Belongs to the large species-group centred on P. purpuratus (which see); within this, forms part of the subgroup centred on P. porphyraceus. In recent years considered conspecific with P. porphyraceus, also incorporating P. ponapensis and P. hernsheimi, but here considered a full species. Differs from ponapensis in having blurry black bar on mid-belly with dull rust-brown upper belly patch vs broad brown-tinged black blurry patch covering same area (2); more yellow on lower belly patch (2); narrower yellowish tail-tip (2); greyer, less yellow-shot breast, mantle and hindcrown (ns); longer wing (effect size 1.73, score 1). Differs from hernsheimi in having blurry black bar on mid-belly (2); dull rust-brown upper belly patch (3); more yellow on lower belly patch (ns); tail-tips yellowish vs strong yellow and broader (2); longer wing (effect size 2.58, score 2). Proposed race graeffei (Wallis and Futuna) and Niuafo’ou (N Tonga) are probably hybrid populations of present species × P. porphyraceus. Monotypic.
Samoa and American Samoa. Also Wallis and Futuna, and Niuafo’ou (Tonga), where populations are probably hybrid.
