Eight species, P. akaashii Uchida, 1930 , P. bidentata ( Uchida, 1930) , P. elongatus ( Uchida, 1930) , P. kiashii Uchida, 1930 , P. kochiensis Uchida, 1936 , P. sapporoensis (Ashmead, 1906) , P. similis ( Uchida, 1930) , and P. yonedai Kusigemati, 1986 , have been recorded from Japan. I found more than 20 undetermined species from Japan. The taxonomic treatment of these species requires the additional specimens and comparison with European species. In this study, I re-describe P. akaashii and P. elongatus and record some distribution data of these species and P. yonedai .
