Beetle ID

I know it's a specie of darkling beetle, but I don't know it's specific scientific name. This one is the biggest darkling beetle I have ever seen. It's back also has this weird patter. I caught it last week in Sonoma ca in a woodpile next to a creek. Any ideas?

 

[Lucanus]

Might be Coelocnemis sp.
