Pseudobagrus gracilis Li, Chen & Chan 2005

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).

Dorsal spines (total): 2; Dorsal soft rays (total): 7; Analsoft rays: 17 - 21; Vertebrae: 47 - 48

Inhabits medium to large rivers in lowland areas with rocky substrate and moderate or far current (Ref. 56712).
