Lats night there was a nuptial flight, during this i caught a bunch of queens all from the same species. There does seem to be individual variance between them, pertaining to gaster length and height as well as thorax height. These differences are pretty minimal.
I would guess Iridomyrmex (it's my default after the Argentine ant) except for the head, which is unusually long and strongly V shaped (at the connection to the thorax).
