Thank you Brian Dagley for confirming the id of this species for us

General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~9mm long.
S1 was the 1st Cerceris we photographed, in her nest in the ground. We thought this was a Masked Bee (Hylaeus sp).
We discovered the error when we caught & id'ed our 2nd specimen.
There is a ridge on the face between the antennae, which is also maked in a contrasting colour. This stands out and is unique to this genera of wasp, so can make the generic id of just the face in the nest.
