Five new species of Japanese spiders of the families Dictynidae, Cybaeidae, Coelotidae and Ctenidae (Arachnida, Araneae) are reported. Adenodictyna kudoae sp. nov. (Dictynidae) is described from Amami-o-shima Island, Kagoshima Prefecture, and designated as the type species of a monotypic new genus, Adenodictyna gen. nov. A cavernicolous spider, Cybaeus inagakii sp. nov. (Cybaeidae) is described from Kurotengu-no-ana Cave in Mie Prefecture, Honshu. Two new species of the family Coelotidae (=Coelotinae : Wang, 2002), Coelotes hachijoensis sp. nov. (from Hachijo-jima Island, Tokyo) and Tegecoelotes mizuyamae sp. nov. (from Ibaraki Prefecture) are described. The former species is regarded to be derived from Coelotes exitialis L. Koch, 1878, widely distributed in Honshu, while the latter is a sister species of northern Japanese Coelotes erraticus Nishikawa, 1983, which is revived from the synonymy of Tegecoelotes secundus (Paik, 1971) recorded from Korea and Russia. An oceanic spider, Acantheis nipponicus sp. nov. (Ctenidae), is described from Minami-io-to (=Minami-iwo-jima) Island, Tokyo. The genus Acantheis Thorell, 1891, originated in Southeast Asia, is recorded from Japan for the first time.
