Previously considered conspecific with A. flavicollis, but recognition as species made in molecular study#R without supporting evidence. Differs in its pale yellowish-white (nominate) to whitish (soror) vs bold yellow chin and throat (3); pale grey-tinged olive-green vs grey-tinged olive-brown breast and flanks (2); large whitish mid-belly and pale grey-brown vent vs olive-brown mid-belly and vent (2); shorter tail in soror (effect size −3.12, score 2), although not in nominate; but HBW reports some vocal differences, A. flavicollis in Mali not responding to playback of song of soror. Proposed race simplicicolor (E Cameroon) not safely distinguishable from soror; pallidigula (Entebbe, in Uganda) averages rather darker overall than nominate, but not satisfactorily separable. Two subspecies recognized.
