A new species of Myotis from China with notes on the siligorensis species group (Chiroptera, Vespertilionidae).

On the basis of molecular and morphological studies of samples collected in China, a new Myotis species belonging to the siligorensis group is described, Myotis kalkoae Tiunov, Jiang, & Liu, sp. nov. The species rank of M. sowerbyi and M. alticraniatus was confirmed. All three taxa under consideration belong to different genetic lines and can be distinguished from each other and from other morphologically similar species based on the shape of their baculum and tragus. The difficulties of taxonomy within the M. siligorensis species group are discussed.
