Better fit is 'Stenolophus rugicollis' LeConte
Southwestern Stenolophus rugicollis LeConte is distiguished externally from very similar S. comma by pronotum with a distinctly rugulose (wrinkled) surface and usually with a sharp (longitudinal) rectangular dark macule in the middle; elytron with dark band shorter, usually limited to three intervals and with microsculpture crisper, less stretched, approaching irregular isodiametric lines. S. rugicollis is assigned CA, OR, WA by Bousquet (2012). I created a new species page for it on BugGuide.

Jim, Please change your database from S. comma to S. rugicollis which affect Moore numbers 116 and 185. Sorry for the trouble.
