Proctotrupes are small, typically 2–5 mm in length, with a compact body form. They possess a characteristic petiole (narrow waist) typical of Hymenoptera, reduced wing venation with few closed , and with 13 segments in females and 14 in males. The forewing has a distinct pterostigma. Separation from other proctotrupid requires examination of hindwing venation, mesoscutal structure, and metasomal tergite sculpturing.
