See below Serphitidae is a family of microscopic parasitic wasps known from the Cretaceous period.

This family was described in 1937 by the American entomologist Charles Thomas Brues to classify a fossil insect caught in an amber piece from Canada.

After that, more genera were described and included in this family, like Archaeromma and Distylopus by the Japanese entomologist Hiroshi Yoshimoto in 1975, from fossils also found in Canadian amber, and Aposerphites, Microserphites and new species of Serphites in 1979 by the Russian entomologist Mikhail Vasilievich Kozlov and Alexandr Rasnitsyn, from Siberian amber.

[1] Serphitidae is placed with another extinct family, Archaeoserphitidae as members of the superfamily Serphitoidea, Serphitoidea in turn is the sister group of the superfamily Mymarommatoidea, the only living family of which is Mymarommatidae.

The clade containing both superfamilies is named Bipetiolarida, which is placed within the Proctotrupomorpha.
