Dyschirius convexus LeConte, 1852a: 195. Type locality: "San Diego [San Diego County, California]" (original citation). Syntype(s) in MCZ [# 687]. Synonymy established by LeConte (1858a: 29), confirmed by Lindroth (1961a: 138).

Dyschirius quadridens Motschulsky, 1859a: 133. Type locality: California (inferred from title of the paper). One syntype, listed as “corruptum,” in ZMMU (Keleinikova 1976: 213). Synonymy established by LeConte (1863b: 3).

Distribution.

This species is found from northern Washington (Lindroth 1961a: 138) to western Montana (Russell 1968: 47), south to southwestern New Mexico (Sierra County, CMNH) and southwestern California (LeConte 1852a: 195; Moore 1937: 5). The records from “Nebraska” (Bousquet and Larochelle 1993: 98) and northwestern British Columbia (Hatch 1953: 67) are probably in error. One old specimen simply labeled “Van” is known (MCZ).
