Ardistomis is a of pedunculate ground beetles (Carabidae: Scaritinae) comprising more than 40 described distributed across North, Central, and South America. Larval supports classification of ardistomines (Ardistomis, Semiardistomis, and Aspidoglossa) as a subtribe (Ardistomina) within the tribe Clivinini. The genus includes species with documented range extensions, such as A. quixotei, which likely colonized Cuba from Mexico during the .

Identification

Members of Ardistomis can be distinguished from other clivinine by features of the male genitalia; for West Indian , diagnostic keys are available. The genus is characterized by pedunculate body form typical of the subtribe Ardistomina. Species-level identification requires examination of genitalic structures and comparison with described type material.

Habitat

Specific associations have been documented for some ; Cuban of A. quixotei have associated natural history data, though detailed habitat descriptions are not specified in available sources. As ground beetles, species likely occur in soil and leaf litter environments.

Distribution

Widespread in the Western Hemisphere, with documented in North America, Central America, South America, and the West Indies (including Cuba).

Life Cycle

Complete with documented larval and pupal stages for at least one (A. quixotei); larval has been used to support higher-level classification within Clivinini.

Taxonomic Classification

Larval morphological features support recognition of ardistomines (Ardistomis, Semiardistomis, and Aspidoglossa) as the subtribe Ardistomina within tribe Clivinini, rather than as a separate tribe.

Biogeographic History

At least one , A. quixotei, appears to have extended its geographic range from Mexico to Cuba during the , suggesting active and dynamics in the .
