Yánac, 15,000 feet [c. 4570 m], Ancash, Peru

Previously placed in genus Leptasthenura, but recent genetic study#R found this species to be sister to S. desmurii. Population of Cochabamba (WC Bolivia), with whitish supercilium and paler underparts than N populations, almost certainly represents an undescribed taxon; specimen material from NW Argentina lacking. Monotypic.

Distribution:

W & SE Peru (Ancash, N Lima, and E Andes in Cuzco and Puno) S to WC Bolivia (La Paz, Cochabamba, Potosí, Tarija) and NW Argentina (Jujuy, Salta).
