This Cordilura has a bare arista which narrows to hyalipennis/ustulata, though the wing tips does not show an obvious shading. The morphological key points by Stuart G. Ball (2014) is pteropleuron hairing and setulae presences at the apical portion of R1. I find pteropleuron to be hairy, and no obvious setulae above R1. Both pointers towards hyalipennis. Also, M1+2 is sinuate, but not strongly as it should be for ustulata.

The specimen was not collected, and I have just a single but decent shot of it. It was found 4th June 2013 40 masl 63 degrees N, in an overgrown old farmland on an offshore island. According to Fauna Europaea hyalipennis is yet found in Britain and Sweden only.

Any help is appreciated as always!

Cheers Jørn

Thanks Piet,
I was a bit puzzled about the large inner frontal 2-3 tarsal segments, and if not Scathophagidae it must be Anthomyiidae. To be continued...

After some checking I think Alliopsis is a good lead, and came over this thread, pointing to the sylvestris group baced on the tarsal pattern: https://diptera.i...d_id=60469

Not sure at all, but thread name changed to attract attention.
