Darkling ID

[Elliot]

Hi, I have a bunch of darklings and was wondering if anyone could help me ID a few? It seems many darklings look identical but are different species. I believe they are all Eleodes and the large one is eleodes armata? Thanks for any info!

That would be Coelocnemis dilaticollis, (formerly C.californica), there are no Coelocnemis in any of those pics. 

They are all Eleodes, the larger individuals with femoral spines on all pairs of legs are E.armata. Not sure what species the smaller ones are, but definitely some sort of Eleodes, Coelocnemis have golden hairs on their tibiae.
