“Probably procured on some one of the islands of the Eastern Archipelago or in New Guinea”.
Affinities uncertain. Hitherto considered the nominate race of a species consisting of four distinctive races, but here each is treated as a full species, with the following diagnoses. The form aruensis (Aru Is) differs from nobilis in its white vs glossy amethyst/greenish hindneck (3); much less coppery nuchal area to mantle (2); greenish-blue vs purplish-blue breast (2); slightly paler, less maroon-tinged mantle (ns); and shorter, virtually undetectable crest (1, scored as a mensural character, not plumage character). The form cervicalis (SE New Guinea) differs from nobilis in its greyish-white vs glossy amethyst/greenish hindneck (3); brownish vs coppery nuchal area to mantle (2); dark turquoise-green vs purplish-russet to deep blue lower back to uppertail-coverts (3); and blackish-green vs black-blue underparts (ns). It differs from aruensis in its much smaller and greyish-white vs pure white and more extensive (to mantle) hindneck (3); dark turquoise-green vs purplish-russet to deep blue lower back to uppertail-coverts (3); blackish-green vs black-blue lower underparts (1); and slightly darker, more maroon-tinged back and wings (as in nobilis), aruensis lacking the maroon, being a shade more rufous (ns). The form insularis (Fergusson I) differs from all other taxa in Otidiphaps in possessing no backward-directed crest (2); no coloured nuchal patch (simply blackish) (3); wings markedly paler rufous than in other taxa (ns); rump dull green (strong green in cervicalis, dark blue in others), uppertail-coverts and tail dark blue (strong green in cervicalis, dark blue in others) (ns); underparts dull matt black, with virtual absence except slightly on breast of the glossy blue or green that is extensive on other taxa (2). Monotypic.
Batanta, Waigeo and Yapen#R, and mountains of W New Guinea (Arfak, Wandammen, Weyland, Snow, and mountains on upper Mamberamo R).
