Usually considered conspecific with P. aequinoctialis, but differs in its broad white line from lores over mid-crown, and broad (usually unbroken) white line running back from chin to lower and rear edge of ear-coverts, so that the two features appear like goggles or a harness, and possibly less white on chin (3); shorter wing (based on effect size derived from published data#R: score 1); rattle-call characteristics involving frequency (based on published data#R: effect size 2) and call rate (effect size 1) (3). Monotypic.

Distribution:

S Atlantic Ocean, breeding on Inaccessible I (Tristan da Cunha).
