Subspecies
Plumage characteristics suggest most closely related to Common Miner (Geositta cunicularia). Separation of the two in conventional linear sequences is a result of overemphasis on bill morphology in traditional taxonomy. Some specimens from north-western Peru (Cajamarca) intermediate between nominate subspecies and kalimayae.
The following 2 subspecies are recognised:
kalimayae Krabbe, 1992 - Andes of central Ecuador (Cotopaxi).
tenuirostris (Lafresnaye, 1836) - Andes of Peru (Cajamarca south to Arequipa in west, and south from Huánuco on eastern slope), Bolivia and north-western Argentina (south to Tucumán; one record La Rioja).
