The tragus is tapered with a blunt tip and is half as long as the ear.

The fur is fine, long and woolly and is greyish-brown dorsally and whitish or pale brown ventrally.

Two features which distinguish this bat from related species are the cylindrical penis in males and the short, Y-shaped penile bone.

It hunts in forests and the threats it faces include habitat loss and disturbance by tourism.

[1] This bat is the sole surviving endemic mammal found on the Island of Sardinia, the others all having become extinct since the arrival of humans some 8500 years ago.
