With 3500 described species the family of Pteromalidae is one of the most species rich families of chalcid 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. One 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. My studies are based on the extensive material from the German Barcode of Life (GBOL) project and the Swedish Malaise Trap Project (SMTP). Information gained from barcoding aid in the identification of cryptic species complexes, which are then further differentiated by using other molecular, morphological, morphometrical, phenological and biological data.
