Thank you Fauna_Mirifica for confirming the id of this species for us

General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~23mm long Male. In males the "Visible part of metasomal sternum VIII forming two separated lobes."
Another genus that looks quite similar to Sphex wasps is Prionyx. When we asked Fauna_Mirifica what the differences were, they said "Submarginal cell 2 is rhomboid in Sphecini, but it is rectangular in this specimen" a Prionyx. "The "hairy" patches on the metasomal side are also not found in Sphex, and the body posture is different (legs are usually more spread out in Prionyx)."
