Amblyceps carinatum is a species of catfish belonging to the family Amblycipitidae. It is only known from the upper part of the Irrawaddy River basin in Myanmar. [1] [2]

This is a small catfish (up to 36 mm standard length) found in fast flowing streams. The main characteristic which distinguishes it from its congeners is the shape of the adipose fin: in A. carinatum it takes the form of a long low ridge starting just behind the dorsal fin whilst in all other Amblyceps species it is blade-shaped and starts well behind the dorsal fin.

Amblycipitidae Family of fishes

The Amblycipitidae are a family of catfishes, commonly known as torrent catfishes. It includes three genera, Amblyceps, Liobagrus, and Xiurenbagrus, and about 36 species.

<i>Pseudolaguvia</i> Genus of fishes

Pseudolaguvia is a genus of South Asian river catfishes. These species inhabit hill streams and large rivers. P. tenebricosa is found in fast running, clear water; the river has a sandy bottom and numerous rocks and boulders and aquatic vegetation is absent. P. inornata is from clear, shallow, moderately flowing streams with a predominantly sandy bottom. P. muricata is found in clear, shallow, slow-flowing streams with a mixed substrate of sand and detritus; these fish are found amongst detritus in areas with current. P. ferula is also found in swift flowing waters with a mixed rocky/sandy bottom.

Pseudolaguvia tenebricosa is a species of catfish. It is only known from a fast-flowing hill stream called Pathe Chaung, near Taungoo in southern Burma.

Kryptopterus geminus is a species of catfish belonging to the family Siluridae. It can be distinguished from all its congeners, with the exception of Kryptopterus cryptopterus, by the almost flat dorsal profile with no concavity behind the head. This species grows to a length of 17.1 centimetres (6.7 in) SL.

<i>Clarias batu</i> Species of fish

Clarias batu is a species of clariid catfish. It is only known from Tioman Island off the eastern coast of Peninsular Malaysia. The eel-like catfish found on this island were originally identified as the widespread species Clarias nieuhofii but comparison of a large series of specimens from Tioman with a series of C. nieuhofii from the mainland revealed consistent and distinctive differences indicating a separate species.

Amblyceps is a genus of fish in the family Amblycipitidae. The genera Amblyceps and Liobagrus are sister group pair that is, in turn, sister to Xiurenbagrus. These species are easily distinguished by the presence of pinnate processes along with the median caudal-fin rays, a prominent cup-like skin flap above the base of the pectoral spine ,and the adipose fin largely separate from the caudal fin. In most species the caudal fin is deeply forked; A. apangi and A. murraystuarti differ in having their caudal fin truncate. Amblyceps species may reach about 100 millimetres (3.94 in) SL.

<i>Liobagrus</i> Genus of fishes

Liobagrus is a genus of catfishes of the family Amblycipitidae. Liobagrus fishes are distributed in the Yangtze River basin, Taiwan, Japan, and the Korea Peninsula. The adipose fin of these fishes is a confluent with the caudal fin. The nostrils are far apart, unlike those found in Amblyceps. Most Liobagrus species grow to about 100 millimetres (3.94 in) SL.

Exostoma is a genus of sisorid catfishes native to Asia. These species are distributed in the Brahmaputra drainage of northeast India, and east and south to the Salween drainages in Burma. E. berdmorei is found in the Sittang and Salween drainages in Burma. E. labiatum is known from the Brahmaputra drainage in northeast India, but has also been recorded in the Salween drainage in Burma, the Ayeyarwady drainage in China, and the Brahmaputra drainage in Tibet and Burma. E. stuarti is from the Ayeyarwady River of Burma and India; however, it has not been collected since its original discovery. E. labiatum is found in mountain rapids.

Liobagrus aequilabris is a species of catfish in the family Amblycipitidae. This species is endemic to China, where it is only known from the Xiang River, a tributary of the Yangtze River, in Guangxi province, but may also be present in the Li River, a tributary of the Pearl River, due to the presence of the Lingqu Canal connecting the Xiang and Li Rivers.

Liobagrus somjinensis is a species of catfish in the family Amblycipitidae. It is known from the western and southern coasts of Korea and Geogeum Island, where it has been found in rivers and tributaries. L. somjinensis can be distinguished physically from other torrent catfish by the unusual length of its dorsal spine and outer mental barbel and the shortness of the distance from its dorsal-fin insertion point to its adipose-fin point of origin, as well as by markings and coloration on the fins. The caudal fin displays a broad vertical band in its center, yellow in hue and shaped like a crescent, while the dorsal, anal, and caudal fins have deep black colour on their outer margins. It grows to 10.1 cm (4.0 in) standard length.

Liobagrus marginatoides is a species of catfish in the family Amblycipitidae endemic to the province of Sichuan in China. This species reaches a length of 8.5 centimetres (3.3 in) SL.
