Myotis yumanensis (Chiroptera: Vespertilionidae)

Abstract

Myotis yumanensis (Allen, 1864) is a vespertilionid bat commonly called the Yuma myotis. The species exhibits considerable geographic variation in coloration and size. It is 1 of about 100 species of Myotis worldwide and 1 of 17 species of Myotis in the United States. Although common throughout western North America generally at low elevations in desert or semidesert habitats, it is absent from the Great Basin. It is not of special conservation status, but protection of habitat especially along stream corridors is a concern.
