Hello Henrik, Spallanzania is a fantastic suggestion. I think that you may be correct. I've tried to key it and it matches with what is visible: two upright bristles beside the apex of the scutellum, reclinate ocellar bristles, pale basicosta and black tegula. Thank you for taking time to post, Henrik. I appreciate you :)

edite: only Spallanzania hebes is listed for Germany.
