Semon's roundleaf bat

Semon's roundleaf bat, Hipposideros semoni, also called Semon's leaf-nosed bat, is found in northern Queensland in Australia and in Papua New Guinea. Paul Matschie described it in 1903 from a specimen brought back by Richard Semon's research voyage, and the species is named for him. The head and body are 40 to 50 millimetres long, the wingspan about 320 millimetres and the weight 6 to 10 grams, with long narrow ears and smoky gray fur. It is nocturnal and roosts by day singly or in small colonies in abandoned mines, caves, hollow trees and rock fissures, and it hunts spiders, beetles and moths close to the ground. The IUCN lists it as Least Concern, but it is endangered in Queensland and vulnerable under national law.
