IdentificationCatfish of the genus Pseudobagarius are akysids with the snout extending well in front of the tip of lower jaw (which renders the mouth subterminal). The front and back nostrils are relatively large and closely set (separated only by the base of the nasal barbel). The caudal fin is deeply forked.

Can be differentiated from its congeners in the following characters: lacking distinct serrae on posterior edge of pectoral spine; adipose fin with moderately long base, its length 13.4-16.7 %SL; eye diameter 7-10 %HL; length of nasal barbel 38-57 %HL; tip of snout noticeably in front of apex of lower jaw; large anterior and posterior nostrils present, closely situated together and separated only by base of nasal barbel; caudal fin with 7+7-8 rays; branchiostegal rays 6-7; a light yellow snout with a sharp contrasted edge; color pattern consisting of dorsal and ventral light yellow patches on the body that sometimes coalesce at mid-height of the flank.
