Recent study suggested that this species is closest to A. quadribrachys, these two being sister to A. atthis and A. coerulescens#R. Formerly considered conspecific with A. atthis. Regional variations in wing length and bill depth are slight and often regarded as insufficient to warrant racial separation. Three subspecies tentatively recognized.
