Otidiphaps nobilis aruensis
Affinities uncertain. Hitherto considered one of four distinctive subspecies grouped under the name O. nobilis, but here treated as full species (see under O. nobilis). 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).Monotypic.
