Anasimyia lineata seems more probable indeed. It has a prominent snout (which seems to make the triangular shadow) and orange antennae.
Helophilus groenlandicus is absent from Germany according to Fauna Europaea. Its face looks very different and has a shining black stripe; the antennae are dark.
Views from different angles would be helpful!
