Abstract: The monospecific clavigerite genus Archiclaviger Heller, 1936 (Coleoptera: Staphylinidae: Pselaphinae), previously only known from Java, is reported to occur in China. A new species, A. gaofani sp. nov., was collected in nests of Nylanderia Emery, 1906 ants (Hymenoptera: Formicidae) in Jiangsu Province, and is described here. The new species can be separated from A. overbecki Heller, 1936 by different proportions of the antennomeres, and much sparser setae at the apex of the elytra and base of the abdomen. A revised diagnosis of Archiclaviger is provided, and a lectotype is designated for A. overbecki.
Key words: Coleoptera, Staphylinidae, Pselaphinae, Clavigeritae, Archiclaviger, lectotype designation, range extension, Nylanderia ant, myrmecophily, China, Asia
