Thread subject: Diptera.info :: Which Chelosia female?

I collected this female Cheilosia on 25 May 2015 at Vindelsbæk Bro in the middle of Jutland, Denmark. It is a very good location along a broad creek.

When I use various keys, I end at uviformis. As that species is very rare in Denmark, so I am probably wrong.

Length: approx. 9 mm

Here are some data. I hope I use the right terminology.

Eyes with very few white hairs. You have to look carefully for them.
Lunula: dark orange.
Third antennal segment: yellow-orange, round and longer than wide.
Thoraic dorsum: Long yellow hairs.
Scutellum: one black bristle and several yellow ones.
Femur: black with yellow tip.
Tibia: yellow.
Tarsi: First segment of hind legs is mostly dark and all final segments are black; other segments are yellow.
Tibia: yellow.
Sternites: 1 with a very small shining part, 2 with larger shining part, but all sternites clearly dusted.

I attach two low-quality pictures. If you need further details or pictures, please let me know.

Hope you can help me identify this female.

Best regards
