Bembidion impotens Casey, 1918

Ochthedromus pictus LeConte, 1847: 461 [secondary homonym of Bembidion pictum (Duftschmid, 1812)]. Type locality: "Rocky Mountains" (original citation). Syntype(s) in MCZ [# 5537].

Emphanes flavopictus Motschulsky, 1858: 153. Replacement name for Emphanes pictus (LeConte, 1847). Note. This name was first introduced by Motschulsky (1850a: 13) in a catalogue but the taxon was not described. Subsequently Motschulsky (1858: 153) listed the name in synonymy with Ochthedromus pictus LeConte and pointed out that since LeConte’s name was preoccupied, his name could be preserved. In my opinion such statement should be interpreted as the introduction of a replacement name. Casey (1918: 135) eventually described Bembidion flavopictum Motschulsky from the "coast region, from S[an]ta Cruz to Humboldt, California." This name should have precedence over Bembidion impotens Casey, 1918 but since Casey’s name has been used as valid since the 1920s, I believe it should be preserved and the case eventually submitted to the Commission for a ruling. The reversal of precedence (ICZN 1999: Article 23.9.1) could not be applied since Motschulsky’s name has been used as a valid name after 1899 by Casey (1918: 135).

Bembidion frugale Casey, 1918: 130. Type locality: "Yuma Reservation, California" (original citation). Lectotype (♂), designated by Erwin (1984a: 174), in USNM [# 37006]. Synonymy established by Erwin (1984a: 174).

Bembidion imbelle Casey, 1918: 130. Type locality: "Dallas [Dallas County], Texas" (original citation for the lectotype). Lectotype (♂), designated by Erwin (1984a: 174), in USNM [# 37007]. Synonymy established by Erwin (1984a: 174).
