Has often been treated as conspecific with A. nigrolutea, but differs in details of morphology, plumage and vocalizations. Delineation of (sometimes well-marked) races complicated by individual variation in amount of black on cap and upper body of males, male eclipse plumages, some broad geographical intergradation zones (especially in Indian Subcontinent), and inter-population convergence (including of colour tones of eclipse plumages). Proposed races singapurensis and micromelaena of Malay Peninsula and islands absorbed within range of variation of horizoptera; forms trudiae (Brunei Bay, in N Borneo) and djungkulanensis (extreme W Java) treated as local intergrades between larger neighbouring entities. Eleven subspecies recognized.
