Subgenus Agostenus Fischer von Waldheim, 1829

Agostenus Fischer von Waldheim, 1829a: 15. Type species: Carabus sulcicollis Paykull, 1798 designated by Jeannel (1942: 971). Etymology. Uncertain, possibly from the Greek agon (gathering) or agos (leader) or the incorrect transcription of agan (very) and stenos (narrow, tight) [masculine]. The name was proposed by Franz Anton Ziegler and made available by Fischer von Waldheim. Note. This name has been incorrectly credited to Motschulsky (1850a: x, 65) until Kryzhanovskij et al. (1995: 158).

Pelasnus Fischer von Waldheim, 1829a: 15. Type species: Carabus quadrisulcatus Paykull sensu Illiger, 1798 (= Agostenus costulatus Motschulsky, 1859) by monotypy. Note. This name has been incorrectly credited to Motschulsky (1850a: x, 65, as Pelasmus ) until Kryzhanovskij et al. (1995: 158).

Agostenops Lutshnik, 1933b: 171. Type species: Chlaenius alutaceus Gebler, 1830 by monotypy. Synonymy established by Kryzhanovskij et al. (1995: 158). Etymology. From the generic name Agostenus [q.v.] and the Greek suffix - ops (having the appearance of) [masculine].

Nine species in the Nearctic (five species), Neotropical (one Mexican species also found in Arizona), and Palaearctic (four species) Regions.
