Type material
Holotype, ♀ (NWUX): “NW. China: Shaanxi, Guanghuojie, Qinling Mts, c. 1000 m, 27.vi.2013, Jiangli Tan, NWUX”. Paratype: 1 ♂ (ZJUH): “[China:] Shaanxi, Liuba, Mt. Zibai, 1632 m, 4.viii.2004, Zhang Hong-ying, No. 20047080”.
Diagnosis
Head in dorsal view parallel-sided behind eyes (Fig. 19); posterior half of pronotum comparatively low and dorso-posteriorly finely transversely rugose (Fig. 13); first subdiscal cell of fore wing comparatively robust and 2.0–2.5 times longer than wide (Fig. 12); hind coxa with strong and sparse rugae, and without dorsal tooth (Figs 18, 23); first-third metasomal tergites black or dark brown (Fig. 11); first metasomal segment narrow in lateral view (Fig. 30); first tergite 3.8-4.6 times (♀♂) as long as its maximum width and irregularly coarsely transversely rugose (Fig. 15).
Description
Holotype, female, length of body 12.4 mm, and of fore wing 9.2 mm.
Head. Antenna with 30 segments; frons coarsely obliquely rugose; three anterior coronal teeth large and acute, both posterior ones arcuate and lamelliform, with two small lobe-shaped carinae on each side in front of both posterior ocelli; behind level of coronal area having four curved, progressively smaller carinae followed by rugose area, rugae rather coarse, posteriorly narrowly reaching occipital carina and widely smooth laterally; temple non-angulate (Fig. 19), punctulate but largely smooth and shiny.
Mesosoma. Neck short and robust, transversely rugose, neck at much lower level than middle part of pronotum (Fig. 14); middle part of pronotum largely smooth and without a distinct carina posteriorly; propleuron with sparse large punctures, shiny and rather densely setose; mesonotum irregularly foveolate and area between smooth; notauli and median groove distinct; scutellum with some coarse punctures medially, foveolate laterally; axillae coarsely punctate; mesopleuron distinctly convex, convex part foveolate-punctate and covered with long whitish setae, medially convex part of metapleuron rugose and with long whitish setae, anteriorly crenulate and intermediate area smooth; propodeum densely irregularly rugose (Fig. 14).
Wings. Fore wing (Fig. 12): vein 1-M 3.4 times as long as vein 1-SR and curved; vein r ends slightly before level of apex of pterostigma; first subdiscal cell robust, 2.2 times as long as its maximum width, vein cu-a entirely pigmented.
Legs. Hind coxa robust, without tubercle dorsally and with strong and sparse rugae (Figs 18, 23); hind femur widened, sparsely punctate and with whitish setae ventrally and dark brown setae dorsally, area in between punctures smooth and shiny, ventrally with 3 large acute teeth (the anterior one much smaller than posterior ones) and several denticles in between (Fig. 16); hind tibia 1.3 times as long as hind femur, basal narrow part of hind tibia about 0.8 times as long as widened part, widened part ventrally distinctly obliquely carinate; hind basitarsus subparallel-sided, length of hind basitarsus 3.7 times as long as wide and 1.3 times as long as second tarsal segment.
Metasoma. First tergite 3.8 times as long as its maximum width (Fig. 15), 1.2 times as long as second tergite and 0.4 times as long as metasoma without first tergite, sub-cylindrical, distinctly transversely rugose, but medially irregularly rugose; base of second tergite finely sparsely rugose; remainder of tergites smooth and shiny; setose part of ovipositor sheath 1.7 times as long as body and 2.3 times as long as fore wing.
Colour. Black or blackish brown; tegula and palpi dark brown; scapus, pedicellus, malar space, mandible and patch near basal quarter of hind tibia partly brown; base of femora and of fore and middle tibiae and tarsi pale yellowish brown; remainder of fore and middle tibiae brown; veins and pterostigma largely dark brown, but base of pterostigma ivory; wing membrane slightly brownish but fore wing darkened near vein r and below parastigma; subapical ivory band of ovipositor sheath 1.9 times as long as apical blackish part (Fig. 22).
Male. See Hong et al. (2011)[2] for a detailed description. It has the first tergite 4.6 times as long as its maximum width.
Distribution
Palaearctic: China (Shaanxi).
Etymology
Named after Ms Chundan Hong (Guangzhou), who revised the Chinese species of the Stephanidae.
