Wingless Aculeate - Methocha - female

Wingless Aculeate - Methocha - Female
Galena Gateway Park, Jo Daviess County, Illinois, USA
June 1, 2016
Size: ~8mm
Collected in a restored prairie near forest with a flight intercept trap at ground level.

I'm having a hard time getting an ID on this one. It seemed dryinid-like, but there are ten flagellomeres (12 antennomeres total) and the foretarsus is not chelate. It seems to key to Bethylidae, but it doesn't match with anything I'm familiar with for that family. Any ideas?

Dryinid (female)…
The ten antennal segments, six visible abdominal segments, dilated fore femurs, and the abdomen with a marked basal constriction are suggestive for a dryinid. The front tarsus in females is usually chelate in females, but not always. Bethylids always with 11-13 antennal segments.

10 flagellomeres
There are 12 antennomeres (10 of which are flagellomeres).

The only Nearctic dryinids without chela are the two genera of Aphelopinae, both of which are in the guide and look nothing like this specimen.
