(Fig. 8)
Description. Female. Body length 3.8 mm; fore wing length 2.8 mm.
Head. Antennae slender, filiform, more than 14-segmented (apical segments missing). Scape 1.3 times as long as maximum width. First flagellar segment 4.3 times as long as its apical width, as long as second segment. Head behind eyes (dorsal view) distinctly and roundly narrowed. Width of head 1.5 times its median length. Eye 3.2 times as long as temple (dorsal view). Ocelli arranged in triangle with base 1.7 times its sides. POL: OD: OOL = 3: 3: 7. Vertex and frons smooth. Vertex with sparse, short setae. Face finely rugose with punctation, its width 1.1 times height of eye, 1.3 times height of face and clypeus combined. Eye glabrous, 1.2 times as high as broad. Malar space 0.4 times height of eye, equal to basal width of mandible. Malar suture absent. Occipital carina complete dorsally, fused with hypostomal carina ventrally.
Mesosoma. Length 1.9 times its height. Mesoscutum striate-rugose, highly and perpendicularly elevated above pronotum, with sparse setae arranged along notauli. Notauli shallow, sparsely and distinctly crenulate. Scutellum smooth. Prescutellar depression deep, rather long, smooth, with single distinct median carina, 0.5 times as long as scutellum. Subalar depression rather wide, coarsely rugose-striate. Precoxal sulcus deep, smooth, running along anterior 0.7 of lower part of mesopleuron. Propodeum with distinctly delineated by carinae and long basolateral areas, with delineated areola, basal carina short; basolateral areas mostly smooth, only rugose posteriorly; remaining part of propodeum coarsely rugose-areolate.
Wings. Fore wing 3.2 times as long as maximum width. Vein r arising before middle of pterostigma. 3-SR forming very obtuse angle with r. 3-SR: r: SR1 = 15: 7: 45. First discal cell 1.9 times as long as maximum width. 1- SR+M distinctly curved. m-cu postfurcal. Hind wing: M+CU: 1-M = 13: 16. m-cu almost straight, oblique towards base of wing, antefurcal, pigmented.
Legs. Hind coxa distinctly striate dorsally. Hind femur smooth, 3.5 times as long as wide. Hind tibia with long, sparse setae dorsally; length of these setae 0.7–1.0 times maximum width of hind tibia. Hind tarsus 0.9 times as long as hind tibia. Hind basitarsus 0.5 times as long as second-fifth segments combined; second tarsal segment 0.8 times as long as basitarsus, 1.4 times as long as fifth segment (except pretarsus).
Metasoma. Almost 1.1 times as long as mesosoma and head combined. First tergite with more or less distinct, weakly and curvedly convergent posteriorly dorsal carinae, entirely densely and coarsely striate, with fine reticulation between them; apical width of tergite 2.0 times its minimum width, length 0.7 times its maximum width. Suture between second and third tergites deep and slightly curved laterally. Second tergite entirely densely and coarsely striate, median length of tergite 0.4 times its basal width, 0.7 times length of third tergite. Third tergite in basal 0.3 with a distinct, wide, transverse furrow. Third tergite in subbasal depression widely, fourth and fifth tergites in basal half striate. Remaining tergites smooth. Ovipositor sheath 0.6 times as long as metasoma and 0.4 times as long as fore wing.
Colour. Body brownish yellow. Metasoma almost brownish yellow, first tergite entirely, second tergite basally, third and fourth tergites apically dark. Antennae brownish yellow to black, two basal segments brownish yellow. Palpi pale yellow. Legs brownish yellow, all coxae and trochanters pale yellow. Ovipositor sheath dark brown. Wings faintly infuscate. Pterostigma dark brown, pale basally and apically.
Variation. Body length 3.6 mm; fore wing length 2.7 mm. First discal cell 1.85 times as long as maximum width.
Male. Unknown.
Material examined. Holotype: Ƥ, China, Hainan Prov., Jianfengling, Tianchi, 22–23.X.2007, Liu Jingxian, No. 200710431 (ZJUH). Paratypes. China, Hainan Prov.: 1Ƥ, same locality and date as holotype, Liu Jingxian, No. 200710798 (ZISP); 1Ƥ, Yinggeling, 24–26.V.2007, Liu Jingxian, No. 200704178 (ZJUH). Yunan Prov.: 1Ƥ, Ruili Mengxiu, 2–6.V.1981, He Junhua, No. 812980 (ZJUH).
Diagnosis. This new species is similar to H. tulyensis Belokobylskij, but differs in having the vertex and frons smooth, mesoscutum with sparse setae arranged along notauli, pterostigma dark brown, but pale basally and apically. H. liui sp. nov. is also similar to H. cephi (Rohwer), but differs in having the temple short, vertex mainly smooth, mesoscutum with distinct striae along notauli.
Etymology. This species is named in honour of Dr Liu Jingxian, the collector of the holotype.
Distribution. China (Hainan).
