Micronycteris schmidtorum 

 Schmidt's Large-eared Bat 



Schmidt's large-eared bat, a monotypic species, ranges from Cozumel Island, 

 Mexico, south to Venezuela (Fig. 28). Information on natural history is scanty. 

 Handley's (1976) Venezuelan collection includes specimens from a variety of habitat 

 types. He also reported individuals roosting in tree holes, and they have been taken 

 from hollow trees in Costa Rica (Starrett and Casebeer 1968). This species is in- 

 sectivorous, but Gardner (1977) also suggested that individuals may take fruit on 

 occasion. Nothing is known about the reproductive cycle. 



Starrett and Casebeer (1968) reported the first Costa Rican specimens from 

 Guanacaste Province. Mares and Wilson (1971) reported the first La Selva record. 

 Our single specimen from Braulio Carrillo was netted in primary forest at 300 m. 



An adult male bat fly, Trichobius sp., was collected from M. schmidtorum. 



Specimens examined (2)— 7.3 mi SE of Puerto Viejo [1 female, TTU]; 1 1 km S, 

 4.5 km W of Puerto Viejo, 300 m [1 male, USNM].
