Hitherto treated as conspecific with P. atripennis and P. rubiginosus, but differs from latter (which is much closer in both morphology and range) by its grey vs blackish crown (behind black forehead) (3); paler chestnut plumage (1); chestnut vs grey-scaled throat (2); and considerably smaller size (mean male tail 75.8 vs 82 but n=2 for P. rubiginosus; allow 1). Reported to intergrade with P. rubiginosus eastwards from Nigeria towards Central African Republic, in zone where precise distribution is unclear and very local. Monotypic.
N Congo#R, S Central African Republic and NE DRCongo E to SW Uganda.
