Previously placed in Upucerthia. Analysis#R shows present species and O. phoenicurus are together sister to O. melanurus. Differences in coloration of nominate race between N and S extremes (darker and less reddish upperparts in S) indicate either strong clinal variation or perhaps an undescribed race. Three subspecies currently recognized.

Subspecies and Distribution
  • O. r. montanus (d’Orbigny & Lafresnaye, 1838) – Andes of S Peru (Arequipa to Tacna), Bolivia (La Paz S to Potosí), N Chile (Tarapacá, and probably E Antofagasta) and N Argentina (Jujuy S to Catamarca).
  • O. r. famatinae (Nores, 1986) – NW Argentina (Sierra de Famatina, in La Rioja).
  • O. r. ruficaudus Meyen, 1834 – Andes of W Argentina (San Juan S to SW Chubut and recently found in NW Santa Cruz#R) and adjacent Chile (S to Santiago).
