The distribution of the species is disjunct and very poorly known and is thus difficult to evaluate. It is seldom recorded although relatively widely distributed, is tolerant of a broad range of habitats and has a presumed large population, however, the southern population is likely to be severely threatened by loss of habitat. Further taxonomic revision is necessary, after which the status of the Atlantic Forest populations should be reevaluated.
|Previously published Red List assessments:|
|Range Description:||Patchily distributed in Central, and South America - and occurs in two disjunct populations. The northern area of occupancy occurs from Nayarit and Veracruz, Mexico, south through Central America to Peru, Colombia, Ecuador, French Guiana, Suriname, Venezuela, and Trinidad. A second area of occupancy occurs in southeast Brazil around Sao Paulo and Parana. It prefers low elevations, below 800 m (Reid, 1997; Eisenberg and Redford, 1999).|
In Venezuela know up to 1,100 m (Lew pers. comm.). Known from one yet unpublished point in Bolivia (Aguirre pers. comm.) (Aguirre and Tennan pers. comm.). Occurs in Panama (Samudio pers. comm.).

|Population:||This seems to be a very rare species throughout its range. Not common and local (Reid, 1997). Gleaning insectivore - sampling bias may underestimate populations.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Poorly known. Found in evergreen and deciduous lowland forest. Roosts in hollow trees and caves in groups of up to 75, it is capable of tolerating other species (Goodwin and Greenhall, 1961). Occasionally caught in mist nets or harp traps set over streams (Reid, 1997). These bats feed on large insects and occasionally fruit; they forage by gleaning large insects such as cockroaches, dragonflies, and katydids from the vegetation or ground, and they carry their prey back to a feeding roost before eating (Emmons and Feer, 1997). This is a rare and poorly known species. Occurs in moist tropical forests and also know from secondary forests nearby (Ochoa pers. comm.)|
|Major Threat(s):||Associated with caves and karstic habitats, the southern disjunct population is severely threatened by habitat loss.|
|Conservation Actions:||Conservation of caves and karstic regions. The species occurs in a number of protected areas throughout its range.|
