Hitherto (apart from in detailed original description#R) treated as conspecific with S. verticalis, but differs in its larger size, best reflected perhaps in longer and proportionately more graduated tail (allow 2); broad white tips on the three outermost rectrices (3); white vs grey-mottled or grey lower back and rump (2); and significant differences in immature plumage, notably orange-rusty vs (brown-tinged) grey forehead, chin and head sides (2). Monotypic.


Djaul I, off NW New Ireland (Bismarck Archipelago).
