Dorsale stekels (totaal) : 14 - 17; Dorsale zachte stralen (totaal) : 8 - 10; Anale stekels: 3; Anale zachte stralen: 8 - 10; Wervels: 29 - 30. Diangosis: body moderately elongate, the head having a rather 'heavy' appearance (Ref. 42172). Snout somewhat blunt; mouth moderately oblique (Ref. 42172). Tip of the lower jaw always slightly protruding, rostral outline of lower jaw slightly convex (Ref. 42172). Strongly recurved unicuspid teeth in the oral jaws (Ref. 42172): 52-64 teeth in outer row of the premaxilla, 36-56 teeth in outer row of the lower jaw (Ref. 42172). Pectoral and pelvic fins not quite reaching the anal fin; anal and dorsal fin not reaching base of caudal fin (Ref. 42172). Cheek and nuchal area with cycloid scales only, gill cover with more cycloid scales than weakly ctenoid scales; scales on nape and body ctenoid (Ref. 42172). Live colors for males and females are black on ventral parts of head and body (Ref. 42172, 74923) and orange dorsally (Ref. 42172). All median fins orange; males and females have black pelvic fins (Ref. 42172). No midlateral band (Ref. 74923).
Body shape (shape guide): fusiform / normal.
