This species is known only from the vicinity of the type locality, El Estadero, in Caldas Department, Colombia, from 2,000m asl.
Habitat and Ecology
It is an inhabitant of the understorey of very wet primary forest, and it breeds by direct development with eggs laid on the ground. It has not been recorded outside primary forest, suggesting that it is very sensitive to habitat disturbance.
It is not thought to be a rare species, but it is a difficult and dangerous area in which to conduct survey work.
The main threat is habitat loss and destruction due to logging, agriculture and the planting of illegal crops.
The range of the species is not within any protected area., and there is an urgent need for the establishment of a protected area to safeguard the primary forest remaining at the type locality. Further survey work is needed to determine the population status of this species, and to determine if it occurs outside the vicinity of the type locality.
