Atico, Arequipa, Peru.
Sister to P. steinbachi (which see); see also P. humicola. Formerly considered closely related to or even conspecific with Asthenes modesta, but DNA data#R#R reveal that the two are not even congeneric. Supposedly smaller birds from the lomas of Lachay region (having greyish-rose cast and very dark central rectrices with dark rufous webs) described as race lachayensis, and those from higher Andes from Lima S to Arequipa proposed as race monticola (said to differ from birds of coastal lomas in larger size, browner, less ochre, upperparts, darker central rectrices, somewhat darker throat patch, and less uniform underparts with more contrasting darker sides and flanks); although recognized by some authors#R, both populations appear to be products of clinal variation combined with differences in degree of plumage wear, and described characters do not permit diagnosis of individual specimens. Monotypic.
W slope of Andes of SW Peru (W La Libertad#R and Lima S to Arequipa).
