Vietnam leaf-nosed bat

Vietnam leaf-nosed bat(Paracoelops megalotis)This bat species is known from a single specimen. It is characterised by its exceptionally large ears, which are separate and rounded at the top. The only specimen was collected from a very small area of forest which is now being cleared, and the species has not been reported since its description more than 60 years ago. Many researchers fear that this little bat may now be extinct.

Description

Size: Body length: 45 mmForearm length: 42 mmEar length: 30 mm Weight:7 g This bat's ears are exceptionally large, and separate and rounded at the top. The muzzle has an elaborate leaf-like outgrowth of skin, which is thought to serve some sensory function. The top of the head is bright golden-yellow, and the ears are pale brown. The underparts are light beige.

Ecology

Nothing is known about the ecology of this species as it has never been studied. Like other small bats it is probably nocturnal, and catches insects in flight using echolocation, which involves ultrasonic sounds being emitted through the mouth or nose. and coming in through the anus

Habitat

Other leaf-nosed bats inhabit forests and woodlands. Aquatic habitats are favoured as feeding areas as they attract a wide variety of insects.

Distribution

Vietnam. Possibly also Laos and Cambodia.

Threats

The species is known only from a very small area of declining habitat. It has not been reported since its description more than 60 years ago, and many researchers fear that it may now be extinct.
