DNA studies#R indicate that closest relative is D. atripennis. Distinctive race sharpei may merit treatment as a separate species (with saturnus), differing in a series of minor characters: blue vs green sheen in both sexes (1); all-dark vs white-tipped underwing-coverts in both sexes (sometimes reported inversely, in error) (1); female as glossy as male vs less glossy than male (1); female close in size to male vs perceptibly smaller (on wing length at least 1); and almost squared-off vs more obviously forked tail in both sexes (1); but vocal differences not apparent in limited samples available, although recent genetic study supports treatment as separate species#R. Proposed race elgonensis included in saturnus, which may itself be synonymous with sharpei, while populations W of R Niger may represent a further, as yet undescribed, subspecies#R; race tephrogaster appears to be transitional, and may be better included in nominate. Five subspecies recognized.
