Short description
Dorsal spines (total): 13 - 16; Dorsal soft rays (total): 12 - 14; Anal spines: 3; Anal soft rays: 8 - 10. Diagnosis: lower pharyngeal bone about as long as broad, and with anterior lamella shorter than toothed area; median pharyngeal teeth not broadened; dorsal fin with 13-16 spines and 12-14 soft rays; soft dorsal and upper tip of caudal bordered with orange-red; "tilapia" spot clearly marked even in adults; dorsal and caudal fins not or feebly blotched (Ref. 53405). Description: outer jaw teeth bicuspid and non-spatulate, inner jaw teeth tricuspid, posterior pharyngeal teeth tricuspid with the lower cusp rather small; micro-gillrakers present; scales cycloid; pectoral region covered with very small scales (Ref. 53405). Coloration: in life: adults: ground colour greyish to silvery, more whitish on belly and rather dark grey on back, occiput and snout; sides with 5-6 faint cross bars and horizontal band; lower part of cheeks and subopercle bright orange-red, and traces of this colouration on opercle and breast; first 1/4 of spinous part of dorsal fin uniformly grey, posterior part with 2-3 rows of light oblique bars between spines; soft part of dorsal fin with irregular light spots; well visible "tilapian" spot; distal margin of dorsal fin black on spinous part, orange-red on soft part; anal fin dark grey, with distal margin lighter and some light spots posteriorly; pelvic fins with black anterior margin: caudal fin with orange-red upper angle and light spots forming a network on proximal part and transverse series on distal part (Ref. 53405). Juveniles: less colourful than adults; anterior part of spinous dorsal fin and distal areas of soft dorsal and caudal fins darker, with much more black between branched rays (Ref. 53405).
