The eastern broad-nosed bat (Scotorepens orion) is a species of vesper bat. It is found only in Australia, east of the Great Dividing Range, from about Rockhampton to Melbourne, with s small isolated population on the Atherton Tablelands. It is a medium-sized bat, with forearm 32.4 to 38.8 mm. Its fur-colour is a rich dark brown on the back, with a more drab belly, not markedly bicoloured. It can be separated from S. balstoni by its penis morphology, which has eight spines on the head of the glans in an almost circular cluster. It roosts in tree hollows but has been reported to roost in buildings. It is known to share roosts with other similar-sized bats such as the Chocolate Wattled bat. A single young is born in November or December.(Churchill)
