Príncipe, Gulf of Guinea.
Studies needed to clarify taxonomic position of races coracinus and atactus, which intergrade fully in SW Nigeria (Ondo and Benin Provinces) and Cameroon. Moreover, coracinus and race divaricatus of D. adsimilis behave more or less as distinct species, differing in behaviour, voice and plumage, with limited hybridization in areas of range overlap (apparent hybrids reported in Nigeria, DRCongo and Angola); atactus initially described as a possible hybrid between those two taxa. Nominate modestus usually treated as a separate species in studies of Príncipe birds#R#R#R, but only evidence presented concerns certain stereotypic calls not found in mainland forms#R; formal study needed. Proposed race ugandensis regarded as a synonym of coracinus. Three subspecies currently recognized.
