FYI: Only two species of Scaphinotus are known in OK
of which only one "might" fit here: Scaphinotus (Nomaretus) cavicollis(LeConte). See LeConte's type specimen at https://mczbase.mcz.harvard.edu/guid/MCZ:Ent:602. The problem I see is that Alex's posted image does not show the required coarse punctures distributed over the entire the pronotum. Photographic trickery? If not, this might be another Nomaretus and thus, a new state record! Suggestions?

Looks like fissicollis to me
, but there’s at least one undescribed one in OK

Yes it does.
Someone should study this specimen. Guaranteed reward: either a new state record or an undescribed species.
