A distinctive form of uncertain affinities; genetic data suggest close to Chrysoena and P. nainus#R; in past, was associated with a species-group that included P. hyogastrus, P. granulifrons, P. iozonus and P. insolitus; P. nainus was sometimes included in this group. At least eleven races have been described, based on slight differences in size and coloration, but even those listed here are doubtfully distinct#R; in addition, talautensis (Talaud Is) and loloda (Doi I) are included in xanthorrhous, pelingensis (Banggai Is) in chrysorrhous, and massoptera (Kangean Is and Matasiri), aurescentior (Kaledupa, in Tukangbesi Is) and margaretha (Kalaotoa) in melanauchen; further study needed to establish which of the described forms merit subspecific recognition. Species has sometimes erroneously been listed as P. melanocephalus. Five subspecies tentatively recognized.
