This species is known from two localities in the Cordillera Oriental: La Cueva de las Moyas and the Páramo de Cruz Verde, Cundinamarca Department, Colombia, between 3,030–3,300 m asl. There is no suitable habitat between known localities. Its extent of occurrence (EOO) is 157 km2, its AOO is estimated as 8 km2, and it occurs in two threat-defined locations in two different páramos separated by grazing for cattle and cultivated lands.
Habitat and Ecology
This species occurs in streams within caves and crevices. Breeding and larval development takes place in streams.
This species was last seen in 1996. Three visits to the type locality and other attempts to find the species have failed to turn up this species and it is likely that it has declined severely due to complete habitat alteration (Colombia Amphibian Red List Assessment Workshop 2016). Due to the lack of suitable habitat between the two known sites, no dispersal is thought to occur between them, making the population severely fragmented.
It is threatened by habitat loss due to conversion to timber forestry and water pollution caused by urban runoff.
The species is not known to occur in any protected areas.
Surveys are needed to determine the current population status of the species.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered its area of occupancy (AOO) is approximately 8 km2, its population is severely fragmented, and there is continuing decline in the extent and quality of its habitat.
