Rectoris is a genus of cyprinid fish found in China and Vietnam.
There are currently five recognized species in this genus: [1] [2]
Acrossocheilus is a genus of ray-finned fishes in the family Cyprinidae, native to freshwater in China, Taiwan, Laos, and Vietnam. They are fairly small, no more than 30 cm (1 ft) in standard length.
Sinocyclocheilus is a genus of freshwater fish in the family Cyprinidae that is endemic to Guangxi, Guizhou and Yunnan in China. Almost all of its species live in or around caves and most of these have adaptions typical of cavefish such as a lack of scales, lack of pigmentation and reduced eyes. Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back, the function of which is unclear. In contrast, the Sinocyclocheilus species that live aboveground, as well as a few found underground, show no clear cavefish adaptions. They are relatively small fish reaching up to 23 cm (9.1 in) in length. The individual species have small ranges and populations, leading to the status of most of the evaluated species as threatened. Many species populations in the genus have yet to be evaluated by the IUCN.
Protocobitis is a genus of loaches endemic to Guangxi in China and living in caves.
Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China, as well as inland waters of the larger part of central Asia. They can be distinguished from other genera of Nemacheilidae by marked sexual dimorphism, including the development of nuptial tubercles on breeding males. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera, but as Wikipedia follows Fishbase for fish species all but Hedinichthys have been treated as subgenera in Wikipedia, although Kottelat in his revision of the loaches did recognise them as valid. FishBase, however, includes these in Triplophysa without specifying subgenera and treats the names given by Kottelat as synonyms.
Sillago is a genus of fish in the family Sillaginidae and the only non-monotypic genus in the family. Distinguishing the species can be difficult, with many similar in appearance and colour, forcing the use of swim bladder morphology as a definitive feature. All species are benthic in nature and generally coastal fish, living in shallow, protected waters although there are exceptions. Minor fisheries exist around various species of Sillago, making them of minor importance in most of their range. This genus has the widest distribution of any smelt-whiting genus, spanning much of the Indo-Pacific. The genus ranges from the east coast of Africa to Japan in the east and Southern Australia in the south, with most species concentrated around South East Asia, the Indonesian Archipelago and Australia. Many species have overlapping distribution, often making positive identification hard.
Barbastella is a genus of vespertilionid bats. There are seven extant species in this genus and one only known from fossil remains.
Siniperca or the Chinese perch is a genus of centrarchiform ray-finned fish native to freshwater habitats in continental East Asia. Although its native ranges can extend to northern Vietnam, the majority of the species are entirely or largely restricted to China.
Paranemachilus is a genus of stone loaches endemic to China.
Parabotia is a genus of loaches. Most species in the genus are endemic to China, but P. curtis is from Japan, P. dubius is from Vietnam, and P. mantschuricus is from the Amur River basin.
Aphyocypris is a genus of cyprinid fishes consisting of eight species, all of which are restricted to East Asia.
Discogobio is a genus of cyprinid fish that are found in eastern Asia. So far the 16 species have only been identified from China and Vietnam wherein each species is endemic to the country in which it is found.
Parasinilabeo is a genus of cyprinid fish endemic to China. There are currently six described species in this genus.
The Nemacheilidae, or stone loaches, are a family of cypriniform fishes that inhabit stream environments, mostly in Eurasia, with one genus, Afronemacheilus found in Africa. The family includes about 790 species.
The Beijing barbastelle, also known as the Beijing wide-eared bat, is a species of vesper bat endemic to Beijing Municipality, China. The species was discovered by Chinese zoology students in 2001 in caves of Fangshan District in southwestern Beijing and was identified as a distinct species by zoologists Zhang Shuyi, Gareth Jones, Zhang Jingshuo and Han Naijian in 2007.
Troglonectes is a genus of troglobitic fish in the family Nemacheilidae, native to caves of Asia. Fishbase and other authorities place these species in the genus Oreonectes.
Rectoris longifinus is a species of freshwater ray-finned fish belonging to the family Cyprinidae, the family which includes the carps, barbs. minnows and related fishes. This species is endemic to Yunnan in China. This species was fisrt formally described) in 2002 from Zhoxi in Shilin County and said to be similar to R. posehensis, however, other authors consider that this species is unlikely to be a member of the genus Rectoris and that it is generic placement awaits further study.
Rectoris luxiensis is a species of freshwater ray-finned fish belonging to the family Cyprinidae, the family which includes the carps, barbs. minnows and related fishes. This species is endemic to China where it is found in the Yuan Jiang in Hunan, Qing Jiang in Hubei Province) and the Daninghe River in Sichuan. One study found that there were no discernible differences between the specimens of this species and the types of R. mutabilis suggested that R. mutabilis is s senior synonym of R, luxiensis. Eschmeyer's Catalog of Fishes, however, recognises both these taxa as valid species.
Rectoris mutabilis is a species of freshwater ray-finned fish belonging to the family Cyprinidae, the family which includes the carps, barbs. minnows and related fishes. This species is endemic to Yunnan in China. This species is endemic to China in the drainage basin of the Yangtze in Guizhou, Hunan, Chongqing and Hubei. One study found that there were no discernible differences between the specimens of this species and R. luxiensis suggested that R. mutabilis is s senior synonym of R, luxiensis. Eschmeyer's Catalog of Fishes, however, recognises both these taxa as valid species.
This list of fossil fish research presented in 2022 is a list of new fossil taxa of jawless vertebrates, placoderms, cartilaginous fishes, bony fishes, and other fishes that were described during the year, as well as other significant discoveries and events related to paleoichthyology that occurred in 2022.
Karstinnectes is a genus of freshwater ray-finned fishes belonging to the family Nemacheilidae, the stone loaches. The fishes in this genus are cavefish found in China.
