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.
