Based on the antennae and size, I would say Cigarette Beetle (Lasioderma serricorne), and that is considered a high-risk pest. They target books bindings, so I would examine those very closely for any fine powder from adults feeding and then go from there (checking for larvae). Any books that might be damaged should be able to be put in a freezer to kill the bugs. Definitely a concern!

Finally I managed to take some more photos, I attach a couple of them that might be useful for better identification through the antenna. It is the same shot but with different focus, I think they are two insects of the same kind.

We are in Italy, Florence. Unfortunately, the antennae of the captured exemlars are not visible because of their location and the glue of the trap. Next week I will be able to check for more captures and hope that the antennae will be visible.

Tricorynus herbarius (Gorham) belongs also to Coleoptera (Anobiidae) @Anna In which country / region of the world do you live and found the beetles. That could help for the ID of the beetles.

There is a beetle called the Mexican book borer, Tricorynus herbarius that looks very similar to the drug store beetle. So does the hairy fungus beetle. A view of the antennae could help.

I found three of them in a crawling insect trap (!), with lure. Another was caught in a appropriate trap for flying insects. No food in our storage, nor herbaria. Many wooden objects and some books, that are probably the reason of the presence of such a type of pest...
