Etymology

The specific name anshuiensis is due to the type locality of the species, village Anshui located closer to Xijiang River, China. [1]

Lateral line is complete. Elongated body is slightly compressed anteriorly and strongly compressed posteriorly. Thick lips have shallow furrows. Three pairs of barbels are present. Dorsal and anal fins are truncate. Pectoral fins are slightly developed. Caudal fin forked and tips are pointed. [1]

Ayumodoki Species of fish

The Ayumodoki or Kissing Loach is a species of ray-finned fish in the family Botiidae. It is found in lakes and streams on Honshu, the largest island of Japan. Spawning grounds for kissing loach are ditches and small reservoirs for rice cultivation of a river system located in Japan. The kissing loach migrates to flooded areas, including paddy field areas, for spawning in early summer and the spawning of this species is limited after the formation of flooded areas over terrestrial vegetation. These flooded areas are the result of water from mountain streams and irrigation ponds flooding once dry land which create creating man-made wetlands. As, adults, Parabotia curtus migrate from these flooded paddy fields to fast moving, muddy streams and rivers like the Yodo River.

Stone loach Species of fish

The stone loach is a European species of fresh water ray-finned fish in the family Nemacheilidae. It is one of nineteen species in the genus Barbatula. Stone loaches live amongst the gravel and stones of fast flowing water where they can search for food. The most distinctive feature of this small fish is the presence of barbels around the bottom jaw, which they use to detect their invertebrate prey. The body is a mixture of brown, green and yellow.

<i>Triplophysa</i> Genus of fishes

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 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.

Yunnanilus macrogaster is a hypogean species of stone loach endemic to China. This species is endemic to the endorheic drainage system which feeds the Datangzi Marsh in Luoping County, Yunnan, the marsh has been formed by the outflow of a stream from its underground course. It is a demersal species and the waters where it was found were densely vegetated, it feeds on worms and insects. It is sympatric with Yunnanilus niger and Y, paludosus, forming a small species flock. It lays eggs which is does not guard.

Yunnanilus pulcherrimus is a species of ray-finned fish, a stone loach, in the genus Yunnanilus. It is found in the Hongshuihe River, part of the Xijiang River basin in China, with the type locality in Du'an County, Guangxi. The specific name pulcherrimus means most beautiful and is a reference to the “unique” banded color pattern ofthin vertical stripes crossing a wide lateral band, when compared to related species.

<i>Triplophysa bleekeri</i> Species of fish

Triplophysa bleekeri is a species of stone loach in the genus Triplophysa. It is endemic to China. It grows to 8.2 cm (3.2 in) TL. Having a wide distribution across the Qinghai-Tibet Plateau, it lives in fast-flowing rivers from 200 to 3,000m in altitude. Being an unusual species inhabiting high-altitude regions, it is an excellent model to investigate the genetic mechanisms of adaptation to the local environment. With this in mind a chromosomal-scale genome assembly was sequenced and assembled with a genome size of ∼628 Mb. This data finding that the Triplophysa genus likely diverged when the Qinghai-Tibet Plateau elevated by >4,000 m roughly 40 million years ago.
