This looks like a species with fairly broad wings, indeed it is reminiscent of C lacunana, although I don't think it is that species. There are several closely related European species in the genus Phiaris, although several of these tend to be limited to more northern latitudes. One possibility is Phiaris obsoletana, although pictures (perhaps of fresh individuals) show a somewhat brighter looking moth. Whatever else it is, I don't think it a Gypsonoma which tends to be more of a black and white species with a contrasting tan spot in the corner of the wing.
This does look very much like pictures of Phiaris obsoletana and this species appears to have been reported from Italy.
