Paracoelops megalotis
Known from a single specimens, a adult male collected in Vinh, Anam, Vietnam in 1945, and since then there hasent been any records and accorind to conservation specialists in the country it should be listed as extinct as there is no proof that it still exsist.

Paracoelops megalotis Dorst, 1947 COMMON NAMES. Dơi thùy tai to; Funnel-eared leafnosed bat; Воронко- ухий листонос. MATERIAL STUDIED. No specimens were studied. The diagnosis below follows Nowak (1994). IDENTIFICATION. A small leafnosed bat (weight ca. 7 g; forearm ca. 42 mm). Ears very large, approximately 2/3 of head and body length, widely rounded on top. Horseshoe surmounted by rounded supplementary leaf with radial striations. Tail is absent, while the interfemoral membrane is welldeveloped, supported by long calcars. Pelage in the single known specimen is long and thick, brown on back, light beige with yellow roots on the underparts, and bright yellow on the crown. Membranes dark brown. This species differs from Coelops frithii by the shape of noseleaf, remarkably larger ears and wide interfemoral membrane; from Aselliscus and small Hipposideros — by absent external tail. DISTRIBUTION AND COLLECTING SITES. Until now known only from the type locality in Vietnam (Vinh, Nghe An Province). COMMENTS ON NATURAL HISTORY. Natural history is unknown.

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. www.edgeofexistence.org/species/species_info.asp?id=15 |

Evolutionary Distinctiveness Horseshoe and Old World leaf bats are clearly closely related, and are usually placed together in a single family, the Rhinolophidae. Within this family they are separated into two subfamilies: the Hipposiderinae (horseshoe bats) and Rhinolophinae (Old World leaf-nosed bats). The Vietnam leaf-nosed bat belongs to the Hipposiderinae, which includes 81 species in nine genera (Hipposideros, Rhinonycteris, Coelops, Paracoelops, Triaenops, Cloeotis, Anthopx, Asellia, and Aselliscus). Some researchers argue that the horseshoe bats are sufficiently distinct from the Old World leaf-nosed bats to be placed in a completely separate family: the Hipposideridae. Either way, horseshoe bats are though to date back to at least the middle Eocene (some 45 million years ago). The Vietnam leaf-nosed bat is the sole representative of the genus Paracoelops. The fossil record of bats is very poor, and there are no fossils of Paracoelops. It is believed to be most closely related to the Asian genus Coelops, the African Cloeotis and the extinct Australian Archerops. Newly discovered fossils from the latter genus are estimated to be between 15 and 20 million years old. Description Size: Body length: 45 mm Forearm length: 42 mm Ear 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. 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. Population Estimate Unknown. Possibly extinct. Status Classified as Critically Endangered (CR B1+2c) on the 2006 IUCN Red List of Threatened Species. 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. www.edgeofexistence.org/species/species_info.asp?id=15 |

This species is now confirmed to be a synonym of Hipposideros pomona. Resolving a mammal mystery: the identity of Paracoelops megalotis (Chiroptera: Hipposideridae)Paracoelops has been regarded as monotypic and an endemic bat genus of Vietnam. In the original description of 1947, P. megalotis was characterised by its exceptionally large ears and well developed interfemoral membrane without a tail. The status of this taxon remained uncertain since the species and genus descriptions were based on the single, badly damaged holotype. Recently, we re-examined the holotype and found discrepancies between its features and those described in the diagnoses. Its measurements and characteristics are entirely identical to those of a small species of Hipposideros. Having compared its features with those of other hipposiderids, we show here that Paracoelops megalotis was incorrectly classified both in terms of genus and species and should be considered a synonym of Hipposideros pomona. www.mapress.com/zootaxa/2012/f/z03505p085f.pdf |
