Geographic Range [top]

Range Description: This bat occurs in the northern Amazon Basin (Koopman, 1982). It is known only from Brazil, Venezuela, Guyana, and Surinam (Eger, 1977; Koopman, 1994; Reid et al., 2000; Sanchez et al. 1992). It is present at an elevation below 500 m (Sanchez et al. 1992; Reid et al. 2000).
Countries occurrence:
Guyana; Suriname; Venezuela, Bolivarian Republic of

Population [top]

Population: This is one of the rarest Neotropical bats; know from a few individuals taken from less than ten localities in humid lowland areas. It is probably declining through habitat loss. The species is rarely encountered because it is difficult to capture due to its high flying and roosting behaviours (Emmons and Feer, 1997).
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: This species is poorly known. In Venezuela, a female was present in a 15-year-old pine (Pinus caribaea) plantation; original vegetation at this locality corresponds to grass (Trachipoqum) savannas, in association with swamps dominated by the palmMauritia flexuosa, gallery forests, and swampy evergreen forests (Sanchez et al., 1992). In Ecuador, this bat was collected in the tropical evergreen forest (Reid et al. 2000). It is insectivorous; may feed on large insects likes other species of Eumops.
Systems: Terrestrial

Major Threat(s): Habitat loss.
