The Ussurian tube-nosed bat (Murina ussuriensis) is a registered endangered species that has not been observed in South Korea since 1960. We were able to capture three individuals of M. ussuriensis between 2011 and 2013 at Sobaeksan National Park. The discovery of this species was the first time within 50 years. To collect basic data on the M. ussuriensis, we analyzed the external morphology and ultrasound characteristics of the captured bats. The results indicated that M. ussuriensis weigh approximately 5.2 g, which is less than that of a typical small bat such as Pipistrellus abramus. The bat's wing-type ratio was determined to be 1.22 and classified as a broad and short wingspan type. The bat uses FM signals for ultrasound with a peak frequency of 92 kHz. The M. ussuriensis seems to be a forest-dwelling bat that preys on insects by maneuvering expertly within the complex mazelike structure of forests. In the future, further research on the hibernation and foraging sites of the bats is necessary to protect and monitor the species.
