Cox's roundleaf bat

Cox's roundleaf bat, Hipposideros coxi, also called Cox's leaf-nosed bat, is endemic to Borneo, where all confirmed records are from Sarawak in Malaysia, with Kalimantan in Indonesia a possible further locality. Robert Shelford described it in 1901 from a specimen collected on Mount Penrisen by E. A. W. Cox, who gave it its name. It is a medium-sized member of its genus, distinguished among Bornean hipposiderids by a particularly large nose leaf that covers the whole muzzle and by large ears, with dark brown fur and a forearm of 50.6 to 56 millimetres. It roosts by day in caves in colonies of twenty or fewer and eats insects of at least seven orders. The IUCN lists it as Endangered because its area of occupancy is under 500 square kilometres and it is threatened by cave disturbance, nest harvesting, mining and quarrying.
