Hitherto considered one of four subspecies in O. guerinii, although HBW noted possible treatment as four separate species. Uniquely possesses tan-and-black crest (where the other three possess white and black feathers) (3); short tan beard with green then purple reflectant spots centrally (3); buffy neck sides (white in the other three taxa) and buffier, brownish-tan belly (ns[1]); and broad buffy-white line on outer rectrix, with buffy line around shaft of next two outer feathers (3)#R. Specific name sometimes spelt stubelii, but based on a German name, so umlaut of original spelling requires emendation by addition of the following “e”. Monotypic.

Distribution:

C Colombia (Nevado del Ruiz, on Tolima–Caldas border).
