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. [1] 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. [2]
No shared derived characteristic has been found to diagnose the genus Liobagrus. [2] However, it is maintained that this genus is currently monophyletic. Liobagrus has been placed in the family Bagridae. Later, it was found to more closely resemble Amblyceps , and was transferred to Amblycipitidae. [2]
Xiurenbagrus was erected because Liobagrus would not be monophyletic with Liobagrus xiurenensis, now Xiurenbagrus xiurenensis. The genera Amblyceps and Liobagrus are sister group pair that is, in turn, sister to Xiurenbagrus. [2]
There are currently 15 recognized species in this genus:
Hypostomus is a genus of catfish in the family Loricariidae. They are native to tropical and subtropical South America. H. plecostomus is the popular freshwater aquarium fish formerly known as Plecostomus plecostomus. The taxonomic structure of the Loricariidae is still being expanded by scientists. Hypostomus is a highly species-rich and widely distributed catfish genus.
The Amblycipitidae are a family of catfishes, commonly known as torrent catfishes. It includes three genera, Amblyceps, Liobagrus, and Xiurenbagrus, and about 36 species.
Clarias is a genus of catfishes of the family Clariidae, the airbreathing catfishes. The name is derived from the Greek chlaros, which means lively, in reference to the ability of the fish to live for a long time out of water.
The Bagridae are a family of catfish that are native to Africa (Bagrus) and Asia from Japan to Borneo. It includes about 245 species. These fish are commonly known as naked catfishes or bagrid catfishes.
Sisoridae is a family of catfishes. These Asian catfishes live in fast-moving waters and often have adaptations that allow them to adhere to objects in their habitats. The family includes about 235 species.
Oreoglanis is a genus of fish in the family Sisoridae native to Asia. These fish live in fast-flowing streams in China, mainland Southeast Asia and the Indian subcontinent. They are mainly distributed in the Mekong, upper Salween and Irrawaddy River drainages. They range from the Brahmaputra basin to the Lam River drainage in central Vietnam. They are easily distinguished from other catfishes by their strongly depressed head and body and greatly enlarged paired fins that have been modified to form an adhesive apparatus. The flattened shape of these fish and the large pectoral and pelvic fins provide essential adhesion in the fast-flowing waters they live in.
Glyptothorax is a genus of catfishes order Siluriformes of the family Sisoridae. It is the most species-rich and widely distributed genus in the family with new species being discovered on a regular basis. These species are distributed in the Black Sea basin, northern Turkey, south and east to the Yangtze River drainage in China and south throughout Indo-China to Java, Indonesia. They are found in Asia Minor and southwards to Southeast Asia. The genus is very diverse in the Indian subcontinent. Southeast Asian species tend to have restricted distributions.
The Hypoptopomatinae are a subfamily of catfishes of the family Loricariidae, composed of 17 genera and approximately 80 species. This subfamily represents about one-tenth of all loricariid species.
Pseudobagrus is a genus of bagrid catfishes that inhabit streams and rivers throughout East Asia. About half of these species occur in China.
Pseudomystus is a genus of catfishes of the family Bagridae.
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.
Xiurenbagrus is a genus of torrent catfishes of the family Amblycipitidae. It includes three species.
Exostoma is a genus of sisorid catfishes native to Asia. These species are distributed in the Brahmaputra drainage of north-eastern 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 north-eastern 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.
Pareuchiloglanis is a genus of sisorid catfishes native to Asia. These species are rheophilic catfish chiefly found in the headwaters of major rivers in South and East Asia. They originate from the Brahmaputra drainage in India, east and south to the Yangtze drainage in China and the Annamese Cordillera drainages in southern Vietnam. Two species are known from the Mekong River: P. myzostoma and P. gracilicaudata. Four species are known from the drainage of China: P. abbreviatus, P. gracilicaudata, P. myzostoma and P. prolixdorsalis.
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 chenghaiensis is a species of catfish in the family Amblycipitidae endemic to China, where it is only known from lake Chenghai in the province of Yunnan.
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 styani is a species of catfish in the family Amblycipitidae endemic to the province of Hubei in China. This species reaches a length of 12 centimetres (4.7 in) TL.
Liobagrus hyeongsanensis is a species of catfish in the family Amblycipitidae endemic to South Korea.
