The Ephialtes (Hym. Ichn.) parasitising the Codling Moth

Extract
The Ephialtes which have been bred from the codling moth, Cydia pomonella, L., have usually been determined as Ephialtes (Calliephialtes) extensor, Taschenberg 1863. Two species have been confused under this name, and neither of them is E. extensor, which, from the description and from material examined in the Brauns and Thomson collections, is a synonym of Ephialtes punctulata, Ratzeburg (═Pimpla punctulata, Ratz. 1844) (syn. nov.). The type of the latter species has been examined, as have the types of Ephialtes caudata, Ratzeburg 1848, and E. crassiseta, Thomson 1877, which are the two species that were actually bred from the codling moth. These species may be readily distinguished by the relative lengths of the segments of the hind tarsi and also in the female by the form of the ovipositor. The following key distinguishes the three species mentioned above.
