First record of disk-footed bat (Chiroptera, Vespertilionidae) from China and resolution of phylogenetic position of the genus.

The disk-footed bat (Osgood, 1932) is a rare species in Southeast Asia. During two chiropteran surveys in the summer of 1981 and 2019, eight and three small -like bats with distinct disk-like hindfeet were collected from Yunnan Province, China, respectively. External, craniodental, and phylogenetic evidence confirmed these specimens as , representing a new genus in China. The complete mitochondrial genome consistently showed robust support for as a basal lineage within Myotinae. The coding patterns and characteristics of its mitochondrial genome were similar to that of other published genomes from . The echolocation signals of the newly collected individuals were analyzed. The potential distribution range of in Southeast Asia inferred using the MaxEnt model indicated its potential occurrence along the southern border region of Yunnan, China.
