no locality = Missahoe, Togo.
Hitherto treated as conspecific with D. castanea, but differs in its white hindcollar in male (3); narrower black breastband in male (16 hormophora from Liberia mean 10.1 mm s.d. 1.9 vs 18 castanea from Cameroon 18.6 s.d. 3.7; effect size −2.9, score 2); larger (laterally and vertically; measurements here lateral) supraocular wattle (16 males each taxon, mean 10 mm s.d. 0.82 vs 8.1 s.d. 0.71, effect size 2.45, score 2); shorter bill (effect size −1.66, ns); chestnut on female breast reaching less far (at least 1). Molecular evidence#R supports this split, and a report exists of D. castanea in Gabon not responding to playback of calls of present species from Ivory Coast#R, although much more work needed to determine genuine differences in acoustic signals of these taxa. Monotypic.
