P. L. Sclater and Salvin, 1869,
Usually treated as a race of A. dorbignyi. Sometimes split, a view adopted here on account of its duller, greyer head sides and supercilium (2); greatly reduced rufous in wing (2); large overall size with longest wing (at least 1); and seemingly structureless song, with a wide variety of paces and pitches (3), and with unique fairly low-pitched rounded overslurred notes (2)#R. Undescribed taxon from Ayacucho (SW Peru) very distinctive in plumage, but rather similar in voice to present species; probably represents either a race of present species or a separate species#R. Monotypic.
W slope of Andes of SW Peru (Lima S to Tacna and S Puno), N Chile (Tarapacá) and W Bolivia (SW La Paz, NW Oruro).
