I don't know much about European Simuliidae. It belongs to the half of the genus
Simulium that includes
S. variegatum (legs with pale markings, vein R without hairs basally). If there are hairs on the anepisternal membrane (behind the sclerite, not on it) then it belongs to a different species group.
