This species occurs in the northern Cordillera Oriental in the departments of Norte de Santander and Santander, Colombia, and nearby at Macizo de Tamá in Venezuela. Its altitudinal range is 1,900-3,550m asl.
Habitat and Ecology
It is a cloud forest species, also living in páramo grassland and sub-páramo bushland areas. Its ability to adapt to modified habitats is unknown. It is usually found at night on low vegetation; during the day it hides under rocks, logs or among vegetation. It is presumed to be a direct developing species.
It is common in Colombia, but there is little information on its population status in Venezuela.
The major threats are deforestation for agricultural development (including cultivation of illegal crops), logging, and human settlement, and pollution resulting from the spraying of illegal crops. Fire might also be a threat. However, it has a broad altitudinal range, and overall its habitats are probably not seriously threatened.
The Venezuelan populations are within Parque Nacional El Tamá and the Estación Demonstrativo El Rasgon. Its occurrence in protected areas in Colombia is unclear.
Red List Status
Near Threatened (NT)
Listed as Near Threatened, because although the species is abundant within its small range, and may not be declining, its extent of occurrence is less than 5,000 km2, thus making the species close to qualifying for Vulnerable.
