Type material. HOLOTYPE (Ƥ, IZCAS). CHINA: Hainan: Wenchang, Touyuan Village, 24.V.2009, coll. Tingyu Hu.

PARATYPES (9Ƥ 8♂, IZCAS). Same data as holotype.

Etymology. The specific name is from the name of the type locality, Wenchang of Hainan Province.

Description. FEMALE. Length = 2.8 mm. Head except vertex green with bright metallic gloss, vertex with purple tint. Mandible brownish yellow; eye pink, ocelli transparent. Antenna with scape yellow, pedicel and anellus brown, all funicular segments and clava dark brown. Mesosoma green with bronze gloss except propodeum with purple gloss. Wings hyaline, veins pale brown. Legs with fore and mid coxae yellow; hind coxa concolorous with mesosoma; all femora, tibiae and claws yellowish brown. Metasoma black-brown except petiole and ovipositor brownish yellow.

Head in dorsal view 2× as wide as long, vertex smooth except posterior margin with transverse reticulation; temple 0.6× eye length; POL 1.9× OOL; occipital carina fine, reaching vertex; posterior ocelli near occipital carina, about 0.5× length of their own diameter. Head in anterior view 1.3× as high as wide ( Fig. 7 ); upper face with engraved reticulation; lower face with dense, raised reticulation; scrobe distinct. Ventral margin of clypeus slightly protruded; tentorial pits distinct and vertical suture between pit and the margin of mouth distinct but shallow; eye height 3.1× eye width and about 4.3× malar space; inner margins of eyes slightly convergent to clypeus ( Fig. 7 ); mandible tridentate. Antenna ( Fig. 7 ) clavate, inserted at center of face; scape 0.7× as long as eye height, at most reaching ventral margin of anterior ocellus; combined length of pedicel and flagellum equal to head width; anellus subquadrate; funicle with fu1 quadrate, 0.5× as long as fu2, fu2 1.1–1.2× as long as it greatest width, fu3 and fu4 quadrate, fu5–fu7 subquadrate, and each funicular segments bearing one row of longitudinal sensilla; clava slightly longer than fu6 and fu7 combined.

Mesosoma convex in lateral view ( Fig. 6 ), slightly narrower than head. Pronotum with raised reticulation, pronotal collar rectangular in dorsal view, distinctly narrower than mesoscutum, and with anterior edge sharply margined ( Fig. 8 ). Mesoscutum with raised reticulation; notauli distinct and complete. Scutellum with engraved reticulation except for frenum, almost as wide as long and distinctly convex in anterior 1/3 ( Fig. 6 ); frenal line with a row of coarse punctures. Propodeum smooth, median carina distinct, with several longitudinal carinulae basally. Fore wing ( Fig. 9 ) 2.4× as long as wide; costal cell bare; basal area, disc and speculum bare; subcubital setal line with sparse setae from speculum to apical margin of wing; marginal vein 8.3× as long as postmarginal vein; postmarginal vein and stigmal vein very short, postmarginal vein 1.5× as long as stigmal vein. Hind coxa reticulate, dorsal surface with a longitudinal carina; hind femur without ventral teeth, 4.5× as long as wide; hind tibia with two short spurs; basitarsus 0.3× as long as hind tibia.

Metasoma as long as mesosoma. Petiole 0.8× as long as hind coxa, laterally carinate and with distinct median carina. Gaster arched ( Figs 6, 10 ) in lateral view; dorsally smooth, 1.5× as long as wide; Gt1 with hind margin protruded into U shape; Gt2 with hind margin strongly incised medially ( Fig. 10 ); Gt3 longest, Gt3 and Gt4 combined about 0.7× length of gaster; ovipositor sheath distinctly protruded, 0.8× as long as gaster.

MALE. Length = 2.3 mm. Head and thorax bluish green, gaster dark brown; antenna black-brown except scape yellow; eye pale pink. Eye height 7.8× malar space; inner margins of eyes strongly convergent to clypeus ( Fig. 11 ). Head in dorsal view 2.2× as wide as long, temples about half length of eye. Antenna with scape at most reaching anterior ocellus, as long as head width. Pronotum narrower than mesoscutum. Scutellum oval, strongly convex and smooth, with frenal line distinct. Propodeum smooth, median carina complete. Petiole longer than scutellum, 1.8× as long as hind coxa ( Fig. 12 ). Gaster1.2× as long as wide, as broad as mesoscutum, shorter than mesosoma; Gt1 with hind margin protruded into U shape medially; Gt2–Gt5 with hind margins truncate; Gt3–Gt5 of equal length.

Distribution. China (Hainan).

Biology. All the specimens were swept around a big flowering tree (probably Ericaceae ) in Touyuan Village of Wenchang, Hainan Province.

Remarks. Females of O. wenchangica are similar to those of O. josephinae in having hyaline fore wings, but they differ by the features given in the key. Males of the new species are similar to O. philippiae , but are differentiated by those features given in the key.
