Abstract
New distribution records of six species of Japanese Phygadeuontinae, Acrolyta spola Momoi, 1970 (from Tokunoshima Is.), Diatora lissonota (Viereck, 1912) (from Tokunoshima Is.), Mastrus oshimensis (Uchida, 1930) (from Honshu), Phygadeuon elongatus (Uchida, 1930) (from Honshu), P. yonedai Kusigemati, 1986 (from Honshu and Izuoshima Is.), and Theroscopus maruyamanus (Uchida, 1930) (from Honshu), are recorded. These species except A. spola and P. yonedai are re-described. In addition, P. akaashii Uchida, 1930 and T. fukuiyamensis (Uchida, 1936) are also re-described. Mastrus oshimensis and T. maruyamanus have only been recorded in the original description and these are the second record for both species.
