Review of the species of Ardistomina (Coleoptera: Carabidae: Clivinini) in America north of Mexico

North American species of the genera Aspidoglossa Putzeys, Semiardistomis Kult and Ardistomis Putzeys, which constitute the subtribe Ardistomina in the tribe Clivinini, are reviewed. The five species are keyed, redescribed and notes are provided about their distribution and habitat requirements. Larval character states of the subtribe are described for the first time based on first instar of Semiardistomis viridis (Say). Illustrations of some of the most important morphological features as well as distribution maps are included. The species known as Ardistomis morio (Dejean) is redescribed from the holotype. Evidence is presented which establishes that this species does not belong to the genus Ardistomis, or to the subtribe Ardistomina, and that the sole specimen known was probably collected in the Neotropical Region, not in the Nearctic Region. The species is returned to the genus Clivina in which it was originally described.
