Difficult. I attach 2 more pictures.
Unfortunately the tip of the hind tibiae is not visible in any picture. The arista seems to be a little lighter than the pedicellus and basoflagellomer and at least the left wing stigma looks light or yellow-brown. Now I think the probability is higher that it is an Chalcosyrphus valgus. If you agree I will store it as Chalcosyrphus cf. valgus.
