Hi,
My new difficulty. I am sure subscutellum is big
I thought with this "muscid" aspect it would be easy to find a genus, but not really.
My better guess would be
Medina, but I can't find it really convincing.
I'd be happy to have another opinion.
Specimen come from a wet pasture, central France.
Apical scutellum hairs are broken (but exist)
post notal bristle bigger than first post alar.
Hairs bare
4 Kts (but one is small, about half the others)
Prostenum hairy
1ad on medial tibia.
Cheeks bare

It is, indeed, clearly a Blondeliini.
Gut feeling is male Meigenia.
Check the propleuron for small hairs.
Erect apical scutellars (I know, borken off, but pores can tell often a lot about orientation) would support this as well

Of course,
Meigenia!!!!!!
Can't say why I rulled this out.
Propleuron is indeed hairy (not easy to see thought). Basing on the apical pores insertions of the scutellar bristles, they must have been angled from 45 to 60°
Following the rest of the key, this is apparently
M dorsalis (front not wide, bares eyes, cerci andsurstyli straight and long haired)
Thanks for your help!
