Africa: Ogowe (Ref. 5331, 80290), Nyong, Lobé, Ntem, Kouilou basins and in Nkomi lagoon (Ref. 80290). Also in the lower, middle (Ref. 80290) and upper (Ref. 5331) Congo and the Malagarasi (Ref. 54847). Reports from Lake Kivu (Ref. 5331, 80290) are based on an erroneous locality interpretation whereby the Kivu Province was mistaken for Lake Kivu (Ref. 46152).

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 10; Spine anali: 0; Raggi anali molli: 18 - 23. Diagnosis: 6.5-7.5 scales in transverse row between lateral line and dorsal fin origin; 12 scales around caudal peduncle (Ref. 74421, 80290); 35-40 (Ref. 80290) or 34-41 (Ref. 74421) lateral line scales. Eye diameter/head length 26-40% (Ref. 80290) or 31.4-43.8 (Ref. 74421). 15-20 (Ref. 80290) or 17-19 (Ref. 74421) anal fin branched rays.

Biologia     Glossario (es. epibenthic)

Affinities: similar to B. macrops but with a higher number of scales around caudal peduncle and a smaller eye (Ref. 80290).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00654 - 0.02211), b=3.02 (2.86 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.3 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (11 of 100).
