Recently described subspecies hernandezi differs markedly from nominate in habitat requirements, social organization and vocalizations, and possibly represents a separate species. Further study is required.
The following 2 subspecies are recognised:
apolinari Chapman, 1914 - Cundinamarca and Boyacá, in Colombian Andes.
hernandezi Stiles & Caycedo, 2002 - Sumapaz massif (south of Bogotá), in Cundinamarca (Colombia).
