Relationships
Myotis has historically been included in the subfamily Vespertilioninae, but was classified in its own subfamily, Myotinae, by Nancy Simmons in 1998. In her 2005 classification in Mammal Species of the World, Simmons listed the genera Cistugo and Lasionycteris in Myotinae in addition to Myotis itself. However, molecular data indicate that Cistugo is distantly related to all other Vespertilionidae, so that it was reclassified into its own family Cistugidae, and that Lasionycteris belongs in Vespertilioninae. Thus, Myotis is the only remaining genus within Myotinae.
