Smooth, glossy carapace; head area is high, steep and broad with very large, bulbous jaws. Eyes are widespread across the front of their head. The spinnerets, at the back of the abdomen, are short and blunt. Females are uniformly dark brown to black and larger than males. Males have a bright red head and jaws and gunmetal blue to black abdomens. Body size up to 3.5 cm.


Red Headed Mouse Spiders live in burrows in the ground, often in banks of rivers, creeks and other waterways, and is sometimes found in suburban gardens. Males are usually found wandering for females during the day in late summer to early winter. They tend to be more common especially after rain. Females remain in their burrows. Females lay 60 or more eggs within an egg sac that she places into a brood chamber off the main shaft of her burrow. The spiderlings hatch over summer and remain with the mother into autumn when dispersal occurs. The spiderlings disperse by ballooning, a technique that is rare in mygalomorphs and possibly explains the relatively wide distribution of this species compared to other mygalomorph species. They mainly prey on insects and other spiders, but also occasionally on small vertebrates, such as frogs and lizards.
