Pterostichus (Lenapterus) subrugosus: Morita (1995) : 4; Bousquet (2003): 497.

Other consubgeneric species examined. The following species were investigated through literature: P. cancellatus (Motschulsky) by Sundukov (2005); P. vermiculosus (Ménétriés) by Sasakawa & Kubota (2005).

Notes. Pterostichus marginatus was described from southern Sakhalin but has been forgotten since its description and treated as incertae sedis in the Palaearctic Catalogue ( Bousquet 2003, 2017). Our comparison of the syntypes of P. marginatus with a photo of a female paratype of P. wellschmiedi ( Kirschenhofer 1985, fig. 9) and with specimens treated as P. wellschmiedi revealed that P. wellschmiedi is a synonym of P. marginatus . Moreover, comparison of this Sakhalin species with P. subrugosus from Hokkaidô revealed the relationship between the two taxa. Although the previously reported differences in external characters between the two (e.g., flatter elytra with less frequently interrupted intervals, and the absence of metallic luster of dorsal surface in P. subrugosus ; Sundukov 2005) were confirmed, no conspicuous differences were found in the structure of the endophallus. Thus, P. subrugosus is downgraded from a distinct species to subspecies P. marginatus subrugosus stat. nov. This species was recorded from the summit of Mt. Rishiri-dake based on two female specimens ( Morita 1995, as P. subrugosus ). However, the subspecies identity of the Rishiri population remains undetermined because specimens from the locality were not examined in this study.
