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.
