Wollaston's roundleaf bat

Wollaston's roundleaf bat, Hipposideros wollastoni, is a leaf-nosed bat known only from the island of New Guinea, in West Papua in Indonesia and in Papua New Guinea. Oldfield Thomas described it in 1913 from a specimen collected on one of Sandy Wollaston's expeditions, and the species is named for him. Thomas found it similar to the Fly River roundleaf bat but noted a peculiar duplication behind the posterior nose leaf. The forearm is about 44 millimetres, the head and body 45 millimetres and the tail 27 millimetres. It has been found from 30 to 2,440 metres above sea level in montane forests, oak forests and secondary forests. The IUCN lists it as Least Concern, its lowest conservation priority.
