Subspecies
No subspecies.
Possibly forms a superspecies with Spot-breasted White-eye (Heleia muelleri), but the two seem to be very well differentiated in plumage and vocalizations. Birds from Sumbawa perhaps slightly larger and with perhaps more cream colour on crown, sometimes separated as junior (described from Batu Dulang), but differences from Flores birds considered insufficient to warrant naming of geographical subspecies.
