Identification.

Hacker (1968) revised the species. Since then, four new species have been described by Will (2007), one species ( Pterostichus rothi ) has been transferred from Anilloferonia to this subgenus (Will 2007), and one subspecies ( Pterostichus stapedius yosemitensis ) has been raised to species level by Bousquet (1999: 164).
