Ismarus (wasp)

Ismarus is a genus of wasps belonging to the family Ismaridae, and presently the sole extant genus in the family (a second genus was recently removed[1]). About 50 species are known in this small relictual group, all of which appear to be hyperparasitoids that parasitize Dryinidae (that attack leafhoppers).
