Megalyroidea

Megalyroidea is a small hymenopteran superfamily that includes a single family, Megalyridae, with eight genera (plus three extinct ones) and 49 described species. Modern megalyrids are found primarily in the southern hemisphere, though fossils have only been found in the northern hemisphere. The most abundant and species-rich megalyrid fauna is in Australia. Another peak of diversity appears to be in the relict forests of Madagascar, but most of these species are still undescribed.
