Muni River, Gabon.
Sometimes (with D. johnstoni) placed in a separate genus Mesopicos along with D. goertae, D. spodocephalus and D. griseocephalus#R; in the past, sometimes separated (with D. johnstoni) in genus Polipicus. Generally regarded as conspecific with D. johnstoni, and birds on Mt Kupé (WC Cameroon), here recognized as race kupeensis, have been considered a hybrid population; re-examination and re-measurement of Mt Kupé specimens, however, show that this population, while intermediate in tail length between the other two, is very close in wing length to johnstoni but has bill length shorter than that of johnstoni, indicating that it is not hybrid but merits status as a subspecies of johnstoni (D. j. kupeensis). On this basis, present species differs from D. johnstoni in having heavy vs no or only light streaking below (3); tail mainly same green as upperparts vs mainly blackish (2); more buffy, less greenish face (supercilium and ear-coverts) (1); larger bill and longer tail (effect size for tail when compared with johnstoni and kupeensis combined 2.2; hence 2). Angolan birds formerly recognized as race gabela or angolensis, but they differ from other populations barely, if at all. Monotypic.
Lowland SW Cameroon and SW Central African Republic discontinuously to Gabon and W Angola (Cuanza Norte S to Benguela), and E across W, SC & NE DRCongo to SW & E Uganda (Kibale S to Bwindi Forest, also Mt Elgon), W Rwanda and W Burundi.
