Pseudobagrus is a genus of bagrid catfishes that inhabit streams and rivers throughout East Asia. [2] About half of these species occur in China. [3]
The two Coreobagrus species, C. brevicorpus and C. ichikiwai, are both treated in some recent literature as valid in Pseudobagrus. [4] It has been noted that Pelteobagrus may not be monophyletic if species placed in Pseudobagrus and Coreobagrus were excluded. [4] The taxonomy of this genus is unclear and many authorities treat it as a junior synonym of Tachysurus . [5]
Pseudobagrus species are small- to mid-sized bagrid catfishes. [2] These fish all have an inferior mouth; narial openings widely separated; four pairs of barbels; top of head covered by skin in most species; two dorsal fin spines; pelvic fin small; and caudal fin emarginate, truncate or round. [3]
One fossil species, P. ikiensis Watanabe & Uyeno, is known from the Middle Miocene of Japan. [1]
There are currently 32 recognized species in this genus: [6]
Acrossocheilus is a genus of ray-finned fishes in the family Cyprinidae, native to freshwater in China, Taiwan, Laos, and Vietnam. They are fairly small, no more than 30 cm (1 ft) in standard length.
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.
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.
Bagrus is a genus of bagrid catfishes. These are relatively large catfish found in freshwater habitats in Africa, except for the virtually unknown B. tucumanus from South America, which likely is a synonym of Luciopimelodus pati.
Horabagrus is a genus of catfish in the family Horabagridae endemic to rivers in the Western Ghats in Kerala and Karnataka, India. H. brachysoma is an important food fish and members of this genus can be found in the aquarium trade.
Batasio is a genus of catfish of the family Bagridae. These small fish are found in fast-flowing hillstreams throughout South and mainland Southeast Asia.
Hemibagrus is a genus of catfishes of the family Bagridae.
Mystus is a genus of fish in the family Bagridae native to Asia. Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages.
Olyra is a genus of catfishes of the family Bagridae. This genus occurs throughout South Asia and western Indochina, from India to western Thailand.
Leiocassis is a genus of bagrid catfishes found mostly in Southeast Asia with some species occurring in China.
Pseudomystus is a genus of catfishes of the family Bagridae.
Garra is a genus of fish in the family Cyprinidae. These fish are one example of the "log suckers", sucker-mouthed barbs and other cyprinids commonly kept in aquaria to keep down algae. The doctor fish of Anatolia and the Middle East belongs in this genus. The majority of the more than 140 species of garras are native to Asia, but about one-fifth of the species are from Africa.
Schistura is a genus of fish in the stone loach family Nemacheilidae native to the streams and rivers of the southern and eastern Asia. Some of these species are troglobitic.
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.
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.
Amphilius is a genus of catfishes of the family Amphiliidae.
