Rectoris is a genus of cyprinid fish found in China and Vietnam.
China, officially the People's Republic of China (PRC), is a country in East Asia and the world's most populous country, with a population of around 1.404 billion. Covering approximately 9,600,000 square kilometers (3,700,000 sq mi), it is the third- or fourth-largest country by total area. Governed by the Communist Party of China, the state exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities, and the special administrative regions of Hong Kong and Macau.
Vietnam, officially the Socialist Republic of Vietnam, is the easternmost country on the Indochina Peninsula. With an estimated 94.6 million inhabitants as of 2016, it is the 15th most populous country in the world. Vietnam is bordered by China to the north, Laos and Cambodia to the west, part of Thailand to the southwest, and the Philippines, Malaysia, and Indonesia across the South China Sea to the east and southeast. Its capital city has been Hanoi since the reunification of North and South Vietnam in 1976, while its most populous city is Ho Chi Minh City.
There are currently five recognized species in this genus: [1] [2]
Aspidistra is a genus of flowering plants in the family Asparagaceae, subfamily Nolinoideae, native to eastern and southeastern Asia, particularly China and Vietnam. They grow in shade under trees and shrubs. Their leaves arise more or less directly from ground level, where their flowers also appear. The number of species known has increased considerably from the 1980s onwards, with around 100 accepted as of July 2013. Aspidistra elatior is common worldwide as a foliage house plant that is very tolerant of neglect. It and other species can also be grown in shade outside, where they are generally hardy to −5 °C (23 °F).
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.
Schizothorax is a genus of cyprinid fish from Central and East Asia. Their scientific name means "cloven-breast", from Ancient Greek schízeïn (σχίζειν) "to cleave" and thórax (θώραξ) "breast-plate". The western species are typically referred to as marinkas from their Russian name marinka (маринка), while the eastern species are usually called snowtrout. But though they do resemble trouts in habitus this is merely due to convergent evolution and they are by no means closely related apart from both being Teleostei: Cyprinids are in the teleost superorder Ostariophysi, while trouts are in the superorder Protacanthopterygii. Their ancestors must thus have diverged as early as the Triassic, more than 200 million years ago.
Sinocyclocheilus is a genus of freshwater fish in the family Cyprinidae endemic to China, where only found in Guangxi, Guizhou and Yunnan. 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.
Oreonectes is a genus of fish in the family Nemacheilidae found in the rivers and cave of Asia. Many of these species are troglobitic.
Poropuntius is a genus of cyprinid fish found mainly in freshwater habitats of Southeast Asia and Yunnan in China, but P. burtoni is from South Asia. Several species have highly restricted ranges and are threatened, and a single P. speleops is a cavefish.
Protocobitis is a genus of loaches endemic to Guangxi in China and living in caves.
Schistura is a genus of fish in the stone loach family Nemacheilidae native to the streams and rivers of the southern and eastern Asia. Some of these species are troglobitic.
Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China. 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 these have been treated as subgenera in Wikipedia, although Kottelat and the Catalog of Fishes treat them as genera. FishBase, however, includes these in Triplophysa without specifying subgenera and treats the names given by Kottelat as synonyms.
Yunnanilus is a genus of small stone loaches that are endemic to southeastern China, especially Guangxi and Yunnan. They are found in rivers, streams and lakes; some species are restricted to caves.
Barbastella is a small genus of vespertilionid bats. There are five described species in this genus.
Siniperca is a genus of temperate perches native to freshwater habitats in East Asia and northern Vietnam, but the majority of the species are entirely or largely restricted to China.
Heminoemacheilus is a small genus of stone loaches endemic to Guangxi in China and only living in caves.
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
Ptychidio is a genus of cyprinid fish endemic to China.
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.
