It fooled me
I thought it looked like an Eucnemidae, but when it was on it's back while I was photographing it, it clicked and jumped a couple inches. I guess even false click beetles can jump.

yep
The term false click beetle was a misnomer, believing these beetles are incapable of snapping into the air. In fact, Many species of false click beetles can actually click. The common name is just a means to distinguish eucnemids from the true click beetles for different reasons, largly by the lack of a free labrum and straight anterior margin of the prosternum, just below the head.

Not a click beetle, but....
a member of the family Eucnemidae. It is Isarthrus calceatus (Say)
