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

Hi Graeme,

due to the facts, that
- the stigma seems to be clearly separated from marginal vein, it's obviously not a Sycophila sp. (Eurytomidae) and
- there are more then four funicular segments, which excludes Eulophidae
it might be a Megastigmus sp. male (Torymidae).

I'm curious, what the experts will say!

Best regards,

Marc

When you blow up the image of the wing the stigma is definitely connected to the marginal vein. Does this change your opinion.

It is definitely the subfamily Megastigminae in the Torymidae, of which Megastigmus is the most common genus. I am not familiar with the other Australian genera of this subfamily, but I see nothing to suggest that it is not Megastigmus.
