captured 21 specimens at La Selva. One individual was netted over a small stream 

 in primary forest. 



Specimens examined (9)— Puerto Viejo, Rio Sarapiqui, 300 ft [2 males, 

 1 female, UMMZ]; Finca La Selva, 3 km S of Puerto Viejo, 70 m [1 male, KU; 

 1 male, LACM; 1 male, 1 female, MSB]; 5.7 mi S of Puerto Viejo [1 female,

Micronycteris minuta 

 Gervais' Large-eared Bat 



Gervais' large-eared bat, a monotypic species, is known from Nicaragua to 

 southern Brazil (Fig. 26). It is primarily an inhabitant of forested regions, but speci- 

 mens also are known from agricultural areas (Williams and Genoways 1980). Roosts 

 have been reported in hollow trees, caves, and mines (Sanborn 1949). These bats 

 feed on insects and plant material (Fleming et al. 1972). Reproduction occurs at the 

 beginning of the rainy season, but the complete cycle is unknown (Wilson 1979). 



The first Costa Rican records were reported by Gardner et al. (1970) from 

 Cartago, Guanacaste, and San Jose Provinces. LaVal and Fitch (1977) reported 

 one from La Selva. We caught and released a second individual at La Selva in 

 1973. Apparently no individuals of Micronycteris minuta from La Selva have been 

 preserved.
