Exploring the biodiversity of North and Central European Pteromalidae (Hymenoptera: Chalcidoidea) by integrative taxonomy

Parasitoid wasps (Hymenoptera) play a key role in nearly all terrestrial ecosystems by controlling the populations of their arthropod hosts. With 3500 described species the family of Pteromalidae (superfamily Chalcidoidea) is one of the most species rich families of parasitoid wasps. About 800 species have been recorded from Central Europe, representing nearly half of all Chalcidoidea known from that area. Correct species level identifications are however complicated by the existence of cryptic and dimorphic species. Hence, an integrative taxonomic approach, combining different methods for species level identification, can help to solve this problem.

One of these methods is DNA barcoding which employs molecular data to identify species. The first goal of my work is to complete the existing DNA database for the family of Pteromalidae in Central Europe and to test the suitability of the mitochondrial barcoding gene (COI) for correct species level identification within this family. The second part of my work will be a comprehensive taxonomic revision of a monophyletic and species rich subgroup of Pteromalidae. This revision will be mainly based on recently collected material from the German Barcode of Life (GBOL) project and the Swedish Malaise Trap Project (SMTP). Species will be diagnosed and described by integrating molecular, morphological, morphometrical, phenological and biological data.
