Material examined. Holotype, Female, CHINA: Culai National Forest Park, Tai’an , Shandong province, 21 September 2018, IT. (GSFGPM) . Paratypes: CHINA: 1 female 3 males , same data as holotype except 2 June to 22 September 2018; 1 female 11 males , CHINA: Haoshan, Yiyuan, Zibo , Shandong province, 1 to 23 June 2018, IT. (GSFGPM) .

Description. Female. Body length 6.3–7.0 mm. Fore wing length 4.0– 4.2 mm. Ovipositor sheath length 1.8– 2.0 mm.

Head. Inner margins of eyes almost parallel. Face ( Fig. 2 View FIGURES 2–3 ) approximately 1.4 × as wide as long, with irregular, dense punctures, slightly convex centrally, upper margin with a small median tubercle. Clypeus 1.9 × as wide as long; smooth, evenly convex, basal portion with irregular sparse punctures, apical margin thin, slightly, evenly arched forward and slightly reflexed. Mandible with sparse punctures; upper tooth slightly larger than lower tooth. Malar space with granulose texture. Malar sulcus absent. Malar space approximately 0.9 × as long as basal width of mandible. Gena ( Fig. 3 View FIGURES 2–3 ) almost shiny, lower portion with texture as that of malar space. Upper portion strongly convergent backwardly, with comparatively sparse, fine punctures. Vertex ( Fig. 4 View FIGURES 4–6 ) smooth, shiny, with uneven punctures. Postocellar line approximately 0.8 × as long as ocularocellar line. Frons with granulose texture and sparse punctures, and weak median longitudinal carina. Frons almost flat, with dense punctures. Antenna with 25–26 flagellomeres. Ratio of length from first to fifth flagellomeres: 2.0:1.6:1.4:1.2:1.0. Occipital carina complete.

Mesosoma. Pronotum ( Fig. 5 View FIGURES 4–6 ) shiny, upper-anterior portion smooth; lower portion with fine indistinct punctures, median with irregular large punctures; dorsoposterior with dense fine punctures, distance between punctures 0.2–2.0 × diameter of puncture. Mesoscutum ( Fig. 6 View FIGURES 4–6 ) wide and short, comparatively convex, with fine punctures. Notaulus evident on front 0.7 of mesoscutum. Scutoscutellar groove wide, with irregular short longitudinal wrinkles. Scutellum smooth, with fine sparse punctures. Postscutellum smooth, aterolateral portion with distinct pit. Mesopleuron ( Fig. 7 View FIGURES 7–9 ) with particularly dense, irregular punctures. Speculum with fine sparse punctures. Upper end of epicnemial carina reaching about 0.25 level of posterior margin of pronotum. Metapleuron with dense punctures, distance between punctures 0.2–0.5 × diameter of puncture. Juxtacoxal carina almost complete. Submetapleural carina complete. Wings slightly grayish, hyaline. Vein 1cu-a almost opposite 1/M. Vein 3rs-m distinct, but very weak. 2rs-m and 3rs-m slightly convergent forward. Areolet ( Fig. 8 View FIGURES 7–9 ) receiving vein 2m-cu at apical 0.4. Hind wing vein 1-cu about as long as cu-a. Dorsal profile of hind coxa with distinct fine sparse punctures. Ratio of length of hind tarsomeres: 8.6:3.8:2.5:1.0:2.5. Hind claw simple. Propodeum ( Fig. 9 View FIGURES 7–9 ) evenly convex, with dense, uneven punctures, anterior and posterior transverse carinae strong, complete, the latter evenly, slightly arched forward; pleural carinae distinct except apical section; area basalis present; spiracle small, oval, longest diameter 1.5 × as long as its shortest diameter.

Metasoma. First tergite 3.4 × as long as apical width, smooth, petiole flat, lateral portion of postpetiole with sparse fine punctures; spiracle small, obliquely elliptic, at posterior 0.35. Second tergite ( Fig. 10 View FIGURES 10–11 ) evenly convex, 1.4 × as long as apical width; granulose texture. Third tergite 0.8 × as long as apical width, anterior portion with similar texture as that of second tergite, posterior with shagreened surface. Fourth and subsequent tergites finely shagreened. Ovipositor sheath approximately 0.9 × as long as hind tibia. Ovipositor compressed, apical portion of ventral valve ( Fig. 11 View FIGURES 10–11 ) with very sparse, indistinct vertical ridges.

Coloration ( Fig. 1 View FIGURE 1 ). Black, except the following. Scape, pedicel, dorsal profiles of first to third flagellomeres brown, ventral yellowish brown; dorsal profiles of basal half of sixth, seventh–tenth flagellomeres white, remain- der black brown. Subapical portion of mandible red brown. Maxillary and labial palpi, fore and middle coxae and trochanters, dorsal portions of tergites 7, 8 yellowish white. The remainder of fore and middle femora and tibiae yellowish brown. Propodeum, metapleuron, hind coxa except dorsal blackish spot, trochanter, femur except apex, apical half of first tergite, second and third tergites except basal transverse blackish bands brown. Middle tarsi, hind trochantellus and main portions of tibiae indistinctly and tarsi brownish black. Ventrobasal portion of hind tibiae darkish brown.

Male. Similar to female. Body length 5.9–6.7 mm. Fore wing length 3.8–4.2 mm. Antenna with 30–31 flagellomeres. Ventrobasal portions of flagellomeres brown, the remainder brownish black. Propodeum of male sometimes partly or entirely black. Apical halves of metasomal tergites 2–5 reddish to yellowish brown.

Distribution. CHINA: Shangdong.

Etymology. The specific name is derived from the locality of type.

Remarks. Relatively similar to H. pulchra Kasparyan & Ruíz, 2005 , but can be distinguished from the latter by the following key.

The new species can be inserted as follows in Kasparyan and Ruíz-Cancino’s (2005) key to species, with the third couplet modified.
