Ok, I had a very good look.
and I can see 3 humeral bristles in a triangle and small discal setae on the tergite 4, but not on 3, which would imply Periscepsia.
Periscepsia carbonaria is by far the most common species and can be found very late in autumn.
So, that would be my 95% guess.
Beware, it is a lot to ask to give an ID in such a difficult group, not matter how good the pictures !

theo.... I see a petiole.. in wing... :S
"Lastly, the common rhinophorids have a large petiole on the wing and an angled vein-M - as on this picture of Paykullia maculata. This species also has very distinctive shading along the wing veins, which makes it quite easy to identify."

but... the M vein is gently curved... so Tachinidae? or is this an exception?
ok. I understood about calypters that are bigger in tachinidae but not easy to say sometimes, because it is relative...
i cannot see those humeral bristles.. the wing seems to hide above hind tibia..
Thank you!
