Abstract
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 Basalysrufocinctus (Kiefer, 1911) and that Geodiapria is consequently a junior synonym of Basalyssyn. nov. The following taxa are new synonyms of B.rufocinctus: Loxotropalongiceps Wasmann, 1909, syn. nov., G.longiceps Kieffer, 1911, syn. nov., L.rufosignata Kieffer, 1911, syn. nov. Basalysrufocinctus is newly reported from Corsica, Germany, Norway and Spain.
