(Fig. 16)
Description. Female. Body length 3.0 mm; fore wing length 2.6 mm.
Head. Antennae slender, filiform, more than 15-segmented (apical segments missing). Scape 1.25 times as long as maximum width. First flagellar segment 5.0 times as long as its apical width, as long as second segment. Head behind eyes (dorsal view) regularly and roundly narrowed. Width of head 1.4 times its median length. Eye 2.2 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 almost smooth, its width equal to height of eye, 1.1 times height of face and clypeus combined. Eye glabrous, 1.3 times as high as broad. Malar space 0.4 times height of eye, equal to basal width of mandible. Malar suture absent. Occipital carina complete dorsally, fused with hypostomal carina ventrally.
Mesosoma. Length 2.2 times its height. Mesoscutum almost smooth, with sparse punctation, highly and almost perpendicularly elevated above pronotum, entirely covered by dense setae. Notauli complete, deep anteriorly and shallow posteriorly, sparsely and distinctly crenulate. Scutellum smooth. Prescutellar depression deep, rather long, smooth, with three carinae, 0.4 times as long as scutellum. Mesopleuron smooth. 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 smooth and distinctly rugulose-reticulate along carinae; remaining part of propodeum coarsely rugose-areolate.
Wings. Fore wing 3.5 times as long as maximum width. Vein r arising before middle of pterostigma. 3-SR forming very obtuse angle with r. 3-SR: r: SR1 = 15: 5: 39. First discal cell 1.6 times as long as maximum width. 1- SR+M distinctly curved. m-cu postfurcal. Hind wing: M+CU: 1-M = 11: 13. m-cu weakly curved towards base of wing, antefurcal, pigmented.
Legs. Hind coxa smooth. Hind femur smooth, 3.4 times as long as wide. Hind tarsus 0.9 times as long as hind tibia. Hind tibia with long and sparse setae dorsally; length of these setae 1.0–1.2 times maximum width of hind tibia. Hind basitarsus 0.4 times as long as second-fifth segments combined; second tarsal segment 0.8 times as long as basitarsus, 1.2 times as long as fifth segment (except pretarsus).
Metasoma. About 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 1.2 times its maximum width. Suture between second and third tergites distinct, weakly sinuate. Second tergite entirely and densely striate, median length of tergite 0.55 times its basal width, 0.8 times length of third tergite. Third tergite in basal 0.3 with transverse and narrowly striate furrow. Fourth tergite with short striation basally. Remaining parts of tergites smooth. Ovipositor sheath 0.7 times as long as metasoma and 0.4 times as long as fore wing.
Colour. Head brownish yellow. Mesosoma mostly brown, lower part of mesopleuron dark brownish yellow. Metasoma mostly brown, its apex brownish yellow. Antennae brownish yellow to black, two basal segments brownish yellow. Palpi pale yellow. Legs yellow, all coxae and trochanters pale yellow. Ovipositor sheath dark brown. Wings faintly infuscate. Pterostigma brown, pale basally and apically.
Variation. Body length 2.9 mm; fore wing length 2.4 mm. Scape 1.3 times as long as maximum width. Hind femur 3.3 times as long as wide. Apical width of tergite 1.9 times its minimum width.
Male. Unknown.
Material examined. Holotype: Ƥ, China, Guizhou Prov., Leigongshan, Fangxiangxiang, 1000 m, 2– 3.VI.2005, Liu Jingxian, No. 200605920 (ZJUH). Paratype. 1Ƥ, China, Guangdong Prov., Shaoguan Nanling, 10– 14.V.2006, Xu Zaifu, No. 200807826 (ZJUH).
Diagnosis. This new species is similar to H. separatus Fischer, but differs in having the mesoscutum entirely and densely setose, temple short, and forth tergite shortly striate basally.
Etymology. From Latin “ setosus ” meaning “setose”, and “scutum” meaning “scutum”. Distribution. China (Guizhou, Guangdong).
