Dayak roundleaf bat

The Dayak roundleaf bat, Hipposideros dyacorum, also known as the least roundleaf bat, is a small leaf-nosed bat endemic to Indonesia and Malaysia, on the island of Borneo. Oldfield Thomas described it in 1902 from a specimen that Charles Hose collected on Mount Mulu in Sarawak, and he misspelled the genus as Hipposiderus in the original name. The forearm is 40 to 42 millimetres and individuals weigh 6 to 10 grams. The Mammal Diversity Database also lists Brunei and Thailand in its range, places it in the Indomalayan realm and records an IUCN status of Least Concern. The English Wikipedia article gives little on its ecology or behaviour.
