Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 2; Mjukstrålar i ryggfenan (totalt): 7; Mjukstrålar i analfenan: 17 - 21; Ryggkotor: 47 - 48. Closely resembles Pseudobagrus adiposalis and P. ussuriensis, but differs in having a large elliptical eye (19.8-24.4% HL), a short maxillary barbel not reaching the posterior margin of the eye, a lightly serrated posterior edge on the second dorsal spine, a caudal fin slightly emarginate with upper lobe slightly longer than lower lobe, frontal concave with a smooth surface, and supraoccipital process short (far from the first basal bone of the dorsal spine) (Ref. 56712).
Inhabits medium to large rivers in lowland areas with rocky substrate and moderate or far current (Ref. 56712).
