Lirceus usdagalun new species, the first known troglobitic species of the genus, is described from three caves in Lee County, Virginia. The potential taxonomic value of the endopod tip of the male second pleopod, heretofore dismissed as a diagnostic character in this genus, is pointed out. Some general ecological data for the new species are presented, and cave records for other populations of Lirceus spp. from the Appalachians are given.
