Commonly treated as conspecific with D. blissetti and D. jamesoni. Differs from both in its lack of chestnut lower neck sides (3); yellow-tinged underparts (2); song a descending series of 4–6 short whistles (first note above 5000 Hz) vs in blissetti a series of short notes at same pitch (3500–3800 Hz), hence structure very different (3) and pitch slightly higher (1)#R, and in jamesoni a repeated single or double note with fairly constant pauses (3800–4500 Hz), hence structure very different (3) and frequency range much smaller (3); moreover, dark on breast extends (as it does in jamesoni) much farther down than in blissetti (2); and populations of present species and blissetti are altitudinally parapatric (3) in vicinity of Mt Cameroon. This split supported by genetic evidence#R. Hybridization suspected in W Angola with D. ansorgei (which see). Monotypic.
