First flagellar segment 5.5 times as long as its apical width, 0.9 times as long as second segment. Penultimate segment 4.0 times longer than wide, 0.8 times as long as first flagellar segment, as long as apical segment. Head behind eyes (dorsal view) regularly and roundly narrowed. Width of head 1.4 times its median length. Eye 3.4 times as long as temple (dorsal view). Ocelli arranged in almost equilateral triangle. POL: OD: OOL = 2: 2: 7. Head entirely smooth. Vertex with sparse, short setae. Face smooth, its width equal to height of eye, 1.4 times height of face and clypeus combined. Eye glabrous, 1.1 times as high as broad. Malar space 0.3 times height of eye, 0.6 times basal width of mandible. Malar suture absent. Occipital carina complete dorsally, fused with hypostomal carina ventrally. FIGURE 3.

A , habitus, lateral aspect; B , head, dorsal aspect; C , head, frontal aspect; D , wing; E , antennae; F , mesosoma, lateral aspect; G, metasoma, dorsal aspect; H, mesoscutum, dorsal aspect; I , propodeum, dorsal aspect. Scale bar 0.5 mm. Mesosoma . Length 2.0 times its height. Mesoscutum almost smooth, highly and perpendicularly elevated above pronotum, with densely setae. Notauli shallow, wide, sparsely and distinctly crenulate. Scutellum smooth. Prescutellar depression deep, rather long, smooth, with three distinct carinae, 0.6 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 distinctly delineated areola, basal carina short; basolateral areas almost smooth and distinctly rugulose-reticulate along carinae; remaining part of propodeum coarsely rugose-areolate. Wings . Fore wing 3.1 times as long as maximum width. Vein r arising almost from middle of pterostigma. 3-SR forming very obtuse angle with r. 3-SR: r: SR1 = 14: 6: 38. First discal cell 2.0 times as long as maximum width. 1- SR+M distinctly curved. m-cu postfurcal. Hind wing: M+CU: 1-M = 12: 15. m-cu almost straight, oblique towards base of wing, antefurcal, pigmented. Legs . Hind coxa distinct striate dorsally. Hind femur smooth, 3.7 times as long as wide. Hind tibia with rather long and sparse setae dorsally; length of these setae 0.5–1.4 times maximum width of hind tibia. Hind tarsus as long as hind tibia. Hind basitarsus 0.4 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 0.9 times 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 2.5 times its minimum width, length 1.1 times its maximum width. Suture between second and third tergites deep, almost straight. Second tergite entirely and densely striate, its median length 0.6 times basal width, 0.9 times length of third tergite. Third tergite in basal 0.3 with fine, rather narrow, transverse furrow. Third-fifth tergites in basal 0.4-0.5 distinctly and densely striate. Remaining tergites smooth. Ovipositor sheath 0.55 times as long as metasoma and 0.3 times as long as fore wing. Colour . Head and mesosoma brownish yellow. Metasoma almost dark brown, seventh and eighth tergites brownish yellow. Antennae brownish yellow to black, two basal segments brownish yellow, six apical segments white. Palpi pale yellow. Legs brownish yellow, all coxae and trochanters pale yellow. Ovipositor sheath dark brown, paler basally. Wings faintly infuscate. Pterostigma dark brown. Variation. Body length 2.5 mm ; fore wing length 2.2 mm . Width of head 1.3 times its median length. Mesosoma 1.9 times as long as its height. Fore wing 3.0 times as long as maximum width. Male. Unknown. Material examined. Holotype : Ƥ, China , Hainan Prov., Diaoluoshan, 1–2.VI.2007 , Liu Jingxian, No. 200704010 ( ZJUH ). Paratypes . China , Hainan Prov.: 1Ƥ, Jianfengling, 6.VI.2007 , Liu Jingxian, No. 200703802 ( ZJUH ); 1Ƥ, Jianfengling, 28.V–3.VI.2007 , Weng Liqiong, No. 200804243 ( ZJUH ). Diagnosis . This new species is similar to H. alboapicalis Belokobylskij , but differs in having the head, mesoscutum and hind femur smooth, temple and ovipositor sheath short, and first tergite apically wider. H. chui sp. nov. is also similar to H. setosiscutum sp. nov. and H. setosus sp. nov. ; the differences between these species are shown in the key. Etymology . The species is named in honour of Prof. Chu Joo-tso, the well-known Chinese hymenopterist. Distribution . China (Hainan).
