|Red List Category & Criteria:||Least Concern ver 3.1|
This species is listed as Least Concern because there are no declines in habitat or population due to the fact that it is well protected by national parks.
|Previously published Red List assessments:|
|Range Description:||According to Percequillo et al. (2015), this species occurs on the forested slopes from northeastern Cordillera Oriental of Colombia in Boyacá department, through the Páramo de Tamá on the Colombian-Venezuelan border, to the northern portion of the Sierra de Mérida, in Trujillo state, Venezuela, and over an elevation range from 1,100 to 4,000 m. See Anderson and Raza (2010), who modeled the species’ climatic niche and potential distribution.|

|Population:||There is no information on populational parameters for this species.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||This is a poorly known species, that "inhabits the dense, cold, forested areas of the Páramo de Tamá, on the Venezuelan/Colombian border, where specimens have been taken in ground litter and under logs and roots" (from Percequillo et al. 2015). According to prior information on IUCN, it is a cloud forest specialist, nocturnal and omnivorous (Aguilera and Rivas pers. com.), and a "bioindicator of cloud forest conditions". It is terrestrial and solitary.|
