Sometimes considered closely related to Oreolais pulcher and O. ruwenzorii, but genetic evidence indicates otherwise, and these species have ten (not twelve) rectrices. Until recently considered conspecific with A. flavigularis, A. lynesi and A. fuscigularis, and molecular evidence suggests these are, indeed, nested among other races of present species, despite their morphological distinctiveness. Many races in the largely contiguous populations of S Africa intergrade over considerable distances, suggesting synonymization appropriate, e.g. claudei and capensis could be subsumed into nominate, darglensis into venusta, lebomboensis into drakensbergensis, spelonkensis into flaviventris, and arnoldi into rhodesiae. However, there are three major genetic divisions among populations in S Africa: S of R Tugela, in South Africa; R Tugela to R Limpopo; and Zimbabwe. Proposed race iringae (Tanzania) merged with griseiceps. Full review desirable. Race whitei sometimes listed as bensoni, but that name preoccupied by a synonym of A. chapini strausae. Nineteen subspecies recognized.
