Description. Holotype: ♀. Length 17.5 mm ( Fig. 1 View FIGURE 1 f). Body deep black; mesoscutal middle lobe entirely, lateral lobe except for narrow lateral margin, mesoscutellum except for narrow posterior margin, red; body hairs black brown, hairs on red part of mesonotum golden. Wings strongly and evenly infuscate, vein R1 largely brown, pterostigma and other veins black; hind wing slightly paler than forewing.

Clypeus densely punctured, interspaces between punctures narrow and smooth, shiny; inner orbit, temple and postocellar area with fine surface microsculpture, weakly shiny; frons densely microsculptured with some minute punctures; malar space densely microsculptured, hind orbit with dense and minute punctures; mesoscutal middle lobe and lateral lobe indistinctly punctured, mesoscutellum minutely punctured in anterior 0.75 and densely punctured in posterior margin; mesoscutellar appendage (posttergite) smooth and glabrous, strongly shiny; punctures minute and rather dense on upper corner of mesepisternum, and gradually larger and sparser toward ventral side, surface indistinctly microsculptured, shiny; depressed area of mesepimeron and of metapleuron densely microsculptured, broad posterior margin of mesepimeron and of metepimeron smooth and strongly shiny; abdominal tergites 1–2 sparsely and minutely punctured, interspaces microsculptured, shiny; tergites 3–10 densely and minutely punctured, interspaces microsculptured, weakly shiny; intertergites smooth, strongly shiny.

Antenna as long as head and thorax together, not incrassated beyond middle, 5th –9th antennomeres with shallow but distinct longitudinal furrow in both sides, third antennomere about 0.9 times as long as following two antennomeres together, 7th antennomere about 2.3 times as long as broad ( Fig. 3 View FIGURE 3. a g). Mesoscutellum strongly and triangularly protruding; mesoscutellar appendage flat, without middle carina, posterior half with a short and shallow middle furrow; cenchrus transverse and elliptical, much broader than long, CD = 1.9. Venation as Fig. 1 View FIGURE 1 f, anal cross vein present; petiole of hind anal cell about 0.4 times length of cu-a. Claw as Fig. 3 View FIGURE 3. a d. Ovipositor sheath 1.1 times as long as front tibia, apical sheath as long as basal sheath, distinctly tapering toward apex, apex narrowly round ( Fig. 2 View FIGURE 2. a – c o); sheath and setae in dorsal view as Fig. 2 View FIGURE 2. a – c l, sheath distinctly broadened toward apex, about 4 times as broad as breadth of cercus; cercus slender, about 4 times as long as broad. Lancet as Fig. 4 View FIGURE 4 c, with 17 serrulae, middle and apical segments of lancet as Figs 4 View FIGURE 4 i, f, annular spines long and dense; surface sculpture of lancet as Figs 4 View FIGURE 4 m, n.

Male. Body length 15 mm ( Fig. 1 View FIGURE 1 g); color, punctation and structure similar to female except for following: malar space 0.3 times as long as diameter of median ocellus ( Fig. 2 View FIGURE 2. a – c i); distance between eyes at level of anterior tentorial pits as long as longest axis of eye; head distinctly narrowed behind eyes in dorsal view; subgenital plate broader than long, apical margin broadly truncate; harpes 1.9 times as long as broad ( Fig. 5 View FIGURE 5 c); volsella and gonolacinia as Figs 5 View FIGURE 5 h, i; penis valve as Figs 5 View FIGURE 5 p–r.

Variation. The anal cross vein in forewing is sometimes absent in a few specimens.

Etymology. The species is named after Dr. Yihai Zhong, an early collector of some type specimens of the species.
