Xylobiops in Texas
There are three species of Xylobiops found in Texas. An additional species is found in Mexico and possibly southern California and Arizona. A preliminary document that is mostly an excerpt for now has been uploaded to my website to help with identifying these species.
The most obvious character is pilosity. If the beetle is glabrous, it's X. basilaris. If the beetle is hairy, it could be X. texanus or X. sextuberculatos. I've uploaded a document that includes a key to the genera of Xyloperthini and a key to the species of Xylobiops.
