General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills and elsewhere
A poisonous spider that can be lethal, but very, very rarely.
Poisoning usually occurs due to picking up material off the ground without gloves. They love corrugated iron.
They are generally black with a dark red diamond shaped stripe on their abdomen which extends from the top all the way round underneath.
The stripe goes bright red when threatened.
Diagnostically only the red hour glass underneath is relevant. As such, they can be missing the red stripe on top, are often brown not black, and also often have white stripes.
