Pseudobagrus aurantiacus (Temminck and Schlegel) by Kawahara Keiga, 1823 - 1829.

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]

Species[edit]

There are currently 32 recognized species in this genus:[6]
