In my oppinion Trachys puncticollis rectilineata

Trachys fragariae or Trachys scrobiculata is also an option. Can you say more about the hostplant? Where do you find this species?

If possible, send also a photo of the underside, please.

Per quanto riguarda la pianta ospite, non hanno alcuna idea... usato la rete da abitudine, senza speranza per qualcosa... l'unico esemplare trovato.
Ho rifatto le foto, una con parte ventrale.

In my opinion is Trachys problematica Obenberger, 1918. I don't know if this is the actual name - the lot of names changing messed me

@ joro - T. puncticollis rectilineata must to have areolas on the whole pronotum surface, this one seems to have only close to the anterior and posterior margins of the pronotum.

Ok, the answer from Joro is correct. It is Trachys puncticollis rectilineata Abeille de Perrin, 1900.

Trachys problematica has longer hairs on elytra and the dots on pronotum are not so deep like in Trachys puncticollis rectilineata.

I also copied a picture of Trachys puncticollis rectilieata from Nicola Rahmé which you can see here:

now because of the dicussion of the others Trachys remembered about this.
Thank you Thomasius for you help
