Subgenus Trichoplataphus Netolitzky, 1914

Trichoplataphus Netolitzky, 1914: 51. Type species: Bembidium lissonotum Bates, 1873 designated by Netolitzky (1943a: 109). Etymology. From the Greek trichos (hair) and the generic name Plataphus [q.v.], alluding to the presence of sparse setae on the metasternum, metacoxae, and abdominal sterna (" die schüttere Behaarung des Metasternums, der Hinterhüften und aller sichtbaren Ventralsegmente ") on the adults of these Plataphus- related species [masculine].

Triporus Andrewes, 1921: 251. Type species: Bembidium kara Andrewes, 1921 by monotypy. Synonymy established by Netolitzky (1943a: 109). Etymology. From the Latin prefix tri - (three) and porus (holes), alluding to the presence of three discal setigerous punctures on the third elytral interval ("elytra ... stria ... 3 with three well-marked pores") of the adult [masculine].

Diversity.

Northern Hemisphere, with 22 species in the Nearctic (five eastern species) and Palaearctic (17 Asian species) Regions (see Toledano and Schmidt 2010).

Identification.

Four of the North American species are included in Lindroth’s (1963b: 212-229) key to species of Bembidion ; three of these were treated in detail (Lindroth 1963b: 298-300). One new species was described subsequently by Hildebrandt and Maddison (2011) who provided a modified version of Lindroth’s key to include the new species.
