| Diagnosis |
Diagnosis: mouth subterminal; lips weakly or moderately developed, very thick, lower lip with a mental lobe; two pairs of well-developed barbels, anterior pair shorter than posterior pair, the latter measuring 0.67x eye diameter; lower jaw not reaching to anterior margin of eye; 27-31 scales in lateral line; last simple ray of dorsal fin strong and ossified, not serrated, measuring at the most equal to head length; snout 2.5x HL; length of caudal peduncle 2x its height (Ref. 81639). Description: large species; scales longitudinally striated; scale formula: 4.5/27-31/4-4.5/2-3/10-12; D: III-IV, 10; A: III, 5; P: 16; V: 10; lateral line complete but hardly visible; dorsal fin with concave border (Ref. 81639). Coloration: base of each scale is white, distally purplish blue; snout purplish blue; fins are iron grey, and purplish blue proximally; caudal fin grey and bluish proximally; opercle is tinged purplish blue (Ref. 81639). |
