Diagnosis |
This species is distinguished by the following characters: pectoral rays 16-18 (usually 17); gill rakers 6-7 + 20-25 = 26-31; body moderately elongate, depth 3.3-3.7 in SL; head length (HL) 2.6-3.0 in SL; snout length 1.45-2.1 in HL (relatively longer with growth); barbel length 1.4-1.6 in HL; longest dorsal spine 1.15-1.75 in HL (longer with growth); penultimate dorsal soft ray about equal to last ray in young, 1.2 in last ray in large adults; pectoral fins 1.5-1.75 in HL; pelvic fins 1.35-1.6 in HL. Colour of body whitish with a dark brown to black stripe (red on fish in deeper water) from upper lip through eye to below posterior part of second dorsal fin or anteriorly on upper caudal peduncle; body above stripe yellow or yellowish gray; body below whitish, scale edges narrowly gray to brownish red; a black or red spot larger than eye at the midbase of caudal fin; some large adults with centers of scales below dark stripe pale blue, the edges yellow or with yellow spots, especially posteriorly; peritoneum dark brown (Ref. 54393). |
