Butler’s dunnart is a small marsupial, with a head and body length of around 88 mm and a tail length of around 90 mm. Its tail is thin and sparsely furred. The species is similar in general appearance to a range of small dasyurids occurring across Australia, including the Kakadu dunnart (S. bindi) and red-cheeked dunnart (S. virginiae) in northern Australia. All are generally grey-brown above and pale below, with large ears and eyes, and a sharply pointed muzzle. Butler’s dunnart probably feeds on a variety of invertebrates and small vertebrates.
