Hi, this ~2 mm fly was sitting on chopped wood in NE Hungary, forest. No idea of the family.

Stenomicra springs to mind...

Would be great to have that genus  I expected Periscelididae or something alike. here's another phot:

No Stenomicra, as that has long rays on the arista. Periscelididae should have only one frontal setae, this one seems to have two. Perhaps still Anthomyizidae...

Can you confirm that the posterior crossvein is actually missing? Or is it very indistinct?

Hi, I made two images of the wing and maybe the reflections make it more clear. I don't see the crossvein.

Dear Paul, I suppose both photos of this (really Anthomyzid) fly on your web pages are of the same species. It is Stiphrosoma sabulosum (Haliday, 1837), female. Normally, the species lives in tufts of various grasses and the majority of specimens are brachypterous. The (less often occurring) macropterous form is markedly more frequent in female sex and I believe it is due better dispersal of the species (only macropt. f. can be found in Malaise trap or window trap samples). Very best wishes, yours Jindrich Paul - - - - Paul Beuk on https://diptera.info |

Thank You and thanks for Jindrich Rohácek also! I'll submit this to the gallery among with many other recent finds in some time (when I finally finish the work with my photos made in spring and preparate the collected specimens). |

Nice! I found this species several times in pitfall traps, but only brachypterous specimens.
