Suggested to be sister to G. gigantea#R; later proposal that G. varia is sister to present species#R#R was based on studies that did not include gigantea in samples. Birds from Cordillera de Cutucú (SE Ecuador), though tentatively included with similarly plumaged Peruvian race canicauda, are isolated from nearest population of this race by an area occupied by nominate, and probably represent an independent lineage; further study needed. Authorship and date of species name recently corrected#R. Two subspecies recognized.

Subspecies and Distribution
  • G. s. squamigera Lafresnaye, 1842 – Andes from W Venezuela (Trujillo S to Táchira) and all three ranges of Colombia S to S Ecuador.
  • G. s. canicauda Chapman, 1926 – SE Ecuador (Cordillera de Cutucú); also Peru in Cajamarca (Chira) and from S & E of R Marañón to C Bolivia (Cochabamba).
