[[ Genus Pseudobagrus ZBK ]]
All species of the bagrid catfish genus Pseudobagrus Bleeker ZBK , 1859 share the following features: an inferior mouth; narial openings widely separated; four pairs of barbels; top of head covered by skin, except the posterior process of supraoccipital in some species; two dorsal spines; pelvic fin small; caudal fin emarginate, truncate or round. Currently 15 nominal species of Pseudobagrus ZBK are recognised in China (Zheng and Dai, 1999), accounting for about half of the worlds species in the genus (see Ng, 2003). However, relatively little work has been done on bagrid catfishes (Ng, 2003), members of Pseudobagrus ZBK are morphologically similar, and diagnostic characters are usually subtle.
