Figs. 5–6

Materia examined. Holotype: female, Yunnan, Menghai , 18.VII.1983, Luo Hengwen, No840477 . Paratype: 1 male, Yunnan, Menghai, 22.VII.1983, Luo Hengwen, No 835410 .

Description. Female holotype. Body length 12.4 mm, fore wing length 7.1 mm.

Head. Antenna with 43 flagellomeres; first flagellomere 1.3× longer than second flagellomere. Face strongly rugose. Clypeus strongly rugose, slightly convex, apical margin curved. Malar space granulose, 0.4× basal width of mandible. Mandible with lamella. Frons rugose, without a median carina. Vertex granulose. Interocellar distance 2.0× ocello-ocular distance and 2.4× distance between median and lateral ocelli. Temple granulose, mat, 0.3× as long as eyes in dorsal view. Occipital carina evenly arched.

Mesosoma. Pronotum granulose-rugulose dorsally, transversely striate laterally. Mesoscutum punctate on median lobe, rugose-punctate on notaulic area. Scutellum rugose-reticulate. Metanotum rugose. Mesopleuron rugose-reticulate dorsally, slightly striate below tegula, punctate ventrally. Metapleuron rugulose dorsally, rugose ventrally, juxtacoxal carina strong. Propodeum strongly rugose-reticulate, propodeal spiracle oval.

Wing. Fore wing without areolet. Marginal cell short, RS vein 1.3× longer than 2r&RS vein. Vein 1cu-a slightly distad of M&RS. External angles of second discal cell acute (80°). Hind wing with 1-cu vertical, ca 2.5× longer than cu-a.

Legs. Hind femur 6.0× longer than wide. Inner spur of hind tibia 0.7× as long as first tarsomere of hind tarsus. Tarsal claws pectinate, with 5 teeth, apically strongly upcurved.

Metasoma. Slender. Basal 0.3 of first metasomal segment round in cross-section. Second tergite 0.7× as long as first tergite; thyridium oval, its distance from basal margin of tergite ca 1.2× its length; metasoma strongly compressed. Ovipositor 1.1× longer than hind femur, straight, curved downward apically.

Colour. Mandible, palpi and tegula yellowish brown; scape and pedicel blackish brown; fore leg yellow except femur ventrally yellowish brown; mid leg yellow except trochanter, trochantellus, and femur ventrally blackish brown; hind coxa, trochanter, trochantellus and femur blackish brown, hind tibia except apically yellowish brown, infuscated apically, tarsus brown; metasoma entirely yellowish brown except second tergite dorsally black.

Male. Essentially same to female.

Male genitalia. Parameres narrow, rod-like.

Host. Cania bilineata (Walker, 1855) .

Distribution. China (Yunnan).

Comparative diagnosis. This species runs in the key by He et al. (1996) to S. exareoletus, He, 1980 , but the new species differs from latter by having mesopleuron punctate ventrally (rugose-reticulate in S. exareoletus ), hind tarsal claw strongly curved apically (weakly curved in S. exareoletus ), scape and pedicel blackish brown (yellowish brown in S. exareoletus ), and hind femur blackish brown (yellowish brown in S. exareoletus ).

Etymology. Name derived from the name of type locality of species.
