Thank you Kate Sandiford for identifying this species for us

General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
Probably the largest wasp in Australia, with the body & head nearly 40mm long. Sorry for the poor quality photo's. I was still learning to use the new insect boxes (& I suspect I was nervous!). This one's body is covered in white hair, is black and has a brown/golden hue to it's wings. It's mandibles are something you don't want attacking you. At first I thought it was a hook. Then realised it was two crossed mandibles that were much bigger than any spider fangs I've seen! Why I captured it I'll never know. I can't remember doing it, I was obviously in shock
OR JUST STUPID. I originally identified this back in Feb as Prionyx globosus. But Kate used the key here to identify it for us.
While it looks like the antennae have 9, the end one bends so must be 10.
This is the 1st record for this species in South Australia on the ALA website (
