Belongs to the large species-group centred on P. purpuratus (which see); within this, forms part of the subgroup centred on P. porphyraceus. Formerly considered a race of P. ponapensis, but in recent years both commonly lumped into a polytypic P. porphyraceus. Differs from P. ponapensis on account of its green vs broad brown-tinged black blurry belly patch (3); yellow vs whitish-yellow tail-tip (1); greyer, less yellow-shot breast, mantle and hind-crown (1); smaller size (including shorter bill) (effect size for bill –3.54, score 2). Proposed race †marshallianus (Ebon, in Marshall Is) considered a synonym of hernsheimi. Monotypic.
