Figs. 25–26
Material examined. Holotype: female, Zhejiang, Xitianmushan, VI.1983, Shi Zuhua, No 830388 (ZJUH).
Description. Female (Fig. 25) holotype. Body length 6.0 mm, fore wing length 4.5mm.
Head. Antenna with 32 flagellomeres; first flagellomere 1.3× longer than second flagellomere. Face (Fig. 26E) granulose. Clypeus (Fig. 26E) with minute punctures, mat, slightly convex, apical margin widely arched, slightly thick medially. Malar space granulose, 0.7× basal width of mandible. Mandible without lamella, upper tooth equal to the length of lower tooth. Frons granulose, median carina present. Vertex granulose. Interocellar distance (Fig. 26F) 1.75× ocello-ocular distance and 2.3× distance between median and lateral ocelli. Temple granulose, mat. Occipital carina evenly arched, reaching hypostomal carina at mandible base.
Mesosoma. Pronotum punctate dorsally, polished, trans-striate below. Mesoscutum (Fig. 26G), scutellum and metanotum granulose. Mesopleuron (Fig. 26B) granulose-punctate, punctures dense and separated less than their diameter, trans-striate below tegula, speculum smooth and shiny. Metapleuron punctate, punctures sparser than that on mesopleuron. Propodeum (Fig. 26C) with area basalis trapezoid; area superomedia granulose; area petiolaris trans-striate; area superomedia confluent with area petiolaris, not depressed; all carina developed; propodeal spiracle small and oval.
Wing. Fore wing (Fig. 26A) areolet present and with a short stalk emitting 2m-cu vein from its apical part. Marginal cell short, distal part of surrounding vein 2.0× longer than proximal one. Vein 1cu-a opposite M&RS. External angles of second discal cell acute (60°). Hind wing with nervellus inclivous, intercepted at lower 0.3 of its length.
Legs. Hind femur 4.7× longer than wide. Inner spur of hind tibia 0.5× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.
Metasoma. First metasomal segment (Fig. 26H) round in cross-section of basal 0.3, without dorso-lateral carina and lateral groove. First tergite 2.5× length of width of postpetiole. Postpetiole and second tergite granulose, mat. Second tergite 0.8× as long as first tergite, 1.3× longer than its apical width; thyridium round, its distance from basal margin of tergite 2.0× its diameter. Third tergite as long as its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.5× longer than hind femur, ovipositor (Fig. 26D) gradually upcurved.
Colour. Black. Mandible except teeth, palpi, scape and pedicel in front, fore and mid legs entirely and tegula, yellow with femora and tibiae orange yellow; hind coxa black, trochanter blackish brown, trochantellus, femur and tibia yellowish brown, tibia infuscated at base and apex, tarsus brown; first metasomal segment entirely, second tergite entirely, third tergite except laterally, and remainder tergites dorso-medially, black; lateral surface of metasoma from third tergite on yellowish brown.
Distribution. China (Zhejiang).
Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. manaliensis Gupta & Maheshwary, 1977, but differs from the latter by having mesopleuron densely punctate, metapleuron punctate, median longitudinal and lateral longitudinal carinae distinctly developed, pronotum shiny dorsally, and lateral surface of metasoma from third tergite on yellowish brown.
Etymology. Name derived from “densus” (Latin for “dense”) and “punctatus” (Latin for “punctate”), because its mesopleuron is densely punctate.
