Hi, I need help with ID here. Vienna, early Feb in a vinegar trap

An acalyptrate fly, possibly superfamily Sciomyzoidea.

Thanks guys! I am struggling with the term 'setulose' - does it mean 'hairy'? Because with R1 not setulose, prescutellar ac and strong postgenal bristles I reach Pseudoneuroctena senilis. But I am hesitant, as this would be a new species for Austria, apparently. So rather a Dryomyza (flaveola)?

The last wing image shows the tip of the subcosta, not of R1 so I dare not say with any certainty whether the tip of R1 is setulose or not (there should be a few in senilis). Setulosa means with small setae.

I intentionally took the frame of R1 together with subcosta, because there the small hairs on R1 could be seen best. I was not going for the tip of R1 because in the key it says 'Vein R1 setose along length'.
So now I know that these small hairs are not the feature to look at.

I won't have time to provide more photos until next week. Thanks for helping out so far!

R1 looks setulose to me, but the setulae are broken off. You can still see the pores of implantation (I think)
Is it from a malaise trap or so ?

Sorry, I just red vinegar trap. That might explain the poor condition

Yes Theo, in total I caught 10 individuals.
Maybe I find one with intact setulae, but I agree that on the 'whole wing' image there are pores visible where the setae broke off.
So a Dryomyza species.

Maybe pop one specimen in the mail? ;)

Here we have the prove: bristles on R1. So does it make it D. anilis?

D. anlis should have them along the whole length of R1. The picture only shows support for Pseudoneuroctena senilis, I think.

Thanks, Paul. I like that conclusion.
Do you want to get some specimens?

Hi Carnifex,

Could I get a few (male) specimens as well? Then I can compare them with my Mongolian material I collected last august...

Kind regards,

Ectemnius
