The southern geographic range of Micronycteris sanborni (Chiroptera, Phyllostomidae)

The southern distribution of Micronycteris sanborni became controversial after the description of Micronycteris yatesi based on specimens formerly reported as M. sanborni in Bolivia. It raised doubts on the identity of the southernmost specimen of M. sanborni reported from Serra da Bodoquena, Brazil. We rechecked the identification of this specimen and report four new records of M. sanborni from Serra da Bodoquena. External and craniodental features of all five examined specimens fit the current M. sanborni diagnosis, supporting this region as the southern boundary of its geographic range in South America.
