That's a new family for me - great! Two species of Campichoeta are said to occur in our region - C. obscuripennis and C. punctum. The first one seems to have all-over darkened wings, but the latter shows the dark margins, as depicted in http://galerie-in...155118.htm. So I'll name my fly C. punctum as well.
Many thanks, dear Tony, to lead me to the right trace.
