Nemacheilus is a genus of stone loaches native to Asia.
The Blind cave loach is a species of troglobitic stone loach endemic to Thailand. It is only known from one subterranean stream in the Sai Yok Noi cave, which also is inhabited by Pterocryptis buccata. The blind cave loach has no eyes and lacks pigmentation. It grows to 6.8 cm (2.7 in) SL. Despite its common name, there are several other species of blind cave-living loaches.
Nemacheilus corica is a species of ray-finned fish in the genus Nemacheilus. It occurs in the foothills of the Himalayas in the drainage of the Ganges in Nepal and the Indian states of Uttar Pradesh, Uttarakhand, Bihar and West Bengal. Its reported presence in other areas need to be confirmed.
Nemacheilus anguilla, the eel loach, is a species of ray-finned fish in the genus Nemacheilus which is endemic to the Western Ghats in southern India. It occurs in streams with pebbles and with sandy substrates. It is collected for the aquarium trade but the main threat may come from pollution caused by large numbers of pilgrims which attend temples near the waters in which this species occurs.
Nemacheilus arenicolus is a species of ray-finned fish in the genus Nemacheilus which is found only in the Nam Theun and Nam Gnouang rivers in Laos.
Nemacheilus banar is a species of ray-finned fish in the genus Nemacheilus, it has currently only been recorded in Vietnam but it may occur also in Laos.
Nemacheilus binotatus is a species of ray-finned fish in the genus Nemacheilus which is found in the Chao Phraya and Maeklong basins in Thailand.
Nemacheilus cleopatra is a species of ray-finned fish in the genus Nemacheilus which is known only from the Đà Rằng River in central Vietnam.
Nemacheilus doonensis is a species of ray-finned fish in the genus Nemacheilus, although it has also been placed in the genus Schistura. from Dehra Dun in Uttar Pradesh where it occurs in clear, swift streams with pebbly beds.
Nemacheilus ornatus is a species of ray-finned fish in the genus Nemacheilus which is only known from the Tapi River basin in Thailand.
Nemacheilus papillos is a species of cyprinid fish. It occurs in Indonesia and Peninsular Malaysia. It is a demersal species that inhabits tributary and larger rivers.
Mesonoemacheilus petrubanarescui is a species of ray-finned fish from India. The specific name petrubanaescui honours the Romanian ichthyologist Petre Mihai Bănărescu. It grows to 3.5 cm (1.4 in) standard length. It is endemic to the Western Ghats and is known from only two locations, the Netravati River and Kabani River in Karnataka and Kerala. It is a little known species which is rare and may be threatened by habitat alteration, sand mining and pollution. It turns up occasionally in the aquarium trade where it is sold as the "dwarf loach".
Nemacheilus platiceps is a species of ray-finned fish in the genus Nemacheilus. It has been recorded in the lower Mekong basin in eastern Thailand, central and southern Laos, Cambodia and Vietnam. Its habitat is stretches of rivers with a gravel substrate where there is a moderate to rapid current in the lowlands and in foothills. It is consumed locally in subsistence fisheries and is occasionally found in the aquarium trade.
Nemacheilus ruppelli, also known as the mongoose loach is a species of fish in the genus Nemacheilus. This fish is endemic to the Western Ghats of India. Recent evidence shows that there is only a marginal raw mitochondrial genetic distance between Nemachilichthys shimogensis and N. ruppelli. Although morphometric difference occur at the population level, Keskar et al. conclude that there are no significant differences separating the two species. Therefore they treat N. shimogensis as a synonym of N. ruppelli. The Eschmeyer's Catalog of Fishes follows this treatment.
Nemacheilus singhi is a species of ray-finned fish in the stone loach genus Nemacheilus, although some authorities place it in the genus Schistura. This species has only been recorded from a single locality in Nagaland, India.
Nemacheilus stigmofasciatus, the Thuttinjet stone loach, is a species of ray-finned fish in the genus Nemacheilus which has been recorded from just one locality in the west flowing river Seethanathi at Thuttinjet in Karnataka. This locality is at an altitude of 199m above sea level and has many cascades and waterfalls in its upstream portion. The stream is dominated by the presence of pebbles and boulders with gravel and sand making up approximately 5% of the substrate.
Nemacheilus subfusca is a species of ray-finned fish from the family Nemacheilidae in the genus Nemacheilus which is found in Assam and China. It inhabits pebbly streams. N. subfusca was synonymised with Neomacheilus scaturigina which was described by Menon from the collection of Hamilton. It was, however, then treated as a valid species and sometimes placed in the genus Schistura.
Nemacheilus tuberigum is a species of stone loach endemic to Sumatra, Indonesia. It grows to 4.8 cm (1.9 in) SL.
Triplophysa kullmanni is a species of ray-finned fish in the genus Triplophysa. It is endemic to Afghanistan.
Nemachilichthys shimogensis, the Shimoga loach, is a species of stone loach from the Western Ghats of Maharashtra and Karnataka. Although Fishbase treats it as a valid species some authorities state that N. shimogensis is the same species as, i.e. a synonym of, Nemacheilus rueppelli, which they then place as the only species in the genus Nemachilichthys.
