Cobitidae, also known as the true loaches, is a family of Old World freshwater fish. They occur throughout Eurasia and in Morocco, and inhabit riverine ecosystems. Today, most "loaches" are placed in other families. The family includes about 260 described species. New species are being described regularly.
Acantopsis is a genus of freshwater fishes, commonly known as horseface loaches or banana-root fishes, in the family Cobitidae. Fishes of the genus Acantopsis inhabit sandy riverbeds throughout Southeast Asia and are most diverse in the Mekong River in Thailand, Laos, and Cambodia wherein five species are known to occur. The common horseface loach, A. rungthipae, is popular in the aquarium trade.
Acanthocobitis is a genus of freshwater ray-finned fish of the stone loach family, Nemacheilidae. Recent work has suggested that the genus be split into two with the former subgenus Paracanthocobitis being raised to a full species, leaving just the type species, Acanthocobitis pavonacea, in the current genus.
Lepidocephalichthys is a genus of ray-finned fish in the family Cobitidae.
Nemacheilus is a genus of stone loaches native to Asia.
Botiidae, the pointface loaches, is a family of cypriniform ray-finned fishes from South, Southeast, and East Asia. Until recently they were placed in the true loach family Cobitidae, until Maurice Kottelat revised the loaches and re-elevated this taxon to family rank in 2012. The family includes about 56 species.
Micronemacheilus pulcherrimus is a species of ray-finned fish, a stone loach, in the genus Micronemacheilus. 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.
Acanthocobitis pavonacea, also known as the spearfin loach, is a species of ray-finned fish belonging to the family Nemacheilidae, the stone loaches. This species is found in the Brahmaputra River ofAssam. This is one of two species in the genus Acanthocobitis, alongside the type species, A. longipinnis. A. longipennis was treated as synonym of this species but in 2021 Maurice Kottelat and Waikhom Vishwanath published a paper that argued that A. longipennis was a valid species and that it was one of two species ofloach in the genus Acanthocobitis, alongside A. pavonacea, with the other species being classified in the genus Paracanthocobitis. This species is the type species of the genus Acanthocobitis.
Balitora is a genus of ray-finned fishes in the family Balitoridae endemic to Asia.
Homaloptera is a genus of ray-finned fish in the family Balitoridae.
Afronemacheilus is a genus of freshwater ray-finned fish of belonging to the family, Nemacheilidae, the stone loaches. The fishes in this genus are endemic to Ethiopia.
Homatula is a genus of stone loaches endemic to China.
Nemachilichthys is a monospecific genus of freshwater ray-finned fish belonging to the family Nemacheilidae, the stone loaches. The only species in the genus is Nemachilichthys rueppelli, the mongoose loach or Shimoga loach, a species endemic to the Western Ghats in Karnataka and Maharashtra.
Physoschistura is a genus of fish in the family Nemacheilidae found mostly in Southeast Asia.
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.
Petruichthys is a genus of stone loaches native to eastern Asia. The genus is not universally accepted as valid and the two species placed there have been placed in other genera.
Tarimichthys is a subgenus of stone loach genus Triplophysa native to China which contains two species. Some authorities recognise Tarimichthys as a valid taxon.
Acanthocobitis longipinnis is a species of freshwater ray-finned fish belonging to the family Nemacheilidae, the stone loaches. This species is known from a single specimen, the holotype, which was collected from the Ganges. This species was first formally described in 1861 by the German naturalist and explorer Wilhelm Peters and Peters proposed the new genus Acanthocobitis. Later authors treated this species as a synonym of Cobitis pavonacea but in 2021 Maurice Kottelat and Waikhom Vishwanath published a paper that argued that A. longipennis was a valid species and that it was one of two species of loach in the genus Acanthocobitis, alongside A. pavonacea, with the other species being classified in the genus Paracanthocobitis. This species is the type species of the genus Acanthocobitis.
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.
Malihkaia is a monospecific genus of freshwater ray-finned fish belonging to the family Nemacheilidae, the stone loaches. The only species in the genus is Malihkaia aligera. This species was foirsy formalled described in 2017 by the Swiss ichthyologist Maurice Kottelat with its type locality given as the Mali Hka River, about 9 km upstream of Kang Mu Lon on the Kachin State of Myanmar at 27°25'54"N, 97°27'56"E from an elevation of 402 m (1,319 ft).
