New or poorly known Palaearctic pselaphids (Coleoptera: Staphylinidae: Pselaphinae)

One genus (Thelotia gen. n.) and ten new species are described: Octomicrus dentifrons sp. n. from Iraq, Faronus distinctus sp. n. from Turkey, Thelotia cebennica sp. n. from France, Amauronyx caudatus sp. n. from Yugoslavia, Namunia terricola sp. n. from Greece, Bryaxis corsus sp. n. from Corsica, Trissemus bellax sp. n. from Spain, T. sulcifrons sp. n. from Morocco, T. trilobatus sp. n. and T. holzschuhi sp. n. from Pakistan. Trichonychini, Dimerus and six species are placed in synonymy. A neotype of Bryaxis opuntiae Schmidt-Gobel and lectotypes of Rybaxis marquardti Reitter and Bythinus banaticus Reitter are designated. Transfers of three species are proposed and new distributional records of Octomicrus staphylinoides (Fiori) are provided.
