Eyes slightly protruding, glabrous, in dorsal view its length 1.3 × length of temple ( Fig. 2H View FIGURE 2 ). Clypeus distinctly separated from face, evenly convex, sparsely punctulate, with obliquely stripe in apical half ( Fig. 2F View FIGURE 2 ). Occipital carina incomplete, medially smooth and absent ( Fig. 2D View FIGURE 2 ). Fore wing ( Fig. 2B View FIGURE 2 ): length of pterostigma 3.3 × its width; r:3-SR =19:22, r-m present, unpigmented; vein 2-SR+M present; m-cu complete 1-CU1:2-CU1=5:69. Hind femur 3.0 × longer than wide ( Fig. 2L View FIGURE 2 ). Length of T1 and T2 1.5 × their apical width ( Fig. 2I View FIGURE 2 ). Metasomal carapace in lateral view evenly rounded apically ( Fig. 2J View FIGURE 2 ).

Colour. Scapus brown, antenna darkened towards apex (pedicellus brownish-yellow, antenna darkened towards scapus); legs white-yellowish-brown; fore and middle femur, tibia (except its base), second to fourth of fore and middle tarsi light brownish-yellow, first tarsus and basitarsus light brown, the remaining whitish yellow; apical half of hind femur, tibia, first tarsi, and basitarsus blackish-brown. Wing membrane dark brown with pale band below base of pterostigma; pterostigma brown, veins of fore wing brown, veins of hind wing yellowish-brown.
Distribution. China (Yunnan).
Biology. Unknown.
Etymology. The species is named after the location (Yunnan province, southern China) where the type species was collected.
Discussion. We have collected two specimens provisionally included in S. yunnanensis , of which the holotype female differs from the male specimen. The male specimen is larger than the female; female antenna is more robust (which is what is expected) but darker coloured; male wing ( Fig. 2B View FIGURE 2 ) darker membrane and veins almost complete (female veins incomplete); precoxal sulcus of male ( Fig. 2E View FIGURE 2 ) distinct and concave, densely punctate (female: indistinct, not concave but densely punctate); propodeum of female densely crenulate (male: punctate antero-medially ( Fig. 2G View FIGURE 2 )); occipital carina of female nearly complete, medially weakly developed (male: area medially smooth and carina absent). Because of these differences, we have not designated the male as a paratype.
