Until recently considered conspecific with U. saturatior (which see). Proposed race hallinani (N Chile, NW Argentina) appears to represent clinal extreme of paleness at N end of range of hypoleuca. Three subspecies recognized.

Subspecies and Distribution
  • U. d. peruana J. T. Zimmer, 1954 – Andes of S Peru (Puno).
  • U. d. hypoleuca Reichenbach, 1853 – W Bolivia, C Chile (Antofagasta S to Maule) and W Argentina (Jujuy S to N Río Negro, E to Córdoba).
  • U. d. dumetaria I. Geoffroy Saint-Hilaire, 1832 – S Chile (Aisén, Magallanes) and C & S Argentina (Córdoba and Buenos Aires S to N Tierra del Fuego); S populations migrate to N Argentina and S Uruguay.
