Hi Jürgen, I'm quite sure, that your last photo shows a male
C. vicina: Tergit 3 has a shifting pattern and basicosta doesn't seem to be black (
vicina: "basicosta pale, can be infuscated, brown but not entirely black", O. Sivell). To be "dead sure" you should try to make clear lateral shots, showing anterior spiracle, gena etc.
