Subspecies
Forms a superspecies with Great Antpitta (Grallaria excelsa). Possibly conspecific, or possibly only subspecies lehmanni may be better placed with Great Antpitta (Grallaria excelsa). Or, conversely, subspecies hylodroma may deserve full species rank.

The following 3 subspecies are recognised:

  • lehmanni Wetmore, 1945   -  South-western Colombia at head of Magdalena Valley.
  • hylodroma Wetmore, 1945   -  South-western Colombia (Nariño) and Pacific slope of Andes in Ecuador (Pichincha, Cotopaxi).
  • gigantea Lawrence, 1866   -  Eastern slope of Andes of Ecuador (eastern Carchi and Napo south to Volcán Tungurahua).


Similar Species
