Could this be Harpalus sp? - Laemostenus complanatus

Size: ~18mm
Could this beetle possibly be Harpalus sp? Or is it even possible to determine genus here? Found in moist soil under a potted plant.

Laemostenus complanatus, I think
a common, introduced species on the west coast
Moved from Pterostichitae.

does not look right
for Harpalus my guess is some pterostichine, but they are tough as nails to determine from an image....

welcome
look at the pronotal shape in all things Harpalus you can see that they are usually almost as wide, or close to the width, of the elytra, this one pinches in quite a bit....Carabids are such a pain if you dont work with them constantly, at least for me..

Ah true!
Ah yeah I had noticed that so I was leaning away from Harpalus the more I looked at photos

a guess not an answer - sorry
Agree w Guy that Pterostichines very difficult to ID. Requires angles of tarsi, etc. I'm chiming in here mostly so that I can be informed if/when someone much more advanced than I can figure it out for you.
My guess so far is Pterostichus herculaneus?
