Morfologia | Morfometria
Espinhos dorsais (total): 0; Raios dorsais moles (total): 22-24; Espinhos anais 0; Raios anais moles: 26 - 28. Diagnosis: Petrocephalus mbossou is distinguished from all other Petrocephalus species in Central Africa by the following combination of characteristics: dorsal fin with 22-24 branched rays; anal fin with 26-28 branched rays; mouth inferior and small, with ration head length and mouth width 4.2-5.1, with 9-11 teeth in a single row in the upper jaw and 14-22 teeth in a single row in the lower jaw; distance from the anterior extremity of the snout to the corner of the mouth only 2.8-3.4 times in head length (Ref. 85331, 113655). Weak pigmentation pattern with the presence of two black markings on each side of the body: (1) an irregular patch below the anterior base of the dorsal fin (first to sixth/seventh rays); (2) an irregularly-shaped mark centered at the base of the caudal fin that does not extend onto the rayed portions of the upper and lower caudal fin lobes (Ref. 85331).
