Mehely's horseshoe bat (Rhinolophus mehelyi ) is a species of insectivorous bat in the family Rhinolophidae found in Southern Europe and parts of the Middle East. It is distributed in a narrow band around the Mediterranean Sea from North-Western Africa across Portugal, Spain, the Balearics, southern France, Sardinia, Sicily and the Balkan Peninsula to Asia Minor.
The bat is medium-sized for a member of the genus Rhinolophus, with pale lips and grey-brown ears and flight membranes. The fur is relatively thick, with the base of hairs grey-white. Ventral fur is almost white, while dorsal fur is grey-brown; the line between the dorsal and ventral sides is relatively sharp.
The bat is cave-dwelling, preferring areas of limestone with nearby water. It has been known to roost in caves with other horseshoe bats such as Rhinolophus hipposideros , as well as Myotis myotis and Miniopterus schreibersi . It prefers to roost in warmer cave cavities, such as those found in the Cova de Sa Guitarreta (Mallorca), while hanging free on the cave roof.
