The keys below are from Townes and Townes' 1960 revision, which treats this group as the subfamily Ephialtinae. Their Ephialtinae is broader than Pimplinae as this site circumscribes it — it also takes in Poemeniinae and Rhyssinae — so the tribal key crosses subfamily lines. Several genus names have changed hands since 1960; terminals are given under their current names, with the 1960 name noted. Species keys are on the respective genus pages.
