Checklist of British and Irish Hymenoptera - aculeates (Apoidea, Chrysidoidea and Vespoidea)Background: The checklist of British and Irish aculeate Hymenoptera (Apoidea, Chrysidoidea and Vespoidea) is revised. Species distribution is summarised for all species at the level of country (England, Scotland, Wales, Ireland and Isle of Man). New information: The 601 native species represent an increase of 25 on the 1978 checklist, comprising mostly new discoveries. This increase is nearly balanced by the 23 species now presumed to be extinct in Britain and Ireland.
Checklist of British and Irish Hymenoptera - IchneumonidaeBackground The checklist of British and Irish Ichneumonidae is revised, based in large part on the collections of the Natural History Museum, London and the National Museums of Scotland, Edinburgh. Distribution records are provided at the country level. New information Of the 2,447 species regarded as valid and certainly identified, 214 are here recorded for the first time from the British Isles. Neorhacodinae is considered to be a separate subfamily rather than a synonym of Tersilochinae. Echthrini is treated as a junior synonym of the tribe Cryptini, not Hemigastrini. Echthrus Gravenhorst and Helcostizus Förster are classified in Cryptini rather than, respectively, Hemigastrini and Phygadeuontini.
Checklist of British and Irish Hymenoptera - IntroductionThe last complete checklist of the British and Irish Hymenoptera was that of Fitton et al. (1978). Much has changed in the intervening 36 years, including many changes to the higher classification of Hymenoptera and, of course, the discovery of many additional species. In producing this checklist we (the authors of the various chapters) have tried to provide a useful entry to the literature dealing with the identification and classification of the species involved, particularly for the less familiar parasitoid groups. The checklist also begins the process of summarising data on species' distribution on a country-level basis. I hope that this will serve to stimulate increased interest in this relatively neglected part of the British and Irish fauna. This volume serves as a standard reference point for the British and Irish Hymenoptera fauna, and, hopefully, provides a backbone to recording efforts and the underlying taxonomy. Having an endpoint to this project has stimulated much research in to our fauna, including the critical examination of museum collections, and thus pushed some checklist sections to a state they might not otherwise have reached. Of course, a checklist is never finished. The next incarnation will be digital, and the checklist is already in the process of migrating to a Scratchpad (Hymenoptera of the British Isles), where updates will be maintained as and when changes occur.
