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, † Pseudobagrus ikiensis Watanabe & Uyeno, 1999 is known from the Middle Miocene of Japan. [6]
There are currently 32 recognized species in this genus: [7]
