Normally in
Geomyza hackmani the subscutellum is normally darker. The abdomen in
G. balachowskyi is normally more clearly banded.
I have seen a few specimens of
G. hackmani with vaguely banded abdomen and not so dark subscutellum. To be sure which species you are dealing with, you should study the shape of sternite 8 (which is often not readily visibile).
My best guess would be female
Geomyza cf. hackmani.
