Holotype. 3, China, Hainan Prov., Wuzhishan, 16–20.V.2007, Liu Jingxian, No. 200703304 ( ZJUH). Paratypes. 233, same data as holotype, Nos. 200703263, 200703387 ( ZJUH).

Description. Male. Body length 6.2 mm; fore wing length 4.8 mm.

Head. Antennae slender, filiform, 51-segmented. Scape 1.3 times as long as maximum width. First flagellar segment 3.7 times as long as its apical width, 1.4 times as long as second segment. Penultimate segment 2.7 times as long as wide, 0.4 times as long as first flagellar segment, 0.9 times as long as apical segment. Head width 1.2 times its median length. Vertex smooth. Frons weakly concave, widely medially rugose-striate; temple smooth. Temple behind eyes roundly narrowed in dorsal view. Transverse diameter of eye as long as temple in dorsal view. Ocelli medium-sized, in triangle with base equal to its sides. POL: OD: OOL=4: 3: 9. Eye glabrous, 1.3 times as high as broad. Malar space 0.4 times height of eye, 0.9 times basal width of mandible. Face densely striate-rugose, narrowly almost smooth medially; Face width 1.1 times height of eye, 1.1 times height of face and clypeus combined. Malar suture absent. Hypoclypeal depression round, 0.4 times width of face.

Mesosoma weakly depressed, its dorsal side almost flat. Length 2.8 times its height. Sides of pronotum entirely rugose. Posterior third of pronotum with weakly convex lobe dorsally and with distinct pronotal keel, which is situated close to mesoscutum, but not fused with it medially. Median lobe of mesoscutum weakly roundly convex, with a shallow and wide median longitudinal furrow. Notauli deep anteriorly, shallow posteriorly, crenulate. Prescutellar depression rather deep, with a distinct median carina. Scutellum punctate. Metanotum without median tooth. Mesopleuron punctate anteriorly and posteriorly, but its small median part smooth. Subalar sulcus shallow, rather wide, rugose. Precoxal sulcus distinct, shallow, rather wide and crenulate, connected with prepectal carina anteriorly, running ventrally along entire length of mesopleuron, weakly curved in posterior half. Propodeum coarsely rugose-reticulate, with an almost complete median carina. Propodeum without lateral tubercles. Mesoscutum entirely shortly and densely setose. Mesopleuron almost entirely densely setose.

Wings. Fore wing 4.6 times as long as maximum width. Pterostigma 4.6 times as long as wide. Vein r arising before middle of pterostigma. 1-R1 1.3 times as long as pterostigma. 3-SR: r: SR1: 2-SR= 42: 10: 74: 27. Second submarginal cell long, 3.8 times as long as maximum width, 0.9 times as long as first subdiscal cell. 1-SR+M vein weakly sinuate. m-cu vein slightly postfurcal. Hind wing with 6 hamuli. M+CU vein 0.2 times as long as 1-M vein. Vein m-cu weakly curved, short, pigmented, antefurcal.

Legs. Fore tarsus short, 1.5 times as long as fore tibia. Fore tibia with very small spines arranged in narrow band. Hind coxa coarsely transversely rugose-striate dorsally. Baso-ventrally hind coxa angled and with a small tubercle. Hind femur 3.1 times as long as its maximum width. Hind tarsus slender, 0.9 times as long as hind tibia. Hind basitarsus 0.6 times as long as second-fifth segments combined; second tarsal segment 0.5 times as long as basitarsus, 0.9 times as long as fifth segment (without pretarsus).

Metasoma 1.2 times as long as mesosoma and head combined. First tergite with distinct dorsope, with small spiracular tubercles in basal 0.2, almost linearly widened from base to apex. First tergite densely areolate. Maximum width of first tergite 1.5 times its minimum width; length 2.0 times its maximum width, about 1.4 times length of propodeum. Second tergite with distinct anterolateral furrows, its basal 0.8 with a triangular area bordered by deep grooves, and grooves divergent in suture between second and third tergites; second tergite almost as long as its basal width, and as long as third tergite. Triangular area petiolate posteriorly, its length 1.3 times basal width. Suture between second and third tergites deep, narrow, weakly curved towards base of tergite. Third-fifth tergites in basal half with semi-oval areas. Third and fourth tergites with roundly divergent medio-lateral furrows in posterior half. Second-fifth tergites with dense and fine, almost regular reticulation (except smooth posterior half of third and fourth tergites, and smooth posterior 0.7 of fifth tergite). Sixth tergite smooth.

Colour. Head red. Mesosoma almost black, mesopleuron with large reddish brown spots. Metasoma black. Antenna black, two basal segment reddish brown. Palpi pale yellow. Fore and mid coxae whitish yellow; hind coxa almost black; all trochanters whitish yellow; all femora black; all tibiae almost brownish yellow, mid and hind tibiae pale basally; all tarsi almost brownish yellow. Wings faintly infuscate. Pterostigma dark brown.

Female. Unknown.

Variation. Body length 4.9–6.3 mm; fore wing length 3.5 mm. Scape 1.1 times as long as its maximum width. First flagellar segment 4.0 times as long as its apical width, 1.5 times as long as second segment. Transverse diameter of eye 1.2 times as long as temple in dorsal view.

Diagnosis. This new species is similar to H. sonata Belokobylskij , but differs in occipital carina dorsally complete and distinctly curved medially; hind wing with 6 hamuli; fore and mid coxae whitish yellow, and hind coxa almost black.

Distribution. China (Hainan).

Etymology. From the Wuzhi Mountain, type locality of the species.
