Nice. Did you consider dolini, which is more common in central Europe ?

Thanks a lot, Theo!
Yes, I did and this is from Whitmore & Perry: "M. dolini has light-coloured setulae on the occiput and the posterior part of the postgena, whereas these are exclusively black in M. striginervis"
plus "in M. dolini the wing is usually hyaline in males but often conspicuously infuscated in females, antero-distally between veins R1 and R4+5 and along crossvein dm-cu and the distal part of vein M (Fig. 3F); in M. striginervis the wing is usually entirely hyaline in both sexes, sometimes slightly infuscated around the veins in females"
plus "shape of abdomen in dorsal view – in M. dolini the 3rd and 4th abdominal tergites are broader than syntergite 1+2, giving the abdomen a lozenge-shaped appearance, particularly in females; in M. striginervis syntergite 1+2 is broader than tergites 3 and 4 and the abdomen is gradually tapering to the tip"
Sorry - lot of text and some "usually"

Greetings, Eric Kloeckner
