Head length short, 23.4% of standard length, eye large, bony orbit diameter 43.9% of head length (Ref. 127185). Mouth terminal, lower jaw prominent and slightly prognathous, lower lip thick; premaxilla with two teeth in outer row, each bearing 3 cusps, positioned opposite interspaces between and alternating with 4 inner row teeth bearing 4-5 cusps; four outer row teeth on each dentary, the first 3 bearing 5 cusps, and the 4th greatly reduced in size bearing 3 cusps; two small, conical, symphyseal teeth located immediately behind outer row series on dentary (Ref. 127185). Dorsal-fin rays ii,7-8; fin positioned midway between snout and caudal-fin base, origin at, or slightly behind, pelvic-fin insertion; first two branched rays somewhat elongated but not filamentous; anal fin iii,17-18 rays; no hypertrophy or posterior curvature of anal fin in males; caudal fin forked, with 8 upper and 9 lower principal rays, no median filamentous extension (Ref.127185). Scales in longitudinal series 26-27 to caudal flexure, 4-5 transverse scales between longitudinal series and dorsal-fin origin, 3 transverse scales between longitudinal series and pelvic-fin insertion; pored scales in truncate lateral line 7-8; circumpeduncular scales 10 (Ref. 127185). Vertebral count 31-32; twelve to 13 pleural ribs, first with prominent rounded expansion on anterior face in upper third; six tubular supraneurals located between interspaces of neural spines of vertebral centra 4-10 (Ref. 127185).Colouration: In preservation, base body colouration yellowish, darker dorsally and with an overlay of silver iridescence ventrally along flanks; snout and dorsum of head dark brownish black, cheek silver with patches of melanophores; a prominent pattern of black pigmentation encircling scales of longitudinal series along and below midline extending from posterior border of opercle to base of caudal fin, becoming broken into a zigzag band posteriorly along flanks and caudal peduncle; no trace of a humeral blotch; dorsal and adipose fin greyish black, anal fin dusky, pectoral and pelvic fins hyaline with darkly pigmented leading edges; median rays of caudal fin somewhat darker than above and below (Ref. 127185). Colouration and pigmentation shortly postmortem like that in preservation, but generally more intense (Ref. 127185). Stiassny, M.L.J., E. Alter, R.J.C. Monsembula Iyaba and T.L.D.
