Interpretive Summary: Ground beetles are among insects important for U.S. agriculture. Many are predators of exotic pests that can be used as biological control agents while some are serious pests themselves destroying valuable crops costing millions of dollars annually. This work documents a discovery of two ground beetle species previously unknown to science. The species are described, illustrated and compared to known species of the genus. The study will be useful to biological control workers, evolutionary biologists, ecologists, and anyone interested in predatory beetles.

Technical Abstract: Two new species of blind ground beetles are described from the southern United States. One species, Anillinus relictus n. sp. (type locality: E of Oneonta, Blount County, Alabama), based on the structure of male genitalia, is similar to Texan Anillinus, in particular to endogean A. sinuatus Jeannel. The second species, A. felicianus n. sp. (type locality: 4mi SW Jackson, West Feliciana Parish, Louisiana), superficially, is similar to endogean A. sinuaticollis Jeannel from Roane County, Tennessee, and represents a new genus state record for Louisiana. All species are illustrated with digital images of habitus, body parts, and male and female genitalia. Biogeographical and evolutionary implications of new findings are discussed.
