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).
Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 16.6 cm SL maschio/sesso non determinato; (Ref. 28013)
Raggi dorsali molli (totale) : 10; Spine anali: 0; Raggi anali molli: 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).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00541 - 0.02797), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.4 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 (10 of 100).
Nutrients (Ref.
124155): Calcium = 215 [79, 551] mg/100g; Iron = 2.59 [1.23, 5.91] mg/100g; Protein = 18.7 [16.7, 21.0] %; Omega3 = 0.551 [0.202, 1.568] g/100g; Selenium = 45.6 [18.3, 132.4] μg/100g; VitaminA = 41.9 [14.7, 113.8] μg/100g; Zinc = 2.68 [1.79, 3.98] mg/100g (wet weight);
