Bembidion ephippigerum (LeConte, 1852)

Ochthedromus ephippiger LeConte, 1852a: 188. Type locality: "San Diego [San Diego County, California]" (original citation). Two syntypes in MCZ [# 5542]. Note. According to ICZN (1999: example for Article 31.2.2), names ending in - fer and - ger may be nouns in apposition (e.g., Bembidion ephippiger ) or adjectives in the masculine gender (e.g., Bembidion ephippigerum ). In such case the name is to be treated as a noun in apposition unless the author indicated that the name was an adjective or the evidence of usage is decisive. LeConte (1852a: 188) did not specify that the name was an adjective but the evidence of usage is decisive because the name has been treated as an adjective since Leng (1920: 51).

Distribution.

This species is confined to the west coast ranging from Vancouver Island (Lindroth 1963b: 345) to southern California (LeConte 1852a: 188; Fall 1901a: 42). The records from “Montana,” “Wyoming,” “Utah,” “Arizona” (Hayward 1897: 111), and “Colorado” (Csiki 1928: 118) almost certainly refer to Bembidion salinarium Casey.
