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.

Distinguished from all its congeners by possessing tubercles with poorly-demarcated, indistinct margins (versus tubercles with well-demarcated and distinct margins) and the following combination of characters: head width 20.3-25.0% SL; body depth at anus 11.3-14.7% SL; depth of caudal peduncle 5.7-7.3% SL; pectoral-fin length 23.1-28.9% SL; interorbital distance 34-39% HL; eye diameter 7-11% HL; length of nasal barbel 29-65% HL; length of maxillary barbel 122-144% HL; length of outer mandibular barbel 88-134% HL; color pattern of dark-colored patches on a predominantly light-colored body (versus predominantly dark-colored body with light-colored patches in its congeners).
