This species is known from cloud forest in the municipalities of Pensilvania and Samaná, in Caldas Department, and from the municipalities of Guatepé and Anorí, in Antioquia Department, on the eastern flank of the Cordillera Central, Colombia. It has been recorded between 1,800–2,000 m asl. Its extent of occurrence (EOO) is 3,606 km2.
Habitat and Ecology
This species is restricted to primary forest and is not associated with streams. It is very small (at most 23 mm long) and is very sensitive to any variation in humidity. It is not tolerant of any habitat disturbance. It breeds by direct development.
It is not a common species. Most of the population is in small subpopulations with no exchange of individuals among them. The population is therefore considered as severely fragmented and due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
The main threat to this species is habitat loss due to agriculture development and livestock.
This species is present in Reserva Forestal La Forzosa and Parque Nacional Natural Selvas de Florencia.
Research is needed to better determine its distribution, population size and trends and the threats that may be affecting it.
Red List Status
Listed as Endangered because its extent of occurrence (EOO) is 3,606 km2, its population is severely fragmented, and there is continuing decline in the extent and quality of habitat due to agricultural and livestock activities.
