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).

شعاع نرم باله پشتي (کل) : 10; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 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).
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).
