RES Handbook Vol 8 Part 2a. Hymenoptera 2. Chalcidoidea Section (a).

THE Chalcidoidea (Chalcid flies) form one of the largest superfamilies of the Hymenoptera, and are distributed in almost all parts of the world. Almost 2300 world genera and about 25,000 world species have been described. Although for Europe alone the totals are about 450 genera and 5000 species, our knowledge of nearly all of these remained very backward up to the present decade, for few entomologists were interested in them despite their great importance.
