Description. Female ( Fig. 65 ) holotype. Body length 9.0 mm, fore wing length 5.5 mm.

Head. Antenna with 44 flagellomeres; first flagellomere 1.4× longer than second flagellomere. Face ( Fig. 66E ) rugose-punctate, weak laterally. Clypeus ( Fig. 66E ) punctate, truncated apically. Malar space granulose, 0.45× basal width of mandible. Mandible without lamella, upper tooth equal to the length of lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 66F ) 2.0× ocello-ocular distance and 2.0× distance between median and lateral ocelli. Temple granulose, mat, not swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina above mandible base.

Mesosoma. Pronotum rugose-punctate dorsally, subpolished, trans-striate below. Mesoscutum ( Fig. 66G ) granulose-punctate. Scutellum punctate, becoming rugose posteriorly. Metanotum rugose-punctate. Mesopleuron ( Fig. 66B ) punctate, trans-striate below tegula, speculum smooth and shiny. Metapleuron ( Fig. 66B ) punctate, punctures denser than that on mesopleuron. Propodeum ( Fig. 66C ) with area basalis triangular; area superomedia trans-striate, subpolished; area petiolaris trans-striate; area superomedia confluent with area petiolaris, not depressed; all carina distinctly developed; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 66A ) areolet present and with a short stalk emitting 2m-cu vein from its apical part. Marginal cell short, distal part of surrounding vein 1.9× longer than proximal one. Vein 1cu-a slightly distad of M&RS. External angles of second discal cell acute (70°). Hind wing with nervellus inclivous, intercepted at lower 0.3.

Legs. Hind femur 5.0× longer than wide. Inner spur of hind tibia 0.6× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.

Metasoma. First metasomal segment ( Fig. 66H ) round in cross-section of basal 0.3, without dorso-lateral carina and lateral groove. First tergite 3.2× longer than width of postpetiole. Second tergite 0.75× as long as first tergite, 1.6× longer than its apical width; thyridium round, its distance from basal margin of tergite 3.0× its diameter. Third tergite 1.2× longer than its apical width. Sixth and seventh tergites with emarginations medially. Ovipositor sheath approx. 1.8× longer than hind femur, ovipositor ( Fig. 66D ) gradually upcurved.

Colour. Black. Mandible medially, palpi, tegula and scape in front yellowish brown; pedicel, mandible basally and back of scape brown; fore and mid legs yellowish brown except coxae black; hind leg with coxa black, trochanter brown, tibia apically infuscated, tarsus brown, remainder of hind leg yellowish brown; metasoma entirely black except second tergite dorso-apically reddish brown.

Variation. Frons with median carina absent or present; propodeal area basalis triangular to trapezoid; area superomedia rugose to trans-striate; lateral carina weak to strong; hind femur 4.5–5.0× longer than wide; metasoma second tergite 1.3–1.6× longer than its apical width.

Distribution. China (Fujian, Heilongjiang, Jilin, Liaoning, Xinjiang).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. indicus Gupta & Maheshwary, 1977 , but differs from the latter by face rugose-punctate, frons and ocellar area granulose, pronotum rugose-punctate dorsally, mesoscutum granulose-punctate, scutellum punctate, metapleuron not rugose in juxtacoxal region, nervellus inclivous, and mandible yellowish brown medially.

Etymology. Name derived from “plicatus” (Latin for “fold”) and “punctum” (Latin for “dot”), because its face is rugose-punctate.
