Parasite - Elasmus - Male
Perry County, Pennsylvania, USA

Size: ~ 1.5 mm
Associated with my captive fuscatus colony. Can we at least tell if this is Elasmus?

Moved from ID Request.

Thank you for the ID and helpful information!

I think this is a fair assumption. You can see the very enlarged, compressed, and disc-shaped hind coxae which are a distinguishing feature of this group. Other features include a slender, elongated body, long legs, triangular head shape, and swollen and flattened middle and hind femora. Males have four funicle antennal segments with the basal segment bearing three lateral branches as can be seen here. They can be parasitic or hyperparasitic on Hymenoptera, and they have been known to parasitize Polistes larvae. Nice find.
