Type locality: "Vancouver Island [British Columbia]" (original citation), herein restricted to Duncan (CNC). Holotype (♂) in MCZ [# 23862]. Note. The name  Bembidion hesperiumhas been credited to Casey (1918: 9) by some authors on the basis that Casey proposed a replacement name for  Bembidium hesperumFall, 1910, supposedly a junior primary homonym of  Bembidion hesperusCrotch, 1867. In fact, Casey (1918) emended Fall'sname to  Bembidion hesperiumsince the name  Bembidion hesperumis an incorrect latinization for  Bembidion hesperium(adjective) or  Bembidion hesperus(noun in apposition). Casey'semendation is currently in prevailing usage and so deemed to be a justified emendation (ICZN 1999: Article 33.2.3.1).  Bembidion binariumCasey, 1918: 9.
