Distribution.

This species ranges from Newfoundland (Lindroth 1955a: 59) to Alaska (Maddison and Swanson 2010: 27), south to southern California (LeConte 1852a: 190; Maddison 1985: 114), “Utah,” “Colorado” (Maddison and Swanson 2010: 27), northern Michigan (Hubbard and Schwarz 1878: 629; Dunn 1985a: 10; CNC), and central New York (Notman 1928: 215). The record from South Dakota (Kirk and Balsbaugh 1975: 17) refers to Bembidion mexicanum (USNM); thatfrom “Illinois” (Bousquet and Larochelle 1993: 138) needs confirmation.

Note.

Maddison and Swanson (2010: 27) stated that specimens of this species from western British Columbia, western Oregon, and California represent another form, with no consistent differences in COI or 28S from the typical form but with clearly different mentum shape. They added that Bembidion transversale as currently understood could be a complex of multiple species.
