See G. squamigera (above). May be conspecific with G. excelsa, or perhaps only race lehmanni better placed with that species; conversely, race hylodroma may deserve full species rank. Vocal analysis reveals very similar songs, differing subtly in degree of acceleration#R. Three subspecies recognized.

Subspecies and Distribution
  • G. g. lehmanni Wetmore, 1945 – SW Colombia at head of Magdalena Valley; probably extinct.
  • G. g. hylodroma Wetmore, 1945 – SW Colombia (Nariño) and Pacific slope of Andes in Ecuador (Pichincha, Cotopaxi).
  • G. g. gigantea Lawrence, 1866 – E slope of Andes of Ecuador (E Carchi and Napo S to Volcán Tungurahua and Sangay National Park#R).
