Notes.

Fassati (1957) describes Bembidion (Peryphus) fuscicrum thibeticum   ssp. nov. and Bembidion (Peryphus) fuscicrum fumipenne   nat. nov.; they are distinguished from the nominotypical form only by the coloration of the elytra. Lindroth (1963) synonymizes the following taxa with B. obscurellum   Motschulsky, 1845: B. fuscicrum   Motschulsky, 1855, B. fuscicrum turanicum   Csiki, 1928, B. fumipenne   and B. thibeticum   , the last two taxa because they are only color varieties. Kryzhanovskij et al. (1995) listed B. turanicum   as a subspecies of B. obscurellum   and retained B. fumipenne   and B. thibeticum   as varieties only; moreover Belousov’s note (Kryzhanovskij et al. 1995: 85, note no. 158) reports that the subspecific situation of this polymorphic species is provisional. Recently, some authors (e.g., Lorenz 2005; Marggi et al. 2017) still list B. turanicum   , B. fumipenne   , and B. thibeticum   as subspecies of B. obscurellum   .

In light of our studies we maintain that the synonymies proposed by Lindroth (1963) were correct; moreover, our colleague Liang Hongbin (IZCAS, Beijing) confirms our opinion based on the study of hundreds of specimens from Mongolia that clearly show the variability of the species (Liang Hongbin, pers. comm.).

Regarding Bembidion (Peryphus) obscurellum insperatum   Lutshnik, 1938, since its discriminating characters are not exclusive but shared by other subspecies, we evaluated the synonymy expressed in Marggi et al. (2017) and add to the distribution of the species the Russian Caucasus (ST), the region mentioned in the description, as already reported in Kryzhanovskij et al. (1995): Ciscaucasia, Western and Central Greater Caucasus. Current distribution: E: DE, NT, ST, SV; A: AF, CH, ES, IN, KA, KI, KZ, MG, TM, TR, WS, XIZ; NAR.
