Plumage characteristics suggest most closely related to G. cunicularia, and this is supported by genetic data#R#R; separation of the two in conventional linear sequences is a result of overemphasis on bill morphology in traditional taxonomy. Some specimens from NW Peru (Cajamarca) intermediate between nominate race and kalimayae. Two subspecies recognized.

Subspecies and Distribution
  • G. t. kalimayae Krabbe, 1992 – Andes of C Ecuador (Cotopaxi).
  • G. t. tenuirostris (Lafresnaye, 1836) – Andes of Peru (Cajamarca S to Arequipa in W, and S from Huánuco on E slope), Bolivia and NW Argentina (S to Tucumán; one record La Rioja).
