Hi

This is perhaps asking too much given the shrivelled look of this specimen, but I thought the flattened palpi might give it away.
My own idea is that it is Fannia latipalpis based on t2 without av; cx3 with setae; t3 with short accessory setae below strong ad; palpi dilated and arista practically bare. Does this make sense?

The fly was taken on sugar bait on 18. x 2010 in a garden north of Copenhagen.

I've been doing some re-thinking.

The parafacials are bare except for a line of short setulae and t2 has an anterodorsal. This paves the way for Fannia atripes - a species with spoon-shaped palpi about a broad as the 3rd segment of the antenna.

Anyone feeling like commenting on this matter?

I use Rozkosny, Gregor & Pont and couplet 5 in the key to the females is where I frequently get it wrong!

Oops! Forgot the pic to prove my point B)

Parafacials with a row of short setulae.
It is either aequilineata or latipalpis.

Thank you, Nikita! Blagodarju!

I got it right from the start then.

I've made a last shot.
F. latipalpis has frons at level of upper eye angle broader than 1/3 of head width and arista virtually bare.
F. aequilineata has frons less than 1/3 of head width and arista distinctly pubescent.

With this in mind I think I'll go for Fannia latipalpis if you have no objections...

Walther, I have objections.
1. With all my deep and sincere respect to Rozkosny, Gregor & Pont, I'm not convinced that their key works OK in case of females aequilineata/latipalpis.
2. Beyond these doubts, arista is "distinctly pubescent", which is well visible on your images, so I'd choise aequilineata, if any.

Well, I'll settle for Fannia cf. aequilineata.

Thanks again :)
