The adults are nectarivorous and the larvae are parasitic in Hymenoptera, Orthoptera, Blattaria and Diptera. Eight hundred species in 56 genera are known, with worldwide distribution. A list of 15 species in four genera recorded from Mato Grosso do Sul State, based on the available bibliography and the identified material from several Brazilian collections, is provided. The collections are concentrated in Maracaju municipality, in Cerrado biome, with only one exception. It is necessary to increase the sampling in other regions and environments of the state, to fill the sampling gaps.
