🐟 Physical Description

Dorsal spines (total): 2; Dorsal soft rays (total): 5 - 6; Anal soft rays: 17 - 18; Vertebrae: 44 - 45. Easily distinguished from all other species of the genus by a pigmentation pattern of a light, midlateral stripe on a dark background instead of either a uniform color pattern in adults (Pseudomystus inornatus and P. robustus) or a color pattern of light, transverse bands and/or blotches on a dark background (all other species). Also differs from all other congeners by a strongly depressed head and deeply forked caudal fin with very long, lanceolate lobes, strongly asymmetric, upper lobe longest (vs. moderately depressed head and caudal fins with triangular lobes that are subequal, with upper lobe slightly longer) .: elongated.
