Taxonomic and nomenclatural notes on Geodiapria longiceps Kieffer, 1911 (Hymenoptera, Diapriidae) and synonymy of the genus Geodiapria Kieffer, 1910

This paper reviews the status of Geodiapria and its nominotypical and only included species G. longiceps . Geodiapria was previously understood to be very similar to, and doubtfully separated from the genus Basalys . We use integrative taxonomy (morphology, DNA-barcoding, phylogenetic tree building) to show that the valid name for what was G. longiceps Kieffer, 1911 is now Basalys rufocinctus (Kiefer, 1911) and that Geodiapria is consequently a junior synonym of Basalys syn. nov. The following taxa are new synonyms of B. rufocinctus : Loxotropa longiceps Wasmann, 1909, syn. nov. , G. longiceps Kieffer, 1911, syn. nov. , L. rufosignata Kieffer, 1911, syn. nov . Basalys rufocinctus is newly reported from Corsica, Germany, Norway and Spain.
