Subspecies
Genus often subsumed in Nectarinia. Subspecies bineschensis poorly differentiated from, and sometimes synonymized with, orphogaster. Moreover, it is isolated from other subspecies of present species, and has been suggested also as being possibly misidentified Golden-winged Sunbird (Drepanorhynchus reichenowi).
Proposed subspecies luehderi (described from Bipindi, in Cameroon) and insularis (Bioko) synonymized with nominate; uellensis (Koloka, Angu and Amadi, on R Uelle, in DRCongo) merged with orphogaster. Females in Cameroon and DRCongo having light yellow pectoral tufts and red breastband but no metallic plumage described as subspecies ogilviegranti, but shown to be aberrantly plumaged females of nominate subspecies.
The following 4 subspecies are recognised:
kempi Ogilvie-Grant, 1910 - Senegal east to south-western Nigeria.
chloropygius (Jardine, 1842) - Bioko I (Fernando Póo) and south-eastern Nigeria east to southern Chad and Central African Republic, south to north-western Angola and western DRCongo.
orphogaster Reichenow, 1899 - Central and eastern DRCongo and southern Sudan south to north-eastern Angola, Rwanda, Burundi, Uganda, western Kenya and western Tanzania.
