New records of Myotis bakeri (Chiroptera: Vespertilionidae), and preliminary evidence of a new zoogeographic pattern

Abstract

Myotis bakeri is a Peruvian endemic bat with little information about its natural history and geographic distribution. Based on a revision of museum specimens, we report new records of M. bakeri extending its distribution range 143 km northwest and 98 km southeast. Also, the elevational range is extended to 1445 m. The current allopatric distribution of M. bakeri and M. atacamensis, and other bat species, suggests the existence of two unreported bat assemblages in the Peruvian western slope.
