Notes.

The subgenus Bembidion Politophanes Müller-Morzfeld, 1998 was restored by Schmidt (2018), after Toledano (2008) downgraded Politophanes to species group of subgenus Ocydromus Clairville, 1806. The subgenus includes the species that show particular endophallic characters (main sclerite from slightly arcuate to clearly bent, S-shaped, even long and coiled in a ring in the central portion in some species). Bembidion chloreum , currently listed as member of subgenus Bembidion Peryphus , shows endophallic characters that clearly include it in the subgenus Bembidion Politophanes .

Bembidion sapporense Jedlička, 1951, currently assigned to the subgenus Bembidion Asioperyphus Vysoký, 1986, was described from a single male specimen: we examined the holotype (NMPC) and, based on the aedeagal characters (long main sclerite, coiled in a ring at middle) we assign it to the subgenus Bembidion Politophanes . The labels of the specimen (Fig. 4 ) show that our colleague Seiji Morita (Tokyo), a specialist in Japanese Carabidae , particularly in the Bembidiina , identified the specimen as Bembidion chloreum Bates in 1991. Later he confirmed this identification and authorized us to state it formally here (Morita, pers. comm.): we are very grateful for that. Therefore we state the following synonymy: Bembidion (Asioperyphus) sapporense Jedlička, 1951 = Bembidion (Politophanes) chloreum Bates, 1873 syn. nov.
