Description.

Female (holotype, Figs 19-22 ). Body length 1.9 mm. Head with metallic tinge, eye red; ocelli dark red; antenna with scape, pedicel and flagellum yellow; mandible dark brown. Mesosoma with strong metallic tinge. Legs yellow except metacoxa mostly with metallic luster, as on mesosoma, and apical tarsomeres dark. Tergum I yellow except for metallic tinge in a triangular anteromedial area; terga II-IV entirely yellow; tergum V mostly yellow except medially with a faint pale brown round with faint metallic tinge; tergum VI mostly yellow, with brown stripe from anterior to posterior margins with green metallic tinge, with anterior margin brown; tergum VII with anterior triangular-shaped area dark brown with green metallic tinge, with yellow part laterally which is larger than the metallic area (Fig. 20 ). Ovipositor dark brown with metallic tinge; hypopygium laterally with a yellow oval area surrounded by brown to black part; upper outer plate of ovipositor with two dark brown stripe areas with metallic reflections on either side of ovipositor, and lower outer plate of ovipositor with yellow stripe-like part between dark brown stripe and ovipositor, which is linked with tergum VII.

Head (Fig. 21 ) 1.2 × as wide as high, 1.6 × as wide as midlobe of mesoscutum.

Ocellar triangle surrounded by shallow grooves. POL 5.0 × OOL. Malar space about 0.4 × eye height. Torulus at lower margin of eye. Malar sulcus strongly curved.

Antenna (Fig. 21 ) with scape 4.6 × as long as wide, not reaching anterior ocellus; pedicel 2.0 ×, F1 1.7 ×, F2 1.5 ×, F3 1.1 ×, and clava 2.1 × as long as wide; C3 short with rounded apex, without a terminal spine.

Mesosoma 1.8 × as long as wide, convex. Pronotum in dorsal view medially very short. Mesoscutum with midlobe about 1.1 × as long as wide, with median line very weak, and with a single row of 3 or 4 adnotaular setae. Scutellum 1.15 × as long as wide, with anterior pair of setae in its posterior half, submedian and sublateral grooves strong and parallel to each other. Propodeum medially as long as dorsellum, with a median carina but without paraspiracular carinae; callus with 4 or 5 setae; with a groove extending from spiracle to posterior margin of propodeum.

Fore wing (Fig. 22 ) hyaline, 1.8 × as long as wide; speculum large, extending from parastigma to stigmal vein. Discal setae short. CC 2.0 × as long as MV; MV thick, 5.0 × as long as wide; MV 2.2 × as long as STV, with 7 marginal setae (about 0.5 × as long as STV); STV rather thick; PSV not thicker than MV, short, stub-like. Hind wing rounded apically, 4.7 × as long as wide.

Legs. Metafemur 3.3 × as long as wide.

Metasoma 1.2 × as long as mesosoma, 2.0 × as long as wide; hypopygium extending to about half length of metasoma; cercal setae subequal in length; ovipositor sheath slightly protruding.

Variation (paratypes, Figs 23-26 ). Body length 1.9-2.0 mm. Metasomal tergum V with pale brown round from nearly invisible to visible (Figs 20 , 23 , 25 ); tergum VI with brown stripe small to large, anterior margin pale brown to brown; tergum VII with anterior triangular-shaped to crescent-shaped area dark brown with green metallic tinge, laterally with yellow part occupying mostly area of tergum VII. Ovipositor brown to dark brown with faint green or orange metallic tinge; hypopygium with oval shaped yellow area middle size to large, which is surrounded by brown to black part with metallic tinge; upper outer plate of ovipositor with dark brown stripes narrow to wide, relatively, lower outer plate of ovipositor with yellow stripe-like part from wide to narrow (Figs 24 , 26 ).

Male. Unknown.

Etymology.

The species name is a noun in apposition; it is derived from the first and second authors’ son’s first name, Yuxuan (Wang Yuxuan).
