|Reviewer/s:||Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)|
This species is listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.
|Range Description:||This species is found in Central and South America. This bat is known from Mexico, northwest Honduras, Costa Rica, Panama, Venezuela, Guyana, Surinam, French Guiana, Peru, Ecuador, Bolivia, and Brazil (Simmons 2005). It occurs at elevations 45 m in French Guiana (Simmons and Voss, 1998), 155 m in Venezuela (Eisenberg, 1989; Handley, 1976), and at 320 m in Peru (Graham and Barkley, 1984). In Belize is known from colections (Reid pers. comm.).|

|Population:||The species is rarely encountered because it is difficult to capture due to their high flying and roosting behaviors (Emmons and Feer, 1997). Need acoustic surveys as for all molossids (Miller pers. comm.). Rare in Mexico.|
|Habitat and Ecology:||E. hansae flies in the upper levels of the canopy (Fenton, 1972); occurs in tropical forests off coastal areas (Alvarez-Castañeda and Alvarez, 1991); in the eastern Brazilian highlands, and coast and in the Amazon Basin and Atlantic Forest biomes (Koopman, 1982; da Fonseca et al., 1996). In Venezuela, it has been observed over ponds, large clearings, and evergreen forests; roosting inside a cavity located in a dead standing tree in a large lagoon (Handley, 1976). In Peru, E. hansae flew over a small river bordered by tall, tropical, lowland forest in hilly terrain (Graham and Barkley, 1984). In Bolivia, this bat occurred in a savanna area near the edge of a forest (Ibañez and Ochoa, 1989). The stomach of a specimen from Bolivia contained Orthoptera (Anderson, 1997).|
|Major Threat(s):||There are no major threats throughout its range.|
|Conservation Actions:||Occurs in protected areas throughout the range.|
