Hitherto considered conspecific with O. nobilis, but differs on account of (in male) narrower white (scaly towards mid-crown) vs broad violet-purple lateral crownstripes (3); white lateral crownstripe bordered “below” (from in front of eye) by barely visible (unless feathers raised) glittering green feathers (same colour as throat) extending back to hindcrown vs none in nobilis, on which stripe simply broad purple with no glittering green on hindcrown (female likewise has green-spangled vs blue-spangled hindcrown) (2); (in both sexes) russet-purplish-bronzy vs greenish-bronzy rectrices (2). Monotypic.
