Thought to be closely related to O. chimborazo, O. estella and O. leucopleurus, and all four have been considered conspecific; separated largely on morphological grounds. Present species frequently lumped into O. estella, but differs on account of male having metallic (not glittering) green vs matt buff-brown crown and upperparts (3); male having blackish vs chestnut belly stripe and whiter vs buffier belly sides (2); both sexes having stronger blue metallic tail (ns[1]); female having bronzy crown (ns[2]); female having green-spotted vs brown-spotted throat (2). Monotypic.

Distribution:

Andes of N & C Peru (Cajamarca, Huánuco); reported from extreme S Ecuador (SE Loja).
