Description. Female ( Fig. 9 ) holotype. Body length 7.3 mm, fore wing length 4.8 mm.

Head. Antenna with 40 flagellomeres; first flagellomere 1.5× longer than second flagellomere. Face ( Fig. 10E ) granulose. Clypeus ( Fig. 10E ) granulose with sparse punctures, slightly convex, apical margin almost truncated. Malar space granulose, 0.45× basal width of mandible. Mandible with a very weak lamella, upper tooth equal to the length of lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 10F ) 1.7× ocello-ocular distance and 2.5× distance between median and lateral ocelli. Temple granulose, subpolished. Occipital carina evenly arched, reaching hypostomal carina slightly above mandible base.

Mesosoma. Pronotum granulose with sparse punctures dorsally, subpolished, trans-striate below. Mesoscutum ( Fig. 10G ) granulose punctate, rugose in notaulic region. Scutellum granulose-punctate. Metanotum granulose. Mesopleuron ( Fig. 10B ) granulose-punctate, becoming rugose above mesopleural fovea, trans-striate below tegula, speculum smooth and shiny. Metapleuron granulose. Propodeum ( Fig. 10C ) with area basalis trapezoid; area superomedia area confluent with area petiolaris, deeply depressed medially; area petiolaris trans-striate medially; median carina absent under costula, present posteriorly; latero-longitudinal carina weakly developed; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 10A ) areolet present and with a short stalk emitting 2m-cu vein from its apical part. Marginal cell short, distal part of surrounding vein 1.8× longer than proximal one. Vein 1cu-a opposite M&RS. External angles of second discal cell acute (70°). Hind wing with nervellus slightly inclivous, intercepted at lower 0.15.

Legs. Hind femur 5.3× longer than wide. Inner spur of hind tibia 0.5× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.

Metasoma. Mat. First metasomal segment ( Fig. 10H ) round in cross-section of basal 0.3, dorso-lateral carina and lateral groove present. First tergite 3.2× longer than width of postpetiole. Second tergite 0.86× as long as first tergite, 1.8× longer than its apical width; thyridium oval, its distance from basal margin of tergite 3.5× its diameter. Third tergite 1.3× longer than its apical width. Sixth and seventh tergites with emarginations medially. Ovipositor sheath approx. 1.6× longer than hind femur, ovipositor ( Fig. 10D ) gradually upcurved.

Colour. Black. Mandible except teeth, palpi and tegula, yellowish brown; scape and pedicel brown; fore and mid legs yellowish brown with coxa brown; hind leg with coxa and trochanter black, trochantellus and tibia medially yellowish brown, femur blackish brown, remainder of hind leg brown; metasoma with second tergite apically and from third tergite on laterally brown, remainder of metasoma black.

Variation. Antenna with 34–40 flagellomeres; first flagellomere 1.3–1.5× longer than second flagellomere; malar space 0.3–0.45× basal width of mandible; interocellar distance 1.3–1.7× ocello-ocular distance and 1.7–2.5× distance between median and lateral ocelli; hind femur 4.4–5.3× longer than wide; first tergite 3.0–3.2× longer than width of postpetiole; second tergite 0.8–0.9× as long as first tergite, 1.5–1.8× longer than its apical width; third tergite 0.9–1.3× longer than its apical width; ovipositor sheath 1.5–1.7× longer than hind femur.

Distribution. China (Anhui, Fujian, Guangxi, Guizhou, Hebei, Heilongjiang, Jilin, Jiangsu, Jiangxi, Liaoning, Shandong, Sichuan, Zhejiang).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. oriens Gupta & Maheshwary, 1977 , but differs from the latter by having interocellar distance 2.5× distance between median and lateral ocelli, mesopleuron granulose-punctate, propodeal median area deeply depressed, fore and mid legs with coxae brown, and hind femur blackish brown.

Etymology. Name derived from “angustus” (Latin for “narrow”) and “aulacis” (Latin for “furrow”), because its propodeal median area has a narrow groove.
