''Anillinus'' is a genus in the

ground beetle Ground beetles are a large, cosmopolitan distribution, cosmopolitan family (biology), family of beetles, the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. As of 2015, it ...

family Carabidae. There are more than 60 described species in ''Anillinus'', from the southeastern United States. They range from the east coast as far west as Texas and Oklahoma. Two species, ''Anillinus magnus'' and ''Anillinus minor'', have been described from Brazil, although validity of these species has been questioned. Like other members of the subtribe Anillina, the species of ''Anillinus'' are blind, wingless, and small, typically 3 mm long or less. They live in deep forest litters, under rocks or in soil, or in caves as true

troglobite A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves. These are separate from species that mainly live in above-ground habitats but are also able to live u ...

s. ''Anillinus'' species tend to have extremely localized distributions, with a relatively large number of species in a few states. They have a geologically recent history of lineage diversification. This provides a valuable source of biogeographic information used in modeling evolutionary systems of regional biotas. The genus ''Anillinus'' remains one of the most incompletely known genera of ground beetles in the United States. In just the 20 years from 2003 to 2023, the number of known species of ''Anillinus'' increased from 11 to 63 species.
