“Yenping, Fukien Province, China.”

Subgenus Myotis ; daubentonii species group. See M. daubentonii and M. longicaudatus . Myotis frater has only been confirmed from Taiwan and type locality in Fujian, China. All southern Chinese populations are tentatively retained under M. frater until additional research can be done. Monotypic.
