Second metasomal tergite usually entirely smooth, only sometimes shortly striate basolaterally. Ovipositor sheath 1.4–1.7 × longer than metasoma, 0.8–1.0 × as long as fore wing. Body dark brown or black almost entirely; hind tibia basally light............ 6

6. Antennae setiform. Penultimate flagellomere of female slender, 2.6–3.2 × longer than wide. Radial vein arising usually less distinctly behind middle of pterostigma, from its apical 0.40–0.45. Second radial abscissa (3-SR) of fore wing longer, 3.0–4.2 (rarely 2.5) × longer than first abscissa, 0.5–0.6 × as long as third abscissa, 1.2–1.5 (rarely 1.15) × longer than first radiomedial vein. Second radiomedial (submarginal) cell 2.0–2.7 × longer than its maximum width. Second metasomal tergite basolaterally with rather long or sometimes short striation. Hind coxa entirely reddish brown or dark reddish brown. Body length 3.5–6.8 mm. Japan.......................................................... S. japonica Belokobylskij et Maeto, 2006

–. Antennae filiform. Penultimate flagellomere of female thick, 2.0–2.2 × longer than wide. Radial vein arising distinctly behind middle of pterostigma, from its apical 0.33–0.4. Second radial abscissa (3-SR) of fore wing relatively shorter, 2.0–2.6 × longer than first abscissa, 0.45–0.50 × as long as third abscissa, 1.0–1.2 × as long as first radiomedial vein. Second radiomedial (submarginal) cell about twice longer than its maximum width. Second tergite usually without basal striation or rarely with short striae.
