Ismaridae
Ismaridae is a small, relictual family of parasitoid wasps in the order Hymenoptera. The family contains two extant genera: Ismarus, with approximately 50–59 described species worldwide, and the fossil genus Lubomirus from Eocene amber. All species with known biology are hyperparasitoids that parasitize Dryinidae, which are themselves parasitoids of leafhoppers, planthoppers, and treehoppers. Formerly classified as a subfamily of Diapriidae, Ismaridae was elevated to family status based on distinct morphological differences, particularly the absence of a facial projection for antennal insertion and variable fusion of metasomal terga.
Vanhornia
Vanhornia is a genus of small parasitoid wasps comprising four described species. It is the sole genus in the family Vanhorniidae, a group formerly placed in Proctotrupoidea but now classified in Diaprioidea. Species are known from North America, the Palearctic, East Asia, and Southeast Asia. All members are parasitoids of beetle larvae in the family Eucnemidae.
