Fore wing ( Fig. 25a) 2.2× as long as wide; costal cell 8.0× as long as wide, on upper surface with a setal row in distal half, on lower surface with a complete setal row and scattered setae apically; basal cell closed, with a few setae; cubital setal line present; basal setal line present; speculum opened below; relative lengths of marginal vein: postmarginal vein: stigmal vein=9.6: 2.4: 1.0. Hind coxa 2.0× as long as wide, with dorsal carina basally; dorsal surface of hind coxa setose; hind femur 3.9× as long as wide; hind tibia with longer spur 1.3× as long as width of hind tibia, 0.5× length of basitarsus; shorter spur 0.7× length of longer spur. Metasoma as long as mesosoma; posterior margin of metasomal tergum five entire; tip of hypopygium situated at 0.8 length of metasoma; ovipositor sheath as long as metasoma, 1.5× as long as hind tibia.  Male.Differs from female as follows. Body length 1.7 mm. Antenna stouter than that of female ( Fig. 6f); pedicel 1.4× as long as wide; F1–F7 0.5–0.7× as long as wide.   Distribution. Japan( Hokkaido).   Host information.  Torymus minamiiis a parasitoid of  Kiefferia pericarpiicola(Bremi)( Diptera: Cecidomyiidae) on  Angelica sachalinensisMaxim. var. sachalinensis(Apiaceae),  A. edulisMiyabe ex Y. Yabe(gall photo: fig. 27c), and  Spuriopimpinella calycina(Maxim.) Kitag. (Apiaceae).   Remarks.Females of  T. minamiiare similar to  T. sasaeMatsuobecause of the following shared features: scutellum sculptured as posterior part of mesoscutum; dorsellum without median carina; propodeum with superficial reticulation, smoother medially; speculum narrowly opened below; dorsal surface of hind coxa setose in basal half. However, females of  T. minamiican be distinguished from  T. sasaeby having the following features: scape not reaching anterior ocellus (just reaching ventral margin of anterior ocellus in  T. sasae); each funicular segment bearing longitudinal sensilla arranged in one row (two rows in  T. sasae); posterior margin of metasomal tergum five entire (incised in  T. sasae); tip of hypopygium situated at 0.8 length of metasoma (0.6 length of metasoma in  T. sasae); ovipositor sheath as long as metasoma, 1.5× as long as hind tibia (2.3× as long as hind tibia in  T. sasae).
