Hitherto considered conspecific with P. exsul, but (although voices appear identical) differs in its white spots on wing-coverts (3); brighter underparts in female (1); paler grey underparts in male (1); olive-chestnut vs dark chestnut upperparts in both sexes (ns[1]); shorter tail (effect size −4.9, score 2); narrow zone of hybridization (2). Two subspecies recognized.
