Ci-joint la réponse de Matthias Riedel :
Est-ce-que ça ne serait pas plus prudent de la reclasser tout simplement en Exetastes sp. F ?I avoid to determine Ichneumonids by fotos since there a so many similar looking species (more than 3500 species in Germany). Your fotos show a female of Exetastes but I am not able to determine it to species level, E. gracilicornis is possible.
