Natal, South Africa.
In the past treated as conspecific with V. purpurascens. Formerly considered conspecific with V. chalybeata. Has been treated as conspecific with V. wilsoni, V. nigeriae, V. camerunensis and V. codringtoni, but differs from first two in size, plumage and song mimicry; differs from V. camerunensis in morphology, and molecular studies indicate no recent common ancestor; sympatric with V. codringtoni without interbreeding, and the two parasitize different host species. Possibly interbreeds with V. chalybeata in S DRCongo. Race nigerrima sometimes treated as a full species. Indigobirds with green to blue breeding plumage in W DRCongo (Kwamouth, Bandundu) may be of this species; field studies needed. Described taxa V. funerea lusituensis and V. funerea sorora are synonyms, respectively, of V. codringtoni and V. camerunensis. Two subspecies recognized.
