Etymology: Petrocephalus: Latin, petra = stone + Greek, kephale = head (Ref. 45335); mbossou: The specific epithet is the name given to Petrocephalus locally in the Lingala language; speakers of Lingala recognize Petrocephalus as a natural group, which they call 'mbossou' (Ref. 85331).

Africa: middle Congo River basin: Lékoli River (Likouala River tributary) in Republic of Congo (Ref. 85331), and the Ubangui River in Central African Republic (Ref. 113655).
Größe / Gewicht / Alter
Geschlechtsreife: Lm ?  range ? - ? cm
Max length : 12.7 cm SL Männchen/unbestimmt; (Ref. 85331)
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 22 - 24; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 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).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
