Thank you Martin Lagerwey & Nick Monaghan for confirming the id of this species for us
General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
We suspect this is Ditropidus pulchellus. Most images of D. pulchellus have a red pronotum though.
This one also seems to have a slightly different scutellum.
We were wondering if these differences were gender based. Nick suggested it could be a regional variation. Martin agreed and said "I would expect regional or genetic variation. Gender dimorphism is minimal in this species although pronotum colors do vary by gender in Cryptocephalinae including a few Ditropidus and a few Aporocera." Martin also said "There is nothing else close in the Victorian Museum collection."
The only way to be sure this is D. pulchellus or not would be to dissect it.
