Northern leaf-nosed bat

The northern leaf-nosed bat, Hipposideros stenotis, also called the narrow-eared roundleaf bat, is a small bat endemic to northern Australia. Oldfield Thomas described it in 1913 from a specimen taken by Knut Dahl at the Mary River, and the species name comes from Greek words for narrow and ear, after the narrowed ears he noted. The forearm is 42 to 46 millimetres, the head and body 40 to 46 millimetres, and the weight averages 5.5 grams. It is known from the Top End, the Kimberley, the Gulf Country west of Mount Isa and the Buccaneer Archipelago. It roosts in sandstone caves, boulder piles and abandoned mines, forages at night for flying insects, and is wary and rarely captured. The IUCN lists it as Vulnerable.
