Staines 3302 Decker Place Edgewater, Maryland 21 037 U.S.A. Abstract The pilatei species group of Anisostena s. str. is revised. Lectotoypes are designated for A. nunenmacheri, A. pilatei, and A. trilineata; A. mitchelli is synonymized with A. arizonica; A. confusa and A. vittata are described as new. Key words: Anisostena, lectotype, revision, new species. Introduction 2.
