Notes.

German specimens were compared with the original description ( Nixon 1972) as well as the works of Papp (1978) and Tobias (1986), and they match perfectly the characters provided in Nixon’s original description, particularly: colour of legs, tegula, pterostigma, flagellomeres (more or less, the paler areas in flagellomeres are present but not as sharp as described by Nixon), ocelli in very low triangle, anteromesoscutum and scutellum sculpture, propodeum sculpture (lack of carinae, as described by Nixon), metatibial spurs, density and shape of spines on outer surface of metatibia, T1 and T2 shape and sculpture, length of ovipositor sheaths, partial widening of sheaths towards posterior end, and down-curved ovipositor. The hosts that in the past have been associated with this species are not from the type material and comprise two different Lepidoptera families: Tortricidae - Acleris holmiana (Linnaeus, 1758) ( Papp 1988), and Gracillariidae - Caloptilia rufipennella ( Hübner, 1796) ( Papp 1988) and Caloptilia fribergensis (Fritzsche, 1871) ( Marczak and Buszko 1993); therefore, we consider supposed hosts in need of verification. This species is illustrated in Fig. 22 .
