Genus Anisodactylus Dejean, 1829

Anisodactylus Dejean, 1829: 4, 132. Type species: Carabus binotatus Fabricius, 1787 designated by Westwood (1838: 4). Etymology. From the Greek anisos (unequal) and dactylos (finger), probably referring to the fact that the male protarsomere 1 is distinctly smaller than the following three (" premier article des 4 tarses antérieurs des mâles plus petit que les suivants ") in the species that Dejean included in this taxon [masculine].

About 50 species in North America (33 species, one of them adventive), Mexico (seven species, two of them endemic), and the Palaearctic Region (17 species) arrayed in nine subgenera: Anadaptus (seven species), Anisodactylus s.str. (22 species), Aplocentrus (two species), Gynandrotarsus (10 species), Hexatrichus Tschitschérine (four west Palaearctic species), Pseudanisodactylus Noonan (three Palaearctic species), Pseudaplocentrus (one species), Pseudodichirus Lutshnik (one west Palaearctic species), and Spongopus (one species). One Palaearctic species ( Anisodactylus binotatus ) is adventive in New Zealand (Larochelle and Larivière 2005: 34).
