Epirhyssa Cresson 1865 is a large tropical genus of the family Ichneumonidae. It is the most diverse genus of the subfamily Rhyssinae with about 118 species worldwide. In this study we conducted four long-term field inventories to review the Peruvian Amazonian species of the genus. We provide illustrations, diagnosis and an identification key to the species currently known to occur in the regio...

Adelognathus leucotrochi Shaw & Wahl sp. nov. is described from Britain where it is a univoltine slightly gregarious koinobiont ectoparasitoid of late stage larvae of the tenthredinid sawfly Nematus leucotrochus Hartig feeding on Ribes uva-crispa. Defensive reactions by the host to prospecting females are described. The developmental biology of A. leucotrochi is described in detail: the host is...

A new species, Polysphincta punctigaster Varga & Reshchikov sp. n., the second known species of the genus from the Oriental region, is described from Thailand. Polysphincta asiatica Kusigemati, 1984 is considered to be a junior synonym of P. boops Tschek, 1869 (syn. nov.). Polysphincta longa Kasparyan, 1976 is recorded from the Oriental region for the first time.

Flacopimpla barathrica sp. n. and Zatypota flamma sp. n., belonging to the Polysphincta genus-group, are described, the former from Fennoscandia and the latter from Hungary. Like other species of this group for which the natural history is known, the new species are koinobiont ectoparasitoids of spiders. They have been reared from the theridiid spiders Thymoites bellissimus (L. Koch) and Parast...

This paper is aimed to summarize the information available on the parasitoid complex of the European Grapevine Moth (EGVM), Lobesia botrana (Denis & Schiffermüller, 1775) (Lepidoptera Tortricidae) in Italy. The list is the result of the consultation of a vast bibliography published in Italy for almost two hundred years, from 1828 to date. This allowed the clarification and correction of misunde...
