Chalcid - Female

Pteromalidae…
As Richard mentioned, the wing venation does match well with this family. A key feature separating these two groups is the antennae which are extended in this group, and not in most Eulophids. Also in Eulophids, the axilla extends past the tegula, which is not the case here.

See reference here.

Both look very similar indeed...
And are most likely to be at least congeneric (i.e. of the same genus). The problem is, wing venation doesn't match with family Eulophidae, but with family Pteromalidae. Despite the excellent resolution of your pictures, I'm not able to count the tarsal segments nor to check the presence of annelli at the basis of antennal flagellum.
Therefore, unless a Chalcid expert examines these pictures, it's more safe to stay at the - somewhat frustrating - superfamily level,

This definitely has more than 4 flagellar segments
Making it a Pteromalidae.

Thanks Richard
I will post some more images of this wasp to see whether we can narrow it down any further.

There are many similar images
on the base wasp page here. Can any of those be ID'd?
