From Iberian Peninsula in the West to Mongolia in the East, descending into Morocco , the Levant and Iran ( Fateryga et al. 2021 ). Notes. The available genetic data show a certain level of substructuring within Euodynerus curictensis , with three recognizable groups distinguished by geographic provenance ( Fig. 2 ): the first from Sardinia, the second from Morocco and the last ranging from the Italian Peninsula to the Caucasus and the Levant. The lone female specimen available from Sardinia, consistent with the Sardinian endemic subspecies E. curictensis sardous Borsato ( Figs 5C, H ), presents a genetic distance of 2.96% from the Moroccan specimens and 7.04–7.27% from the more widespread group, while the Moroccan and the widespread group differ by 3.77–4.04%, with the highest differences between Moroccan and Italian specimens. These genetic distances do not seem to correlate to constant morphological differences, and the highest intraspecific genetic distance (7.27%) is still well below the interspecific distances observed between E. curictensis and the other species of the nominotypical subgenus considered in this study, with the lowest being 19.68% between E. curictensis and E. dantici violaceipennis . For these reasons, the whole clade is here considered as a single taxon, E. curictensis , making E. curictensis sardous a junior synonym.
