Just received confirmation from Jindrich Rohacek that it is indeed either
Anthomyza collini or
A. anderssoni. There is a high probablility (95%) that this is
A. collini.
A. anderssoni usually has a more reddish thorax and should be found in
Typha growth. But to be totally sure, examination of the terminalia is required.
