Wasps of the family Proctotrupidae (Hymenoptera, Proctotrupoidea) are the small-medium (3-15 mm) size parasitic insects. The family combines 10 genera and about 50 species previously known in the Neotropic fauna. The hosts of Proctotrupidae wasps are the members of different families of Coleoptera: Anthribidae, Carabidae, Cleridae, Coccinellidae, Curculionidae, Elateridae, Erotylidae, Melandridae, Nitidulidae, Phalacridae, Staphylinidae. Most species are solitary endoparasitoids of Coleoptera larvae living in soil litter and rotten wood; some species parasitize larvae of Mycetophilidae, Sciaridae (Diptera) and Oecophoridae (Lepidoptera).
