Cnemathraupis

Cnemathraupis is a small genus of mountain tanagers found in forest and woodland in the Andes of South America. The two species are uncommon and relatively large tanagers with a contrasting blue, yellow and black plumage (golden-backed mountain tanager also has some brown; black-chested mountain tanager some green).

Taxonomy and species list

These species were formerly included with the hooded mountain tanager in the genus Buthraupis. A molecular phylogenetic study published in 2010 found that Buthraupis was polyphyletic.[1] To create monophyletic genera, the black-chested mountain tanager and the golden-backed mountain tanager were moved to the resurrected genus Cnemathraupis that had been erected by Thomas Penard in 1919 with the black-chested mountain tanager as the type species.[2][3] The genus name combines the Ancient Greek knēmē meaning "leg" or "shin" and thraupis, an unknown small bird.[4] The genus is sister to the grass-green tanager in the monotypic genus Chlorornis.[5]

The genus contains the two species:[3]
