Diagnosis |
Distinguished from all its congeners by its unique caudal-fin pigmentation pattern, consisting of an approximately symmetrical pattern of small black blotches on both upper and lower caudal-fin lobes. Can be further diagnosed from other species of Psilorhynchus by the combination of the following characters: snout length 53-55% HL; ventral surface between paired fins with a broad rectangular scale-less patch; dorsal fin with 9 branched rays; pectoral fin with 5 unbranched rays; caudal fin with 9+9 rays; scales on lateral line 32-33; lateral sides of body marked with 6 indistinct round to squarish dark-brown blotches, arranged in a longitudinal row; dorsal saddles deep, extending 3-4 scale rows downwards from the dorsal surface, in contact with the round to squarish dark brown blotches, arranged in a longitudinal row on flank (Ref. 85329). Description: Dorsal-fin rays iii.9; anal-fin rays ii.6; pectoral-fin rays v.11; pelvic-fin rays ii.7 (Ref. 85329). |
