Key: Key to the West-Palaeractic species of Elaphropeza Macquart, 1827 (Diptera: Hybotidae).
This is the key as presented by Chvála (1971). At the time Elaphropeza was considered as a subgenus of the genus Drapetis and this has been the case until quite recently. The genus appears to be favouring warmer climates with larger numbers of species known from the Oriental, Neotropic and Ethiopian regions.
