Chiroderma salvini 

 Salvin's White-lined Bat 



Salvin's white-lined bats are found from Chihuahua, Mexico, south through 

 Central America to Peru and Bolivia (Fig. 50). Only the nominate subspecies, 

 Chiroderma salvini salvini, is known to occur in Costa Rica, although Hall's (1981) 

 distribution map suggests that C. s. scopaeum may be found in Guanacaste. 



This species is found in forested regions, usually at middle or high elevations. 

 They are frugivorous, but details of the food habits are lacking. The reproductive 

 pattern is likely bimodal polyestry (Wilson 1979). Roosting sites are unknown. 



Dobson (1878) described C. salvini from a specimen collected in Costa Rica 

 by O. Salvin. White-lined bats are also known from near San Vito de Java (Wilson 

 1983a). Our specimen from 680 m in Parque Nacional Braulio Carrillo is the first 

 record for the northeastern Caribbean slopes. It was a pregnant female, netted over 

 a small stream crossing a pasture area. 



Specimen examined ( 1 )— 1 km S , 1 1 . 5 km E of San Miguel , 680 m [ 1 female , 

 USNM].
