FIGURE 16 a–b. T. minamii ♀. a , mesoscutum, dorsal view; b , scutellum, dorsal view. Mesosoma 1.5× as long as wide; mesoscutum ( Fig. 16a ) transversely reticulate; notaulus shallow; scutellum ( Fig. 16b ) 1.3× as long as wide, sculptured as posterior part of mesoscutum; dorsellum without median carina; propodeum ( Fig. 16b ) with superficial reticulation, smoother medially; lower mesepimeron 1.4× as long as wide. 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 minamii is a parasitoid of Kiefferia pericarpiicola (Bremi) ( Diptera : Cecidomyiidae ) on Angelica sachalinensis Maxim. var. sachalinensis (Apiaceae) , A. edulis Miyabe ex Y. Yabe (gall photo: fig. 27c), and Spuriopimpinella calycina (Maxim.) Kitag. (Apiaceae) . Remarks. Females of T. minamii are similar to T. sasae Matsuo because 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. minamii can be distinguished from T. sasae by 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 ).
