Can anyone suggest a family for this wasp? Light trap, Townsville, Queensland.

I'm almost positive that this is a eupelmid, but the antennae don't match the typical eupelmid. Oh, well, just another example of how weird the Australian fauna can be, I guess. Can you check the marginal vein? A really long marginal vein would be consistent with eupelmid, while a really short one could indicate Encyrtidae (the bulging mesopleuron suggests it would be one of these 2 families).

The ventral row of pegs on the mesotarsus is not typical of (some) Eupelmidae?

This female reminds me of our european Anastatus spp (Eupelmidae), which have such an enlarged antenna, infuscated wings and a similar habitus. But I know nothing about the australian fauna.

The marginal vein looks to be of medium length. Does it help?

Thanks Bilule. I hadn't noticed the mesotarsus pegs.

Yes, the wing venation is much more eupelmidish than encyrtidish. Also the dorsal surface of the mesoscutum is typical eupelmid.
