Evanioidea is a small Hymenopteran superfamily that includes three families, two of which (Aulacidae and Gasteruptiidae) are much more closely related to one another than they are to the remaining family, Evaniidae. There is a rich fossil record, however, that helps fill in the gaps between these lineages. They all share the trait of having the metasoma attached very high above the hind coxae on the propodeum.
It is a poorly-known group as a whole, with some 1100 known species in total, and a great many species are still undescribed. While each of the three families differs in biology, within each family they are remarkably uniform in appearance and habits.
