Thank you for your answer. The stripes on the mesonotum are in reality even more prominent than on the photo.

The article you cite is unfortunately not freely accessable. I now requested it from the authors. We will see, whether they will send it to me. But the description seems to fit very well. The species is rather new (2010) and seems to lack even in the Fauna Europaea, or is there a synonyme?

The location I found it is about 10 km from the Swiss border. If the species is new for Austria and perhaps someone who works in diptera research wants it, I could send it to him/her. I actually collect coleoptera and don't have a big diptera collection.
