Jan is right, a female of the genus
Geomyza [Opomyzidae].
Geomyza balachowskyi or
G. hackmani. The abdomen seems to be banded what points to
G. balachowskyi. However, the post scutellum seems to be rather dark what point to
G. hackmani. Unfortunately the colour differences are not totally reliable for identification. To be sure you would have to study sternite 8 (normally retracted).
