Lauxaniidae_Sapromyza sp.(female) is correct? Region Malá Fatra Terchová about 600 m above sea level. Thank you very much for your help. I made a photo of 21.07.2011.

I think this is most likely
sexpunctata too, but cannot 100% eliminate
opaca, the shiny dorsum could be from the blight flash?
Be cautions of just counting spots, with
Sapromyza. quadripunctata/quadricincta often have 4 visible spots and
sexpunctata/opaca usually have six, but there are exceptions, and spots can be concealed under overlapping tergites, especialy on dried specimens. One needs to look at the ocellar bristles to separate the two groups.
