Eastern mouse spider

Fact Box Species: Missulena bradleyi (QM) Family: Actinopodidae Body length: female: 20 mm male: 14 mm Habitat: In a well concealed burrow in open bush settings; the burrow is normally branched with two openings each closed by a door Toxicity: Male venom contains a nerve poison which is potentially as lethal to humans as that of the funnel-web spider, but mouse spiders are much less prone to inject it

Male, damaged Male blue spot

The most important characteristics of the female of this species are the glossy black colour, the shortened cephalothorax with its very widely spread eyes, and the very large chelicerae and fangs. The male is smaller and has a pale blue patch on the upper front surface of its abdomen. Mostly, females are dug up by accident, but if the weather is wet males sometimes wander into houses during their breeding season, which in the Toowoomba region is autumn and early winter.

Note that there is evidence that the funnel-web antivenom is able to reverse the effects of M. bradleyi venom on humans.

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