Coelioxys (Coelioxys) lanceolatus Nylander, 1852

Coelioxys lanceolatus Nylander, 1852 was considered incertae sedis in the previous European checklist (Ghisbain et al. 2023). Based on genetic analyses of BOLD barcode data, C. lanceolatus appears to be closely related to Coelioxys conicus (Linnaeus, 1758), which belongs to the nominate subgenus. We therefore place C. lanceolatus in the subgenus Coelioxys sensu stricto .
