Description: Dorsal fin with 13-14 spines and 9-11 soft rays; anal fin with 3 spines and 8-9 soft rays; caudal fin with 23 soft rays; pectoral fin with 13 soft rays; pelvic fin with 6 rays (Ref. 112399). Two lateral lines with 18-20 and 5-11 scales perforated on the upper and lower lateral lines respectively; 27+2 or 28+2 lateral line scales; 5.5 scales between lateral line and origin of first dorsal fin; 10-11 scales between lateral line and midventral body profile; 4 or 5 scales between the pectoral and pelvic fin bases; 2 scales between the upper and lower lateral lines; 16 scales around the peduncle; scales ctenoid (Ref. 112399). Seven to eight gill rakers on lower limb of first gill arch, total 10-13 on first gill arch; outer jaw teeth bicuspid; inner teeth tricuspid; no papillose swelling on either side of pharynx; lower pharyngeal bone and dentition: dentigerous surface approximately equilateral, teeth forming the median rows enlarged with molariform and submolariform crowns (Ref. 112399).
Colouration: In life, head and body light brown or silver; a vertical black bar between the front lower part of the eye and the part of the head immediately posterior to the corner of the mouth; two median incomplete horizontal black bars between the eyes; a vertical black bar in the middle of the opercula; a black spot present on the postero-dorsal angle of the opercula; 6-7 black cross bars that descent below the midlines of sides; two or three rounded orange spots clearly apparent on the anal fin, these spots without contrasting border and without translucent surround; no tilapian mark at the beginning of the soft part of the dorsal fin; fine orange spots at the basis of the soft rays of the dorsal fin (Ref. 112399). In preservative, head and body brown with black bars poorly contrasting; spots on anal fin unpigmented (Ref. 112399). |
