Myotis blythii

Classification and Description

Myotis blythii, also known as Blyth's mouse-eared bat or small mouse ear, is a species of bat in the genus Myotis. It was first described by Robert Fisher Tomes in 1857.

The scientific name honors Edward Blyth, an English zoologist.

Physical Characteristics

Myotis blythii has a similar appearance to its larger cousin, the large mouse ear. The head-to-truncated length of this species ranges from 62 to 71 millimeters (rarely between 54 and 76 millimeters), with a weight of 15 to 28 grams. The wingspan is approximately 380 to 400 millimeters.

The condylobasal length is between 17.2 and 18.5 millimeters, while the tail measures 53 to 59 (maximum 60) millimeters in length. The ears are narrow and shorter than those of the Great Mouse Ear, with a maximum length of 26 millimeters. The front edge of the ears is not as curved backwards as other species, and they have a sharper shape.

The tragus is narrower at the base, lancet-shaped, and almost half as long as the ear. The outer edge of the ear has 5 to 6 tragi.
