Genus Bembidion Latreille, 1802 

Bembidion  Latreille, 1802: 82. Type species: Carabus quadriguttatus  Fabricius, 1775 (= Cicindela quadrimaculata  Linnaeus, 1760) designated by Andrewes (1935: 17). Etymology. From the Greek bembix (whirl, top) and the suffix -idion (little), probably alluding to the erratic movements of adults of these small species in the field [neuter]. Note. Notwithstanding Maddison’s (1993: 151) remarks and Toledano’s (1999: 197-199) lengthy discussion, the first valid type species designation for Bembidion  Latreille, 1802 is that of Andrewes (1935: 17) who designated Cicindela quadrimaculata  Linnaeus, 1760. Even if this species was not an originally included species, the fact that Andrewes (1935: 17) listed it in synonymy with Carabus quadriguttatus  Fabricius, 1775, a species originally included, he is deemed to have designated the latter species as type species (ICZN 1999: Article 69.2.2).

Diversity.

Worldwide, with about 1,250 species (Lorenz 2005: 215-236, as Bembidiina  excluding Phrypeus  , Amerizus  , Lionepha  ,and Asaphidion  ) arrayed in about 105 subgenera. The Northern Hemisphere includes roughly 75% of the species and the Westhern Hemisphere approximately 30% of the species. The North American fauna alone is represented by 253 species (about 20% of the world fauna) placed in 37 subgenera. Eight of the North American species are adventive and 20 species are Holarctic.

Identification.

Hayward (1897) reviewed the North American species but his work is now outdated. Lindroth (1963b) covered 191 (six of them in the key alone) of the 253 species found in North America (about 75% of the fauna).

Taxonomic Note.

Maddison (2012: 570) presented an entirely new classification of this genus based on molecular data analyses. He found support for monophyly of Bembidion  exclusive of the subgenus Phyla  ; however, he retained the taxon in the genus pending further study. He recognized three series, the Odontium  , Ocydromus  , and Bembidion  Series with the following subgenera represented in North America left unplaced: Blepharoplataphus  , Plataphus  (including Plataphodes  ), Hydrium  (including Eurytrachelus  ), Metallina  , Lindrochthus  , Eupetedromus  , Trechonepha  , Liocosmius  , Melomalus  , Trichoplataphus  , Phyla  , and Lymnaeum  . The North American taxa in the Odontium  Series were placed in two complexes, the Hydriomicrus  ( Hirmoplataphus  and Hydriomicrus  ) and Odontium  ( Odontium  , Bracteon  , Ochthedromus  , and Pseudoperyphus  ) Complexes. The North American taxa in the Ocydromus  Series were placed in two complexes, the Princidium  ( Cillenus  and Actedium  ) and Ocydromus  ( Ocydromus  , Peryphus  , Terminophanes  , Asioperyphus  , Peryphanes  , Testediolum  , and Leuchydrium  ) Complexes. The North American taxa in the Bembidion  Series were placed in three complexes, the Bembidion  ( Bembidion  s.str. and Cyclolopha  ), Furcacampa  ( Furcacampa  and Neobembidion  ) and Diplocampa  ( Diplocampa  and Semicampa  ) Complexes with Notaphus  , Trepanedoris  , Peryphodes  , and Emphanes  left unplaced.

Faunistic Note.

Edwards (1975: 53) recorded a " Bembidion nigricornis  Hayward" from Glacier National Park in Montana. I was unable to find any Bembidion  of that name or with a similar name described by Hayward or any other North American authors.
