Schistura papulifera | |
Schistura papulifera is a critically endangered species of ray-finned fish, a troblobitic stone loach, in the genus Schistura endemic to the state of Meghalaya in India. It is currently known to be restricted to the Krem Synrang Pamiang cave system near the Jaintia Hills, where it is threatened by limestone extraction. This species lives in pools of standing water within the cave system preferring these to the streams of flowing water, being most numerous in the largest and deepest pools. This may be because the larger pools offer a more stable environment for the fish. [1] The specific name is a compound of the Latin papula meaning "a small tumour" and fera meaning "to bear", referring to the growths around the lower half this species head. [3]
Schistura oedipus is a species of troglobitic stone loach endemic to caves in the Pang Mapha karst formation in Mae Hongson Province in Thailand. It is only found in very fast flowing cave streams where it feeds on micro-organism and organic matter. This species is highly sensitive to disturbance, changes in water quality and hydrography. The specific name oedipus refers to the mythical Ancient Greek king of Thebes, Oedipus who tore out his own eyes, this species has degenerate eyes.
Schistura sijuensis is a troglobitic species of stone loach endemic to India.
Schistura deansmarti is a species of ray-finned fish in the stone loach genus Schistura. It is found in cave streams in a karst landscape in the Thung Salaeng Luang National Park of Phitsanulok Province where it lives mainly on the stream beds and feeds on organic material and micro-organisms. The specific name honors the British speleologist who collected the original specimens and who works for the conservation of caves in Thailand.
Schistura geisleri is a species of ray-finned fish in the genus Schistura, the most speciose of the genera within the stone loach family, Nemacheilidae. Its known range is in the upper parts of the Chao Praya in Thailand but it has also been reported from the Tapi River in Peninsular Thailand, as it has not been recorded from the darainages between these two systems the taxonomic status of the Tapi population may need to be reassessed. Its habitat is slow flowing streams with depths no greater than 30 cm during the dry season and in shallow riffles with a substrate consisting of pebbles which are up to 5 cm in diameter, with a moderate current and clear water. The specific name honours the German aquarist Rolf Geisler (1925-2012), in thanks for his "valuable help".
Schistura kangjupkhulensis is a species of ray-finned fish in the most speciose genus of stone loaches, Schistura. It can be found in shallow, fast flowing streams with gravel substrates in the Tizu, Imphal and Nambul Rivers on the Chindwin Basin in Manipur, India. This species is very rare and appears to be decreasing and its populations are threatened by destructive fishing emtods as well as human alteration of its habitat by damming and water abstraction.
Schistura kaysonei, the Laotian cave loach, is a species of ray-finned fish in the genus Schistura. It is endemic to Laos where only found in streams in caves. Like other cave-adapted fish, it is blind and has little pigmentation. This troglobitic species has been recorded from only a single cave in a karst landscape in Khammouane Province in Laos. Here it can be found around 100m from the cave entrance and its diet is thought to be organic detritus, such as bat guano, and micro-organisms. It is threatened by a decline in the quality and quantity of the water flowing through the case, caused by deforestation and increased agriculture, as well as potential overfishing for the aquarium trade. The specific name honours Kaysone Phomvihane (1920-1992), who was president of Laos.
Schistura khugae is a species of ray-finned fish in the stone loach genus Schistura. It lives on the bottom of hill streams in the Khuga River, part of the Chindwin River system in Manipur, India.
Schistura malaisei is a species of ray-finned fish, a stone loach, in the genus Schistura. It is a benthic species of fast-flow, well-oxygenated, cool water in the Irrawaddy River basin of Myanmar and Yunnan. It can be found in the aquarium trade and over exploitation may threaten local populations. The specific name honours Swedish entomologist René Malaise (1892-1978), who collected type and in whose fish collections from Burma (1933-1935), including specimens from some remote localities, Maurice Kottelat found the type specimen from which he described the species.
Schistura obeini is a species of ray-finned fish, a stone loach, in the genus Schistura. It has been recorded from the Nam Theun and Nam Gnouang rivers in Laos where it inhabits fast or very fast flowing water over pebble or stone beds in the headwaters of the rivers. The specific name honours François Obein of the Nam Theun 2 Electricity Consortium in Vientiane for the assistance he gave to the describer Maurice Kottelat in the field and for his organisation of logistics in the field.
Schistura paucifasciata is a species of ray-finned fish, a stone loach, in the genus Schistura. This species is known only from Hwe-gna-sang River in the Hsipaw State, in the northern Shan States of Myanmar and has not been recorded since the type was collected. It is a benthic species which is found in hill streams with cool, flowing water.
Schistura poculi is a species of ray-finned fish, a stone loach, in the genus Schistura. This species of stone loach is currently thought to occur in the basins of the Mekong, Salween and Chao Praya rivers in Myanmar, Thailand and Laos. However, these may refer to more than one species, in which case the name S. poculi belongs to the population in the Chao Praya. It can be found in streams with moderately fast to fast currents among riffles where there are substrates which vary from gravel to stone. The specific name poculi means "bowl" and refers to the type locality, Doi Angkon in Thailand with angkon meaning "crow's bowl".
Schistura prashadi is a species of ray-finned fish, a stone loach, in the genus Schistura. Some authorities place it in the genus Physoschistura It is known from just three localities in the Chindwin River drainage in Manipur, India. It is a benthic species of hill streams, preferring well oxygenated, clear, flowing water.
Schistura reticulata is a species of ray-finned fish, a stone loach in the genus Schistura. It is found in three hill streams in the Chindwin drainage basin on Manipur. In some areas, such as the Lokchao River at Moreh the populations of this species are severely threatened by development and border trade while in other areas it is threatened by destructive fishing techniques using poison and explosives.
Schistura rupecula is a species of ray-finned fish, a stone loach, in the genus Schistura. It is distributed through the eastern Himalayas from North Bengal through Bihar, Himachal Pradesh, Uttaranchal and Uttar Pradesh in India and into Nepal. Its habitat is hill streams with pebbly stream beds while adults are often found in shallow water riffles and spring pools. The specific name rupecula means "rock dweller" which was given to the species by its describer John McClelland in reference to the hill streams around Simla from where the type specimens were collected. It is the type species of the genus Schistura.

It has only been found to occur in the Mong Mo river, a small coastal drainage, in central Vietnam. The specific name honors Susanne Klähr, for the help she gave to Maurice Kottelat in his field work.
