Diagnosis

The species is distinguished from its congeners by the following set of characters: with a dark anteriorly oblique blotch in the humeral region, its anterior limit slightly ahead of vertical through the spinelet, and its posterior limit at vertical through the base of second branched dorsal-fin ray; 47-49 total vertebrae; 8-11 retrorse triangular, broad-based and strongly inclined

dentations confined to basal three-fourths of pectoral-fin spine posterior margin; presence of an unpigmented region dorsally and ventrally adjacent to the dark midlateral stripe; maxillary barbels reaching at least the caudal fin insertion; the longest ray of dorsal-fin 18.7-22.5% SL; subequal caudal-fin lobes; dark midlateral stripe narrow, from pseudotympanum to the caudal-fin insertion, dorsal region of body without dark stripes; dorsal fin with hyaline stripe near base, followed distally by a dark stripe, then another hyaline stripe and distalmost two-fifths dark (Ref. 118150).

Description: D I,6; A iv-vi,11; Pectoral-fin rays I,9; Pelvic-fin rays i,5
