Hello,
I photographed this
Medetera near the city of Lyon, middle-east of mainland France in September, 20, 2023.
Is this
Medetera flavipes ? Or could it be
Medetera media ?

I guess that many records of
flavipes belong to
media.
1. Fore coxa dark; tarsi dark from apex of basitarsus; clypeus
scarcely shining, with weak pruinosity; epistome matt;
ventral lobe of surstylus with two strong simple apical setae,
dorsal lobe of surstylus without dorsoapical seta; median
seta of epandrial lobes spatulate; 2.6–3.7 mm ..........
..........................................................................
М. flavipes
– Fore coxa yellow; segments 1–4 of all tarsi dark at extreme
apex; clypeus metallic shining, with weak pruinosity only
laterally; epistome greenish grey, with some bronze tinge
and with metallic spot venrally; ventral lobe of surstylus
with one simple and one club-shaped apical seta, dorsal
lobe of surstylus with strong dorsoapical seta; setae of
epandrial lobes flattened but not spatulate; 2.9–3.8 mm ..

М. media
Doli.

Thanks for the answer Igor!
However, some colleagues have noted your answer is in contradiction with the 2016 Negrobov & Naglis key of Palaearctic
Medetera and also with
that identification of yours.
Is the key you have used for my individual a new key?
