I think Dasysyrphus intrudens
I think Dasysyrphus intrudens species complex, using the new Locke and Skevington key (Zootaxa 3660, 2013). I can't quite tell if the maculae on tergites 3-4 actually reach the edge of the abdomen, but they are shaped very much like the intrudens species complex maculae, particularly with the strong constriction in the middle. With such strong constriction, it could also be occidualis, but the maculae on occidualis are less strongly curved than on flies in the intrudens species complex.
