Dorsal spines (total): 14 - 16; Dorsal soft rays (total): 12 - 13; Anal spines: 3; Anal soft rays: 8 - 10. Diagnosis: upper profile of head strongly convex; lower pharyngeal bone about as long as broad, and with anterior lamella shorter than toothed area; dorsal fin with 14-16 spines and 12-13 soft rays; large vertical bands on flanks poorly marked; no bifurcated dark vertical bars on flanks; base of scales on flanks with dark line; dorsal and anal without orange-red upper margin; caudal without spots, greyish above, yellow below (Ref. 53405). Description: outer jaw teeth bicuspid and non-spatulate, inner jaw teeth and posterior pharyngeal teeth tricuspid; micro-gillrakers present; scales cycloid (Ref. 53405). Coloration: in life: ground color silvery, changing to whitish on belly and to yellowish-green on back and top of head; all scales on sides with black spot at base; sides with 6-8 rather indistinct darker cross bars; upper surface of snout dark green; lower lip, breast and belly white; dorsal fin greyish to transparent, with distinct "tilapian" spot, and some light lines between spines and on soft part, as well as some dark and light bands or light round spots; caudal fin unspotted, its upper part greyish and lower yellowish; anal fin greyish, its distal margin darker; pelvics greyish to blackish, white-edged anteriorly; pectoral fins transparent or sometimes tinged with yellow at base; breast and belly sometimes reddish or blackish after preservation (Ref. 53405).
