Taxonomic Note.

According to Bousquet (1999: 145), this group is closely related and possibly paraphyletic in regard to Myosodus Fischer von Waldheim, a subgenus of 22 species centered in the Caucasus Mountains. Brinev and Shilenkov (2001) retained Tundraphilus as a valid subgenus, listing Pterostichus sublaevis Sahlberg, Pterostichus orion Tschitschérine, Pterostichus pfitzenmayeri Poppius, and Pterostichus kamtschaticus Motschulsky in it.
