Subspecies
No subspecies.
Genus formerly subsumed in Anthreptes. Recently, this species and its three congeners were placed in a genus Hedydipna, but this name invalid, current genus name having priority. Forms a superspecies with Pygmy Sunbird (Hedydipna platura), and formerly treated as conspecific. Birds from north-western Ethiopia (Melissai, on Adiabo Plains) with apparently short wing described as subspecies adiabonensis, but considered inadequately differentiated from those elsewhere in species' range.
