Remarks: Chiroderma jesupi J. A. Allen (1900), known only by 

 the type specimen from northern Colombia, was described as a small 

 species. The type is a juvenile with phalangeal epiphyses not ossified. 

 It is the same as the bat subsequently described as C. isthmicum by 

 Miller (1912), and it is conspecific with Chiroderma villosum Peters, 

 type locality Brazil (not Venezuela as stated by Cabrera, 1958, p. 85). 

 The valid species of the genus Chiroderma are thus as follows : 



Chiroderma doriae Thomas: type locality, Minas Gerais, Brazil {dor sale 



Lund and villosum Dobson are synonyms). 

 Chiroderma gorgasi Handley: type locality, Tacarcuna Village, Darien, 



Panama. 

 Chiroderma salvini Dobson: type locality, Costa Rica. 

 Chiroderma trinitatum Goodwin: type locality, Cumaca, Trinidad. 

 Chiroderma villosum villosum Peters: type locality, Brazil. 

 Chiroderma villosum jesupi J. A. Allen: type locality, Cacagualito, Santa 



Marta, Colombia (isthmicum Miller is a synonym).
