(Fig. 15)
Description. Female. Body length 2.7 mm; fore wing length 2.15 mm.
Head. Antennae slender, filiform, 19-segmented. Scape 1.5 times as long as maximum width. First flagellar segment 4.5 times as long as its apical width, as long as second segment. Penultimate segment 4.0 times longer than wide, 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 2.8 times as long as temple (dorsal view). Ocelli arranged in almost equilateral triangle. POL: OD: OOL = 2: 2: 5. Vertex and frons smooth. Vertex with sparse, short setae. Face finely striate laterally, smooth medially, its width equal to height of eye, 1.1 times height of face and clypeus combined. Eye glabrous, 1.2 times as high as broad. Malar space 0.3 times height of eye, 0.8 times basal width of mandible. Malar suture absent. Occipital carina complete dorsally, fused with hypostomal carina ventrally.
Mesosoma. Length 2.4 times its height. Mesoscutum densely granulate with fine transverse striate, highly and perpendicularly elevated above pronotum, entirely with dense setae. Notauli complete, deep anteriorly and shallow posteriorly, sparsely and distinctly crenulate. Scutellum entirly granulate. Prescutellar depression deep, rather long, rugulose, with single median carina, 0.5 times as long as scutellum. Mesopleuron rather widely granulate-rugulose, coriaceous around precoxal sulcus. Subalar depression shallow, 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 finely granulate and distinctly rugulose-reticulate along carinae; remaining part of propodeum coarsely rugose-areolate.
Wings. Fore wing 3.6 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 = 11: 5: 31. First discal cell 1.6 times as long as its maximum width. 1-SR+M distinctly curved. m-cu postfurcal. Hind wing: M+CU: 1-M = 9: 10. m-cu weakly curved towards base of wing, antefurcal, pigmented.
Legs. Hind coxa finely striate dorsally. Hind femur smooth, 3.2 times as long as wide. Hind tibia dorsally with long, sparse and semi-erect setae; length of these setae 0.5–1.2 times maximum width of hind tibia. 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 0.8 times as long as basitarsus, 1.3 times as long as fifth segment (except pretarsus).
Metasoma. about 1.1 times as long as mesosoma and head combined. First tergite with 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 distinct, curved laterally and weakly curved medially. 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 half distinctly striate. Fourth tergite in basal half and fifth tergite in basal 0.3 striate. Remaining tergites smooth. Ovipositor sheath 0.5 times as long as metasoma and 0.3 times as long as fore wing.
Colour. Head brownish yellow. Mesosoma brownish yellow to black, pronotum, propleuron, mesonotum, mesopleuron and scutellum yellow, remaining parts of mesosoma dark. First tergite black; second-fourth tergites brown yellow, remaining tergites yellow. Antennae brownish yellow to black, two basal segments brownish yellow. Palpi pale yellow. Legs yellow. Ovipositor sheath dark brown. Wings faintly infuscate. Pterostigma brown, pale basally and apically.
Male. Unknown.
Material examined. Holotype: Ƥ, China, Hainan Prov., Diaoluoshan, 28–31.V.2007, Liu Jingxian, No. 200702932 (ZJUH).
Diagnosis. This new species is similar to H. hemitestaceus Belokobylskij, but differs in having the mesosoma weakly depressed (2.4 times as long as height), apical segments of antenna dark, scutellum entirely granulate, and mesopleuron rather widely granulate-rugulose, coriaceous around precoxal sulcus.
Etymology. From Latin “semi” meaning “half”, and “depressus” meaning “depressed”.
Distribution. China (Hainan).
