Unexpected diversity in Central European Vespoidea (Hymenoptera, Mutillidae, Myrmosidae, Sapygidae, Scoliidae, Tiphiidae, Thynnidae, Vespidae), with description of two species of Smicromyrme Thomson, 1870.

The present study presents DNA barcoding results for 134 species of Central European Vespoidea, families Mutillidae, Myrmosidae, Sapygidae, Scoliidae, Tiphiidae, Thynnidae, and Vespidae, including DNA barcodes for 100 of the 114 German species. DNA barcoding resulted in unexpected diversity in several families, each with two or more genetic clusters identified by Barcode Index Numbers (BINs). Smicromyrmeburgeri Schmid-Egger, sp. nov. and S.langobardensis Schmid-Egger, sp. nov. are described as new from Germany and Italy, respectively. A neotype is designated for Smicromyrmerufipes (Fabricius, 1878). The results of DNA barcoding are discussed in respect to detecting cryptic species and refining species limits.
