Curculionoidea, Dryophthoridae, some kind of a Palm Weevil. My closest hint I found would be Cercidocerus indicator or similar, maybe the same genus? But the markings are slightly different for really being Cercidocerus indicator, at least in my eyes...

Thanks shekainah, Mark, kel, Sigg and Rob. Mark, I'm not sure if it's in that family but it looks like I've spotted some others that probably are Brentidae.
