Thank you Milo van Loon for confirming the id of this species for us

General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~10mm long females.
We thought this was a Masked Bee (Hylaeus sp).
We discovered the error when we caught & id'ed our 2nd specimen.
We beleive they are different species as the base of the antennae is a different colour.
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 id of just the face in the nest.
We caught one with the same face markings, hence the known size.
Photographed 2 females in Mar & Oct.
