Genus Synuchus Gyllenhal, 1810

Synuchus Gyllenhal, 1810: 77. Type species: Carabus nivalis Panzer, 1796 (= Carabus vivalis Illiger, 1798) by monotypy. Etymology. Probably from the Greek synochos (join, continued) rather than from the Greek prefix syn- (together, with) and onyx, - ychos (claw) [masculine].

Taphria Dejean, 1821: 10. Type species: Carabus vivalis Illiger, 1798 by monotypy. Etymology. From the Greek taphros (ditch, trench, by extension stria, dimple) [feminine]. This name was proposed by Franco Andrea Bonelli and made available by Dejean.

Pristodactyla Dejean, 1828: 82. Type species: Pristodactyla americana Dejean, 1828 (= Feronia impunctata Say, 1823) by monotypy. Synonymy established by Lindroth (1955a: 115). Etymology (original). From the Greek pristes (sawyer) and dactylos (finger), alluding to the denticulate claws (" crochets des tarses dentelés en-dessous ") of the adult [feminine].
