Thanks a lot! At least I have the genus...
?Could be S. cenisia or S. hispanica? (cited for my zone)

It looks to me like a typical southern female of Stratiomys lingicornis. It is surely not cenisia or hispanica because these species have big yellow spots on the abdomen...

Longicornis again??? :(:(
But this one http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=14418 was three times more smaller and had a different colour...

There is not much difference between 12 mm and 13-15 mm and the abdominal pattern is the same, and the color differences are partially due to the gender differences and a bit the camera... Still rather sure about the ID, the only other option would be singularior...

Yes, maybe this one was slightly bigger than I said first: better 15-18 mm... same size than S. potamida. Well, then I'll put as longicornis too. Thanks a lot Martin!!!
What are differences between singularior and longicornis?

From Rozkosny:
-Scape slender and long, about 5-6 times as long as pedicel; abdominal side-markings absent or very small, larger only in some South European specimens; male synsternum heart-shaped; female yellow frontal spots fused with facial patches (Figs. 52: 1-9) S. longicomis (Scopoli)
- Scape shorter, only about 4 times as long as pedicel; abdominal side-markings distinct, usually also enlarged at anterior comers of terga; male synsternum long and slender; female yellow frontal spots mostly isolated (Figs. 55: 1-1 1) . . . . . . . . . S. singulanor (Harris)

Thanks a lot for this key. Then I suppose than both specimens as S. longicornis are correct.
