Moved from Polopinus.

Darkling Beetle
belonging to the genus Polopinus Casey, 1924.
It seems to me Polopinus hubbelli Kritsky, 1989, but take a look to other species too: http://entnemdept.ufl.edu/teneb/Tenebrioniformes.htm

 
Polopinus
Thanks a lot. I found it in an oak log, not in pine though. Perhaps it is Polopinus ingens Casey 1924?
Anyway, there aren't any Polopinus in the guide yet, and I've got several other pitcures. How do I move it, please?

Would this also be a darkling beetle? Perhaps a Polypleurus species?

 
Keys?
The four species are very similar among them and I haven't got keys.
It seems to me that the front angles of the protorax are more convergent anteriorly in hubbelli and youngii, while they're rounded in nitidus and ingens.
But, the elytral puncturing is posteriorly obsolete in youngii.
So I've selected hubbelli.
Nonetheless, I don't know whether I've selected correct characters.

Other pictures would be desirable.
