Description synthétique Morphologie | Morphométrie

Diagnosis: Petrocephalus odzalaensis is distinguished from all other Petrocephalus species in Central Africa by the following combination of characteristics: dorsal fin shorter than anal fin; dorsal fin with a maximum of 22 branched rays; anal fin with a minimum of 27 branched rays; mouth sub-terminal, ratio between head length and mouth position is between 4,2 and 5,0; and eye small, the ratio head length and eye-diameter between 3,7 and 4,2 (Ref. 85331). Body pinkish-gray, darker dorsally, with the presence of three distinct pigmentation patches: (1) a distinct ovoid black mark situated below the anterior base of the dorsal fin on each side of the body; (2) a small black mark at the base of each pectoral fin; (3) an ovoid black mark on each side that is centered at the base of the caudal fin, not extending onto the upper and lower lobes of this fin (Ref. 85331).
