Subgenus Diplocampa Bedel, 1896

Diplocampa Bedel, 1896: 56, 70. Type species: Bembidium assimile Gyllenhal, 1810 designated by Jeannel (1941b: 462). Etymology. From the Greek prefix diplo - (double) and the generic name Campa , alluding to the frontal sulcus being dou ble (" les bourrelets frontaux sont dédoublés ") in the adult [feminine]. Note. Bedel (1896: 56) originally included two species in his new genus-group taxon: Bembidion assimile Gyllenhal and Bembidion fumigatum (Duftschmid).

Paralopha Casey, 1918: 153 [junior homonym of Paralopha Bethune-Baker, 1908]. Type species: Ochthedromus sulcatus LeConte, 1847 (= Peryphus transparens Gebler, 1830) by original designation. Synonymy established by Netolitzky (1931: 164). Etymology. From the Greek para (near, next to) and the generic name Lopha [q.v.] [feminine].

Diversity.

Northern Hemisphere, with eight species in the Nearctic (one Holarctic species) and Palaearctic (eight species) Regions.

Identification.

Lindroth (1963b: 393-395) covered the North American species in his monograph of the Canadian and Alaskan Carabidae .

Taxonomic Note.

One species ( Bembidion longipenne Putzeys) from Venezuela is currently included in this subgenus but is probably not consubgeneric with members of Diplocampa . Bembidion hesperus Crotch, described from the Azores and listed in this subgenus by Lorenz (2005: 223), is a junior synonym of Bembidion ambiguum Dejean (Lindroth 1960b: 6), a species of the subgenus Neja Motschulsky.
