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. [1] 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. [2] They are found in Asia Minor (in the Tigris and Euphrates River drainages) and southwards to Southeast Asia. The genus is very diverse in the Indian subcontinent. [3] Southeast Asian species tend to have restricted distributions. [4]

Description

This genus is easily distinguished from other sisorids by having an adhesive apparatus on the thorax with grooves parallel or oblique to the longitudinal axis of the body, as opposed to grooves transverse to the longitudinal axis of body or the thoracic adhesive apparatus entirely absent. [2] The dorsal fin and pectoral fins have strong spines. The dorsal fin spine is smooth or serrate on the front edge and smooth or finely serrated on the posterior edge. The pectoral fin spine is serrated on the front edge. The head is small and depressed and the snout is conical. The body is elongate, from moderately to greatly depressed. The skin is either smooth or tuberculate. The eyes are small and dorsally placed. The lips are thick, fleshy and often papillate. The maxillary barbels have a well-developed membrane and a soft base. The gill openings are wide. The paired fins are plaited and modified to form an adhesive apparatus in some species of Glyptothorax. [2]

Ecology

Like other sisorids, these fish are rheophilic, that is they inhabit fast-flowing streams, where they are adapted to live by using the adhesive apparatus on the underside to attach themselves to rocks and prevent being washed away. [4]

Species

There are currently 110 recognized species in this genus: [1]

<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.

<i>Oreoglanis</i> Genus of fishes

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.

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.

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.

<i>Psilorhynchus</i> Genus of fishes

Psilorhynchus is a genus of fish in the family Psilorhynchidae native to South Asia. This genus is the only member of its family. The members of Psilorhynchus are small benthic fishes which occur in rivers and streams with fast to swift currents, hence they are often referred to a torrent minnows. They are distributed in southern Asia, in the Indo-Burma region and the Western Ghats.
