D. veluchense, not for sure: it should show no (or a very fine and split) sutural stripe. Cf. here D. arcadicum is a synonym of D. eugeniae eugeniae Ganglbauer, 1885, but this species comes from Peloponnese.
Is the scape covered with raised hairs? Which is its body size?
Oui en effet krueperi Gnglb est plus probable ! La ligne blanche suturale sur veluchense Brg diverge nettement au niveau du scutellum me semble t'il ! Pas chez krueperi comme sur la photo.
