G. R. Gray, 1867,
Commonly considered conspecific with R. rufescens, but differs notably in voice, song being at start rather similar to that of R. rufescens but finishing very differently, and appearing louder, perhaps because populations are more spread out and need to call between distant ridges#R (allow 3); in ecology, with distributions largely discrete altitudinally, and bands of unsuitable forest habitat isolating upland grassy ridges of present species from lowland grasslands preferred by R. rufescens, in both Bolivia and Argentina#R (1); and in plumage, males having broadly buff-streaked vs narrowly buff-scaled crown (latter appearing as blackish cap above plain neck, former more continuous with neck markings), facial markings more broken up and spotty (ns), spotted vs plain neck and barred vs plain breast (3), more broadly and extensively barred vs more restricted and more narrowly barred wing-coverts (1), and uniformly cream underparts with dark bars from breast-sides to flanks vs pale grey breast to darkish grey vent with vague bars on lower flanks (3). Monotypic.
W Bolivia (from S La Paz) S to NW Argentina (to Catamarca and Tucumán).
