Coelioxys (Paracoelioxys) obtusispina Thomson, 1872

Coelioxys obtusispina Thomson, 1872 was considered incertae sedis in the previous European checklist (Ghisbain & Rosa et al. 2023). Based on genetic analyses of BOLD barcode data, C. obtusispina appears to be closely related to Coelioxys mandibularis Nylander, 1848, which belongs to the subgenus Paracoelioxys . The presence of lateral notches on the female S6 of C. obstusispina is a character shared with the other European Paracoelioxys species, which further supports the inclusion of C. obtusispina in this subgenus. We therefore place C. obtusispina in the subgenus Paracoelioxys .
