Pachygenium muyscarum, a new species from Colombia, is described, illustrated, and aspects related to its distribution, ecology, conservation status, and relationships with morphologically similar species are discussed. This species is characterized by flowering without leaves, labellum 1.4–1.6 cm long, with the apex trilobulate and labellum nectar glands 0.2–0.4 cm long, subulate and uncinate. To date, this is the only species of the genus present in Colombia, being endemic to the subxerophytic enclaves of Cundinamarca.
