Goldenrod gall parasitoid fauna - male

Goldenrod gall parasitoid fauna - Male
Pennypack Restoration Trust, Montgomery County, Pennsylvania, USA
July 27, 2009
Size: 2 mm.

Moved from Eulophidae.

This belongs to the subfamily ...
... Tetrastichinae.

Moved from ID Request.
Thanks for this and all the others. I must clarify that all these galls came from the same field of goldenrods, but not from just one plant. So probably none of them come from the same females.
In addition to all these Eulophids, I found another Eulophid quite different in appearance, some Torymiids and a Braconid. Also the Cecidoymiid gall makers plus several different pupae. I would love to get the whole story, but I am sure that photos are not enough.

This appears to be another male, but came from a different female (why they look different). So it seems there were at least two separate parasitizing females that found their way into this gall complex. Characteristics of this subfamily including a subtriangular prepectus, wing venation, and dark coloration are apparent.
