Unknown Wasp
This is a female Oodera Westwood (Pteromalidae: Cleonyminae: Ooderini). Yet another accidental introduction into North America from the Old World related to woodboring beetles. It was first caught in New Jersey in 1969 so it has been here quite some time now. The only thing known about its life history in North America is that it has been reared from dead wood of Gleditsia (Fabaceae). Old World species are known as larval parasitoids of Buprestidae and Scolytinae. The enlarged femora and raptorial front femora are a dead give away for Oodera because it is the only North American chalcid with raptorial front legs. No one, as far as I know, knows what they use them for. Would be really interesting to know.

Enlarged Forelegs
Thanks! The body certainly looks like the Eupelmid wasps.
However, I wasn't able to find any photos in currently in the guide in which the Eupelmid also had such enlarged front leg femurs. hmmm
