( Figs 7–13 ) Holotype . Ƥ, China , Hainan Prov., Jianfengling Tianchi, 12–15.VII.2006 , Liu Jingxian, No. 200803581 ( ZJUH ). Description. Female. Body length 6.3 mm ; fore wing length 4.3 mm . Head. Flagellum with a single segment (most segments missing). Scape 1.1 times as long as its maximum width. Head width 1.2 times its median length. Vertex smooth. Frons weakly concave, widely rugose-striate; temple smooth. Temple behind eyes roundly narrowed in dorsal view. Transverse diameter of eye 1.4 times as long as temple in dorsal view. Ocelli medium-sized, in triangle with base equal to its sides. POL: OD: OOL=4.5: 4: 10. Eye glabrous, 1.3 times as high as broad. Malar space 0.4 times height of eye, 0.8 times basal width of mandible. Face densely striate, with rugulosity between striae, smooth medially. Face width 0.9 times height of eye, 1.2 times height of face and clypeus combined. Malar suture absent. Hypoclypeal depression round, its width almost equal to distance from edge of depression to eye, 0.4 times width of face. Occipital carina dorsally complete and distinctly curved medially, not fused below with hypostomal carina. Palpi long, length of maxillary palpus 1.5 times height of head (without mandible). Vertex mostly glabrous, with very sparse erect and rather short setae laterally, temple with very dense semi-erect and rather long setae. Mesosoma. Mesosoma weakly depressed, its dorsal side almost flat. Length 2.7 times its height. Sides of pronotum rugulose-punctate at most part. Posterior half of pronotum with weakly convex lobe dorsally and with distinct pronotal keel, which is situated close to mesoscutum, but not fused with it medially. Mesoscutum densely punctate-granulate entirely. Median lobe of mesoscutum weakly roundly convex, with a shallow and wide median longitudinal furrow. Notauli deep anteriorly, shallow posteriorly, crenulate. Prescutellar depression rather deep, with a distinct median carina, 0.3 times as long as scutellum. Scutellum finely granulate. Metanotum without median tooth. Mesopleuron punctate, but smooth in small median part. Subalar depression shallow, rather wide, rugose. Precoxal sulcus distinct, shallow, rather wide and crenulate, connected with prepectal carina anteriorly, running ventrally along entire length of mesopleuron, weakly curved in posterior half. Propodeum coarsely rugoseareolate, with an almost complete median carina. Propodeum without lateral tubercles. Mesoscutum entirely shortly and densely setose. Mesopleuron almost entirely densely setose. Wings. Fore wing 4.8 times as long as maximum width. Pterostigma 4.7 times as long as wide. Vein r vein arising almost from middle of pterostigma. 1-R1 1.4 times as long as pterostigma. 3-SR: r: SR1: 2-SR= 26: 9: 64: 18. Second submarginal cell long, 2.3 times as long as maximum width, 0.9 times as long as first subdiscal cell. 1- SR+M vein weakly sinuate. m-cu vein slightly antefurcal. Hind wing with 3 hamuli. M+CU vein 0.2 times as long as 1-M vein. Vein m-cu straight, short, pigmented, antefurcal. Legs. Fore tarsus missing. Fore tibia with very small spines arranged in narrow band. Hind coxa almost smooth, very sparsely punctate. Baso-ventrally hind coxa angled and with a small tubercle. Hind femur 3.3 times as long as maximum width. Hind tarsus slender, 1.1 times as long as hind tibia. Hind basitarsus 0.7 times as long as second-fifth segments combined; second tarsal segment 0.6 times as long as basitarsus, 1.6 times as long as fifth segment (without pretarsus). Metasoma 1.4 times as long as mesosoma and head combined. First tergite with distinct dorsope, with small spiracular tubercles in basal quarter, almost linearly widened from base to apex. First tergite densely areolate. Maximum width of first tergite 1.8 times its minimum width; its length 2.8 times maximum width, about 2.2 times length of propodeum. Second tergite with distinct anterolateral furrows, and with triangular area in basal 0.9; tergite 1.1 times as long as its basal width, 1.1 times as long as third tergite. Triangular area petiolate posteriorly, its length 1.5 times basal width. Suture between second and third tergites deep, narrow, weakly curved medially towards base of tergite. Second tergite entirely, third tergite largely (except smooth apical part) and with very dense reticulation; medio-basal half of fourth tergite rugose-reticulate; remaining tergites smooth. Hypopygium obtuse apically. Ovipositor sheath 1.1 times as long as body, 1.6 times as long as fore wing. FIGURES 1–6.

Scale bar 5mm. Colour. Head light reddish brown, frons and vertex around ocelli black. Mesosoma and metasoma black. Palpi pale yellow. Fore and mid coxae whitish yellow; hind coxa almost black; all trochanters whitish yellow; all femora almost black, pale basally; all tibiae and tarsi brownish yellow; mid tarsus, mid and hind tibiae pale basally. Wings faintly infuscate. Pterostigma dark brown Male. Unknown. Diagnosis. This new species is similar to H. rubata Cameron , but differs in hind coxa almost smooth; mediobasal half of fourth tergite rugose-reticulate; mesopleuron almost entirely densely setose; head brownish yellow, mesosoma and metasoma black. Distribution. China (Hainan). Etymology. This species is named in honour of Dr. Liu Jingxian, the collector of the holotype .
