This species was previously only known from two sites 50 km apart, in Municipio Pajarito and Municipio Garagoa in Boyacá Department, on the Cordillera Oriental of the Colombian Andes, between 1,600–1,750 m asl. Its geographical distribution is now wider and includes Acacias, Las Salinas (Meta department; vouchers deposited in ICN-UNAL Lynch and Carranza 1977, 1998) and Chamesa (Casanare department; Acosta and Alfaro-Bejarano 2011 Biodiversidad del Departamento del Casanare). Its EOO is 4,622 km2 and its range represents four threat-defined locations.
Habitat and Ecology
This species occurs on vegetation near streams in cloud forest. It also occurs in secondary forest. Eggs are laid on the vegetation, and the larvae develop in the water. It is highly tolerant to stream pollution (sewage vertments).
This is a common species inhabiting polluted streams near a village (Santa María - Boyacá department): these observations are based upon semestral field courses since 2015 (N. Urbina pers. comm. August 2016).
The main threat to this species is habitat loss caused by the expansion of cattle ranching and the planting of illegal crops. Recent surveys in Santa Maria (Boyacá) revealed that this species tolerates polluted water (Nicolas Urbina pers. comm. 2016).
Conservation ActionsThis species has not been recorded in any protected areas.
Habitat protection is a much-needed conservation action for this species.
More information is needed on this species' distribution, population status, ecology, and threats.
Red List Status
Listed as Endangered, because its extent of occurrence (EOO) is 4,622 km2, all individuals occur in four threat-defined locations, and there is continuing decline in the extent and quality of its habitat on the Eastern Cordillera of the Colombian Andes.
