Closely related to A. taciturnus, A. flavirostris, A. schlegeli and A. abeillei, the present species being sister to the last-named#R. Recent study found evidence of substantial genetic differentiation between populations of this species in Panama, but the significance of this requires further research#R. Eight subspecies recognized.
