HEITLAND, W. & H. PSCHORN-WALCHER (1992): A brief note on unusually high superparasitism in some sawfly parasitoids (Hym., Ichneumonidae: Euryproctini). - Mittl. Schweiz. Entomol. Gesell., 65, 75-79.
Several cases of unusually high superparasitism in some endoparasitoids of sawfly larvae are described and discussed. All observations refer to members of the tribe Euryproctini of the ichneumonid subfamily Ctenopelmatinae which are also characterized by the possession of a protracted trophamnion stage. The peculiar, heavily armoured first instar larva of Phobetes atomator (MULLER), a parasitoid of Selandrai sixii VOLLENHOVEN, is also described.
