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).
