Asthenes d’orbignyi usheri
Ninabamba, 7000 feet [c. 2130 m], Pampas River Valley, Ayacucho, Peru.
Usually treated as a race of A. dorbignyi, but sometimes as a race of A. huancavelicae. Has alternatively been considered a full species, and this view adopted here on basis of its large bill (sample size small, but at least 2); whitish vs cinnamon (or darker) outer rectrices (2); and song which is closest in structure to A. huancavelicae but much shorter (at least 2) and both much higher-pitched (3) and flatter-pitched (ns)#R. Monotypic.
Andes of SC Peru (Pampas and upper Apurímac drainages).
