See B. graueri. Until recently considered conspecific with B. centralis, but although evidence points strongly to their being separate species, allocation of subspecies and attribution of diagnostic characters still speculative and unsatisfactory; races B. c. sudanensis and B. c. chadensis may belong with present species. Six subspecies recognized.
