The Japanese long-eared bat ( Plecotus sacrimontis ) is a bat in the smooth-nosed family (Vespertilionidae), which occurs in Japan and on the southern Kuril Islands . This taxon was a long time as a subspecies of the brown long-eared bat ( Plecotus auritus ). In 2006 it was recognized as Art .

features

A specimen from the Kuril Islands had a head-to-body length of 56 mm, a tail length of 51 mm and a weight of 9.1 g. The forearm length was 43.5 mm and the ears were 38.2 mm long. Other individuals from the Kuril Islands attained a wingspan of 278 to 291 mm. According to the study, comparable measurements from Japan showed roughly the same results.

The Japanese long-eared bat is a medium-sized to large representative of the brown-colored long-eared bats ( auritis group). The body is covered with soft, dense and woolly fur, which is predominantly brown in color. It is characterized by a dark brown area on the muzzle and around the eyes that resembles a mask. The large ears and the membranes are thicker than those of closely related species. Various individuals have white hair in the area of ​​the external genitourinary system and in some specimens parts of the tail skin are covered with fur on the top. The species has large thumbs and curved pale yellow claws on all fingers and toes.

Distribution and way of life

The range of the Japanese long-eared ear includes almost all of the main islands of Japan with the exception of Kyūshū and Honshū's southwestern areas. Of Shikoku only isolated finds are documented. The species still occurs on Kunashir and Iturup . It lives in the hill country and in mountains at 700 to 1700 meters above sea level.

During the day the Japanese long-eared mostly rests in tree hollows. It can use caves, buildings, tunnels or similar hiding spots as a sleeping place. The bats hunt at night in various areas of the surrounding landscape, including urbanized areas.

status

No serious threats are known to the Japanese long-eared population. The species is listed as Least Concern by the IUCN .
