Taxonomic Remarks
Affinities: B. taeniurus is close to B. opisthotaenia and especially to B. kingsleyae; however, generally B. taeniurus has no humeral spot and more numerous gill rakers on lower limb of first arch; the more discriminatory character is the longitudinal band shape which is very thin, while larger in B. opisthotaenia and B. kingsleyae (Ref. 80290).

Africa: reportedly endemic to the Lower Guineawhere it is known from the rivers Ogowe, Ntem and Kribi (Kienke) (Ref. 80290) in Cameroon and Gabon (Ref. 5331, 80290), and from the Kouilou-Niari basin (Ref. 92841). However also reported from the Ngoko (Sangha drainage, middle Congo River basin) in Cameroon (Ref. 42792, 51193).
