Hello, I found some specimens of this species swarming a few days ago in Romania, near the Black Sea shore. They are D. femoratus?

No, there are.
clearly three rows of spines on front tibia, so it is febrilis or similar. You would need to study the genitalia.

Hi Theo, thanks for your message, I was thinking it's D. femoratus because of the orange front legs (they seems to be black in the other species).
Is there any available key for Dilophus/Bibionidae for Europe?

I was looking in that paper, but I see that the Dilophus febrilis group is characterized by 2 rows of spines on the front tibia, not 3 like in my specimen. So I am a bit puzzled with this one ... I hope the next pictures will help to ID it.

Well, I did count the apical ones and J-P does not, so his 2 and my 3 are the same. Genitalia look OK for febrilis as well, definiely NOT femoratus.

The 3 specimens that I have (including this one) were ID-ed as Dilophus clavicornus Skartveit & Kaplan, 1996, by Jean-Paul Haenni, afters examining the specimens.
New specie for Romania :)
