Interpretive Summary: Parasitoid wasps are potent natural enemies of many species of pest insect and are critical elements in biological control research. Identification of parasitoid wasp species is a key to the success of biological control. This paper describes two new fossil species, one belonging to a genus that is still living today, providing critical insight into the evolution and morphology of these wasps, many of which are biological control agents of stink bug and their relatives. Research entomologists, biological control workers, extension agents, and APHIS cooperators worldwide will find this research product essential for their own work.

Technical Abstract: The generic concepts of Archaeoteleia Masner and Proteroscelio Brues are expanded to accommodate two new species that are here described: Archaeoteleia astropulvis Talamas sp. n. and Proteroscelio nexus Talamas sp. n. A specimen of Archaeoteleia from Baltic amber is illustrated and discussed. Diagnoses of Proteroscelio, Proterosceliopsis Ortega- Blanco, McKellar & Engel and Bruescelio Ortega-Blanco, McKellar & Engel, a key to Cretaceous platygastroid genera with 14-merous antennae, and a key to the species of Proteroscelio are presented.
