Some authors include present species in a superspecies with A. javanica and A. brunneopectus, and all three are sometimes considered conspecific; others attribute morphological similarities to convergent evolution; sometimes A. rufipectus or A. hyperythra, or both, also included in the superspecies. Race campbelli sometimes considered to constitute separate species. Four subspecies normally recognized.
