From the IUCN Red List Species Account:


Range Description

This species is known from the central páramos in Tolima, Caldas and Quindio Departments, on the eastern flank of the central Andes, in Colombia, between 2,700 and 3,700 m asl. Its extent of occurrence (EOO) is estimated to be 2,340 km²

Habitat and Ecology

The species occurs on leaf-litter and rocks on the ground in Andean forests and páramos, and has not been recorded from anthropogenic habitats. It is a direct developing species.


It is not a common species. Current information on the population's status is lacking. There has been little sampling effort within the species' range; however, it was recently recorded in 2013 in Reserva Robert Gilesi (O. Cortés pers comm. August 2014). It is found only in pristine forest and páramo habitat, which has been fragmented by forest loss and land use. Habitat fragmentation has likely reduced connectivity among remnant subpopulations, rendering the population severely fragmented (O. Cortés pers. comm. August 2014).

Population Trend


Major Threats

It is threatened by habitat loss and fragmentation, mainly due to the expansion of agriculture, and pollution from the fumigation of illegal crops. Climate change is also a potential threat to this high-elevation species, although this requires verification.

Conservation Actions

Its range includes several protected areas, including Reserva Robert Gilesi, Reserva Loros Andinos, and Reserva Roncesvalles,
