The Sardinian long-eared bat (Plecotus sardus) is a critically-endangered species of bat endemic to Sardinia, Italy.
This species was discovered in 2002 in the caves of central Sardinia, the type locality being a cave in Lanaitto's Valley in the Oliena District. [2] It appears to be closely related to Plecotus auritus and Plecotus macrobullaris . [2] It was identified as a new species by a study clearly showing divergence from other Plecotus species in its mitochondrial 16S rRNA gene. [3]
P. sardus is a small bat with a head-and-body length of about 45 mm (1.8 in), ears of about 38 mm (1.5 in) and a weight of up to 9 g (0.32 oz). The snout is cone-shaped with a fleshy knob on the chin. The ears are oval and joined above the forehead by a fine membrane. The tragus is tapered with a blunt tip and is half as long as the ear. The wing membranes are attached to the rear part of the base of the fifth toe. The tail is long and extends a short way beyond the interfemoral membrane. The fur is fine, long and woolly and is greyish-brown dorsally and whitish or pale brown ventrally. The wing membranes are brown. Two features which distinguish this bat from related species are the cylindrical penis in males and the short, Y-shaped penile bone. [3]
The Sardinian long-eared bat was first identified in 2002 and is only known from three caves where it roosts. Two of these are in the Gennargentu National Park and one near the coast. It hunts in forests and the threats it faces include habitat loss and disturbance by tourism. With a small total population and a decreasing population trend, the International Union for Conservation of Nature lists it as being a "critically endangered species". [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. [4]
Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus Vespertilio, which takes its name from a word for bat, vespertilio, derived from the Latin term vesper meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds".
Plecotus is a genus of vesper bat, commonly called long-eared bats. They are found throughout Eurasia and northern Africa. Many species in the genus have only been described and recognized in recent years.
The Alpine long-eared bat or mountain long-eared bat is a species of long-eared bat. It was originally described from Switzerland and Austria as a species intermediate between the brown long-eared bat and the grey long-eared bat in 1965. It was later described in 2002, from France and Austria, respectively. Despite its name, this species is not restricted to the Alps, being found in Croatia, Bosnia and Herzegovina and elsewhere. It differs from other European long-eared bats, such as the brown long-eared bat, by its white underparts.
Bokermann's nectar bat is a bat species from South America. It is endemic to Brazil. It feeds on nectar, and is listed as an endangered species.
The desert long-eared bat is a species of vesper bat found in North Africa and the Middle East.
Christie's long-eared bat, also known as the Egyptian long-eared bat, Christie's big-eared bat, or gray long-eared bat, is a species of vesper bat in the family Vespertilionidae. It is known from North Africa and the Middle East. Its natural habitats are subtropical or tropical dry shrubland, rocky areas, and hot deserts.
The Canary long-eared bat, also known as the Canary big-eared bat or Tenerife long-eared bat, is a species of vesper bat endemic to the Canary Islands. According to the IUCN, it is critically endangered. It feeds mainly on moths. Roosting sites include caves, lava tubes and abandoned buildings.
The blunt-eared bat or Peruvian crevice-dwelling bat is a species of bat in the family Molossidae. It is monotypic within the genus Tomopeas and subfamily Tomopeatinae. It is endemic to Peru, where it is considered critically endangered. It is threatened by habitat loss.
The Japanese long-eared bat is a species of vesper bat endemic to Japan, where it is found in Hokkaido, Honshu and Shikoku. It has distinctive, long ears, hence its Japanese name, the 'rabbit bat'. Formerly included as a subspecies of the European bat Plecotus auritus, genetic studies now indicate Plecotus sacrimontis is a separate species.
The Annamit myotis is a species of mouse-eared bat in the family Vespertilionidae, described in 2001, and indigenous to the Minh Hóa Districton the northern coast of Vietnam. Following its description, investigators succeeded in locating M. annamiticus only in Phong Nha-Kẻ Bàng National Park, and the data regarding the distribution, population, and range of the species is otherwise inadequate to determine its conservation requirements. However it is protected by Phong Nha-Kẻ Bàng National Park.
The southern big-eared brown bat is a species of bat from the family Vespertilionidae. Although current taxonomy treats the southern big-eared brown bat as a separate species, it is often treated as a subspecies of the small big-eared brown bat. It lives in the forests of southern Argentina and Chile; though the population of the bat in the southern part of its habitat is low, there are no major concerns to justify anything lower than a Least Concern rating in the IUCN Red List.
Rhagamys is an extinct genus of rodents in the subfamily Murinae, the Old World mice and rats. The genus was established by the Swiss zoologist Charles Immanuel Forsyth Major to accommodate Rhagamys orthodon, which is the only species in the genus. It was endemic to the Mediterranean islands of Corsica and Sardinia, descending from Rhagapodemus, which had colonised the islands around 3.6 million years ago. Its closest living relatives are of the genus Apodemus, which includes the field and wood mice.
The New Caledonian long-eared bat is a vesper bat found in New Caledonia. They are only recorded at Mount Koghis, near Nouméa, and the population is decreasing.
Thomas's big-eared brown bat is a species of vesper bat found in South America.
Nyctophilus major, referred to as a western long-eared bat, is a species found in forests and woodlands of Southwest Australia.
Plecotini is a tribe of bats in the family Vespertilionidae. It contains several genera found throughout the Northern Hemisphere, in Eurasia, North Africa, and North America. Several genera in this tribe are known as big-eared bats or long-eared bats. It also contains the spotted bat and barbastelles.
Kozlov's long-eared bat is a species of vesper bat in the family Vespertilionidae. It is found in southern Mongolia and adjacent parts of China.
Ward's long-eared bat is a species of vesper bat in the family Vespertilionidae. It is found in mountainous regions of South Asia and adjoining regions.
