Mimon crenulatum 

 Striped Spear-nosed Bat 



Striped spear-nosed bats are found from Chiapas and the Yucatan Peninsula, 

 Mexico, to Brazil (Fig. 30). The subspecies Mimon crenulatum keenani is found 

 throughout Central America. 



Primarily an inhabitant of forested areas, this species also is known from banana 

 groves (Gardner et al. 1970). Roosts have been found in hollow trees and buildings 

 (Goodwin and Greenhall 1961). Apparently this species is known to eat only in- 

 sects (Gardner 1977). Reproductive data are too few to speculate on the cycle, 

 but pregnant females are known from Costa Rica at the beginning of the rainy season 

 (Wilson 1979). 



Striped spear-nosed bats first were reported from Costa Rica by Gardner et al. 

 (1970) by four specimens from Cariari. LaVal (1977) took 10 individuals in bat 

 traps in primary forest. We obtained one species of bat fly, Basilia tiptoni (1 male, 

 1 female), from M. crenulatum at La Selva. 



Specimen examined (1)— Finca La Selva, 3 km S of Puerto Viejo, 70 m 

 [1 male, MSB]. 



Additional record (1)— 2.5 km SE of Puerto Viejo [1 female, TCWC].
