Pteropus pilosus Andersen, 1908:369

Large Palau flying(-)fox, Large Pelew flying(-)fox, Belau fruit bat



Taxonomy & Nomenclature



Conservation Status

Last record: 1874 or before

IUCN RedList status: Extinct


The reasons for the decline and extinction of this species are not understood, but it is likely that hunting by the natives contributed. Several surveys of the island fauna failed to locate this species in the 20th century (Mickelburgh et. al. 1992).



Palau Islands (=Pelew Islands = Belau), Caroline Islands, Micronesia






Only known from two specimens collected in 1874 or prior (Bonaccorso et. al. 2008), and now in the British Museum of Natural History (Mickleburgh et. al. 1992).
