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.
