Perhaps G. rotundatum? Please help to get the ID.

Hi kuv, I think G. rotundatum is close but this male here has the "scutellum with a continuous central line of dusting, which continues usually on the posterior 1/5 - 1/3 of the thorax".
So it's probably G. dolycoridis (G. desertorum is an east-palaearctic species). (T&H key + translation by Rayner, Raper 2001)

The other important characters like hairs on thorax and abdomen and acr and dc bristles are not visible...

Thank you very much Eric :).
So I'll change headline with a questionmark.
