Allantus nigripectus Matsumura, 1912 is synonymized with Allantus flavipectus Matsumura, 1912, because the color characters used to separate them have been found variable and the two taxa are not separable. Tenthredo nigripleuris (Enslin, 1910) is newly recorded from Japan based on the specimens previously identified with "T. devius". There is no evidence for the occurrence of Tenthredo devia (Konow, 1900) in Japan. Japanese populations of Tenthredo colon Klug, 1817 have been called "T. colon nigriventris Enslin, 1912" in Japanese literature but this usage of the subspecific name is erroneous. It is proposed not to recognize a subspecific taxon for Japanese populations until more is known about the geographic variations of this widely distributed Holarctic species. Tenthredo babai Takeuchi, 1936, previously known only from Honshu and Sado Island, is newly recorded from Kyushu.
