Africa: Sanaga River in Cameroon to the Chiloango River in Angola (Ref. 28013, 80290). Also widely distributed in the Congo River basin (Ref. 11970, 28013, 42019, 80290).
Tamanho / Peso / Idade
Maturidade: Lm ? range ? - ? cm
Max length : 16.6 cm SL macho/indeterminado; (Ref. 28013)
Raios dorsais moles (total) : 10; Espinhos anais: 0; Raios anais moles: 14 - 16. Diagnosis: fronto-parietal fontanel absent in adults, sometimes pore-like in juveniles; snout short, more than 3x head lenght; dorsal fin origin at same level as, or just behind, pelvic fin insertion; sexual dimorphism affecting anal fin shape; head length/snout length 3.1-3.7; 24-30 lateral line scales; 4.5 scales between lateral line and dorsal fin; 9.5-11 predorsal scales; 11-13 anal fin branched rays; 16-21 gill rakers on lower limb of first gill arch; 8 teeth in outer premaxillary row; adults medium-sized; humeral spot always present; broad black band on flanks; most apparent part of this band not reaching or extending beyond vertical through posterior base of dorsal fin (Ref. 80290).
Body shape (shape guide): fusiform / normal.
Affinities: close to B. taeniurus and B. opisthotaenia; body with clearly wider band than the former; dark band starts less forward than in B. opisthotaenia, originating slightly posterior to vertical through dorsal fin origin in B. kingsleyae, but originating at a vertical through dorsal fin origin in B. opisthotaenia (Ref. 80290).
