That it matches with (latest, not old, that didn't mention wing tip's darkening) dives ' descriptions is smooth and clear. Matter is that officially dives is only in the checklist of non-insular Italy, and for sure not in Germany or Netherlands or Denmark. Why there's a similar gap? I think that this "wing's apex darkened" Xanthogramma stackelbergi/pedissequum like is widespread, but there's no consensus yet about its detachment from the other two. Anyways, considering its particular traits (hind leg, wing's apex etc.), it appears to have dignity as independent species.
