Some kind of Cymatodera, I think. (C.undulata, C.wolcotti or other?)

Somewhat attracted to light, I suppose.
Found during night time hiding in a shadow place but close of a lighted area (an outdoor lamp mounted on the wall).
Full of dust. I tried to clean it with a small brush painter (second photo), some insects accept that, more or less.
Captured for photo, this one was very active, continuum moving. For shooting, was need to put in the refrigerator for a while. But it come back pretty fast. So this one was difficult to shoot, even if it is not a small one.
