Abstract

Two new species of blind cavernicolous ground beetles in the genus Anillinus Casey are described from Texas. Based on the structure of the male genitalia, Anillinus reddellisp. nov. (type locality: SW Bypass Cave, Williamson County, Texas) is closely related to A. forthoodensis Sokolov and Reddell from the neighboring Bell County. Based on the structure of the male genitalia, Anillinus bexarensissp. nov. (type locality: Up the Creek Cave, Bexar County, Texas) is closely related to A. weismanensis Sokolov and Kavanaugh from Hays and Bell Counties. Both new species are illustrated with images of the habitus, body parts, and male and female genitalia. Based on morphological data a new grouping of the Texas species is proposed and discussed.
