A revision of Nearctic species of the genus Tropimenelytron Pace, 1983 (Coleoptera: Staphylinidae: Aleocharinae), a new genus for North America

Abstract

Nearctic species of the genus Tropimenelytron Pace, 1983, a new genus for North America, are revised. Redescription and illustrations are provided for distinguishing the genus Tropimenelytron from other related aleocharine genera. Three new species are described: T. americanum Gusarov, sp. n., from Indiana, Wisconsin, Iowa, Missouri, Ohio, Pennsylvania, New York, Connecticut and Quebec; T. robustum Gusarov, sp. n., from Oregon and British Columbia and T. californicum Gusarov, sp. n. from California. A key for identification of Nearctic species of Tropimenelytron is provided. The status of the genus Pelioptera Kraatz, 1957 is discussed. Pelioptera unica (Bernhauer, 1907) from Japan and P. peguana (Bernhauer, 1915) from Burma are transferred to Tropimenelytron.
