Genus
Agonum Bonelli, 1810
Agonum
Bonelli, 1810: Tabula Synoptica. Type species:
Carabus marginatus
Linnaeus, 1758 designated by Curtis (1827: plate 183). Etymology. Uncertain, possibly from the Greek
a
(without) and
gonia
(angle), alluding to the rounded posterior angles of the pronotum ("
th
[
orax
] ...
angulis baseos rotundatis
") of the adult or from the Greek
agonos
(barren), or from the Greek
agon
, -
os
(contest, struggle) [neuter].
Amolyntus
Gistel, 1848a: viii. Unnecessary replacement name for
Agonum
Bonelli, 1810.
Agonothorax
Motschulsky, 1850a: 67. Unnecessary replacement name for
Agonum
Bonelli, 1810.
Diversity.
About 130 species (Liebherr and Schmidt 2004: 202-203) in the Nearctic (72 species, one adventive), Neotropical (15 species in Middle America, all but two shared with North America), Palaearctic (63 species, of which seven are Holarctic), and Afrotropical (three endemic species) Regions. The species are arrayed in four subgenera, following Liebherr and Schmidt (2004):
Europhilus
,
Platynomicrus
,
Agonum
s.str., and
Olisares
, all represented in North America. All other subgenera of
Agonum
listed in Lorenz (2005: 411-412) have been excluded by Liebherr and Schmidt (2004: 152) as most of them "are most likely evolutionary affiliates of the highly diverse and taxonomically confused
Platynus
-"
Colpodes
" group of genera." About 50 species are left unplaced in Lorenz (2005: 412) and some of them may belong to
Agonum
.
Identification.
Liebherr (1994) published a key to all species found in the Western Hemisphere as well as a review of the Middle American species. Lindroth (1966, 1969a) covered all North American species except
Agonum anthracinum
Dejean,
Agonum cyanopis
Bates,
Agonum elongatulum
Dejean,
Agonum extimum
Liebherr,
Agonum muiri
Liebherr,
Agonum pacificum
Casey, and
Agonum parextimum
Liebherr.
