Pseudometagea
Pseudometagea is a genus of parasitic wasps in the family Eucharitidae, characterized by endoparasitic first-instar larvae (planidia) that develop internally within host ant larvae. The genus is notable for having evolved endoparasitism independently within Eucharitidae, exhibiting koinobiosis where the parasitoid allows the host to continue development. The life history has been documented primarily for P. schwarzii, which parasitizes Lasius neoniger. Adults are short-lived and typically remain near host nests.
