The changing use of the ovipositor in host shifts by ichneumonid ectoparasitoids of spiders (Hymenoptera, Ichneumonidae, Pimplinae)
Accurate egg placement into or onto a living host is an essential ability for many parasitoids, and changes in associated phenotypes, such as ovipositor morphology and behaviour, correlate with significant host shifts. Here, we report that in the ichneumonid group of koinobiont spider-ectoparasitoids (“polysphinctines”), several putatively ancestral taxa (clade I...Takasuka, Keizo ; Fritzén, Niclas R ; Tanaka, Yoshihiro ; Matsumoto, Rikio ; Maeto, Kaoru …

On the spider parasitoids Polysphincta longa Kasparyan and P. boops Tschek (Hymenoptera, Ichneumonidae, Pimplinae), with the first host records of P. longa
The rarely recorded Polysphincta longa is probably widely overlooked in Europe as a result of confusion with the morphologically similar P. boops. Characters for the separation of these species are given, and host and distribution records, largely based on recent fieldwork, are presented. Araneus angulatus is shown to be the...Fritzén, Niclas R ; Shaw, Mark R
