Range Description: This species occurs in  Venezuela and Colombia. In Venezuela, the species is know from the Cordillera de la Costa and the Cordillera de Mérida at elevations from 2,100 to 4,000 m (Handley 1976, Hershkovitz 1992).

Population [top]

Population: Paucity of specimens in collections suggest that the species is rare, probably due to low population densities.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology:

This species is found in savannah edge habitats, deciduous forest, humid evergreen forest, and cloud forest (Handley 1976, Hershkovitz 1992). It is associated with humid environments, frequently using the ecotone between forest and grasslands, mainly in riparian forest.  There are records from coffee plantations in Colombia (Hershkovitz 1992). Although there are not published studies about the ecology and natural history of the species, and there are few specimens in natural history museums and collections, most of the available speciems were captured on trees, suggesting that the species might be arboreal.

Systems: Terrestrial

Threats [top]

Major Threat(s): There is some threat from habitat loss, though not as severe since it uses secondary habitats.

Conservation Actions [top]

Conservation Actions: This species is found in several protected areas.
