A review of the mouse-eared bats (Chiroptera: Vespertilionidae: Myotis) from Vietnam with significant new records.

(Uploaded by Plazi for the Bat Literature Project) Eight species of mouse-eared bat (Myotis) have recently been collected in the Socialist Republic of Vietnam. Five of these (M. chinensis, M. ricketti, M. montivagus, M. ater and M. horsfieldii) are new to the country or little known; additional locality records are included for M. siligorensis, M. muricola and M. daubentonii. Diagnostic characters are reviewed for these and six further species of Myotis that have been previously recorded from the country. Data on national and world distributions, ecology and conservation status are included, as well as a key to species based on external, cranial and dental characters.
