Can be differentiated further from all congeners except Pseudomystus breviceps, Pseudomystus bomboides, Pseudomystus flavipinnis, Pseudomystus myersi, Pseudomystus siamensis, Pseudomystus robustus, Pseudomystus sobrinus and Pseudomystus stenomus in having a deeper body (17.8-21.0% SL vs. 9.0-17.0). Differs from Pseudomystus leiacanthus in having two (vs. one) dark narrow irregular bars on the caudal fin, longer pectoral spine (19.3-22.4% SL vs. 15.2-18.6), longer caudal fin (33.5-40.0% SL vs. 25.7-31.9) with pointed (vs. rounded) lobes, longer nasal and maxillary barbels (63.1-81.1% HL vs. 31.3-51.5 and 86.2-125.3% HL vs. 70.9-91.3 respectively; nasal barbel reaching to dorsal insertion of opercular flap vs. to just beyond posterior orbital margin and maxillary barbel reaching just beyond base of last pectoral-fin ray vs. to base of pectoral spine), a straight ( vs. crescentic) premaxillary tooth patch, a more sharply tapering snout when viewed dorsally and an even (vs. slightly convex) predorsal profile (Ref. 74936).Description: dorsal fin with spinelet, spine and 7 rays; anal fin with iii9; iv,9; iii,10 or iv,10 rays; pectoral fin with 6i or 7 rays; pelvic fin with i5 rays (Ref. 74936).
