Closely related to P. icterinus (see below). Birds from Cameroon (N & W of Mt Cameroon) described as race serlei on basis of paler and duller yellow underparts, with darker olive wash on breast, but these characters fall within range of variation of the species elsewhere. Monotypic.

Distribution:

Extreme SE Nigeria and W Cameroon E to SW Central African Republic, S to C Gabon and NE Congo; also EC DRCongo E to W & S Uganda and extreme NW Tanzania. Distribution probably not fully resolved owing to confusion with P. icterinus.
