Distribution.

This species is found from Skamania County in southern Washington (Hatch 1953: 93, as Bembidion stevensoni ) to the San Diego area in southwestern California (LeConte 1852a: 187; Moore 1937: 7). The records from Nevada (Bechtel et al. 1983: 474), "British Columbia," “Arizona,” “Dacota” (Hayward 1897: 99), and northern Idaho (Hatch 1953: 93) are likely based on misidentified specimens (see Lindroth 1963b: 359).
