Thank you Villu Soon for identifying this species for us

General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills and elsewhere
These are under 10mm. Other visually similar genera are Chrysis, similar size, & Stilbum, which is closer to 20mm. Villu said "Primeuchroeus has no teeth at the end of metasoma (Chrysis usually has 4 or 6 teeth but other character states are also possible). Primeuchroeus has characteristically curved lower edge of mesopleura. Frontal carina is also typical for Primeuchrous. Radial vein of forewing is usually widely opened in Primeuchroeus but it is not well visible in these photos."
