No close relatives. Exact delimitation of races difficult owing to intergradation; nominate and flavipunctata hybridize over an extensive zone, roughly from Ghana to S Nigeria; proposed races hybrida (Niger Delta) and chapini (SE Cameroon E to C DRCongo) considered indistinguishable from, respectively, nominate and ansorgii. Nominate hirsuta has been separated as full species from other three taxa#R, but form ansorgii shares characters with both hirsuta and flavipunctata and could be assigned to either; alternatively, three or, indeed, four species may be involved; more study needed. Four subspecies currently recognized.
