(Fig. 2)
Description. Female. Body length 3.2 mm; fore wing length 2.5 mm.
Head. Antennae slender, filiform, 24-segmented. Scape 1.6 times as long as maximum width. First flagellar segment 4.8 times as long as its apical width, 0.9 times as long as second segment. Penultimate segment 3.5 times longer than wide, 0.75 times as long as first flagellar segment, as long as apical segment. Head behind eyes (dorsal view) regularly and roundly narrowed. Width of head 1.45 times its median length. Eye 2.8 times as long as temple (dorsal view). Ocelli arranged in almost equilateral triangle. POL: OD: OOL = 2: 3: 7. Vertex and frons entirely densely and distinctly transversely striate. Vertex with sparse, short setae. Face coarsely striate, with rugulosity between striae, its width equal to height of eye, 1.2 times height of face and clypeus combined. Malar space 0.3 times height of eye, 0.75 times basal width of mandible. Eye glabrous, 1.2 times as high as broad. Malar suture absent. Occipital carina complete dorsally, fused with hypostomal carina ventrally.
Mesosoma. Length 1.9 times its height. Mesoscutum almost smooth, highly and perpendicularly elevated above pronotum, with sparse setae arranged along notauli. Notauli shallow, wide, sparsely and distinctly crenulate. Scutellum smooth. Prescutellar depression deep, rather long, smooth, with three distinct carinae, 0.3 times as long as scutellum. Subalar depression rather wide, coarsely rugose-striate. Precoxal sulcus deep, smooth, running along anterior half 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, distinctly rugulosereticulate along carinae and in posterior half; remaining part of propodeum coarsely rugose-areolate.
Wings. Fore wing 3.4 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 = 17: 4: 42. First discal cell 2.1 times as long as maximum width. 1- SR+M distinctly curved. m-cu postfurcal. Hind wing: M+CU: 1-M = 12: 15. m-cu weakly curved towards apex of wing, antefurcal, pigmented.
Legs. Hind coxa distinct striate dorsally. Hind femur distinctly and longitudinally striate dorsally, 3.3 times as long as wide. Hind tibia dorsally with short, rather dense and semi-erect setae; length of these setae 0.5–0.7 times maximum width of hind tibia. Hind tibia with rather long and sparse setae dorsally. Hind tarsus 0.9 times as long as hind tibia. Hind basitarsus 0.4 times as long as second-fifth segments combined; second tarsal segment 0.9 times as long as basitarsus, 1.3 times as long as fifth segment (except pretarsus).
Metasoma. Almost 1.15 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 1.3 times its maximum width. Suture between second and third tergites shallow and almost straight. Second tergite entirely and densely striate, median length of tergite 0.6 times its basal width, 0.9 times length of third tergite. Third tergite in basal 0.3 with distinct, rather narrow, transverse furrow. Third-fifth tergites in basal 0.4-0.5 distinctly and densely striate. Remaining tergites smooth. Ovipositor sheath 0.9 times as long as metasoma and 0.6 times as long as fore wing.
Colour. Head brownish yellow, darker dorsally, pale around eyes. Mesosoma almost black, notauli, apical half of median lobe of mesonotum and precoxal sulcus brownish yellow. Metasoma almost black. Antennae brownish yellow to black, two basal segments brownish yellow, five apical segments white. Palpi pale yellow. Legs brownish yellow, pale basally. Ovipositor sheath dark brown, paler basally. Wings faintly infuscate. Pterostigma dark brown.
Variation. Body length 3.4–4.3 mm; fore wing length 2.8–3.3 mm. Antennae 25-segmented. Head width 1.5– 1.6 times its median length. Fore wing 3.2–3.5 times as long as maximum width. First discal cell 1.9–2.0 times as long as maximum width. Hind femur 3.0–3.2 times as long as wide.
Male. Unknown.
Material examined. Holotype: Ƥ, China, Hainan Prov., Jianfengling, 6.VI.2007, Liu Jingxian, No. 200703714 (ZJUH). Paratypes. China, Hainan Prov.: 1Ƥ, same locality as holotype, 4–7.VI.2007, Zeng Jie, No. 200710955 (ZISP); 1Ƥ, Diaoluoshan, 29.V–2.VI.2007, Xiao Bin, No. 200804584 (ZJUH); 1Ƥ, Yinggeling, 28.V–3.VI.2007, Weng Liqiong, No. 200804214 (ZJUH); 1Ƥ, Bawangling, 9–10.VI.2007, Liu Jingxian, No. 200703502 (ZJUH).
Diagnosis. This new species is similar to H. alboapicalis Belokobylskij, but differs in having the mesoscutum smooth, area around eyes pale, second tergite longer, body color more dark and first tergite wider apically.
Etymology. From Greece “bali-” meaning “speckle”, and “cybos” meaning “head”.
Distribution. China (Hainan).
