Later genetic studies have placed it as the same species as the plains zebra, either a subspecies or just the southernmost population.

The taxonomic status of F. compacta is uncertain. The debate whether or not F. compacta is a distinct species of Fonsecaea has persisted for years, essentially since it was discovered. Some authors maintain that F. compacta and F. pedrosoi are separate species given small differences in morphology of conidiophores and conidia. F. compacta and F. pedrosoi are readily distinguishable from each other.

62 Subsequently, the treatment of these species in systematic works became variable. A 1992 paper suggested that alterus and tucumanensis were, at best, very similar to each other, but in 1997, Michael Mares and colleagues listed each of the three as distinct species in a compendium of the mammals of Catamarca, citing differences in habitat and fur coloration.Mares et al.

The DNA analysis confirmed that they are not strongly separated but they must to be separated into distinct species, due largely to genetic differences that occur between other traits in the presence of distinct white markings over the veins in its young leaves as compared to less distinct white markings in young H. pastuchowii leaves, coupled with greater vigour in H. cypria plants.

The Escudo hummingbird (Amazilia tzacatl handleyi) is a hummingbird in the subfamily Trochilinae. It was long considered a doubtfully distinct species, but more recently it is generally treated as a subspecies of the rufous-tailed hummingbird, A. tzacatl. It is endemic to Isla Escudo de Veraguas in Panama. Except for its larger size, it is similar to the rufous-tailed hummingbird.

L. kimberleyensis shares mtDNA haplotypes with the sympatric smallmouth yellowfish (L. aeneus), but is morphologically distinct. This typically indicates either species that have recently diverged, or hybrid introgression, or morphs that are mistakenly considered distinct species. The latter does not seem likely in this case, as the two differ much in size alone, but the actual cause for the genetic similarity remains unstudied.

They are placed in the genus Loxops. Only one of the species in the genus, the Hawaiʻi ʻakepa, is still extant, and is classified as Endangered by the IUCN. Previously considered conspecific, the group was split into distinct species in 2015. Found only in high elevation old growth rainforest, these nonmigratory passerines have rounded heads, black eyes, and black wings and tail.

Matti Hämäläinen studied the type specimens of these taxa and other material preserved in collections of BMNH (London), IRSN (Brussels) and RMNH (Leiden) in 2011. He concluded that there is striking structural and colour differences which indicate that submontana is a distinct species. And its sympatric occurrence with V. apicalis and V. gracilis alone rules out its former subspecies status. So V. a.

Some authors include Juniperus lutchuensis from the Ryukyu Islands in J. taxifolia as a synonym, or variety,Yasushi laboratory: Juniperus taxifolia var. lutchuensis (in Japanese; google translation) while others treat it as a distinct species as it has a distinct DNA profile. Its conservation status, previously given as Data Deficient,Conifer Specialist Group (2000): Juniperus taxifolia is now listed as Vulnerable.

Squalus clarkae, also known as the Genie's dogfish, is a species of shark from the Gulf of Mexico and western Atlantic. It was described in 2018 and named in honor of ichthyologist Eugenie Clark. It was previously believed to be a part of Squalus mitsukurii, but genetic analysis revealed it to be a distinct species. Individuals are usually between and long.

He revived the genus Atylus on the grounds of priority, and correctly made the combination Atylus anemonifolius. However, Kuntze's revisionary program was not accepted by the majority of botanists. Ultimately, the genus Isopogon was nomenclaturally conserved over Atylus by the International Botanical Congress of 1905. Several varieties have been described but have been synonymised with I. anemonifolius or recognised as distinct species.

The giant tortoises (Aldabrachelys) from Aldabra now populate many of the islands of the Seychelles. The Aldabra population is the largest in the world. These unique reptiles can be found even in captive herds. It has been reported that the granitic islands of Seychelles supported distinct species of Seychelles giant tortoises, but the status of the different populations is currently unclear.

The taxonomy of this bird is still somewhat contentious. It is one of five distinct species which were previously considered subspecies of H. himantopus. H. himantopus sensu lato, is made up of one species and 5–7 subspecies, and was sometimes referred to as common stilt. The name black- winged stilt refers to H. himantopus sensu stricto, with two subspecies H.h.

Juniper and Parr, 1998) been regarded as typical of P. lucianii. Joseph (2002) found that this was incorrect, with true P. lucianii being restricted to Brazil and lacking any bright red to the head. The taxonomic position of the population in far north-eastern Peru, labelled as "group 6" by Joseph (2002), therefore remains unclear, it having been speculated that it could be a distinct species, a subspecies of either P. roseifrons or P. lucianii, a hybrid between the P. roseifrons and P. lucianii (which, if found to be true, could indicate that P. lucianii and P. roseifrons are better considered conspecific), or a hybrid between the currently recognized subspecies of P. roseifrons. Arndt (2008) recently argued for treating it as a distinct species, which he described as P. parvifrons, but this has yet to receive widespread recognition (e.g.

In its initial description in 1898, the Tres Marias raccoon was classified as a subspecies of the common raccoon (Procyon lotor) by Clinton Hart Merriam. (This source was used for the whole chapter about classification.) In 1950, Edward Alphonso Goldman identified it as a distinct species, a view that has been upheld by most scientists until recently. In a study of a pair of mounted specimens in 2005, Kristofer M. Helgen and Don E. Wilson came to the conclusion that there are morphological differences between the Tres Marias raccoon and the subspecies Procyon lotor hernandezii of the common raccoon found on the Mexican mainland, but that they are not large enough to justify the classification as distinct species. It is therefore assumed that the Tres Marias raccoon was introduced to the Islas Marías not long ago.

Once considered a single species, theH. insulare complex is now considered to comprise six distinct species based on results of morphological studies, intersterility trials, and genetis. Mating tests have identified four inter-sterility groups: N, T, Y, and Z. The seven species are H. orientale (N-type), H. ecrustosum (T-type), H. insulare sensu typi, H. linzhiense, H. australe, H. amyloideum, H. tibeticum (Z-type).

In parts of Asia, antlers and their velvet are used in traditional medicines. Elk are hunted as a game species. Their meat is leaner and higher in protein than beef or chicken. Elk were long believed to belong to a subspecies of the European red deer (Cervus elaphus), but evidence from many mitochondrial DNA genetic studies beginning in 1998 shows that the two are distinct species.

Model representing a female Homo floresiensis Before the arrival of modern humans, Flores was occupied by Homo floresiensis, a pygmy archaic human. Remains of nine individuals have been found, and the dominant consensus is that these remains do represent a distinct species due to genetic and anatomical differences from modern humans. The most recent evidence shows that Homo floresiensis likely became extinct 50,000 years ago.

Zygaena haematina is a species of moth in the Zygaenidae family. It is found in Iran. Z. haematina approaches Zygaena fraxini, but is much smaller and more narrow-winged, spot 4 is more rounded and there is a red collar, which is absent from fraxini. Rebel considers haematina a distinct species from an examination of the type contained in the Hofmuseum at Vienna: from Persia.

A version of Nyamal became the basis of a pidgin used among workers on pearling luggers in the late 19th century, and was spoken several hundred miles away, as was Ngarluma One Nyamal word has entered English, kaluta, the common term now used to refer to a distinct species of marsupial Dasukaluta Rosamondae, mistakenly classified as an antechinus before it was correctly identified in 1982.

From these measurements, a total length for the shinbone was estimated of about and for the animal as a whole of about . Three diagnostic features were established enabling it to be upheld as a distinct species of dinosaur: the ascending process of the astragalus had a rectangular shape with a straight upper end; the astragalar facet had a vertical ridge; the medial condyle was weakly developed.

It is principally known for containing the largest tropical wooded area in the world. It also contains an incredible range of animal species, most notably the last remaining large felidae and more than 100 other distinct species of mammal. Kaa-Iya del Gran Chaco is linked with Otuquis National Park and newly created Ñembi Guasu conservation area, covering about 60,000 km2 of Gran-Chaco forest.

Parasitology Research, 113(5), 1909-1918. doi:10.1007/s00436-014-3838-4 Sappinia species are not generally susceptible to bacterial infection; but, they have been shown to harbor bacterial endosymbionts. In a recent study, Corsaro et al. (2016), found that all of the Sappinia strains tested harbored distinct species of Flavobacterium and/or Pedobacter, which are not known to be commensals of any other free-living amoebae.

The timberline sparrow (Spizella breweri taverneri) is a taxonomically controversial American sparrow. Usually treated as a subspecies of Brewer's sparrow, it is still considered a distinct species Spizella taverneri by many authorities. While the timberline sparrow recognizably differs in some details, there is little reproductive isolation between the taxa. When it was still considered a species, it was listed as being of least concern by the IUCN.E.g.

Board of Regents Annual Report of the Board of Regents of the Smithsonian Institution. Board of Regents. p. 472 Virchow became one of the leading opponents on the debate over the authenticity of Neanderthal, discovered in 1856, as distinct species and ancestral to modern humans. He himself examined the original fossil in 1872, and presented his observations before the Berliner Gesellschaft für Anthropologie, Ethnologie und Urgeschichte.

Other popular names, usually local and particular to distinct species, liken the flowers' red hues to those of a male chicken's wattles, and/or the flower shape to its leg spurs. Commonly seen Spanish names for any local species are bucaré, frejolillo or porotillo, and in Afrikaans some are called kafferboom (from the species name Erythrina caffra). Mullumurikku is a widespread name in Kerala.

Arumberia is an enigmatic fossil from the Ediacaran period originally described from the Arumbera Sandstone, Northern Territory, Australia but also found in the Urals, East Siberia, England and Wales, Northern France, the Avalon Peninsula and India. Several morphologically distinct species are recognized.Kolesnikov A.V., Grazhdankin D.V. & Maslov A.V. (2012). – Arumberia-type structures in the Upper Vendian of the Urals. – Doklady Earth Sciences, 447 (1), 1233-1239.

The fringe-eared oryx (Oryx beisa callotis) is a subspecies of the East African oryx. It was originally described as a distinct species by Oldfield Thomas in 1892, but was subsequently re-evaluated as a subspecies by Richard Lydekker in 1912. Recently, analysis using the phylogenetic species concept has led some authors to conclude that it should be returned to full species status (Oryx callotis).

Buergeria otai is a species of frogs in the family Rhacophoridae. It is endemic to Taiwan and found in the eastern and southern parts of the island. Buergeria japonica, with whom Buergeria otai was confused before described as a distinct species in 2017, occurs in northwestern Taiwan. The two species have only a narrow contact zone and can be distinguished based on genetic markers, calls, and morphology.

Furca (Latin for "fork") is an extinct genus of Marrellomorph arthropod known from the Sandbian stage (upper Ordovician period) of the Czech Republic. At least three distinct species have been described although they may all be synonyms of the type species, Furca bohemica. A tentative additional species, "Furca mauretanica": was proposed for specimens discovered in Morocco, but this species remains a nomen nudum until formally published.

The Nubian ibex (Capra nubiana) is a desert-dwelling goat species found in mountainous areas of northern and northeast Africa, and the Middle East. Its range is within Algeria, Egypt, Ethiopia, Eritrea, Israel, Jordan, Lebanon, Oman, Saudi Arabia, Sudan, and Yemen. It is historically considered to be a subspecies of the Alpine ibex (C. ibex), but is increasingly considered a specifically distinct species (C. nubiana).

Packwood Lake is home to a genetically distinct species of rainbow trout. This trout has evolved for over a thousand years, separated from other populations of fish. It is known for its excellent taste, large size, and drab creamy coloring. Due to many years of stocking, however, the fish is becoming less and less prominent as its gene pool becomes diluted by stocked fish.

In 1936, Glover Morrill Allen considered this elephant to be a distinct species and called it 'forest elephant'. Later authors considered it to be a subspecies. Morphological and genetic analyses provided evidence for species-level differences between the African bush elephant and the African forest elephant. In 1907, Richard Lydekker proposed six African elephant subspecies based on the different sizes and shapes of their ears.

William Ralph Maxon originally suggested that the type specimen might be a distinct species. However, his suggestion was not taken up until 2004, when John Mickel first described it as Cheilanthes maxoniana, naming it in honor of Maxon. The species is only known from the type specimen, Viereck 76. The development of molecular phylogenetic methods showed that the traditional circumscription of Cheilanthes is polyphyletic.

Christiaan Hendrik Persoon described this species as Agaricus myomyces var. pardinus in 1801, but queried whether it was a distinct species. In his 1838 work Epicrisis systematis mycologici: seu synopsis hymenomycetum, Fries assigned a different fungus again to the binomial name and linked it to Schäffer's 1762 description. French mycologist Lucien Quélet reclassified it as a species in 1873, giving it its current binomial name.

The alder flycatcher is sibling species with the willow flycatcher (E. trailli). The two species were grouped together as one species, the Traill's flycatcher, until 1973, when differences in vocalizations and habitat use lead to their acknowledgement as distinct species, which has since been supported by genetic data.Eisenmann E. 1973. Thirty-second supplement to the American Ornithologists' Union check-list of North American birds. Auk.

Flaveria oppositifolia is a rare Mexican plant species of yellowtops within the sunflower family. It has been found only in northeastern Mexico, from Tamaulipas west to Coahuila, south as far as Hidalgo and Aguascalientes. Some sources report the species to be present in the State of Texas in the United States, but the Texas populations have been recognized as a distinct species, F. brownii.Powell, Albert Michael. 1979.

Pantherophis gloydi, commonly known as the eastern foxsnake or eastern fox snake, is a species of rat snake in the family Colubridae. The species is nonvenomous and is endemic to the eastern Great Lakes region of the United States, as well as adjacent western Ontario in Canada. Pantherophis gloydi is sometimes considered a distinct species and sometimes considered a junior synonym of the species Pantherophis vulpinus.

In 2013, a scientific investigations report by the United States Geological Survey concluded that the Kanab ambersnail is not a genetically distinct species. In January 2020, the Fish and Wildlife Service published a proposed rule removing the Kanab ambersnail from the Federal List of Endangered Species due to "taxonomic error".Proposed Rule: Removing the Kanab Ambersnail From the List of Endangered and Threatened Wildlife, (Jan. 6, 2020).

The species was originally described by American mycologist Charles Horton Peck in 1898. Peck collected the type specimen in Port Jefferson, New York. In 1945, Rolf Singer proposed the variety Boletus auripes var. aureissimus as a new combination of the name Ceriomyces aureissimus described by William Alphonso Murrill in 1938; this taxon is now regarded as a distinct species under the name Boletus aureissimus.

González, L. M., Hiraldo, F., Delibes, M., & Calderón, J. (1989). Zoogeographic support for the Spanish Imperial Eagle as a distinct species. Bulletin of the British Ornithologists' Club, 109, 86-93. It is likely that the eastern imperial eagle is the paraspecies for the Spanish imperial eagle and that the imperial eagle complex reached the Iberian peninsula sometimes between the late Pleistocene era and early Holocene.

It is commonly called "Townsend's dickcissel" (or "Townsend's bunting", "Townsend's finch"Spiza townsendi. Avibase) in reference to the collector whom the scientific name honors. Rather than a distinct species or subspecies, it is (as certainly as this can be said in absence of direct proof) a color variant. Comparing the birds, it is immediately obvious that the yellow lipochrome pigments are entirely absent in "Townsend's dickcissel".

Accessed through: World Register of Marine Species on 2017-11-02. It was incorrectly synonymised with Catriona gymnota from the Western Atlantic but shown to be a distinct species by DNA analysis.Korshunova, T.; Martynov, A.; Picton, B. (2017). Ontogeny as an important part of integrative taxonomy in tergipedid aeolidaceans (Gastropoda: Nudibranchia) with a description of a new genus and species from the Barents Sea. Zootaxa.

Originally, Apoica flavissima was thought to be a variety of Apoica pallens because of similar color and physical characteristics. It wasn't until 1972 that J. Van Der Vecht identified that three distinct species were mistakenly being categorized as one. Today, A. pallens, A. flavissima, and A. gelida are identified by differences in male genitalia. In addition, distinction can be made through slight color differences.

First described by the Swedish mycologist Elias Magnus Fries in 1838, its specific epithet delica is Latin for "weaned". Older names include Christian Hendrik Persoon's Lactarius piperatus var. exsuccus. This species has undergone many taxonomic changes over the years. Russula chloroides is now considered a distinct species because of the very dense lamellae and blue/green zone at the stem apex of some specimens.

Engelmann first named the species Pinus macrophylla, but this name had already been used for another pine, so it had to be renamed; this was done by the French botanist Carrière, who chose to honour Engelmann. Apache pine was sometimes treated as a variety of ponderosa pine in the past (as P. ponderosa var. mayriana), but it is now universally regarded as a distinct species.

These two populations have been classified as mitochondrially distinct, with slightly different breeding periods and a few specific morphological differences, such as wing cord length and tail length. Whether these 2 populations should be considered distinct species has been debated in the scientific community, where some consider N.j.togoto as more of a cryptic lineage and suggest treating it as an invalid taxon until further research is conducted.

The pale-winged midget (Elaphria festivoides) is a species of moth of the family Noctuidae. It is found from coast to coast in southern Canada and the northern United States. Elaphria alapallida was split from Elaphria festivoides by Pogue and Sullivan in 2003. The species is very similar to the Festive Midget E. festivoides, and was not recognized as a distinct species until 2003.

Augochlora pura forages on a variety of flowers, including more inconspicuous flowers like walnut. They have been observed visiting over 40 distinct species. In the laboratory, A. pura even foraged for nectar, pollen, or both at foreign flowers not found near their natural habitat. A female collect pollen from up to ten flowers to provision a single cell, and these are often from different species.

Hyperolius castaneus is a species of frogs in the family Hyperoliidae. It is found in the highlands of western Burundi, Rwanda, and Uganda as well as eastern Democratic Republic of the Congo. Common names of this species include Ahl's reed frog, brown reed frog, and montane reed frog. The status of the putative subspecies Hyperolius castaneus rhodogaster is unclear, and it may actually be a distinct species.

The brucies belong to the subfamily Sigmodontinae and the tribe Akodontini. They are ground-dwellers, and may have a preference for higher altitudes within the rain forest area. Each species is thought to be restricted to a limited area. It is uncertain if they are all distinct species, since many are known from very few specimen, which makes it difficult to know how variable brucies are.

Also found on Aiwa was a single bone of a Porzana rail. Apparently this was yet another distinct species, and if so it is likely to have occurred on Lakeba too. But until more material turns up and is studied, nothing can be said with certainty, particularly in respect of the fact that the white-browed crake (P. cinerea) and the spotless crake (P.

Coregonus trybomi is a freshwater whitefish in the family Salmonidae. It is a spring-spawning type of cisco, which probably has evolved from sympatric vendace (Coregonus albula) independently in a number of Swedish lakes. Only one of those populations survives, and it is therefore considered Critically Endangered by the IUCN Red List. The status of Coregonus trybomi as a distinct species is however questionable.

The brown-necked parrot (Poicephalus fuscicollis), sometimes known in aviculture as the uncape parrot, is a large Poicephalus parrot species endemic to Africa consisting of the savanna-dwelling brown-necked parrot (P. fuscicollis fuscicollis) and grey-headed parrot (P. f. suahelicus) subspecies. It formerly included the Cape parrot (now Poicephalus robustus) as a subspecies before the Cape parrot was re-classified as a distinct species.

Initially, Osborn considered these to be distinct species. The first, he named Dynamosaurus imperiosus ("emperor power lizard"), and the second, Tyrannosaurus rex ("king tyrant lizard"). A year later, Osborn recognized that these two specimens actually came from the same species. Despite the fact that Dynamosaurus had been found first, the name Tyrannosaurus had appeared one page earlier in his original article describing both specimens.

Silverstoneia erasmios is a species of frog in the family Dendrobatidae. It is endemic to Colombia where it is known from the Cordillera Occidental and Cordillera Central in the Antioquia Department. Validity of this species is uncertain; females are indistinguishable from Silverstoneia nubicola but males are unknown. Its higher altitudinal range (to asl) than Silverstoneia nubicola (maximum elevation ) suggests that it might be a distinct species.

Hyperolius rhodesianus is a species of frog in the family Hyperoliidae. H. rhodesianus is part of the Hyperolius viridiflavus superspecies, and it remains debated whether it should be considered a distinct species. It is currently known from extreme western Zimbabwe, but it is quite likely that its range extends into the adjacent Zambia and possibly Botswana. Common name Laurent's reed frog has been proposed for it.

Lactobacillus hilgardii hybridizes easily with Lactobacillus brevis, a bacterium that it is very closely related to. Prior to its classification as a distinct species, L. hilgardii was believed to be L. brevis, and, as a result, the bacterium's ability to hybridize raised doubts about its taxonomy. L. hilgardii grows in wine when it contains 1% autolysed yeast. It also grows in ethanol at 15–18%.

The first specimens of Banksiamyces, known then as Tympanis toomansis, were described in 1887. Specimens continued to be collected occasionally for almost 100 years before becoming examined more critically in the early 1980s, leading to the creation of a new genus to contain what was determined to be three distinct species, B. katerinae, B. macrocarpus, and B. toomansis. A fourth species, B. maccannii, was added in 1984.

Chiasmocleis hudsoni, also known as Hudson's humming frog, is a species of frog in the family Microhylidae. It is found in French Guiana, Suriname, Guyana, Guianan Venezuela, Colombia (Amazonas), and Amazonian Brazil. Chiasmocleis jimi has been included in this species but the most recent genetic analyses support its recognition as a distinct species; both species might include further distinct lineages that warrant recognition as species.

Gran Canaria robin call Adult and juvenile Gran Canaria robins The most distinct birds are those of Gran Canaria (E. r. marionae) and Tenerife (E. r. superbus), which may be considered two distinct species or at least two different subspecies. It is readily distinguished by a white eye-ring, an intensely coloured breast, and a grey line that separates the orange-red from the brown colouration.

When significant evolutionary change occurs, the theory proposes that it is generally restricted to rare and geologically rapid events of branching speciation called cladogenesis. Cladogenesis is the process by which a species splits into two distinct species, rather than one species gradually transforming into another.Gould, Stephen Jay, & Eldredge, Niles (1977). "Punctuated equilibria: the tempo and mode of evolution reconsidered." Paleobiology 3 (2): 115-151. (p.

Argenteohyla siemersi, commonly known as red-spotted Argentina frog, is a species of frog in the family Hylidae. It is monotypic within the genus Argenteohyla. It is found in the catchment of Paraná River in Argentina and Paraguay and in the southern coast of Uruguay. There are two subspecies that might be distinct species: Argenteohyla siemersi siemersi and Argenteohyla siemersi pederseni Williams and Bosso, 1994.

The Festivus. 49: 3–17 – via ResearchGate Variation between various Cerion species within small areas of coastline is significant in comparison to that of other terrestrial gastropod groups- along a 50 kilometer stretch of coastline, seven distinct species and many hybrids are present. Several hybrid-swarm populations were interpreted by Ernst Mayr, representing contact zones between various scattered populations of different species and morphotypes.

The ginbuna can be difficult to distinguish from the common goldfish (Carassius auratus), to which it is closely related. In fact, it has often been treated as a subspecies of goldfish. However, current genetic data suggests that the ginbuna is a distinct species. The ginbuna commonly hybridizes with other species in its genus where they come into contact, as well as with the closely related common carp.

Charles William Beebe: A monograph of the pheasants, New York Zoological Society, 1918-1922, Bd. 3, S. 197 Koklass are boreal adapted species which separate into three distinct species groups. They are one of the few galliforms that regularly fly uphill and are capable of sustained flights of many miles. They are monogamous with a slight tendency toward social polyandry. Both parents rear the chicks.

Are phenotypic traits useful for differentiating among a priori Coregonus taxa? Journal of Fish Biology 80: 387–407. The schelly is listed as a distinct species of whitefish, C. stigmaticus, in FishBase and by the IUCN.

Banksia saxicola, the rock banksia or Grampians banksia, is a species of tree or shrub in the plant genus Banksia. It occurs in Victoria in two distinct populations, one in The Grampians and the other on Wilsons Promontory. Formerly considered to be a form of B. integrifolia, it was described as a distinct species by Alex George in 1981. It is most closely related to Banksia marginata.

The variety Salix fragilis var. decipiens (Hoffm.) K. Koch occurs frequently with the type. It is a smaller shrubby tree, rarely exceeding tall, with completely hairless leaves up to 9 cm long and 2–3 cm broad. According to some botanists, it is a distinct species (treated as Salix decipiens Hoffm.), with, in this view, S. fragilis then being a hybrid between S. decipiens and S. alba.

These snails live in springs. They were long believed to occur only in Andorra, Austria, and parts of France. This disjunct distribution was puzzling, until it was realized that the populations assigned to several other supposedly distinct species actually seem to all belong to one species. In fact, Bythinella reyniesii is probably widespread from western Germany and nearby Belgium through central and eastern France to Andorra.

Morchella casteneae is a species of fungus in the family Morchellaceae (Ascomycota). It was described as new to science in a 2012 study by Clowez and appears to be confined to the Iberian peninsula. A subsequent phylogenetic and nomenclatural study by Richard and colleagues has confirmed M. castaneae as a distinct species and showed the taxa Morchella brunneorosea and Morchella brunneorosea var. sordida to be synonymous.

A closely related plant in North America, sometimes regarded as the variety Rubus idaeus var. strigosus, is more commonly treated as a distinct species, Rubus strigosus (American red raspberry), as is done here. Red-fruited cultivated raspberries, even in North America, are generally Rubus idaeus or horticultural derivatives of hybrids of R. idaeus and R. strigosus; these plants are all addressed in the present article.

The Bornean frogmouth (Batrachostomus mixtus) is bird species in the family Podargidae. Some taxonomists consider it to be a subspecies of the short- tailed frogmouth, but others consider it to be a distinct species. It is found in Indonesia and Malaysia and is endemic to the island of Borneo. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.

ASF 361 is completely distinct from the L. salivarius that it was believed to be. ASF 360 and ASF 361 colonize in high numbers in the esophagus, the stomach, the small intestine, and the cecum due to their aerotolerance. ASF 519 is related to B. distasonis, the species it was mistaken to be. However, like the previous bacteria, it is a distinct species by 16S rRNA evidence.

Tulipa regelii, the plicate tulip or Regel's tulip, is a species of tulip native to southeast Kazakhstan. Rare, growing only in certain dry, rocky areas in the northern foothills of the Tian Shan range, it is a very distinct species with bizarre plicate leaves, usually only one, occasionally two. The species was first formally named by Russian botanist and geographer . It flowers in April.

The Baja pygmy owl (Glaucidium hoskinsii) or cape pygmy owl, is a subspecies of northern pygmy owl restricted to the Mexican state of Baja California Sur. Although some taxonomists, including the International Ornithologists' Union, consider it to be a distinct species, other authorities, including the American Ornithological Society, do not consider it separate, and consider it to be a subspecies of the northern pygmy owl.

Boletus erythrentheron, originally described as a distinct species by Jan Bezděk, was later recombined as the variety B. luridus var. erythrentheron by Albert Pilát and Dermek in 1979, and finally as a subspecies by Jiri Hlavácek in 1995. Carmine Lavorato and Giampaolo Simonini defined the form primulicolor from Sardinia in 1997. Rolf Singer's 1947 variety caucasicus, later recombined as an independent species, Boletus caucasicus Singer ex.

A royal white elephant, as depicted in a Thai painting A white elephant (also albino elephant) is a rare kind of elephant, but not a distinct species. In Hindu puranas, the god Indra has a white elephant. Although often depicted as snow white, their skin is normally a soft reddish-brown, turning a light pink when wet.Men ride albino elephants, Reuters via The Atlantic, 1 March 2012.

Cornufer schmidti is a species of frog in the family Ceratobatrachidae. It was first described as a subspecies of Platymantis papuensis (now Cornufer papuensis). It is the type species of the subgenus Aenigmanura within Cornufer. It is endemic to the Bismarck Archipelago, Papua New Guinea, and is known from the islands of New Britain, New Ireland, and Manus; the Manus population might represent a distinct species.

The trackways here are accessible by a trail with interpretive signage but are rapidly eroding in the lake spillway. Most of the tracks at the three sites have been identified as Charirichnium leonardii.Hunt and Lucas 1998 The Mosquero Creek tracks represent 81 individual ornithopod dinosaurs, of two distinct species, and includes a rare limping track. The trackways also preserve evidence of movement as a group.

The holotype specimen was found in 1911 in the Lower Permian Abo Formation in New Mexico. It consists of the skull and postcranial material including femora, humeri, scapulae, pelvis, a section of the vertebral column, and osteoderms. It was originally described by Case et al. (1913) as a referred specimen of Aspidosaurus (sometimes "Broiliellus") novomexicanus but was subsequently determined to be a distinct species by Carroll (1964).

It was described as a distinct species by Jerdon in 1853 based on specimens collected from Nellore, Andhra Pradesh. Most subsequent authors called the validity of the species in question regarding it as a probable or definite synonym of Hemidactylus triedrus. Uncertainty as to the diagnostic features and geographic extent of H. subtriedrus relative to H. triedrus require a thorough taxonomic revision of both the species.

Gompper et al., 2006 The Cozumel coati, sometimes recognized as a separate species, Nasua nelsoni, belongs to the same species as the mainland white-nosed coati (Nasua narica),Wozencraft, 2005, p. 626 but the raccoon is still classified as a distinct species, the Cozumel raccoon (Procyon pygmaeus).Wozencraft, 2005 The Cozumel fox, related to the mainland gray fox (Urocyon cinereoargenteus), has yet to receive a scientific name.

When first described in 1921, Einar Lönnberg classified Anoura aequatoris as a subspecies of Anoura caudifer. In 2006, Mantilla-Meluk and Baker argued that there were enough differences between the two to elevate Anoura aequatoris to the level of distinct species. This conclusion, however, has been challenged. Some believe that it is not distinct enough to warrant separation from A. caudifera, and that further analysis is needed.

M. chlorophos is classified in the section Exornatae of the genus Mycena. Other luminescent species in this section are M. discobasis and M. marginata. Some authors have considered M. illuminans to be synonymous with M. chlorophos due to their morphological similarity, but molecular analysis has shown that they are distinct species. In Japan, the mushroom is known as yakoh-take, or "night-light mushroom".

Nesoryzomys indefessus narboroughi is a subspecies of Nesoryzomys indefessus, a rodent in the genus Nesoryzomys, from Fernandina Island in the Galápagos Islands. The only other subspecies occurred on Indefatigable Island, but is now extinct.Musser and Carleton, 2005 Some consider the two to be distinct species, in which case the Fernandina form would be Nesoryzomys narboroughi. Another, larger, Nesoryzomys is also found on Fernandina—Nesoryzomys fernandinae.

Although discovered in 1982 by Ray Leggett,Unmack PJ (2016) Fishes of Sahul, 30(3): 1025–1032 (September 2016) the species was never formally described as its taxonomy was unclear.Unmack PJ and Hammer MP (2015) Fishes of Sahul, 29(4): 933–936 (December 2015) However, genetic analysis supports the Running River rainbowfish as a distinct species, rather than a colour variety of the eastern rainbowfish.

Some authorsE.g. Hinkelmann (1999) consider the sooty barbthroat to be a melanistic variant of the pale-tailed barbthroat (T. leucurus). As T. niger was described first, this scientific name is the valid name for both when they are considered conspecific. On the other hand, the SACC for example considers T. niger and T. leucurus distinct species, because of insufficient published evidence for their being conspecific.

Agathis spathulata, the New Guinea kauri, is a species of Agathis native to the highlands of eastern Papua New Guinea, occurring at altitudes of 900–1980 m. Although long known, it has only relatively recently (1980) been distinguished from Agathis robusta, being described first as a subspecies of it, Agathis robusta subsp. nesophila Whitm., and subsequently separated as a distinct species Agathis spathulata in 1988.

Fargesia Rufa, sometimes also sold under the name Gansu 95-1 or incorrectly as Fargesia rufa (which is a distinct species), is a commonly cultivated form of bamboo. Its origin is somewhat mysterious, but morphological evidence seems to suggest that it is a cultivar of Fargesia dracocephala. It was introduced into the western horticultural trade in 1995 from the Gansu Province in northwest China.

Arundinaria appalachiana was first distinguished under the name Arundinaria tecta var. decidua, which was applied by C.D. Beadle in 1914 upon noticing the deciduous leaves. Beadle himself and many botanists to follow noted that hill cane may be a distinct species. During the second half of the twentieth century it became quite clear that hill cane could not be properly treated within A. tecta or A. gigantea.

Dutch ichthyologist Pieter Bleeker described the sicklefin weasel shark in 1852. He gave it the specific epithet microstoma, from the Greek mikros ("small") and stoma ("mouth"), and placed it in a new genus, Hemigaleus. His account was based on two females from Jakarta, Indonesia, measuring long. This species was once thought to occur off Australia, but that population is now recognised as a distinct species, H. australiensis.

Adult female near Bwindi (Uganda) Jameson's antpecker (Parmoptila jamesoni) is a songbird species found in central Africa. Like all antpeckers, it is tentatively placed in the estrildid finch family (Estrildidae). It has traditionally been included as a subspecies of P. rubrifrons (red-fronted antpecker) and the common name Jameson's antpecker was sometimes used for both taxa. But today, they are often considered distinct species.

Taxodium ascendens, also known as pond cypress, is a deciduous conifer of the genus Taxodium, native to North America. Many botanists treat it as a variety of bald cypress, Taxodium distichum (as T. distichum var. imbricatum) rather than as a distinct species, but it differs in ecology, occurring mainly in still blackwater rivers, ponds and swamps without silt-rich flood deposits. It predominates in cypress dome habitats.

Trachelomonas is a genus of swimming, free-living euglenoids characterized by the presence of a shell-like covering called a lorica. Details of lorica structure determine the classification of distinct species in the genus. The lorica can exist in spherical, elliptical, cylindrical, and pyriform (pear- shaped) forms. The lorica surface can be smooth, punctuate or striate and range from hyaline, to yellow, or brown.

The mangrove monitor, mangrove goanna, or Western Pacific monitor lizard (Varanus indicus) is a member of the monitor lizard family with a large distribution from northern Australia and New Guinea to the Moluccas and Solomon Islands. Populations from the Marshall Islands, Caroline Islands, and Mariana Islands formerly classified in V. indicus are now considered to comprised two distinct species. It grows to lengths of .

The seminal taxon Morchella elata, whose true identity still remains unresolved, was described by Elias Fries in 1822, from a fir forest in Sweden. Other classical, early-proposed names include Morchella deliciosa, also described by Fries in 1822, Morchella semilibera, the half-free morel, originally described by de Candolle and sanctioned by Fries in 1822, Morchella vulgaris, which was recombined by Samuel Gray as a distinct species in 1821 following a forma of M. esculenta previously proposed by Persoon, and Morchella angusticeps, a large-spored species described by American mycologist Charles Peck in 1887. Morchella purpurascens, the purple morel, was first described by Boudier as a variety of M. elata in 1897 based on an 1834 plate by Krombholz, and was recombined as a distinct species in 1985 by Emile Jacquetant. Morchella eximia, a globally-occurring fire-associated species was also described by Boudier in 1910.

But the different appearance and allopatric ranges argue in favor of recognizing the two as distinct species. According to "Birds of Northern South America" by Robin Restall the back is barred and the belly and breast are white, but that appears to be in error based on photos of the birds in Colombia. Its natural habitats are subtropical or tropical moist lowland forests and heavily degraded former forest.

The northern harrier (Circus hudsonius) is a bird of prey. It breeds throughout the northern parts of the northern hemisphere in Canada and the northernmost USA. While many taxonomic authorities split the northern harrier and the hen harrier into distinct species, others consider them conspecific. It migrates to more southerly areas in winter with breeding birds in more northerly areas moving to the southernmost USA, Mexico, and Central America.

It was subsequently however noted that tephronotus and schach co-occurred in the Kumaon region and so the two were confirmed as distinct species. Molecular distances also indicate that they are distant enough. The erythronotus group have a grey head which continues into the back with a gradual suffusion of rufous. The westernmost population from Transcaspia named by Sergei Buturlin as jaxartensis and said to be larger, is not considered valid.

The closely related Taxodium ascendens (pond cypress) is treated by some botanists as a distinct species, while others classify it as merely a variety of bald cypress, as Taxodium distichum var. imbricatum (Nutt.) Croom. It differs in shorter leaves borne on erect shoots, and in ecology, being largely confined to low-nutrient blackwater habitats. A few authors also treat Taxodium mucronatum as a variety of bald cypress, as T. distichum var.

The scientific name Paradoxurus aureus was proposed by Frédéric Cuvier in 1822. It used to be considered a synonym of the golden palm civet P. zeylonensis. It was proposed to be reclassified as a distinct species by Colin Groves in 2009 based on coat colour and skull measurements of zoological specimens. Genetic analysis indicates that specimens of P. montanus, P. aureus and P. stenocephalus share the same haplotype.

The scarlet-breasted fruiteater (Pipreola frontalis) is a species of bird in the family Cotingidae. It is found in Bolivia, Ecuador, and Peru where its natural habitat is subtropical and tropical moist montane forests. Two subspecies are recognised though some researchers consider these should be regarded as distinct species. It is a plump green bird with a black head, the males having red throats and the females yellow.

New Zealand bittercress was described by Hooker as “a small and very distinct species of Cardamine, wiry and fragile in every part’’. The plant has a low and spreading growth habit with unbranched stems which creep along the ground. It produces daughter plants through rooting at the nodes. The basal, compound leaves have three to five leaflets, with the terminal leaflet being up to twice as large as the lateral ones.

The male (left) is smaller and lighter colored than the female. The species has a particularly marked sexual dimorphism, which originally led naturalists to classify the male and female as distinct species. The male measures 5-6 cm, is light brown and clearly differs from the female. The female is black and measures between 8-9 cm on average, although specimens exceeding 12 cm in length have also been found.

Davidia involucrata is the only member of its genus, but there are two varieties differing slightly in their leaves, D. involucrata var. involucrata, which has the leaves thinly pubescent (short-haired) on the underside, and D. involucrata var. vilmoriniana, with glabrous (hairless) leaves. Some botanists treat them as distinct species, with good reason, as the two taxa have differing chromosome numbers so are unable to produce fertile hybrid offspring.

In 2010, the species was confirmed as separate from the olive thrush (Turdus olivaceus) due to genetic differences. Their ranges do not overlap. The southern and northern populations may be distinct species. The Abyssinian thrush is found in Eritrea and other parts of the Horn of Africa, as well as an area to the southeast extending from the African Great Lakes region to north eastern Zambia and Malawi.

The Nooksack dace is a small cyprinid fish occurring in streams in southern British Columbia and western Washington state. It has not yet been formally described taxonomically. It is considered a genetically distinct subspecies of longnose dace (Rhinichthys cataractae), but may be a distinct species. In Canada, the distribution of the Nooksack dace is limited to four streams: three in the Nooksack basin, and one in the Fraser basin.

The Puerto Rican spindalis was originally classified as Spindalis zena portoricensis, making it a subspecies of the western spindalis (Spindalis zena). In 1997, an article was published which presented an extensive analysis of the genus Spindalis. The report concluded, based on differences in weight, color, pattern, distribution, and voice, that a split of S. zena was necessary. Four distinct species were identified—Spindalis dominicensis, Spindalis nigricephala, Spindalis portoricensis and Spindalis zena.

The scientific name Felis catus was proposed by Carl Linnaeus in 1758 for a domestic cat. Felis catus domesticus was proposed by Johann Christian Polycarp Erxleben in 1777. Felis daemon proposed by Konstantin Alekseevich Satunin in 1904 was a black cat from the Transcaucasus, later identified as a domestic cat. In 2003, the International Commission on Zoological Nomenclature ruled that the domestic cat is a distinct species, namely Felis catus.

Utricularia naviculata is a very small, annual suspended aquatic carnivorous plant that belongs to the genus Utricularia. It is a very distinct species with relatively large bracts and unique trap-bearing shoots ("leaves"). U. naviculata is endemic to South America and is known only from the type location in Venezuela and a single collection in Brazil. It is found at low altitudes in slow-flowing or still waters.

The species was first described by Austrian botanist Karl Von Krapf in 1782 as Agaricus fuliginosus. Elias Magnus Fries sanctioned this name in his 1821 Systema mycologicum, and later (1838) transferred it to the genus Lactarius in his Epicrisis Systematis Mycologici. Other synonyms include Paul Kummer's 1871 Galorrheus fuliginosus and Otto Kuntze's 1891 Lactifluus fuliginosus. Paul Konrad and André Maublanc's subspecies picinus is now known as the distinct species L. picinius.

Hedera maderensis, the Madeiran ivy, is a species of ivy (genus Hedera) which is native to the Atlantic coast in Madeira island. It is a plant of botanical family Araliaceae, species endemic to the island of Madeira with the name: Hedera maderensis (K. Koch ex A. Rutherf). Formerly a subspecies named Hedera maderensis iberica, one iberian subspecies in west Iberian peninsula was subsequently classified as a distinct species.

Tawny owl (Strix aluco) and Hume's tawny owl (Strix butleri) are distinct species: evidence from nucleotide sequences of the cytochrome b gene. Zeitschrift für Naturforschung C, 49(3-4), 230-234.Kirwan, G. M., Schweizer, M., & Copete, J. L. (2015). Multiple lines of evidence confirm that Hume's Owl Strix butleri (AO Hume, 1878) is two species, with description of an unnamed species (Aves: Non-Passeriformes: Strigidae). Zootaxa, 3904(1), 28-50.

Until recently only two species were recognised, G. religiosa and G. ptilogenys. Previously, all Gracula were considered to belong to a very variable species commonly called the hill myna. Three additional subspecies of G. religiosa are increasingly being considered as distinct species. Formerly, the Sri Lanka hill myna was considered to be a subspecies of the common hill myna, but today all major authorities recognise them as separate.

Acis species were at one time placed in the genus Leucojum. What is now considered to be Acis ionica was initially confused with Leucojum valentinum (Acis valentina), a species found in Spain near Valencia. Doubts over this identification began around 1990, and both morphological and molecular evidence began to suggest that it was a distinct species. It was first described as a separate species in 2004 as Leucojum ionicum.

Hyla annectans is a species of tree frog in the family Hylidae. It is found in Asia south of the Himalayas in northeast India (Assam, Nagaland, Manipur, and Meghalaya), northern Myanmar, and northern montane Vietnam and southwestern and central China (Yunnan, Guizhou, Sichuan, Hunan). There are isolated records in northwestern Thailand and adjacent Myanmar. There is uncertainty whether Hyla gongshanensis from China should be recognized as a distinct species.

Parnassius cardinal, the cardinal Apollo, is a high-altitude butterfly which is found in north Afghanistan and Tajikistan. It is a member of the snow Apollo genus (Parnassius) of the swallowtail family (Papilionidae). The species was first described by Grigory Grum-Grshimailo in 1887. P. cardinal which was described as a species was for many years thought to be a subspecies of Parnassius delphius but it is a distinct species.

A new species of Eclipta (Compositae: Heliantheae) and its allies in eastern Asia. Thai Forest Bulletin (Botany) 35 108-18; includes photo of type specimen at Kyoto University National Science Museum herbarium in Japan, collected in Thailand Eclipta angustata was for years regarded as part of the species E. prostrata before being recognized as a distinct species in 2007. It differs in having sessile leaves, subovate achenes, and conspicuous tubercules.

The pronotum is laterally yellow. The anterior side of the synthorax has broad longitudinal humeral stripe; the lateral side of synthorax has yellow metepisternum and metepimeron. The wings are transparent or with dark cross-bands of different widths (specimens with different wing types were originally considered to represent distinct species, but are now regarded as intraspecific variation). The pterostigma is yellowish-brown, darkening with age and ultimately becoming totally black.

In the last three decades of the 20th century, Canna species have been categorised by two different taxonomists, Paulus Johannes Maria Maas from the Netherlands and Nobuyuki Tanaka from Japan. In this case both agree that C. flaccida is a distinct species, and the DNA work by Prince and Kress at the Smithsonian Institution confirms its uniqueness.Tanaka, N. 2001. Taxonomic revision of the family Cannaceae in the New World and Asia.

Currently, four subspecies of ringneck are recognised, all of which have been described as distinct species in the past: (As of 1993, the twenty-eight and Cloncurry parrot were treated as subspecies of the Port Lincoln parrot and the mallee ringneck, respectively). Several other subspecies have been described, but are considered synonyms with one of the above subspecies. B. z. occidentalis has been synonymised with B. z. zonarius.

With the exception of D. calkinsi, which was tentatively excluded from Daeodon, the other previously recognized species of Daeodon were also synonymized to D. shoshonensis. That same year, an obscure entelodont, Boochoerus humerosum, was also synonymized to Daeodon by Foss and Fremd (1998) and, albeit its status as a distinct species was retained, they note that the differences could still be attributed to individual or population variation or sexual dimorphism.

Despeciation is the loss of a unique species of animal due to its combining with another previously distinct species. It is the opposite of speciation and is much more rare. It is similar to extinction in that there is a loss of a unique species but without the associated loss of a biological lineage. Despeciation has been noted in species of butterflies, sunflowers, mosquitoes, fish, wolves, and even humans.

Felis guttula was the scientific name used in 1872 by Hensel when he described a tiger cat from the jungles of the Rio Grande do Sul in southern Brazil. It was long considered to be a subspecies of the oncilla Leopardus tigrinus. It was recognized as a distinct species in 2013. It is closely related to Geoffroy's cat L. geoffroyi, with which it reportedly interbreeds in southern Brazil.

Cortinarius pseudocupreorufus is a species of fungus in the large mushroom genus Cortinarius (subgenus Phlegmacium). It was originally described as new to science in 1944 by American mycologist Alexander H. Smith as a variety of Cortinarius orichalceus. Molecular and morphological data suggests that it is sufficiently distinct to warrant recognition as a distinct species, and it was renamed in 2014. The specific epithet pseudocupreorufus refers to its resemblance to Cortinarius cupreorufus.

Lithograph from Illustrations of Indian Zoology (1832) Otis macqueenii was proposed by John Edward Gray in 1834 for a bustard from India drawn by Thomas Hardwicke. It was long regarded a subspecies of the African houbara bustard Chlamydotis undulata. It was classified as a distinct species in 2003. The genus name Chlamydotis is from Ancient Greek khlamus, a horseman's cloak with weights sewn into the corners, and otis, bustard.

In general, the smaller forms occur in coastal mountains, intermediate birds in the Andes, and large, darker, forms breed on the tepuis. The largest of the tepui subspecies, Z. c. perezchincillae, has grey underparts, and the rufous collar extends as a black band of freckles across the breast. This form might be separable as a distinct species, or it might just be a particularly distinct population due to genetic bottleneck effects.

This led to further separation of the distinct species found on Oa. To prevent further violence John Stewart separated the Horde from the rest of the Mosaic world with stone walls.Green Lantern (vol. 3) #14-#15 Concerned about their neighbors Tomar and fellow Xudarians visited the human settlement only to be attacked by overzealous dogmatic humans. When the Xudarians heard of what had taken place they responded in kind.

The Burmese python (Python bivittatus) is one of the largest species of snakes. It is native to a large area of Southeast Asia but is found as an invasive species elsewhere. Until 2009, it was considered a subspecies of Python molurus, but now is recognized as belonging to a distinct species. They are often found near water, marshy type areas, and are sometimes semiaquatic, but can also be found in trees.

He commented that Owen was due to argue for the taxon as a distinct species, but within the genus Iguanodon. This came to pass, and Owen compared at length the teeth of known Iguanodon and those from Fox's specimens. He agreed there were differences, but found them lacking in sufficient distinctiveness to be considered a distinct genus. Regarding Boyd Dawkins' comparison, he acknowledged it, but it did not sway him.

Bombus occidentalis has been speculated to be a subspecies of B. terricola, but most experts now agree that it is its own distinct species. B. terricola is also closely related to B. affinis both phylogenetically and in terms of pheromone signalling. Oftentimes, the B. terricola is so similar to B. affinis that members of B. affinis can invade and dominate entire B. terricola nests without the hosts knowing.

Cuminia is a genus of flowering plant in the family Lamiaceae, first described in 1835. It contains only one known species, Cuminia eriantha. It is endemic to Robinson Crusoe Island, one of the Juan Fernández Islands in the southeast Pacific, off the coast of Chile and politically a part of that country.Kew World Checklist of Selected Plant Families Two varieties are recognized, regarded by some as distinct species: #Cuminia eriantha var.

Sclerophrys langanoensis is a species of toad in the family Bufonidae. It is endemic to northern Rift Valley in Ethiopia, where it has been recorded from Lake Langano (its type locality) and the Awash National Park; the latter population might represent a distinct species. It is likely that this species will also be found in Eritrea and Somalia. Common name Lake Langano toad has been coined for it.

This species is believed to form a superspecies complex with Hirundo striolata. The widely distributed population shows a lot of variation and several have been named as subspecies. Many of these are migratory and overlap in their wintering ranges and field identification of these forms is not reliable. The Sri Lankan breeding population hyperythra is a resident, and are now usually considered a distinct species, the Sri Lanka swallow.

There are minor genetic differences between the morphs and assortative mating occurs, especially in the olive and dark blue (possibly showing the very early stages of separation into distinct species). Some pale individuals have a highly mottled appearance, giving the species the nicknames African koi and Nguni fish. The distinct polymorphism is not seen in the introduced population in Lake Otjikoto. It is very closely related to the banded tilapia (T.

This species has long been confused with Aplysia dactylomela (living in the Atlantic Ocean) because they are morphologically very similar, but genetic studies have shown that those found in the Indo-Pacific are indeed a distinct species Alexander, and Valdés (2013). The ring doesn’t mean a thing: Molecular data suggests a new taxonomy for two Pacific species of sea hares (Mollusca, Opisthobranchia, Aplysiidae). Pacific Science 67: 283–294.

Hyperolius hutsebauti was first described as a subspecies of Hyperolius tuberculatus. It is now recognized as a distinct species within the so-called Hyperolius tuberculatus complex, which includes Hyperolius dintelmanni as the third species. Molecular data suggest that specimens from the eastern part of the range of H. tuberculatus are actually H. hutsebauti, but the actual limits of these species are not known because of the lack of samples.

Microcaecilia taylori is a species of caecilian in the family Siphonopidae. It is known from two widely separated populations, one in southern Suriname and other one in Pará, Brazil, south of the Amazon River. It is not clear whether the gap is real or whether the populations south of the Amazon River represent a distinct species. Microcaecilia taylori was confused with Microcaecilia marvaleewakeae before the latter was described in 2013.

Pristimantis frater is a species of frog in the family Craugastoridae. It is endemic to Colombia and occurs on the eastern slopes of the Cordillera Oriental in the Norte de Santander, Boyacá, Casanare, Cundinamarca, and Meta Departments, as well as in the Serranía de la Macarena (Meta Department). The population in the Serranía de la Macarena might represent a distinct species. Common name Meta robber frog has been coined for it.

Live birds were never described with these colours. Hume proposed that this colouration is an artifact of the taxidermy specimens having aged and being exposed to light, which can turn grey and black to brown. Such a transformation has also turned an aberrant dickcissel (Spiza americana) specimen (sometimes considered a distinct species, "Townsend's dickcissel"), from grey to brown. The two extant Mascarene parrot specimens also differ from each other in colouration.

The Naja haje was first described by Swedish zoologist Carl Linnaeus in 1758. The generic name naja is a Latinisation of the Sanskrit word ' () meaning "cobra". The specific epithet haje is derived from the Arabic word hayya ('حية) which literally means "snake". The snouted cobra (Naja annulifera) and Anchieta's cobra (Naja anchietae) were formerly regarded as subspecies of Naja haje, but have since been shown to be distinct species.

B. telmatiaea was first collected around 1840 by Ludwig Preiss and James Drummond. For many years it was included in B. sphaerocarpa, but by 1980 it was recognised as a distinct species. In recognition of its distinctness from, yet affinity with, B. sphaerocarpa, it was for a time informally referred to as Banksia aff. Sphaerocarpa. It was eventually published by Alex George in his 1981 monograph The genus Banksia L.f.

Penguin / Allen Lane, 2011, S. 60. . Until the late 1980s, the fossil was sometimes referred to as H. sapiens steinheimensis. During this time Neanderthals were also referred to as H. sapiens neanderthalensis. Today, however, many paleoanthropologists assume that Neanderthals and humans emerged independently from a common ancestor, usually this is called H. heidelbergensis, and therefore that two distinct species are to be considered: H. neanderthalensis and H. sapiens.

Las bromelias (Familia Bromeliaceae). Libro Rojo de Plantas de Colombia, volumen 3, Las bromelias, las labiadas y las pasifloras 3: 3: 51–383. This species growth patterns have been open to conjecture as environmentally localised deformations of the more common Vriesea duvaliana as opposed to a distinct species. Found in subtropical or tropical moist montane forests and subtropical or tropical dry shrubland, the study of this species has proven difficult.

In 2006, Hylomyscus and Praomys were confirmed to be distinct genus-group taxa, and H. endorobae was again recognized as a distinct species. Twelve species of Hylomyscus are currently recognized, provisionally arranged in six groups. H. endorobae together with H. denniae and H. vulcanorum comprise the H. denniae group. These three species are quite similar, and they occupy similar habitats that are in relative close proximity to one another.

The native range of Luzula campestris is temperate Europe, extending to North Africa in the south and to the Caucasus in the east. The species has a northern limit at about latitude 63 degrees north in Scandinavia. The closely related Luzula multiflora is native in much of North America, and is a distinct species in the Flora of North America. Some botanists treat it as a variety, Luzula campestris var. multiflora.

African and Indian silverbill are now usually considered distinct species in the Genus Euodice, and the two races of black-throated munia are often also split. The munias are popular in the bird trade and many freed or escaped birds have formed feral colonies in different pockets across the world. The red munia Amandava amandava and green munia Amandava formosa also take the name munia, but are in the genus Amandava.

Psilogramma menephron, the privet hawk moth or large brown hawkmoth, is a member of the family Sphingidae. It was described by Pieter Cramer in 1780. It is usually found in Sri Lanka, India (including the Andaman Islands), Nepal, central and southern China, Thailand, Vietnam, Indonesia and the Philippines. Psilogramma casuarinae from eastern Australia was long treated as a synonym but is now thought to be a distinct species.

The name Kalanchoe thyrsiflora was first validly published for this southern African species by William Henry Harvey in 1862. Based on an error introduced in The Plant List in 2012, the name K. thyrsiflora has been treated by some as a synonym of K. tetraphylla. However, these two names apply to two distinct species. The name K. tetraphylla dates from 1923 and applies to a different species confined to Madagascar.

However, the greatest diversity is in Southern Asia, and similarities between the species have made it difficult to identify distinct species. All members of this genus nest in holes or crevices. Most species are non-migratory and live in their habitat year-round, although the North American red-breasted nuthatch migrates to warmer regions during the winter. A few nuthatch species have restricted ranges and face threats from deforestation.

Bates spent the best part of a year at Ega (now Tefé) in the Upper Amazon (Solimões),Ega/Tefé is on the smaller tributary Tefé, nearly opposite the junction of the large tributary Japurá with the main Amazon. where he reported that turtle was eaten regularly, and insect catches were especially abundant. He found upwards of 7,000 species of insects in the area, including 550 distinct species of butterfly.Bates H.W. 1892.

In 1992 the two variants were recognised within Human herpesvirus 6 on the basis of differing restriction endonuclease cleavages, monoclonal antibody reactions, and growth patterns. In 2012 these two variants were officially recognised as distinct species by the International Committee on Taxonomy of Viruses and named Human betaherpesvirus 6A and Human betaherpesvirus 6B. Despite now being recognised as paraphyletic, the name Human herpesvirus 6 still sees usage in clinical contexts.

Specimens collected from the Macaronesian islands that once thought to be S. coccinea were later determined to be the distinct species S. macaronesica. A 1995 study of the occurrence of British Sarcoscypha (including S. coccinea and S. austriaca) concluded that S. coccinea was becoming very rare in Great Britain. All species of Sarcoscypha, including S. coccinea, are Red-Listed in Europe. In Turkey, it is considered critically endangered.

The scarce swift (Schoutedenapus myoptilus) is a species of swift in the family Apodidae. It has a disjunct range of presence throughout the Afromontane : Cameroon line, Albertine Rift montane forests, Kenya, Tanzania, Malawi and Mozambique. It is the only species in the genus Schoutedenapus. Schouteden's swift (Schoutedenapus schoutedeni) was previously considered a distinct species, but was found to be a darker juvenile or sub-adult scarce swift subspecies chapini.

O. annulifer has a poorly known classification. A number of other species were originally listed as subspecies of it. A 1999 paper suggested that O. annulifer, which at that point was only known from four juvenile specimens, was actually only a juvenile of a different Oligodon species. However, a 2010 paper confirmed the existence of O. annulifer as a distinct species, based on the recent capture of an adult specimen.

There are many similarities between B. ruderatus and B. hortorum, making it difficult to distinguish between the two species. Due to numerous physical similarities, many scientists have suggested reassessing their current status as two distinct species. Both bees are similar sizes, are black with two yellow bands, and the drones have similar genitalia. Although they may be hard to assess at first glance, there are minor physical differences.

Hatiora cylindrica was first described by Nathaniel Britton and Joseph Rose in 1923. It has not always been viewed as a separate species, being included in H. salicornioides as either the form or the variety cylindrica. Molecular phylogenetic studies have confirmed its placement in the genus and in the tribe Rhipsalideae, and also shown that it is closely related to H. salicornioides (which may include some other distinct species).

Pomacea diffusa was originally described as a subspecies of Pomacea bridgesii. Pain (1960) argued that Pomacea bridgesii bridgesii was a larger form with a restricted range, with the smaller Pomacea bridgesii diffusa being the common form throughout the Amazon Basin (Brazil, Peru, Bolivia). Cowie and Thiengo (2003) suggested that the latter might deserve full species status, and the two taxa have been confirmed as distinct species by genetic analyses.

This species is closely similar to Strombus pugilis, the West Indian fighting conch, which has a more southerly range. S. alatus shells have less prominent subsutural spines and slightly more projected outer lips. Some scientists have treated the two as distinct species; others as subspecies. Simone (2005): Comparative Morphological study of representatives of the three families of Stromboidea and the Xenophoroidea (Mollusca, Caenogastropoda), with an assessment of their phylogeny , p. 142.

C. oldhamii is found in Bangladesh, in the terai of mizoram, in Myanmar, Thailand, Vietnam, W Borneo, Sumatra and Java. In addition, Cyclemys oldhami shanensis - sometimes considered a distinct species due to its shell pattern, oft described as looking similar to aged meat - occurs from central Myanmar to Thailand and Cambodia. The type locality was originally given as "Mergui and Siam", and restricted to Mergui by Smith (1931).

Fritillaria gussichiae is a European plant species in the lily family, native to Bulgaria, North Macedonia, Serbia, Albania, and Greece.Tomovic, G., S. Vukojicic, M. Niketic, B. Zlatkovic, V. Strevanovic. 2007. Fritillaria (Liliaceae) in Serbia: distribution, habitats, and some taxonomic notes. Phytologica Balcanica 13 (3):359-370 The plants were once considered part of F. graeca but more recent studies suggest it is a distinct species more closely related to F. pontica.

It is unknown if the species had a sting, due to the preservation of the specimen. The size of the single known worker is larger than any of the studied queens; as Myrmeciinae queens are slightly larger than the other castes in a species, this indicates M. herculeanus is most likely a distinct species. Due to the incomplete nature of the type specimen, the species was placed in Myrmeciites.

The new Aspergilli sections adapted and revised previously established morphological and physiological characteristics of Aspergillli groups and incorporated DNA sequencing analyses to confirm phylogenetic relationships among related Aspergilli. Many species were reassigned to new Aspergilli sections as phylogenetic relationships were confirmed by DNA and genome sequencing experiments. As a result, A. wentii and A. dimorphicus, previously described as synonyms within the A. wentii section, were later confirmed to be distinct species.

Formerly, the Chesapeake logperch was included in Percina caprodes, however, based on morphological and molecular data, Near (2008)Near, T. J. 2008. Rescued from synonymy: a redescription of Percina bimaculata Haldeman and a molecular phylogenetic analysis of logperch darters (Percidae: Etheostomatinae). Bull. Peabody Mus. Nat. Hist. 49:1–18. determined that it warrants recognition as a distinct species with limited global distribution restricted to the Chesapeake Bay watershed.

Both are suspected hybrids, with doubts about the parent species. In 2007, a study conducted on the comparison of king cherry and Yoshino cherry concluded that these trees were categorized as distinct species. However, South Korean media assert that King cherry is the same species as Yoshino cherry. In Korea most of the places for cherry blossom festivals, including Yeouido and Jinhae, are still planted with Japanese Yoshino cherry trees.

Several new subspecies of previously known species were described. Additionally, an alternative taxonomic treatment of the clouded leopard was proposed, in which the taxon diardi, previously considered a subspecies of Neofelis nebulosa, was proposed a separate species, the Sunda clouded leopard (Neofelis diardi). In 2013, the olinguito, living in the Andean cloud forest, was determined to be a distinct species. It had previously been categorized as a small olingo.

As far as known, Felicia nordenstamii was first collected just east of Cape Agulhas by Terence Macleane Salter in 1934. It was recognized as a distinct species by in his 1973 Revision of the genus Felicia (Asteraceae). The species is considered to be part of the section Anhebecarpaea. The species was named in honor of Rune Bertil Nordenstam, a Swedish botanist that collected two specimens of this plant in 1962.

Its main form of reproduction is parthenogenesis. The honeydew it produces is an important source of food for forest honey bees, which produce pine honey. In Greece and Turkey, about 60% of the honey production is derived from it. It is the sole member of the genus Marchalina, though some authors argue that M. caucasica which is currently considered a synonym of M. hellenica may be a distinct species.

Phytophthora hydropathica is an oomycete plant pathogen that is found in aquatic environments such as irrigation and river water. The pathogen was previously classified as P. drechsleri Dre II before being categorized as its own distinct species . P. hydropathica has been primarily found in association with ornamental plant nurseries. The pathogen has been isolated throughout the Southern United States, as well as internationally in Mexico, Italy, and Spain.

It was long known as Ochlodes venatus, but this is a Far Eastern relative. There is still some dispute whether this species should be considered a distinct species or included in O. venatus as a subspecies. Under ICZN rules the specific name, originally proposed as Papilio sylvanus, is invalid as a homonym (of the butterfly now called Anthene sylvanus), but it has been conserved by an ICZN commission decision in 2000.

He went on to argue that these wasps shared a common ancestor that evolved into distinct species based on the species of willow they preferred. Walsh also investigated the phenomena of protective mimicry among insects and argued that it was best explained as an example of natural selection. Darwin was delighted to learn of Walsh's studies and incorporated his findings in later editions of the Origin of Species.

The Art Gallery of Ontario is an art museum and the second most visited museum in Toronto. The Royal Ontario Museum is a museum of world culture and natural history. The Toronto Zoo is home to over 5,000 animals representing over 460 distinct species. The Art Gallery of Ontario contains a large collection of Canadian, European, African and contemporary artwork, and also plays host to exhibits from museums and galleries all over the world.

Eromanga, Queensland A species of Varanus, lizards known as monitors and goannas, that is found in a variety of habitat. Due to the taxonomic uncertainty during the twentieth century the species form and behaviour has included taxa later recognised as distinct species, this includes V. rosenbergi, formerly treated as a subspecies and later elevated, and V. panoptes, described as a new species in 1980 and resolved as a legitimate publication in 2000.

It has many subspecies, some of which may be distinct species. Its summer pelage is dark russet-brown with some light spots on the dorsal side, and ochraceous buff tinged on the belly. In winter it is lighter, with buff to dull brown dorsal pelage. A generalist herbivore, it is found in the mountains of the eastern Tibetan Plateau in China (Gansu, southern Qinghai, Yunnan, and Sichuan), Bhutan, India (Sikkim), and northern Myanmar.

The gray marmot is a palearctic species in the subgenus Marmota. It is most related to the forest-steppe marmot (Marmota kastschenkoi), which was considered a subspecies of the gray marmot until recently recognized a distinct species. The bobak marmot (Marmota bobak) is a sister group to these species and the lineage the gray marmot is thought to evolve from. The gray marmot has two recognized subspecies Marmota baibacina baibacina and Marmota baibacina centralis .

The species was identified in 2012 by researchers from Australian National University, who were conducting a survey of biological diversity in South-western Australia. They identified Ctenotus ora as a distinct species and sister taxon to the threatened Lancelin Island skink (Ctenotus lancelini). The binomial name Ctenotus ora is derived from the genus name Ctenotus meaning "comb-ear", and the Latin ora meaning "coast", "seaside" or "shore"—referring to the species' coastal distribution.

The Visayan miniature babbler (Micromacronus leytensis) is a bird species in the family Cisticolidae. It was for a long time the only member of the genus Micromacronus, but the Mindanao miniature babbler, formerly included in M. leytensis as a subspecies, is now usually held to be a distinct species, M. sordidus. M. leytensis is endemic to the Philippines. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.

The prolific botanist Robert Brown described Grevillea longifolia in 1830 in his Supplementum primum prodromi florae Novae Hollandiae, the specimen having been collected by George Caley somewhere in Port Jackson (Sydney) near the river. Karel Domin relegated it to a subspecies of Grevillea aspleniifolia, but the consensus is for it as a distinct species. Its name is derived from the Latin words longus "long" and folium "leaf", and refers to the long leaves.

Historically, the leopard stingray has been conflated with the reticulate whipray (H. uarnak) or the honeycomb whipray (H. undulata or its synonym, H. fava) in literature; all three are closely similar in size, shape, and coloration. It was described as a distinct species by Peter Last and Mabel Manjaji-Matsumoto in a 2008 Commonwealth Scientific and Industrial Research Organisation CSIRO publication, and given the specific epithet leoparda in reference to its coloration.

The Mindanao pygmy babbler (Dasycrotapha plateni) is a bird species endemic to the Philippines. It had been placed in the family Timaliidae, but it is a close relative of the white-eyes however, and many taxonomists now place it in the family Zosteropidae. The Visayan pygmy babbler was formerly included here as a subspecies, but is usually recognized as a distinct species S. pygmaea today. Together, they were simply called "pygmy babbler".

In Australia, the tree's natural habitat is subtropical forests of New South Wales and Queensland, much of which has been extensively cleared. The Australian population was formerly treated as distinct species under the name Toona australis. The species can grow to around in height and its trunk can reach in girth. The largest recorded T. ciliata tree in Australia grew near Nulla Nulla Creek, west of Kempsey, New South Wales and was felled in 1883.

Salvia blancoana is a prostrate perennial that is native to Spain and northwest Africa. It has narrow blue-green leaves and pale violet-blue flowers. Due to its being highly variable in the wild, and because of similarities to Salvia candelabrum and Salvia lavandulifolia, it has often been confused with those two. Current opinion gives S. blancoana distinct species status, even while some botanists consider it a subspecies of its two close relatives.

The western barn owl (Tyto alba) is usually considered a subspecies group and together with the American barn owl group, the eastern barn owl group, and sometimes the Andaman masked owl make up the barn owl. The cosmopolitan barn owl is recognized by most taxonomic authorities. A few (including the International Ornithologists' Union) separate them into distinct species, as is done here. The western barn owl is native to Eurasia and Africa.

Alcalus sariba, also known as Saribau eastern frog or Saribau dwarf mountain frog, is a species of frog in the subfamily Alcalinae, family Ceratobatrachidae. It is endemic to Sarawak, Malaysian Borneo, where it is known from a small number of locations, including the eponymous Mount Saribau. It has often been included in Alcalus baluensis (=Ingerana baluensis), but is now considered a distinct species. The two species are similar but Alcalus sariba is larger.

Erythrocebus is a genus of Old World monkey. Both species in this genus are found in Africa, and are known as patas monkeys. While formerly considered a monotypic genus, a recent review has argued that some of the northeast African populations are a distinct species, E. poliophaeus (Blue Nile patas monkey), proposing in addition that the subspecies E. p. pyrrhonotus be elevated to full specific status, along with the formerly recognised subspecies E. p.

At least two distinct species of black cardamom occur: Amomum subulatum (also known as Nepal cardamom) and Amomum tsao-ko. The pods of A. subulatum, used primarily in the cuisines of India and certain regional cuisines of Pakistan, are the smaller of the two, while the larger pods of A. tsao-ko (Chinese: wiktionary:草果; pinyin: cǎoguǒ; Vietnamese: thảo quả) are used in Chinese cuisine, particularly that of Sichuan, and Vietnamese cuisine.

The authors also lectotypified a number of names. Nepenthes of Borneo by Charles Clarke was published in the same year as Jebb and Cheek's revision. Unlike the latter work, however, it was primarily an ecological monograph and did not attempt to provide an alternative taxonomic interpretation of the Bornean taxa (with the exception of treating N. borneensis in synonymy with N. boschiana and retaining N. faizaliana as a distinct species).Clarke, C.M. 1997.

Recent studies suggest existence of at least two distinct subspecies: the Persian toad-headed agama (Phrynocephalus persicus persicus De Filippi, 1863) from northern and central Iran, and Horvath's toad-headed agama (Phrynocephalus persicus horvathi Mehely, 1894) from Armenia, Azerbaijan, NW Iran and NE Turkey. The IUCN considers P. persicus and P. horvathi as two distinct species, and classifies the Phrynocephalus persicus as Vulnerable, while Phrynocephalus horvathi is Critically Endangered. This usage has been followed here.

The very broad topic "Life" is also the topic of the chapter. Ridley discusses the history of the gene briefly, including our "last universal common ancestor". ;Chapter 2, Species Ridley discusses the history of human kind as a genetically distinct species. He compares the human genome to chimpanzees, and ancestral primates. He also points out that until the 19th Century, most scholars believed that there were 24 sets of genes, not 23 as known today.

The two taxa can also be distinguished on the basis of their floral morphology; the pedicels of N. villosa have a filiform bract, while those of N. edwardsiana do not. Additionally, N. edwardsiana and N. villosa differ considerably in their altitudinal distributions. The latter species generally occurs at ultrahighland elevations (2300–3240 m), whereas N. edwardsiana is found between 1500 and 2700 m. Where their altitudinal distributions overlap, they are still identifiable as distinct species.

The genus Dicamptodon was formerly thought to contain two species, Cope's giant salamander (D. copei) on the Olympic Peninsula, Washington, and the Pacific giant salamander (D. ensatus) which consisted of three geographic populations, an Idaho isolate, a group in northern California, and a group in Oregon and Washington. In 1989, genetic studies showed D. copei to be a distinct species, and the D. ensatus populations to consist of three species: the Idaho giant salamander (D.

Fossil records of these birds have been dated back to the Eocene period, 60 million years ago. Human history records also date these birds back 5 000 years. The southern bald ibis is part of the genus Geronticus, which includes two distinct species. The southern bald ibis (Geronticus calvus) is restricted primarily to the southern regions of Africa whereas its counterpart, the waldrapp (Geronticus eremita) is found in the northern regions of the continent.

The Actinomycetales are an order of Actinobacteria. A member of the order is often called an actinomycete. The actinomycetes are diverse and contain a variety of subdivisions, as well as yet-unclassified isolates, mainly because some genera are difficult to classify because of a highly niche-dependent phenotype. For example, Nocardia contains several phenotypes first believed to be distinct species before their differences were shown to be entirely dependent on their growth conditions.

CO;2 HTML abstract was actually conducted on the 'warm season' population from the Azores, which was later recognized as a distinct species (see below). The band-rumped storm petrel is strictly nocturnal at its breeding sites to avoid predation by gulls and diurnal raptors such as peregrines, and will even avoid coming to land on clear moonlit nights. Like most petrels, its walking ability is limited to a short shuffle from/to the burrow.

Magnolia stellata, sometimes called the star magnolia, is a slow-growing shrub or small tree native to Japan. It bears large, showy white or pink flowers in early spring, before its leaves open. This species is closely related to the Kobushi magnolia (Magnolia kobus), and is treated by many botanists as a variety or even a cultivar of that. However, Magnolia stellata was accepted as a distinct species in the 1998 monograph by Hunt.

Cockerell and his wife traveled to the United Kingdom in 1921. While there, they visited the Royal Botanic Garden Edinburgh where, according to himself in 1937, Isaac Bayley Balfour proved that the plant Primula ellisiae was a distinct species from P. rusbyi. He had named this taxon in honor of its discoverer, one of his students, Charlotte Cortlandt Ellis. However, at present this taxon is regarded as a synonym of P. rusbyi.

Introgression can also move genes between otherwise distinct species and sometimes even genera, complicating phylogenetic analysis based on genes. This phenomenon can contribute to "incomplete lineage sorting" and is thought to be a common phenomenon across a number of groups. In species level analysis this can be dealt with by larger sampling or better whole genome analysis. Often the problem is avoided by restricting the analysis to fewer, not closely related specimens.

However, molecular analysis determined that Snyder's type collection contained two distinct species, rendering the validity of the taxon dubious. M. snyderi was also previously identified as phylogenetic species Mel-12 (i.e., defined by DNA sequence) in a 2011 study. Despite the light coloration of young fruit bodies, Morchella snyderi groups in the elata clade (named after the European black morel M. elata) along with other "black" morels such as M. angusticeps and M. tomentosa.

However, the same study also found that the magnificent frigatebird on the Galápagos Islands is genetically and morphologically distinct. Based on this study, the Galápagos population has not been exchanging any genes with their mainland counterparts for several hundred thousand years. Given these findings, the Galápagos population of this tropical seabird may be a genetically distinct species warranting a separate conservation status. This small population of genetically unique magnificent frigatebirds is vulnerable.

Shortly after its initial description, it was considered to be a southern population of the Wehrle's salamander (P. wehrlei) and was lumped in with it for many years, but a 2019 study recovered it as a distinct species, finding P. wehrlei to be a paraphyletic taxon. However, not all taxonomic issues within P. jacksoni were solved during the study, and thus P. jacksoni itself may be paraphyletic. The holotype was collected in Montgomery County, Virginia.

The genus Didymocarpus was described by Nathaniel Wallich in 1819 based on specimens he received from Nepal. Due to lack of a clear definition of the generic boundaries, more than 180 species and 450 names were affiliated to this genus over the time. These included many morphologically distinct species from Madagascar, Western ghats of India and Southeast Asia. The genus was remodeled and redefined by Weber and Burt in 1998 with about 80 species.

The lamina is green with a red midrib. Nepenthes dubia × N. izumiae differs most obviously from N. dubia in having an ovate lid that is never reflexed beyond 180 degrees. This hybrid is listed as N. dubia × N. singalana in Charles Clarke's Nepenthes of Sumatra and Peninsular Malaysia, since N. izumiae is very closely related to N. singalana and was only described as a distinct species in 2003.Clarke, C.M., T. Davis & R. Tamin 2003.

In addition to the herbarium specimens of N. eymae mentioned here, a number of others have appeared in the literature. Most authors regard N. eymae as a distinct species and it has been treated as such in all major monographs on the genus, including Matthew Jebb and Martin Cheek's "A skeletal revision of Nepenthes (Nepenthaceae)" (1997)Jebb, M.H.P. & M.R. Cheek 1997. A skeletal revision of Nepenthes (Nepenthaceae). Blumea 42(1): 1–106.

The specimen was collected from New Guinea. Nepenthes neoguineensis was described by John Muirhead Macfarlane in 1911 based on the specimen Versteeg 1746, which consists of female plant material. In 1916, Henry Nicholas Ridley described what he believed represented a male plant of N. neoguineensis. However, in his seminal monograph "The Nepenthaceae of the Netherlands Indies", B. H. Danser showed that it belonged to a closely related but distinct species, which he named N. papuana.

It is sometimes treated as a distinct species, H. gularis. Race fusca is found in Peninsular India and Sri Lanka and is slightly smaller, bluer and with a darker brown underside than the nominate race found in northwestern India. Race saturatior is found in the Andaman Islands and is larger with darker brown underparts. Race perpulchra (not always recognized) is found in northeastern India and is smaller than fusca with paler underparts.

Galeandra bicarinata is a species of orchid native to Cuba and Florida. It is closely related to G. beyrichii (widespread throughout much of South America and the Caribbean) and regarded as part of that taxon until described as a distinct species in 2000.Kew World Checklist of Selected Plant FamiliesFlora of North America v 26 p 644, Galeandra bicarinata G. A. Romero & P. M. Brown, N. Amer. Native Orchid J. 6: 78, fig. 1. 2000.

In the neo-Darwinian paradigm, one of the assumed definition of a species is that of Mayr’s, which defines species based upon sexual compatibility. Mayr’s definition therefore suggests that individuals that can produce fertile offspring must belong to the same species. However, in hybridization, two organisms produce offspring while being distinct species. During hybridization the characteristics of these two different species are combined yielding a new organism, called a hybrid, thus driving evolution.

Despite inhabiting the same hosts, T. discolor and T. ovis are distinct species. The size of male and female T. discolor whipworms are 33.9-50.68mm and 36.0—59.0mm respectively. The spicule of T. discolor is 0.94-1.30mm long and has a rounded tip, whereas the spicule of T. ovis is 4.18-5.62mm long and has a pointed tip. In addition to the spicule, the female sex organs can be used to differentiate the two species.

First described in 1884 by Lawrence as a member of the genus Engyptila, it was established as a distinct species using sonographic analysis by Blockstein and Hardy (1988). Now officially known as the Grenada dove, it was designated as the national bird in 1991 and is one of the flagship species for conservation efforts in Grenada.Butler, P., A. Joseph, and B. A Lazarus. (1992). Promoting love for the Grenada dove: Grenada’s conservation education campaign.

Rhinella pombali is a hybrid species of toad from south-eastern Brazil, named after José Perez Pombal, Jr., a Brazilian herpetologist. It was originally described in 2004 as a distinct species, but a genetic study published in 2012 found it to be a hybrid of Rhinella ornata and Rhinella crucifer; it is also morphologically intermediate between these species. It is therefore no longer considered a valid species, although it is still present in some listings.

Mocis proverai is a moth of the family Erebidae first described by Alberto Zilli in 2000. It is found in Africa and the Arabian Peninsula. In a recent publication Mocis frugalis, that is found in Asia and Australia was promoted to a separate species. Both species can be distinguished with microscopic examination of the genitalia.Zilli A. (2000) "African-Arabian and Asian- Pacific “Mocis frugalis”: Two distinct species (Lepidoptera: Noctuidae)", European Journal of Entomology, jrg.

Awaous guamensis is a species of goby native to the Pacific islands from the Marianas to Vanuatu, New Caledonia and Fiji where it can be found in fresh, brackish and marine waters. Males can reach a length of SL while females only reach . Recent work based upon morphological and genetic differences has recognized Hawaiian populations of Awaous as being distinct from Awaous guamensis. Consequently, Hawaiian Awaous are now recognized as a distinct species Awaous stamineus.

Pleistocene era fossils have been found of Bubo owls in North America, which may either be distinct species or paleosubspecies, from as far east as Georgia, but predominantly in the Rocky Mountains and to the west of them.Brodkorb, P. 1971. Catalogue of fossil birds, Part 4 (Columbiformes through Piciformes). Bulletin of the Florida State Museum, Biological Science, No. 15(4) Almost all fossils indicate these owls were larger than modern great horned owls.

Several other species were later described based on minor differences in tooth morphology. Most or all of these species have been synonymized with D. hesperus since variation in tooth morphology between individuals assigned to one of these species has proven to be to greater than the differences between species. Desmostylus japonicus was described by based on a well- preserved partial skull and named by . It has been reproposed as distinct species based on cranial morphology.

Mootnick and Groves stated that hoolock gibbons do not belong in the genus Bunopithecus, and placed them in a new genus, Hoolock. This genus was argued to contain two and later three distinct species which were previously thought to be subspecies: Hoolock hoolock, Hoolock leuconedys and Hoolock tianxing. It was later found that there is a larger evolutionary distance between these three species and the white-handed gibbons than there is between bonobos and chimpanzees.

Leptopelis christyi, also known as the Christy's tree frog or Christy's forest treefrog, is a species of frog in the family Arthroleptidae. It is known with confidence from eastern and northeastern Democratic Republic of Congo, southern and western Uganda, and northwestern Tanzania. It is likely to occur in Burundi and Rwanda, possibly ranging further in East Africa. There is an isolated population in Cameroon and Gabon that might represent a distinct species.

The dusky dolphin (Lagenorhynchus obscurus) is a dolphin found in coastal waters in the Southern Hemisphere. Its specific epithet is Latin for "dark" or "dim". It is very closely genetically related to the Pacific white-sided dolphin, but current scientific consensus holds they are distinct species. The dolphin's range is patchy, with major populations around South America, southwestern Africa, New Zealand, and various oceanic islands, with some sightings around southern Australia and Tasmania.

See also Rheindt & Austin (2005). are considered to be more significant is a matter of opinion, and the taxonomic status of these birds remains equivocal. Although some institutions (such as BirdLife International) retain the forms baroli and boydi within little shearwater, this is as a result of inaccurate lumping in the past, and is not supported by modern evidence. The British Ornithologists' Union has accepted P. baroli as a distinct species (Sangster et al.

Thymus citriodorus, the lemon thyme or citrus thyme, is a lemon-scented evergreen mat-forming perennial plant in the famly Lamiaceae. There has been a great deal of confusion over the plant's correct name and origin. Recent DNA analysis suggests that it is not a hybrid or cross, but a distinct species as it was first described in 1811.IPNI Listing T. citriodorus is an evergreen sub-shrub, growing to in height by in spread.

Meissner also described B. caleyi variety sinuosa from material collected by James Drummond, which was reviewed by Alex George and found to be no different from the other collections of B. caleyi. Drummond also collected material identified as B. caleyi that was named as a distinct species—Banksia aculeata—in 1981. No subspecies of B. caleyi itself are recognised. George Bentham published a thorough revision of Banksia in his landmark publication Flora Australiensis in 1870.

Tiger snakes (Notechis scutatus) are a highly venomous snake species found in the southern regions of Australia, including its coastal islands, such as Tasmania. These snakes are highly variable in their colour, often banded like those on a tiger, and forms in their regional occurrences. All populations are in the genus Notechis, and their diverse characters have been described in further subdivisions of this group; they are sometimes described as distinct species and/or subspecies.

More recent analysis of chromosomes reveals that the New England plants do not appear to be closely related to E. leucolepis. Eupatorium novae-angliae first formed as a hybrid between two other species, neither of them E. leucolepis. . It is self-sustaining, rather than being found only where both parents are present, so various authors since 1992 have proposed treating it as a distinct species. A formal renaming was published in 2005.

Besides Majungasaurus, fossil taxa recovered from the Maevarano include fish, frogs, lizards, snakes, seven distinct species of crocodylomorphs, five or six species of mammals, Vorona and several other birds, the possibly flighted dromaeosaurid Rahonavis, the noasaurid Masiakasaurus and two titanosaurian sauropods, including Rapetosaurus. Majungasaurus was by far the largest carnivore and probably the dominant predator on land, although large crocodylomorphs like Mahajangasuchus and Trematochampsa might have competed with it closer to water.

Now often also considered a distinct species, Homo neanderthalensis (otherwise known as Homo sapiens neanderthalensis) lived in the southern half of Poland during the Middle Paleolithic period, that is between 300,000 and 40,000 BCE. Various relics were found and different Neanderthal cultures are distinguished. Acheulean handaxes from Silesia dated 200,000-180,000 years ago are among the older tools. Gatherer-hunter sporadic groups of Neanderthals penetrated southern Poland also during the Eemian interglacial, 128,000-115,000 BCE.

Juveniles, Kihingami Wetlands near Kibale Forest, Uganda The Ugandan red colobus (Piliocolobus tephrosceles) or ashy red colobus is an endangered species of red colobus monkey, recognised as a distinct species since 2001. There is disagreement however over taxonomy with many considering the Ugandan red colobus to be a subspecies (Procolobus rufomitratus tephrosceles). The Ugandan red colobus is an Old World monkey which is found in 5 different locations across Uganda and Tanzania.

Typical silhouette The black drongo was once considered a subspecies of the fork-tailed drongo (Dicrurus adsimilis), a close relative that diverged relatively recently. The two are now considered distinct species, with the fork-tailed drongo restricted to Africa and separated from the Asian range of the black drongo. Seven subspecies have been named but the largely contiguous populations show clinal variation and intergrade with each other. Individuals from northern India (ssp.

The Huon catbird (Ailuroedus astigmaticus) is a species of bowerbird (Ptilonorhynchidae) which can be found in northeastern New Guinea. This species was formerly considered a subspecies of the spotted catbird before being reclassified as a distinct species in 2016. Martin Irestedt and colleagues examined the black-eared, spotted- and green catbird species complex genetically and found there were seven distinct lineages: the green catbird (A. crassirostris) of eastern Australia and the spotted catbird (A.

The Northern catbird (Ailuroedus jobiensis) is a species of bowerbird (Ptilonorhynchidae) which can be found in central-northern New Guinea. This species was formerly considered a subspecies of the spotted catbird before being reclassified as a distinct species in 2016. Martin Irestedt and colleagues examined the black-eared, spotted- and green catbird species complex genetically and found there were seven distinct lineages: the green catbird (A. crassirostris) of eastern Australia and the spotted catbird (A.

The black-capped catbird (Ailuroedus melanocephalus) is a species of bowerbird (Ptilonorhynchidae), native to southeastern New Guinea. This species was formerly considered a subspecies of the spotted catbird before being reclassified as a distinct species in 2016. Martin Irestedt and colleagues examined the black-eared, spotted- and green catbird species complex genetically and found there were seven distinct lineages: the green catbird (A. crassirostris) of eastern Australia and the spotted catbird (A.

Arctotis stoechadifolia, the African daisy or white arctotis, is a rare species of South African plants in the daisy family. It is a rare plant found only in sand dunes along the west coast of Cape Province.Norlindh, Nils Tycho 1965. Botaniska Notiser 118(4): 406–411 The species is sometimes regarded as the same species as the much more common and widely cultivated A. venusta, but authors separate the two as distinct species.

Springer and Bullis (1960) began to explore the possibility of only one extant Pristiophorus species worldwide, but failed to legitimize that statement due to several distinct species in our seas, one of those species being P. schroederi. The farthest lineage known goes back to early Cretaceous period, but this species (P. tumidens) is considered an offshoot of the main Pristiophorid lineage. Shown below is the phylogenetic tree of Pristiophoridae, P. schroederi on the far right.

Although older publications and some recent publications consider the I. g. boliviensis population as distinct species from Inia geoffrensis, much of the scientific community, including the IUCN, consider them to be a subspecies of Inia geoffrensis. Current classification, therefore, considers them a single species, Inia geoffrensis, in the genus Inia, with two recognized subspecies. As of 2016, the Committee on Taxonomy of the Society for Marine Mammalogy supports the designation of two subspecies.

Pupilla pratensis was originally described as a variety of Pupilla muscorum by German malacologist Stefan Clessin in 1871. The taxon Pupilla pratensis has long been neglected in the malacological literature, or considered a morphologically weakly defined ecophenotype – found in wet, calcareous habitats – of the variable Pupilla muscorum. The form, however, represents a distinct species, which has recently been shown in a study combining morphological, ecological and molecular data by von Proschwitz et al. (2007, 2009).

Julia Pastrana, "the nondescript", advertised for an exhibition of the famous bearded Lady. During her life, Pastrana's management arranged to have her examined by doctors and scientists, using their evaluations in advertisements to attract a larger audience. One doctor, Alexander B. Mott, M.D., certified that she was specifically the result of the mating of a human and an "Orang hutan". Another, Dr. S. Brainerd of Cleveland, declared that she was of a "distinct species".

Traditionally, the Ailuroedus catbirds were classified as three species. However, a phylogenetic and morphological paper by Irestedt et al. (2015). revealed seven new species, leading to a total of ten distinct species. In the same study, the results confirm that the catbirds are divided into two major clades, a lowland group consisting of the New Guinean white- eared catbird, and a mid-mountain clade including the black-eared catbird and the Australian green catbird.

Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and arable land; nonetheless, there are populations that live in urban areas, like the ever-increasing one in Santo Domingo in the Dominican Republic. The Puerto Rican parakeet (Psittacara maugei) was previously found on Mona Island, but became extinct circa 1882. It was considered a subspecies before being considered as a distinct species.

However, studies of a juvenile Byronosaurus skull showed that theropod dinosaurs possess many distinctive adult characteristics even as hatchings or embryos, and that the lack of characters solidly linking Archaeornithoides to known adult specimens shows that it is probably a distinct species. Bever and Norell (in 2009) found no evidence to support the placement of Archaeornithoides close to Avialae, and only weak support for the idea that it is a juvenile troodontid.

Weddell explored a number of regions where the trees grew and identified no fewer than fifteen distinct species of the genus Cinchona (Rubiaceae). The seeds which he took back to Paris were germinated in the Jardin des Plantes, and the plants were used to establish Cinchona forests in Java and elsewhere in the East Indies. In 1847 he married Manuela Bolognesi,Letter from Mrs. Weddell to the Society's president, 17 June 1891.

1804 illustration by Samuel Daniell, which was the basis of the supposed subspecies E. q. danielli The name "quagga" is derived from the Khoikhoi word for zebra and is onomatopoeic, being said to resemble the quagga's call, variously transcribed as "kwa-ha-ha", "kwahaah", or "oug-ga". The name is still used colloquially for the plains zebra. The quagga was originally classified as a distinct species, Equus quagga, in 1778 by Dutch naturalist Pieter Boddaert.

Later morphological studies came to conflicting conclusions. A 1999 analysis of cranial measurements found that the quagga was as different from the plains zebra as the latter is from the mountain zebra. A 2004 study of skins and skulls instead suggested that the quagga was not a distinct species, but a subspecies of the plains zebra. In spite of these findings, many authors subsequently kept the plains zebra and the quagga as separate species.

2002, page 122-3. Yet Koreans continued to plant Yoshino cherry trees and festivals began attracting a wide range of tourists. Many Korean media assert that the Yoshino cherry is the same species as a Korean indigenous, endangered species called King cherry, whose mass production is still being studied. In 2007, a study conducted on the comparison of King cherry and Yoshino cherry concluded that these trees were categorized as distinct species.

The background body colour is translucent white with dense punctuation of very small red-orange dots. The mantle edge is trimmed with small tubercles tipped with orange to red dots. Rhinophores and gills are retractable, translucent and speckled with dark spots. Animals from East Africa differ in having lines or more continuous brown pigment on the rhinophores and gills instead of spots and are considered to be a distinct species by some authorities.

A trend in this genus to lose—not gain—pronounced sexual dimorphism is better supported by biogeographical and molecular data than the alternate scenario. In 2010 the IOC World Bird List listed the Hainan peacock-pheasant as a species. Following Jean Théodore Delacour, this species has historically been listed as a subspecies of P. bicalcaratum. Prior to reclassification by Delacour, the Hainan peacock-pheasant has been considered a distinct species by several ornithologists.

Deepsea lizardfishes were first described in 1878 by British zoologist Albert Günther, who created the generic name from ancient Greek word elements “báthos” and “saûros” meaning “lizard of the depths”. Previously recognized in the synodontidae, in 1996, Robert Karl Johnson et al. showed its relationships outside synodontidae, in its own family in the suborder Giganturoidei. At the beginning of the century, Bathysaurus ferox larvae were thought to be a distinct species called Macristium chavesi.

In an extensive study of the Stromboidea in 2005, Simone provisionally treated these as distinct species, but observed, "no spectacular morphological difference was found [and] all related differences, even those of the genital system, can be regarded as extreme of variation of a single, wide distributed, variable species." Simone (2005): Comparative Morphological study of representatives of the three families of Stromboidea and the Xenophoroidea (Mollusca, Caenogastropoda), with an assessment of their phylogeny , p. 169.

The bluebuck (Afrikaans: bloubok ) or blue antelope (Hippotragus leucophaeus) is an extinct species of antelope that lived in South Africa until around 1800. It is congeneric with the roan antelope and sable antelope (belonging in the genus Hippotragus), but was smaller than either. It was sometimes considered a subspecies of the roan antelope, but a genetic study has confirmed it as a distinct species. The largest mounted bluebuck specimen is tall at the withers.

Fortune named the species after Beale in an issue of the Gardeners' Chronicle and was sure it was a distinct species, separate from Mahonia japonica. However, Chronicle editor John Lindley, was unconvinced and repeatedly referred to the new species as Berberis (Mahonia) japonica. The confusion between M. japonica and M. bealei is reflected in subsequent literature, with the latter referred to variously as M. japonica var. bealei, M. japonica ‘Bealei’ or M. japonica Bealei Group.

Thus, N. ashei was only classified as a distinct species in 2007, by Wolfgang Wüster (Bangor University, Wales) and Donald Broadley (Biodiversity Foundation for Africa). Royjan Taylor (Director of the Bio-Ken Snake Farm in Watamu, Kenya) was instrumental in providing specimens, among them the holotype. The giant spitting cobra is most closely related to the Mozambique spitting cobra (N. mossambica), which with this species forms a sister taxon to N. nigricollis.

Kosswig's smooth newt (Lissotriton kosswigi) is a newt species found in northwestern Anatolia, east of the Bosphorus. Günther Erich Freytag described the species in 1955 as Triturus vulgaris kosswigii, a subspecies of the smooth newt (now Lissotriton vulgaris). After genetic data had suggested the smooth newt was a complex of distinct lineages, Dubois and Raffaëlli, in 2009, recognised several subspecies, including Kosswig's smooth newt, as distinct species. This was followed by subsequent authors.

Macrolepiota clelandii was officially described by mycologist Cheryl Grgurinovic in her 1997 work Larger Fungi of South Australia. Before this, Australian naturalist John Burton Cleland had referred the fungus to Macrolepiota procera, a widespread, common species that is now known to not occur in Australia. Grgurinovic identified Cleland's taxon, characterised by having two-spored basidia, as a distinct species. The type collection was made by Cleland in 1912, near Hawkesbury River in New South Wales.

It has extensive mangrove swamps and attracts a wide variety of water birds. The lagoon supports so many distinct species of flora, fauna and as well as another species of birds and variety of animals. Negombo Lagoon is a major local and tourist attraction primarily for sightseeing and boating tours. The fishermen who are based at the Negombo lagoon live in abject poverty in shanty thatch palm villages along the water's edge.

Meanwhile, Kew Gardens distributed plants it had propagated to British colonies throughout the world. Soon thereafter, a crimson specimen in Cartagena, Colombia was added to the genus descriptions. Originally thought to be a distinct species, it was named B. buttiana in honour of the European who first encountered it. However, later studies classified it as a natural hybrid of a variety of B. glabra and possibly B. peruviana - a "local pink bougainvillea" from Peru.

Trichoderma longibrachiatum is a fungus in the genus Trichoderma. In addition to being a distinct species, T. longibrachiatum also typifies one of several clades within Trichoderma which comprises 21 different species. Trichoderma longibrachiatum is a soil fungus which is found all over the world but mainly in warmer climates. Many species from this clade have been adopted in various industries because of their ability to secrete large amounts of protein and metabolites.

However, in 2007, Brian Keener and Larry Davenport published a treatment of the fertile individuals as a distinct species, which they named A. tutwilerae for the original discoverer. They argued that as a fertile, reproductively isolated population sharing a common origin, the fertile individuals were consistent with several popular biological species concepts, and warranted recognition as a species. The segregation of A. tutwilerae from A. × ebenoides made it one of the rarest fern species worldwide.

The base form of species Floccularia luteovirens is similar in appearance, but can be distinguished from F. albolanaripes by its brighter yellow cap color with raised scales on the surface, and yellowish gills. F. luteovirens forma straminea (which has sometimes been defined as a distinct species, F. straminea) is another lookalike with similar coloration and habitat preferences, but its cap features shaggy scales arranged in concentric zones, and it has light yellow gills.

Once thought to be a color morph of the painted maskray (N. leylandi), the peppered maskray was recognized as a distinct species based on molecular data collected for the Barcode of Life project. It was described by Peter Last and William White in a 2008 Commonwealth Scientific and Industrial Research Organisation (CSIRO) publication. Their account was based on 13 specimens; of these, a female across caught off Rockhampton, Queensland was designated as the holotype.

In 2001, genetic evidence emerged that the African elephant (Loxodonta africana), once thought to be a single species, was in fact two, as the smaller African forest elephant was in fact a distinct species (Loxodonta cyclotis). L. africana is now commonly referred to as the African bush elephant. Strictly speaking, this is not a newly discovered species, but simply an alternative taxonomic treatment, as cyclotis already was widely recognized, but only as a subspecies.

Brown bears originated in Eurasia and traveled to North America approximately 50,000 years ago, spreading into the contiguous United States about 13,000 years ago. The genome of the grizzly bear was sequenced in 2018 and found to be 2,328.64Mb (mega- basepairs) in length, and contain 30,387 genes. In the 19th century, the grizzly was classified as 86 distinct species. However, by 1928 only seven grizzly species remained, and by 1953 only one species remained globally.

Aerococcus urinae is a member of the bacterial genus Aerococcus. The bacterium is a Gram-positive, catalase- negative coccus growing in clusters. Isolates of this genus were originally isolated in 1953 from samples collected in the air and dust of occupied rooms and were distinguished by their tetrad cellular arrangements. Later, it was found in the urine of patients with urinary tract infections and in 1992, A. urinae was assigned as distinct species.

The first collections of G. hyalelloides were made in 1967 at the Phantom Lake Spring. The amphipods were originally thought to be the common and widespread Hyalella azteca, but were later recognized as a new and distinct species of Gammarus. The type specimens were deposited in the United States National Museum (holotype male: USNM 151957; paratype female: USNM 151958). Further paratype series were deposited at the same museum, and at the National Museum of Canada.

It listed 17 species in the genus, 10 from Madagascar and 7 from central Africa. 20 species were listed in 1934, of which 14 were from Madagascar and only 6 from central Africa. By 1976, the number had returned to 17, with 12 of those being from Madagascar and 5 from central Africa. Several new species were added in the 1990s, and several classifications previously reduced to synonym or subspecies were elevated to the status of distinct species.

The southern dark newtonia (Newtonia lavarambo) is a species of bird in the family Vangidae. It is endemic to the montane forests of southeastern Madagascar, from Andringitra south to Tolagnaro. It was formerly considered a population of the dark newtonia (N. amphicroa) (now referred to as the northern dark newtonia), but was split from it in 2018 and classified as a distinct species after an analysis of physical and genetic differences from N. amphicroa, most notably its longer tail.

Pleurotus purpureo-olivaceus is a gilled fungus native to Australia and New Zealand. It is found on dead wood of Nothofagus trees. Although morphologically similar to some other Pleurotus fungi, it has been shown to be a distinct species incapable of cross-breeding and phylogenetically removed from other species of Pleurotus. The caps of the fruit bodies are up to wide, and are dark violet to brown to olive to yellow-green, depending on light exposure.

The closure turns the carboxyl carbon into a chiral center, which may have any of two configurations, depending on the position of the new hydroxyl. Therefore, each hexose in linear form can produce two distinct closed forms, identified by prefixes "α" and "β". It has been known since 1926 that hexoses in the crystalline solid state assume the cyclic form. The "α" and "β" forms, which are not enantiomers, will usually crystallize separately as distinct species.

British zoologist Oldfield Thomas first described the royal vole was in 1907 as Craseomys regulus, the type locality being Mingyong in Korea, south east of Seoul. It was later transferred to the genus Myodes, becoming Myodes regulus, but many authorities believed it was a subspecies of Myodes rufocanus. It has unrooted molar teeth, a characteristic shared by the very similar Myodes shanseius but not M. rufocanus, and molecular analysis shows that it is a distinct species.

In some cases, pollen grains are morphologically indistinct even among different genera within the same plant family. As a result, fossil pollen often results in "taxonomic smoothing" that inhibits fine-scale resolution of past vegetation to the species level. However, examples of Picea pollen being identified as morphologically distinct, species-level units exist. Pollen from Picea glauca, Picea rubens, and Picea mariana has been characterized, classified, and assessed with relative accuracy based on distinct morphological attributes of each species.

Ambloplites constellatus (Ozark bass), a species of rock bass from the Ozark upland of Arkansas, and Ambloplites ariommus (shadow bass) are true rock bass, but regarded as separate species. Ambloplites rupestris is sometimes called the redeye or redeye bass in Canada, but this name refers more properly to Micropterus coosae, a distinct species of centrarchid native to parts of the American South. Rafinesque originally assigned the rock bass to Bodianus, a genus of marine wrasses (family Labridae).

Simultaneously, they described the S. lakei variety pseudopictus that they said had been misidentified by collectors as Suillus pictus (now called Suillus spraguei) because of its reddish and scaly cap. Singer considered Suillus amabilis to be the same species as S. lakei, but Smith and Thiers later examined the type material of both, and concluded that they were distinct species. Engel and colleagues described a variety in 1996, S. lakei var. landkammeri, based on Boletinus tridentinus subsp.

Three taxa were excluded: N. cincta, N. cristata, and N. lindleyana. Three widespread natural hybrids were also covered. Jebb and Cheek revised several of the taxonomic determinations made in B. H. Danser's influential 1928 monograph, "The Nepenthaceae of the Netherlands Indies". This included the recognition of N. eustachya, N. hispida, N. ramispina, and N. sumatrana as distinct species, whereas previously they had been treated as heterotypic synonyms of N. alata, N. hirsuta, N. gracillima, and N. treubiana, respectively.

Juniperus excelsa, commonly called the Greek juniper, is a juniper found throughout the eastern Mediterranean, from northeastern Greece and southern Bulgaria across Turkey to Syria and Lebanon, Jordan and the Caucasus mountains. A subspecies, J. excelsa subsp. polycarpos, known as the Persian juniper, occurs in the Alborz and other mountains of Iran east to northwestern Pakistan, and an isolated population in the Jebal Akhdar mountains of Oman; some botanists treat this as a distinct species, J. macropoda.

The genus Cyanoramphus is endemic to New Zealand and surrounding islandsKearvell, J; Grant, A; Boon, W (2003). "The orange-fronted parakeet (Cyanoramphus malherbi) is a distinct species: a review of recent research on its taxonomy and systematic relationship within the genus Cyanoramphus". Notornis, 50: 27–35 and it has been proposed that the ancestor of Cyanoramphus dispersed from New Caledonia to New Zealand via Norfolk Island 500,000 years ago.Boon, W; Kearvell, J; Daugherty, C; Chambers, G. (2001).

The first description of a spider now assigned to this species was by Carl Ludwig Koch in 1843, under the name Tegenaria atrica. Other supposedly different species were described later, including Tegenaria saeva by John Blackwall in 1844, Tegenaria duellica by Eugène Simon in 1875 and Tegenaria gigantea by Ralph Vary Chamberlin and Wilton Ivie in 1935. T. gigantea was synonymized with T. duellica in 1978. The three remaining taxa have been regarded as distinct species, particularly in Britain.

The Cypriot mouse has characteristics that distinguish it from other European mice: bigger ears, eyes and teeth;DNA tests confirmed that it was a distinct species. It is native to Cyprus. "All other endemic mammals of Mediterranean islands died out following the arrival of man, with the exception of two species of shrew. The new mouse of Cyprus is the only endemic rodent still alive, and as such can be considered as a living fossil," said Dr. Cucchi.

The three-spined stickleback (Gasterosteus aculeatus) Another possible cause for despeciation is increased gene flow and hybridization due to changes in the environment. One of these changes could include the loss of essential nourishment resources for each individual species. For example, Taylor et al.'s genetic analysis of three-spined sticklebacks across six lakes in southwestern British Columbia found two distinct species in 1977 and 1988 but only one combined species in data from 1997, 2000, and 2002.

Adetomyrma cassis is only known from a single male collected in the Ambatovaky Reserve, Madagascar. The male of A. cassis is distinguished easily from other Adetomyrma males by a distinct and flatted projection on the posterior portion of the paramere. This projection is not separated from the paramere by a deep notch as in A. bressleri. This genital character observed in Adetomyrma cassis is completely unique and sufficient to regard this male as a distinct species.

Cicindela albissima has been proposed to be listed as under the Endangered Species Act. It was previously considered a subspecies of Cicindela limbata, but it is over from any other populations of C. limbata. Its geographic isolation, mtDNA, and morphological differences, particularly the coloration of the elytra and body size, led it to be considered a distinct species. In 2012, the population of C. albissima was estimated to be 1786 individuals, up from 1116 in 2011.

Phylogenetic analysis of the three confirmed Epsilonretroviruses shows they are related. After cloning techniques, sequence analysis determined that WEHV-1 and WEHV-2 are similar in size and share 95% amino acid identity in the pol region of reverse transcriptase. This finding suggests that they are different strains of the same virus or likely distinct species. The two types of WEHV also share over 80% of their amino acid sequence with the third member of the epsilonretrovirus genus.

In their description of Paeonia lutea var. ludlowii, these authors indicate that it is distinctly different from variety lutea. Recent analysis shows that these differences between ludlowii and the other described taxa in the P. delavayi-group are consistent whilst the character states within the other taxa occur in any combination. Therefore Hong concludes that ludlowii should be acknowledged as a distinct species, while the other taxa cannot be upheld and should be synonymized with P. delavayi.

Most are small, but an unnamed form dating to 15–16 mya is comparable in size to the largest living slow lorises. Molecular clock analysis suggests that slow lorises may have started evolving into distinct species about 10 mya. They are thought to have reached the islands of Sundaland when the Sunda Shelf was exposed at times of low sea level, creating a land bridge between the mainland and islands off the coast of Southeast Asia.

In 1973, B.C. Stone argued that F. banksii should be regarded as a subspecies of F. baueriana of Norfolk Island (Stone 1973). Subsequent to this, de Lange et al. (2005:591-592), countered Stone's arguments and retained F. banksii as a distinct species because of significant differences from F. baueriana, including over all growth habit, phyllotaxis, leaf width, vein tessellation, and bract colour (salmon pink to orange in F. baueriana, white to purplish in F. banksii).

Amanita regalis was first described as Agaricus muscarius β regalis by Elias Magnus Fries in his Systema Mycologicum, published in 1821. In 1887, Pier Andrea Saccardo treated it as a variety of Amanita muscaria. Edmund Michael, in 1903, became the first to consider it a distinct species. In 1941, Jean-Edouard Gilbert suggested a complete reorganization of the genus Amanita in his world monograph of the genus, and moved it to Amanitaria as A. muscaria var. regalis.

The Aldabra giant tortoise has an unusually long history of organized conservation. Albert Gunther of the British Museum, who later moved to the Natural History Museum of London (enlisting Charles Darwin and other famous scientists to help him) worked with the government of Mauritius to establish a preserve at the end of the 19th century. The related, but distinct, species of giant tortoise from the Seychelles islands (Seychelles giant tortoise A. g. hololissa and Arnold's giant tortoise A. g.

The genus was circumscribed in 1985 to contain the species originally described as Agaricus lignatilis by Christian Hendrik Persoon in 1801. This was considered the sole species in the genus until 2007, when Marco Contu validly published a description of O. lachnopus from collections in Italy. Recent analysis (2013) confirms that O. lachnopus and O. lignatilis should be considered distinct species. Molecular genetics analysis suggests that Ossicaulis is most closely related to the genera Asterophora, Hypsizygus, Lyophyllum, and Tricholomella.

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.

Gould met Darwin and told him that the Galápagos mockingbirds from different islands were separate species, not just varieties, and what Darwin had thought was a "wren" was also in the finch group. Darwin had not labelled the finches by island, but from the notes of others on the ship, including FitzRoy, he allocated species to islands. The two rheas were also distinct species, and on 14 March Darwin announced how their distribution changed going southwards. evolutionary tree.

As in N. dubia, the stem and tendrils are purplish-red. The lamina is green with a red midrib. Nepenthes dubia × N. izumiae differs most obviously from N. dubia in having an ovate lid that is never reflexed beyond 180 degrees. This hybrid is listed as N. dubia × N. singalana in Charles Clarke's 2001 monograph, Nepenthes of Sumatra and Peninsular Malaysia, because at the time of its publication it was uncertain whether N. izumiae represented a distinct species.

Common dolphin, Ireland Despite the historic practice of lumping the entire genus Delphinus into a single species, these widely distributed dolphins exhibit a wide variety of sizes, shapes and colors. Indeed, over the past few decades, over 20 distinct species in the genus have been proposed. Scientists in California in the 1960s concluded there were two species — the long-beaked and short-beaked. This analysis was essentially confirmed by a more in-depth genetic study in the 1990s.

Notoliparis antonbruuni is a species of snailfish. It was described in 2005 from a single poorly preserved specimen collected in 1966 from the hadal zone off Callao, Peru. Despite its poor condition, this specimen clearly represents a distinct species although it was unclear which genus the species should be placed in. Notoliparis was chosen rather than Careproctus or Pseudoliparis due to the location the new species was collected being close to the distribution of other Notoliparis species.

The two male forms look and behave so differently that they were originally considered two distinct species. In 1955 Robert Barnes chose M. inclemens, and this has become the standard name. The species is found in west southern Canada, and in the United States its distribution forms a crescent from the north mid-west through New England and south to Florida. M. inclemens has been able to establish itself in man-made structures such as outbuildings or fences.

The coast horned lizard (Phrynosoma coronatum) is a species of phrynosomatid lizard which can be found in Baja California Sur. The old classification included all three current species P. blainvillii, P. cerroense, and P. coronatum as a single species (P. coronatum) ranging from Baja California north to California's Sacramento Valley. It was previously considered to be a widely divergent species with over 6 subspecies in their relatively small range but is now classified as three distinct species.

Nyctimystes perimetri, also known as the archipelago big-eyed treefrog, is a species of frog in the family Pelodryadidae, also treated as the subfamily Pelodryadinae in the family Hylidae. It is endemic to Papua New Guinea and currently only known from the Louisiade Archipelago (Tagula and Rossel Islands), although it might also occur in the Owen Stanley Range of the mainland Papua New Guinea. It has also been suggested that the Rossel Island population might represent a distinct species.

This morph is recessively inherited. This morph occurs in the amago subspecies (Oncorhynchus masou ishikawae) in Western Japan, and apparently also in the nominate subspecies yamame (Oncorhynchus masou masou), if these are not identical. The morph was scientifically described as a distinct species Oncorhynchus iwame in 1961 by Kimura & Nakamura. In the 2000s, the iwame morph was shown to occur as a polymorphism in random mating populations of O. masou, and is no more thought to have taxonomical value.

They confirmed the genetic difference of the two species by the means of protein electrophoresis. In 1990, Sibley and Monroe accept the two as distinct species. Molecular sequence divergence studies indicate that this species along with the Indian siverbill are basal, having diverged from the common ancestors of other Lonchurae about 11 MYA. This and other evidence including differences in the arrangement of down in chicks and behaviour leads some authors to placing them in the separate genus Euodice.

Female This species is of class Insecta, order Hymenoptera, and family Apidae. Although closely related to Bombus terricola, DNA evidence supports that they are a distinct species. Evidence of a subspecies divide is found through examination of the COI-barcode of the bees, suggesting that Bombus occidentalis can be divided between the northern and southern population. The supposed subspecies each have specific haplotype groups, which is reflected by the differences in hair length between the populations.

Nymphargus mariae, commonly known as Maria's giant glass frog, is a species of frog in the family Centrolenidae. It is found in the cloud forests of the Serranía de Sira, Huánuco, Peru and in Ecuador. A population endemic to Ecuador was previously considered to be a distinct species, Nymphargus puyoensis, but is now classified as a junior synonym. Its natural habitats are the cloud forests of the Serranía de Sira and lower montane wet forests of Ecuador.

The African forest elephant was long considered to be a subspecies of the African elephant, together with the African bush elephant. Morphological and DNA analysis showed that they are two distinct species. The taxonomic status of the African pygmy elephant (Loxodonta pumilio) was uncertain for a long time. Phylogenetic analysis of the mitochondrial genome of nine specimens from museum collections indicates that it is an African forest elephant whose diminutive size or early maturity is due to environmental conditions.

The brown long-eared bat or common long-eared bat (Plecotus auritus) is a small Eurasian insectivorous bat. It has distinctive ears, long and with a distinctive fold. It is extremely similar to the much rarer grey long-eared bat which was only validated as a distinct species in the 1960s. An adult brown long-eared bat has a body length of 4.5-4.8 cm, a tail of 4.1-4.6 cm, and a forearm length of 4-4.2 cm.

Megalochelys atlas is an extinct species of giant cryptodiran tortoise from the Late Miocene through to the Early Pleistocene periods. During the dry glacial periods it ranged from western India and Pakistan (possibly even as far west as southern and eastern Europe) to as far east as Sulawesi and Timor in Indonesia, though the island specimens likely represent distinct species. It has been suggested that Megalochelys sivalensis is the correct name for the taxon, though this is disputed.

The London Underground mosquito is a form of mosquito in the genus Culex. It is found in the London Underground railway system as its name suggests, but has a worldwide distribution and long predates the existence of the London Underground. It was first described as a distinct species from Egyptian specimens by the biologist Peter Forsskål (1732–1763). He named this mosquito Culex molestus due to its voracious biting, but later biologists renamed it Culex pipiens f.

The Mérida brocket (Mazama bricenii), also known as the Meroia brocket or rufous brocket, is a small species of deer. It is found in forest and páramo at altitudes of in the Andes of northern Colombia and western Venezuela. It was once treated as a subspecies of the similar little red brocket, but has been considered a distinct species since 1987, though as recent as 1999 some maintained it as a subspecies.Nowak, R. M. (eds) (1999).

It was first described by science in the 1797 second edition of The Natural History of Aleppo, a book written and edited by two Scottish physicians living in Syria. The Syrian hamster was first recognized as a distinct species in 1839. In 1930, a scientist seeking animal subjects for medical research had the first Syrian hamsters captured to become laboratory animals. Scientists bred those hamsters and during the 1930s sent their descendants to various other laboratories around the world.

Nematocysts are found in the epidermal mucus coat of several nudibranch families. The amount of inhibition ranges based on the different species of sea anemones preyed upon. By consuming distinct species, the outer mucous layer inhibition alters but if two separate prey species are constantly eaten, the mucous layer will inhibit for both species. Anemones are also covered with a protective mucous layer that is compositionally unique from the mucous layer that is produced by nudibranch species.

The common bush tanager (Chlorospingus flavopectus), also referred to as common chlorospingus, is a small passerine bird. It is a resident breeder in the highlands from central Mexico south to Bolivia and northwest Argentina. C. flavopectus in the loose sense is a notorious cryptic species complex, and several of the up to 25 subspecies recognized in recent times are likely to be distinct species. Some populations in fact appear to be more distinct than several other members of Chlorospingus.

The Cuban greater funnel-eared bat (Natalus primus), described in 1919, has been considered a subspecies of N. major: N. major primus, but is now recognised as a different species by the IUCN. Similarly, N. major jamaicensis, described in 1959, is now recognised as a distinct species: Natalus jamaicensis. Previous reports of Natalus on the island had also been referred considered Natulus major. The genus Natalus was traditionally placed into three subgenera: Natalus, Chilonatalus and Nyctielleus.

The Sichuan treecreeper (Certhia tianquanensis) is a rare species of bird in the treecreeper family, Certhiidae. It was described as new to science (initially as a subspecies of the common treecreeper C. familiaris) in 1995 from 14 specimens taken at four sites in the mountains of western Sichuan, China. In 2002, it was realized that these birds constituted a distinct species, and subsequent researchTietze et al. (2006) suggests it is closest to the Nepal treecreeper (C. nipalensis).

In Pakistan, the breeding range of the dusky crag martin overlaps that of the subspecies P. f. peloplasta of pale crag martin, but that species breeds much higher in the mountains. This altitudinal separation means that it is not known whether the two closely related martins could hybridise, which would cast doubts as to whether they were distinct species. Dusky crag martins from Burma and Thailand have been described as a separate darker subspecies, P. c.

While D. albomicans and Drosophila nasuta are commonly referred to as distinct species, there appears to be little to no sexual isolation between these two Drosophila species. Instead, behavioural differences appear to reproductively isolate these two species. The Immigrans species group (to which D. albomicans belongs) is related to the Drosophila quinaria and Drosophila testacea species groups. The related species Drosophila immigrans has been used in evolutionary studies to understand how viruses evolve with their hosts.

Boletus rubriceps is a species of bolete fungus in the family Boletaceae. Although it was officially described as new to science in 2014, the bolete had previously been reported as either Boletus edulis or B. pinophilus. Molecular analysis showed that it was sufficiently different from other morphologically similar Boletus species to warrant designation as a distinct species. It is found in the southwestern United States and southern Rocky Mountains, where it associates with spruce, pine, and sometimes fir.

The grey-hooded fulvetta (Fulvetta cinereiceps) is a bird species in the family Sylviidae. Like the other typical fulvettas, it was long included in the Timaliidae genus Alcippe. Formerly, F. cinereiceps was known as Manipur fulvetta, the birds properly referred to with this name have been split off and are now usually treated as a distinct species, F. manipurensis. Another former subspecies of F. cinereiceps that is nowadays usually considered distinct is the Taiwan fulvetta (F. formosana).

The bird has several subspecies. The Rodrigues pigeon, an extinct but fairly enigmatic taxon from Rodrigues on the Mascarenes, was for some time suspected to be another subspecies of N. picturata, but today is generally considered a distinct species (N. rodericanus). The pink pigeon (N. mayeri) is its closest living relative, and together they form a lineage apart from both the typical pigeons (Columba) and the typical turtle doves (Streptopelia), slightly closer to the latter, if anything.

Many taxa are triploid. Boechera is a primarily North American genus, most diverse in the western United States but its distribution range also includes Greenland and the Russian Far East. The genus is poorly known, and species within are difficult to separate morphologically though some clearly distinct species are known. Most members of the genus are perennial plants with pubescent leaves with stellate trichomes, narrow curving fruits, and small white to purple flowers in elongated racemes.

Bouvier's red colobus was first described in 1887 by Alphonse Trémeau de Rochebrune in Faune de Sénégambie. For many years it was considered a subspecies of Pennant's colobus and named Procolobus pennantii ssp. bouvieri. In 2007, Colin Groves reclassified it as a distinct species. Groves considers Piliocolobus to be a full genus, while other authors see it as a subgenus of Procolobus, and thus assigned Bouvier's red colobus the scientific name Piliocolobus bouvieri (this nomenclature has been followed here).

Allium ochotense, the Siberian onion, is a primarily East Asian species of wild onion native to northern Japan, Korea, China, and the Russian Far East, as well as on Attu Island in Alaska. Some authors have considered A. ochotense as belonging to the same species as A. victorialis,Flora of China Vol. 24 Page 172 茖葱 ge cong Allium victorialis Linnaeus, Sp. Pl. 1: 295. 1753. but more recent authorities have treated it as a distinct species.

This species was originally described by Franz Werner in 1894 based on a specimen with no other collection information than its origin, "S. Amerika". In 1981 designated a neotype for the species, erroneously believing that the holotype (the only known specimen, in the collections of the Institut für Zoologie der Universität Wien) was lost. However, the neotype specimen was not a hylid but a centrolenid, later described as a distinct species, Centrolenella savagei (now synonym of Ikakogi tayrona).

Feihyla hansenae, also known as Hansen's Asian treefrog, Hansen's bushfrog, and Chon Buri pigmy tree frog, is a species of frog in the family Rhacophoridae. As its range is currently known, it is endemic to Thailand, although it is likely that its true range extends into Myanmar, Cambodia, and Laos. The nominal species consists of two lineages that may represent distinct species. The specific name hansenae honours Dora Hansen, friend of Doris Mable Cochran who described this species.

The national park is quite diverse in its wildlife and vegetation, hosting approximately 804 distinct species of plants, 256 bird species, and an otherwise considerable variety of mammals, reptiles, and marine life. The entirety of the national park, including both Dilek Peninsula National Park and Büyük Menderes Delta National Park, is currently protected under the Ramsar Convention, the Berne Convention on the Conservation of European Wildlife and Natural Habitats, the Rio Convention on Biological Diversity, and the Barcelona Convention.

Blackberries are a source of polyphenols A polyphenol antioxidant is a hypothetical type of antioxidant containing a polyphenolic substructure and studied in vitro. Numbering over 4,000 distinct species mostly from plants, polyphenols may have antioxidant activity in vitro, but are unlikely to be antioxidants in vivo. Hypothetically, they may affect cell-to-cell signaling, receptor sensitivity, inflammatory enzyme activity or gene regulation, although high-quality clinical research has not confirmed any of these possible effects in humans .

After genetic data had suggested the smooth newt was a complex of distinct lineages, Dubois and Raffaëlli, in 2009, recognised several subspecies, including the Caucasian smooth newt, as distinct species. This was followed by subsequent authors. The species differs from other species in the smooth newt species complex mainly in the male secondary characters during breeding season. The dorsal crest in males reaches 1 mm or more in height and has an almost spine-shaped denticulation.

With corals, fragments are taken and stored in water tanks under controlled conditions. Genetic material in a 'gene bank' is preserved in a variety of ways, such as freezing at -196° Celsius in liquid nitrogen, being placed in artificial ecosystems, and put in controlled nutrient mediums. Accession is the common term given to an individual sample in a gene bank, such as a distinct species or variety. In plants, it is possible to unfreeze the material and propagate it.

They are characterised by a black, oval carapace (to 130 cm) that is domed, higher in the centre than in the front, and broad anteriorly. In 2015, the small, eastern Cerro Fatal population of the island was described as a distinct species, C. donfaustoi, most closely related to chathamensis (and forming a clade with it plus abingdoni and hoodensis), while the main southwestern porteri population was found to be closer to the Floreana and southern Isabela tortoises.

A form with rayless flowers is sometimes considered a distinct species. Grindelia squarrosa, also known as a curly-top gumweed or curlycup gumweed, is a small North American biennial or short-lived perennial plant. It is native to western and central North America, from British Columbia east to Québec and New England, and south as far as California, New Mexico, Arizona, Chihuahua, and Texas. The species may possibly be naturalized in much of the eastern part of that distribution.

The blue wildebeest was at first placed under a separate genus, Gorgon, while the black wildebeest belonged to the genus Connochaetes. Today, they are united in the single genus Connochaetes, with the black wildebeest being named (C. gnou) and the blue wildebeest (C. taurinus). According to a mitochondrial DNA analysis, the black wildebeest are estimated to have diverged from the main lineage during the Middle Pleistocene and became a distinct species around a million years ago.

Ferox trout (Salmo ferox) is a variety of trout found in oligotrophic lakes/lochs of Ireland, England, Scotland and Wales. Ferox trout is a traditional name for large, piscivorous trout, which in Scotland feed largely on Arctic char. It has been argued to be a distinct species, being reproductively isolated from "normal" brown trout (Salmo trutta) of the same lakes, particularly in Ireland. However, it is uncertain whether the ferox of different lakes are all of a single origin.

This species was first described by Nikolay Alekseyevich Bobrinski in 1926. The genus Hypsugo was previously considered to be within Pipistrellus, but is now considered distinct. This species was previously considered to be a subspecies of H. savii, but is now considered a full species. The taxonomic status of the Korean population of H. alaschanicus is unclear, with it sometimes being considered as a subspecies, and it being considered as a distinct species called H. coreensis by other authors.

Jussieu, A.L. de. Genera Plantarum The genus was subsequently spelled in several ways until it was finally established as "Bougainvillea" in the Index Kewensis in the 1930s. Originally, B. spectabilis and B. glabra were undifferentiated until the mid-1980s when botanists classified them as distinct species. In the early 19th century, these two species were the first to be introduced into Europe, and soon, nurseries in France and Britain sold these varieties in Australia and throughout their former colonies.

The red- naped sapsucker is one of four North American woodpeckers in the genus Sphyrapicus. It has no subspecies. First described by Spencer Fullerton Baird in 1858, it was initially thought to be a subspecies of the yellow-bellied sapsucker. However, there are significant genetic differences between this species and the yellow-bellied sapsucker, and the American Ornithologists' Union recognized it as a distinct species in the seventh edition of its North American birds checklist, published in 1998.

Hedera rhombea, the Japanese ivy or songak, is a species of ivy in the Araliaceae family native to East Asia. Formerly named Hedera pedunculata, some subspecies could be subsequently classified as a distinct species. It is common on rocky slopes and growing up the trunks of trees, especially in laurel forest, a type of cloud forest. Hedera rhombea is found in Japan, the Korean Peninsula, islands between Korea and Japan, the coast of mainland China and Taiwan.

The Singapore whiskered bat (Vespertilio oreias) is or was a possible species of vesper bat endemic to Singapore. No specimens have been found since its original scientific description in 1840 by Dutch zoologist Coenraad Temminck. Modern analysis of the type specimen found it to have skull fragments from another species and the skin to be in too poor a condition to confirm as distinct species. The holotype specism is in Naturalis Biodiversity Center in Leiden, Netherlands.

Scuticociliatosis is a severe and often fatal parasitic infection of several groups of marine organisms. Species known to be susceptible include a broad range of teleosts, seahorses, sharks, and some crustaceans. The disease can be caused by any one of about 20 distinct species of unicellular eukaryotes known as scuticociliates, which are free-living marine microorganisms that are opportunistic or facultative parasites. Scuticociliatosis has been described in the wild, in captive animals in aquariums, and in aquaculture.

One of the most recently described Banksia species, it was probably seen by Edward John Eyre in 1841, but was not collected until 1973, and was only recognised as a distinct species in 1988. There has been very little research on the species since then, so knowledge of its ecology and cultivation potential is limited. It is placed in Banksia ser. Cyrtostylis, alongside its close relative, the well- known and widely cultivated B. media (southern plains banksia).

Franklin's grouse (F. franklinii) of British Columbia and the Rocky Mountains was recently split as a distinct species from Falcipennis canadensis and also consists of the subspecies isleibi in Prince of Wales Island and nearby Alexander Archipelago in southeast Alaska. It closely resembles the Spruce Grouse but the male's tail is entirely black lacking the chestnut terminal tail band of the Spruce Grouse, and has white spots overlying it. Territorial males are notable for their wing-clap display.

The genus Margarya was described by Nevill (1877) based on shells of the type species collected by A.R. Margary from Lake Erhai, the type locality of Margarya melanioides. Based on shell and radular morphology, Tchang & Tsi (1949) revised this genus for the first time and recognized seven distinct species. He created two subgenera of Margarya , viz Tchangmargarya and Mabillemargarya. The first molecular phylogeny showed that the genus Margarya is polyphyletic and divided into three distinct clades.

Beggar lice seeds readily stick to many objects, such as this shoe The taxonomy and systematics of the many dozens of Desmodium species are confusing and unresolved. Related genera such as Codariocalyx, Hylodesmum, Lespedeza, Ohwia, and Phyllodium were and sometimes still are included in Desmodium.ILDIS (2005) Taxonomic authorities commonly disagree about the naming and placement of species. For example, Desmodium spirale as described by August Grisebach might refer to a distinct species, but its validity is doubtful.

The length of the shell attains 23 mm, its diameter 9.5 mm. The species was described from a young shell which is not in very good condition. The form now described as a variety may prove to be a distinct species. In fresh condition the shell is of an olive-green tint, with a brown area either covering the larger and lower portion of the body whorl or confined to a small region at the base.

Gilmoreosaurus (meaning "Charles Whitney Gilmore's lizard") is the name given to a genus of dinosaur from the Cretaceous of Asia. The type species is Gilmoreosaurus mongoliensis. It is believed to be a hadrosaur or iguanodont from the Iren Dabasu Formation of Inner Mongolia, dating to 96 Ma ago. Additional specimens have been described as distinct species, including G. atavus from the Khodzhakul Formation of Uzbekistan (120 Ma ago) and G. arkhangelskyi from the Bissekty Formation (89 Ma ago).

The white-naped honeyeater (Melithreptus lunatus) is a passerine bird of the honeyeater family Meliphagidae native to eastern Australia. Birds from southwestern Australia have been shown to be a distinct species, Gilbert's honeyeater, and the eastern birds are more closely related to the black-headed honeyeater of Tasmania. One of several similar species of black-headed honeyeaters in the genus Melithreptus, it dwells in dry sclerophyll eucalypt woodland. Its diet consists of nectar from various flowers, and it also feeds on insects.
