This species is found much less often than other mouse spider species but is presumed to have similar behavioural patterns. The female of this species is a glossy black colour with a shortened cephalothorax, very wide spread eyes, and large chelicerae and fangs. The male is more often noticed although it is entirely black and relatively small for a ground-dwelling mygalomorph spider. Mouse spiders dig deep burrows with a door and excellent camouflage that they are rarely discovered except when the males appear after rain in Autumn or a female is accidentally excavated.

Spider(s) with a very similar appearance: Missulena occatoria and Missulena bradleyi.
