Description
Summary:Pterostichus ( Lenapterus ) marginatus Matsumura, 1911 Fig. 3 Pterostichus marginatus : Matsumura (1911): 111 (original description), type locality: “Tonnaitcha, Ushoro” [written as “Oshiyoro” on the labels of syntypes, but both corresponding to the same locality, Okhotskoe, southern Sakhalin]; Bousquet (2003): 515; Bousquet (2017): 747. Pterostichus ( Lyperopherus ) subrugosus : Straneo (1955) (original description): 88, type locality “M. Daisetsu, Hokuchindake” [Mt.

Pterostichus ( Lyperopherus ) wellschmiedi : Kirschenhofer (1985): 224 (original description), type locality: “Süd-Sachalin, Umgeb. Nowoalexandrowsk, Berg Tschkowa” [Mt. Chekhov, southern Sakhalin]. Syn. nov. Pterostichus ( Lenapterus ) subrugosus : Morita (1995): 4; Bousquet (2003): 497. Pterostichus ( Steroperis ) wellschmiedi : Kryzhanovskij et al. (1995): 105. Pterostichus ( Lenapterus ) wellschmiedi : Berlov & Berlov (1997d): 39; Bousquet (2003): 497 (synonym of subrugosus ); Bousquet (2017): 718. Materials examined.

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. : Published as part of Sasakawa, Kôji, Berlov, Oleg & Okuzaki, Yutaka, 2020, Taxonomic and nomenclatural changes in three species of Pterostichus Bonelli (Coleoptera: Carabidae) from the Far East, pp. 416-424 in Zootaxa 4822 (3) on page 420, DOI: 10.11646/zootaxa.4822.3.6, http://zenodo.org/record/4401755 : {"references": ["Matsumura, S.
