d’Orbigny and Lafresnaye, 1838,
La Paz and Potosí, Bolivia.
Thought to be closely related to O. chimborazo, O. stolzmanni and O. leucopleurus, and all four have been considered conspecific; separated largely on morphological grounds; the last-mentioned overlaps slightly with present species, and some hybridization reported, but despite this it is the form least frequently lumped into present species; O. stolzmanni frequently considered a race of present species, including in recent guide#R, but see below. Two subspecies recognized.
