Scale bar 0.5 mm. Mesosoma . Length 1.7 times its height. Mesoscutum finely coriaceous, highly and perpendicularly elevated above pronotum, with very sparse setae arranged along notauli. Notauli deep, sparsely and distinctly crenulate. Scutellum smooth. Prescutellar depression deep, rather long, smooth, with five distinct carinae, 0.5 times as long as scutellum. Subalar depression rather wide, coarsely rugose-striate. Precoxal sulcus deep, crenulate, running along anterior 0.7 of lower part of mesopleuron. Propodeum with distinctly delineated by carinae and long basolateral areas, with distinctly delineated areola, basal carina very short; basolateral areas almost smooth and distinctly rugulose-reticulate along carinae; remaining part of propodeum coarsely rugose-areolate. Wings . Fore wing 3.4 times as long as maximum width. Vein r arising distinctly before middle of pterostigma. 3-SR forming very obtuse angle with r. 3-SR: r: SR1 = 13: 10: 45. First discal cell 1.8 times as long as maximum width. 1-SR+M distinctly curved. m-cu postfurcal. Hind wing: M+CU: 1-M = 15: 18. m-cu weakly curved towards base of wing, antefurcal, pigmented. Legs . Hind coxa finely striate dorsally. Hind femur smooth, 3.6 times as long as wide. Hind tibia with rather short and dense setae dorsally; length of these setae 0.2–0.3 times maximum width of hind tibia. Hind tarsus 0.8 times as long as hind tibia. Hind basitarsus 0.5 times as long as second-fifth segments combined; second tarsal segment 0.7 times as long as basitarsus, 1.4 times as long as fifth segment (except pretarsus). Metasoma . Almost as long as mesosoma and head combined. First tergite with more or less distinct, weakly and curvedly convergent posteriorly dorsal carinae, densely and coarsely striate; apical width of tergite 2.0 times its minimum width, length almost equal to its maximum width. Suture between second and third tergites deep and distinctly sinuate. Second tergite entirely and densely striate, median length of tergite 0.4 times its basal width, 0.8 times length of third tergite. Third tergite in subbasal 0.4 distinctly striate. Fourth tergite in basal 0.2 shortly striate. Fifth tergite shortly striate basally. Remaining tergites smooth. Ovipositor sheath 0.9 times as long as metasoma and 0.6 times as long as fore wing. Colour . Head yellow. Mesosoma yellow to black, pronotum, propleuron, mesonotum, mesopleuron and scutellum yellow, remaining parts of mesosoma dark. Metasoma dark brown, first-fourth tergites dark brown, remaining tergites brownish yellow. Antennae brownish yellow to black, two basal segments brownish yellow. Palpi pale yellow. Legs yellow. Ovipositor sheath dark brown. Wings faintly infuscate. Pterostigma light brown. Variation. Body length 3.4–3.6 mm ; fore wing length 2.4–2.6 mm . Antennae 30-segmented. First flagellar segment 4.6–4.8 times as long as its apical width. Eye 2.6 times as long as temple (dorsal view). Face smooth, its width equal to height of eye, 1.2 times height of face and clypeus combined. Mesosoma 1.8–1.9 times as long as its height. Mesoscutum almost smooth. Fore wing 3.1–3.6 times as long as maximum width. First discal cell 1.9 times as long as maximum width. Hind femur 3.2–3.4 times as long as wide. Apical width of first tergite 1.8–1.9 times its minimum width. Male. Unknown. Material examined. Holotype : Ƥ, China , Hainan Prov., Jianfengling, 7.VI.2007 , Liu Jingxian, No. 200702536 ( ZJUH ).

Diagnosis . This new species is similar to H. pumilio Belokobylskij et Maetô , but differs in having the occipital carina fused with hypostomal carina ventrally, mesoscutum finely coriaceous, notauli deep, hind femur narrow, fifth tergite shortly striate basally, and ovipositor sheath long. Etymology . From Latin “curvus” meaning “curve”, and “sulcus” meaning “suture”. Distribution . China (Zhejiang, Hainan).
