Has been included in genus Chaetopus. Recently proposed reorganization of Francolinus places present species in genus Pternistis with 23 other species.
Various subspecies proposed, including sharpii, konigseggi and nigrosquamatus, but geographical variation in plumage is complex and validity of subspecies is dubious.

clappertoni (Children & Vigors, 1826) - Sub-Saharan Africa (Mali to Sudan and Ethiopia).
koenigseggi (Madarász, 1914) - Eastern Sudan.
