Family Gasteruptiidae, genus Gasteruption. Species: ?

“gaster" = stomach; “upti" = bent backward (both Greek). Say (gas-ter-OOP-tee-ohn)

The Gasteruptiidae are one of the more distinctive families among wasps, with surprisingly little variation in appearance for a
group that contains around 500 species in two subfamilies (Gasteruptiinae and Hyptiogastrinae) and with 6 genera worldwide.

The propleura form an elongated "neck", the petiole attaches very high on the propodeum, and the hind tibiae are swollen
and club-like. The females commonly have a long ovipositor and lay eggs in the nests of solitary bees and wasps, where
their larvae prey upon the host's eggs, larvae and provisions.
