Figs. 61–62
Material examined. Holotype: female, Fujian, Fuzhou, 11.IV.1991, Liu Changming, No966415 (ZJUH).
Description. Female (Fig. 61) holotype. Body length 6.8 mm, fore wing length 4.8 mm.
Head. Antenna with at least 16 flagellomeres (apical segments missing); first flagellomere equal to the length of second flagellomere. Face (Fig. 62E) granulose-punctate medially, punctate around. Clypeus (Fig. 62E) punctate, slightly convex, apical margin arched. Malar space shallowly punctate, 0.5× basal width of mandible. Mandible with lamella basally, upper tooth equal to the length of lower tooth. Frons rugose-punctate, median carina absent. Vertex granulose. Interocellar distance (Fig. 62F) 1.5× ocello-ocular distance and 1.7× distance between median and lateral ocelli. Temple nearly smooth, subpolished. Occipital carina narrowly curved dorsally, reaching hypostomal carina above mandible base.
Mesosoma. Pronotum punctate dorsally, subpolished, trans-striate below. Mesoscutum (Fig. 62G) granulose punctate, becoming rugose in notaulic region. Scutellum with sparse and minute punctures. Metanotum shallowly punctate. Mesopleuron (Fig. 62B) punctate, trans-striate below tegula, speculum smooth and shiny. Metapleuron (Fig. 62B) punctate, rugose on the region before hind coxa. Propodeum (Fig. 62C) with area basalis triangular, long and narrow; area superomedia granulose, polished; area petiolaris trans-striate; area superomedia confluent with area petiolaris, not depressed; all carina distinctly developed; propodeal spiracle small and round.
Wing. Fore wing (Fig. 62A) 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 (50°). Hind wing with nervellus inclivous, intercepted at lower 0.3 of its length.
Legs. Hind femur 4.1× longer than wide. Inner spur of hind tibia 0.4× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.
Metasoma. First metasomal segment (Fig. 62H) round in cross-section of basal 0.3, with weak dorso-lateral carina basally, and with a shallow groove. First tergite 3.0× longer than width of postpetiole. Postpetiole and second tergite granulose, mat. Second tergite 0.7× as long as first tergite, 1.25× longer than its apical width; thyridium round, its distance from basal margin of tergite 2.0× its diameter. Third tergite equal to its apical width. Metasoma compressed from third segment on. Sixth and seventh tergites with weak emarginations medially. Ovipositor sheath approx. 2.0× longer than hind femur, ovipositor (Fig. 62D) gradually upcurved.
Colour. Black. Mandible except teeth, palpi, fore and middle legs entirely and tegula, yellow with telotarsus brownish; scape and pedicel yellowish brown anteriorly and brown dorsally; hind coxa black, trochanter except basally, femur and tibia yellowish brown, tibia infuscated subbasally and apically, tarsus blackish brown; metasoma entirely black.
Distribution. China (Fujian).
Comparative diagnosis. This new species is similar to C. bazariae Sheng, 2014, but differs from the latter by having face granulose-punctate medially and mat, clypeus mat, first flagellomere equal to the length of second flagellomere, notauli present and rugose, scutellum sparsely punctate, vein 1cu-a opposite M&RS, area superomedia granulose, first metasomal tergite with weak dorso-lateral carina and a shallow groove, sixth and seventh metasomal tergites without median emarginations, fore and mid coxae yellow, and mid and hind femur entirely yellowish brown.
Etymology. Name derived from “proportionis” (Latin for “relative equality”), because the length of the first flagellomere is equal to that of the second flagellomere.
