Pterostichus praetermissus (Chaudoir, 1868)
is suggested by the diagnostic bead & groove seen along lateral portion of pronotal base. This is a sibling of P. commutablis and recently resurrected by Bousquet & Webster (2004). Brad, does specimen examination verify my image observation? If not, then back to P. commutablis.

Yes
There is a bead with a distinct groove in front of it on each side of base. Thanks Peter!
