The first endemic species of Camillidae are described from the New World and the Nearctic Region. Three new species are described: Afrocamilla arizona (south-eastern Arizona); A. bispinosa (southern California); and Camilla arnaudi (Baja California, Mexico). All species are illustrated and a key to the endemic Nearctic species of Camillidae is presented. Camilla glabra (Fallen, 1823), previously introduced to Canada from Europe, is Likely to be no longer extant in the Nearctic Region. The biology of Camillidae is briefly reviewed.
