Subspecies
Genus often subsumed in Nectarinia. Genus names Leptocoma and Chalcostetha described simultaneously, and former has been selected by First Reviser as having precedence. Probably closest to Crimson-backed Sunbird (Leptocoma minima). Geographical variation minimal.
Other proposed subspecies, both from peninsular India, are whistleri (described from Muddur, in Karnataka) and sola (from Pondicherry, in Tamil Nadu), both considered unsustainable and included in flaviventris.
The following 2 subspecies are recognised:
flaviventris (Hermann, 1804) - Peninsular India (east to western Meghalaya) and Bangladesh.
