Hello,

First I thought she was a Rhagio lineola but Rhagio have an open anal cell, and here the anal cell is closed.

Then I thought she was an Atrichops crassipes but finally I don't think because this species has an entirely yellow front femur, the wing is a little darkened under the stigma and the third antennal article is larger.

May be a Chrysopilus ? But I didn't find any similar.

Hello Jessica,
In Rhagionidae aberrations in wing venation occur more often than in other Diptera families, certainly in material I've seen. A Rhagio lineola with a closed anal cell is something I've seen before from the Netherlands. So I'd say your original identification is correct!
Kind regards,

I second that. Excellent observation by Jessica, most keys are simply incorrect.
