Subspecies
Occasionally hybridizes with Red-cheeked Cordonbleu (Uraeginthus bengalus) in southern Tanzania (Songea, Mikindani), where a few males have red patch on the ear-coverts. Males with red on ear-coverts occur rarely in southern Zambia and northern South Africa (in areas remote from Red-cheeked Cordonbleu (Uraeginthus bengalus)) and one record in north-western Zambia (near range of latter), but the two species are broadly sympatric in northern and central Tanzania and in south-eastern DRCongo (Kasai and Katanga), where little evidence of interbreeding.
Proposed subspecies natalensis (described from KwaZulu-Natal, in eastern South Africa) treated as a synonym of niassensis.
cyanopleurus Wolters, 1963 - Southern Angola, western Zambia (west of Kafue National Park), western and north-western Zimbabwe, northern Namibia, northern Botswana and northern South Africa (south to North West Province and Free State).
niassensis Reichenow, 1911 - Tanzania, southern and south-eastern DRCongo, Zambia (east of Kafue National Park), Malawi, Mozambique and Zimbabwe (except west) south to north-eastern South Africa (northern Limpopo south to KwaZulu-Natal and eastern Cape) and Swaziland.
