Phloeodes diabolicus (LeConte)
Phloeodes plicatus (LeConte)
I've had the pleasure of collecting both of the currently described species of Phloeodes from Mexico northward. P. diabolicus, I have found several times in the Central Valley. P. pilcatus, my friend spotted for me along a sea side trail when vacationing to southern California. Both of which only occure in Oregon(?) southward in the west desert regions. There are quite a few of these beetles that stand out; most notably in tropical countries.
