This is the family Torymidae (subfamily Toryminae). I can't tell you the genus, but it is NOT the most common genus (Torymus).

Hi Bob,

couldn't it be Monodontomerinae, even genus Monodontomerus?
Characteristics I'm referring to:
- mesepimeron not incised on posterior margin (upper part of last pic) for Monodontomerinae
- one tooth on hind femur (1st pic) for Monodontomerus sp

Looking forward to learning from you!

Marc,
I can't see a tooth on the hind femur in your image, so that's why I didn't go for Monodontomerus. If you can, check behind the head for the presence of occipital carina, and how high up or low down it is.

Hi Louis,

could you please check your specimen, if there's a tooth on the hind femur or if it's just an artifact, I've seen on the pic? Might help to clarify the taxa, as stated by Bob.

Best regards,

Marc

The relative length of ovipositor and hind tibia, approximate 1,7 à 1,8.

Good photography! Well, I now agree that it is likely the genus Monodontomerus. I have no idea if there are any good keys to that genus for Europe or not.
