I looked through Peter's book and PaDil and couldn't see a match. Unflortunately I only got this one shot and despite searching I couldn't find it again. The closest I saw on PaDIL was Leioproctus nomadiformis but as that was from FNQ, highly unlikely. Lasioglossum (Australictus) peraustrale was another option.
@PeterA. I would appreciate your thoughts.
