Genus Pterostichus Bonelli, 1810

Pterostichus Bonelli, 1810: Tabula Synoptica. Type species: Carabus fasciatopunctatus Creutzer, 1799 designated by Curtis (1828: plate 196). Etymology. From the Greek pteron (wing, by extension elytron) and stichos (row, line), possibly alluding to the striae on the elytra of the adults [masculine].

Diversity.

About 1,055 species (Lorenz 2005: 269-287, 289, as Pterostichus , Lyropedius , and Abacidus ) in the Nearctic (about 180 species, of which four are adventive) and Palaearctic (about 875 species) Regions. Percolaus Bates with two Middle American species, Mayaferonia Ball and Roughley with two Middle American species, and Allotriopus Bates with eight Mexican species are also includes in the genus Pterostichus by some authors (e.g., Ball and Roughley 1982).

Faunistic Note.

Pterostichus (Steropus) madidus (Fabricius), a European species, is known in North America from two specimens, one collected in 1913 in Quebec (Lindroth 1966: 476) and the other one in 1984 in Somerset County, Pennsylvania (Cameron and Reeves 1990: 127). Until more specimens are collected on this continent, the species is not considered as a North American resident.

Taxonomic Note.

Based on phylogenetic analyses from two nuclear gene sequences (wingless and 28SrDNA), Sasakawa and Kubota (2007) concluded that the genus Pte rostichus sensu Bousquet (1999) was monophyletic with the exception of Bothriopterus which forms a clade with Stomis and Myas .
