Western broad-nosed bat
The inland broad-nosed bat (''Scotorepens balstoni''), also known as the western broad-nosed bat, is a species of vesper bat. It is endemic to Australia and is widespread throughout the inland, especially in arid and semi-arid regions. This insectivorous microbat, measuring 12cm in length, roosts in tree hollows during the day and forages over woodland and water at night.
== Description ==
The inland broad-nosed bat is a moderate-sized species of microbat. It features a characteristic broad square-shaped muzzle when viewed from above that is formed by swollen, glandular pads (Reardon & Flavel 1991, p.72). The fur colour of the species can vary from dark brown to a pale sand colour, with light grey-brown on the back and pale brown on the belly being most common (Churchill 2008, p.155). This species along with other broad-nosed bats have short slender ears, small eyes, a tail enclosed in the uropatagium membrane and only one upper incisor on each side (Parnaby 1999). Unique to male inland broad-nosed bats are the numerous spines on the glans penis, with up to 22 spines on the head in two long rows (Churchill 2008, p.155). Body measurements, especially forearm length, along with distribution are useful in identifying the species (Churchill 2008 p.110). The species can also be identified by its short tragus of 4 mm (Parnaby 2008, p. 553). Male inland broad-nosed bats tend to be slightly smaller than females (Reardon & Flavel 1991, p.72).

The species has characteristic echolocation frequencies of 34.1 - 38.7 kHz in WA and 28 -34 kHz in NSW.
