Hi.

This is the fly which has been called "Minettia styriaca" on previous Finnish checklists. It does not look much like a Minettia, but I have a hard time placing it anywhere in Lauxaniidae. There are just three very old specimens in our collections, all unfortunately female.

Any ideas?

It has:
* two ventroapical spurs on mid tibia.
* black spinules on costa reaching middle of R2+3 and R4+5 but not more.
* no intra-alar in front of the prescutellar one.
* no distinguishing marks (spots, sutures etc.) on face
* one strong presutural dc just before the suture - but one specimen seems to lack this seta on one side (it is not just broken off but genuinely missing).
* no setulae on wing veins (dorsal or ventral)
* anterior wing margin weakly infuscated

If I ignore the presutural dc it keys out as Sapromyza carinatula Shatalkin, a species from the Russian Far East.
