Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Miller, B., Reid, F., Arroyo-Cabrales, J., Cuarón, A.D. & de Grammont, P.C.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Listed as Least Concern because it is widely distributed and unlikely to be declining at a rate which would qualify the species for inclusion in the threat categories.

Geographic Range [top]

Range Description: Central, and South America. This species is distributed from Costa Rica (LaVal and Rodriguez-H, 2002) south to Amazonian Brazil, Guianas, Suriname, Bolivia, Ecuador, and Peru; Trinidad (Simmons 2005). In Venezuela, it occurs at low elevations, below 1,000 m (Handley, 1976).

Population [top]

Population: Widely distributed. The species seems to be relatively uncommon but populations poorly understood and may be under represented in studies due to sampling bias. Just two records in Costa Rica (LaVal and Rodriguez-H, 2002).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Poorly known. In Venezuela it prefers moist habitats and multistratal evergreen tropical forest (Handley, 1976) and occurs in open areas (Reid, 1997). The type specimen from Trinidad was caught in a well-lit cave (Goodwin and Greenhal, 1961). It probably travels in the canopy or subcanopy, as it is seldom caught in nets set at understory level (Reid, 1997).
Systems: Terrestrial

Threats [top]

Major Threat(s): Habitat loss in some parts of the range, although this is not a major threat.

Conservation Actions [top]

Conservation Actions: Reduce loss of forest habitat. Found in protected areas.
