A total of 78 Japanese species belonging to the family Tetranychidae (spider mites) are assigned to two subfamilies, five tribes, 16 genera, and 13 species groups (only in four genera). A guide to identification of the Japanese species is provided, and information is also given about the important literature references, host plants, and distribution of each species. Three new species, Eotetranychus rubricans, Oligonychus gotohi, and Tetranychus parakanzawai are described. Eotetranychus lewisi (McGregor), recently recorded from Japan, is redescribed.
