Dasygnathus trituberculatus, body length 23mm
Those beetles are active at night. They are dark brown to almost black in colour. Male and female are look different. They sometimes come to the light on summer night. We had identified this beetle as Semanopterus solidus. Thank you to our visitor Yannig Ponchel from Paris, he advised us by email that this should be Dasygnathus trituberculatus.
