J. F. Gmelin, 1789,
Tahiti, Society Islands.
Member of a large species-group distributed from Australia to Micronesia and Polynesia; monophyly of this group (and subgroups) supported by genetic data#R; forms a subgroup with P. perousii, P. huttoni, P. insularis, P. chalcurus, P. coralensis, P. chrysogaster and P. rarotongensis, with P. dupetithouarsii and †P. mercierii also sometimes included, although the genetic data place these last two apart; the other large subgroup consists of P. pelewensis, P. richardsii, P. roseicapilla, P. ponapensis, P. hernsheimi, P. greyi, P. porphyraceus and P. fasciatus; other, more distant members of the species-group are P. coronulatus and P. regina; in past, P. superbus (with P. temminckii) sometimes included in the group, but the genetic data place it elsewhere. Taxonomic limits of present species have been variously interpreted: hitherto considered conspecific with P. chrysogaster but differs from that species in yellowish-grey vs greenish-yellow mid-belly to pale yellow vs bright yellow vent, with yellowish-grey vs bright yellow on lower belly (3); indistinct superciliary line and darker, mauve, crown (1); narrow, vague part-white subterminal tailband vs broad clear whitish-yellow terminal tailband(2). Some authors consider P. coralensis and P. chalcurus, and perhaps also P. insularis, to be races of present species; others treat P. chalcurus and P. chrysogaster as races of P. coralensis. Race frater differs only rather slightly from nominate, and may be of questionable validity. Two subspecies recognized.
