Lesser mouse-eared bat

The little mouse ear is very similar to the slightly larger big mouse ear. It reaches a head-trunk length of 62 to 71 (rarely from 54, or to 76) millimeters and a weight of 15 to 28 grams. The span is 380 to 400 millimeters, the Condbylobas length 17.2 to 18.5 millimeters. The tail is 53 to 59 (maximum 60) millimeters long, the ears 19.8 to 23.5 (maximum 26) and the forearm 52.5 to 59 (maximum 62.5) millimeters. The ears are narrow and shorter than those of the Great Mouse Ear. The front edge of the ears is not bent so much backwards, and the ears taper sharper. The tragus is narrower at the base, lancet-shaped and is almost half as long as the ear. The outer edge of the ear has 5 to 6 transverse folds. The muzzle is narrower and sharper compared to the Great Long-eared, which makes it look longer. The coat is short and the hair base is dark gray. The top is gray with a brownish tinge, while the underside is greyish white. Ears, muzzle and flies are light gray-brown. The tragus is bright yellowish white. The arms of the arms begin at the base of the toes. The spur is about half as long as the tail flight skin and has a narrow skin hem. Animals found in Switzerland usually have a bright spot between the ears. Other color staining abnormalities are unknown. A cognitive examination of three female animals from Iran found a chromosome number of 2n = 44.
