Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 13 - 14; Dorsal soft rays (total): 9 - 11; Anal spines: 3; Anal soft rays: 8 - 9. Diagnosis: A large haplochromine cichlid fish characterized by the following combination of characters: a black bar between the eye and the corner of mouth, rounded orange spots on the anal fin in adult males, scales ctenoid, outer jaw teeth bicuspid, inner teeth tricuspid, 16 scales around the peduncle, no papillose swelling on either side of pharynx, lower limb of first gill arch with 7-8 gill rakers, dorsal fin with 13-14 spines and 9-11 soft rays, anal fin with 3 spines and 8-9 soft rays, 29 or 30 lateral line scales, lower pharyngeal dentition with enlarged molariform teeth in the central rows (Ref. 112399).
Found in Lake Boukou with emergent aquatic vegetation, mainly Cyperus laevigatus, Typha australis and Phragmites australis, covering approximately the two-thirds of the lake's surface; submerged macrophyte beds include Potamogeton (Ref. 112399).
