Keys out to Cremastinae
using Wahl's subfamily key (1)
, and to Pristomerus
using Townes' key to cremastine genera (2)
. Note the ventral tooth on the hind femur and the sinuate tip of the ovipositor. Found on flowering goldenrod.
I don't have access to Dasch's volume on Cremastinae
so I can't take this one any further. TIA
