Description
The carapace is a glossy brownish-black in colour, the back and sides of the abdomen a dark maroon-brown with a paler underside. There are four pairs of pale markings on the upper and lateral surfaces. The venom contains excitatory neurotoxins.[3]
Distribution and habitat
The species occurs in the southern Eyre Peninsula region of South Australia. The type locality is 6.5 km south of Coulta.[2] The spiders are found in open forest and woodland habitats.[3]
Behaviour
The spiders construct burrows, without surface triplines, in or beneath leaf litter. The burrows contain a side chamber and have an entrance with a soil door in a collapsible silk collar.[3]
