It is a male G. dolycoridis or possibly clavatum.

Thank you very much, Theo.
I have other pictured but don't know which one could help make the decision between G. dolycoridis and G. clavatum.
I have the identification keys from Hans-Peter Tschorsnig and Benno Herting, but very difficult for me to understand everything !
Which detail do you need ???
measured on picture : 6,2mm

Have a good day !
