Mediterranean horseshoe bats are medium-sized, weighing betwen 8 and 17.5 g. Total length of these animals is 65 to 88 mm, and wingspan is between 300 and 320 mm. Females are often larger than males.
The horseshoe and lips of the bat are light brown, and the ears and wing membranes are light gray. The fur of this bat is sparse, becoming light gray toward the base. The back is a gray-brown, with a light reddish or pinkish tint. The underside is gray-white to a yellowish-white. The boundary between dorsal and ventral color is indistinct. Darker hairs may be present around the eyes.
The wings of the bat are broad (suggesting life in the forest), with the second phalanx of the fourth finger having more than twice the length of the first. When at rest, the third to fifth fingers are bent 180º at the joint between the first and second phalanges. Because of this, these bats cannot be completely wrapped by their wing membranes.
The species is nasal emitting, with an upper saddle process pointed and slightly curved downward. The lower saddle process is rounded when viewed from below, and is noticably shorter than the upper saddle process.
