Recent phylogenetic analyses indicated that this species and A. rufiventris are genetically very close, forming a species pair#R; sometimes considered conspecific. The two have traditionally been considered perhaps to form a species-group with A. striatus, possibly including also A. ovampensis. Birds from mountains of C Asia (Tien Shan) sometimes separated as race dementjevi, but thought probably part of a cline#R; Canary Is population described as race teneriffae, but differences from granti minimal. Many other dubious races described. Six subspecies currently recognized.
