Description. Female ( Fig. 51 View FIGURE 51 ) holotype. Body length 6.2 mm, fore wing length 4.3 mm.

Head. Antenna with at least 34 flagellomeres; first flagellomere 1.15× longer than second flagellomere. Face ( Fig. 52E View FIGURE 52 ) granulose-punctate. Clypeus ( Fig. 52E View FIGURE 52 ) punctate, punctures larger than that on face, slightly convex, apical margin arched, thick medially. Malar space granulose, 0.5× basal width of mandible. Mandible with lamella basally, upper tooth equal to the length of lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 52F View FIGURE 52 ) 1.5× ocello-ocular distance and 1.9× distance between median and lateral ocelli. Temple granulose, subpolished. Occipital carina evenly arched, reaching hypostomal carina above mandible base.

Mesosoma. Pronotum punctate dorsally, subpolished, trans-striate below. Mesoscutum ( Fig. 52G View FIGURE 52 ) granulose punctate, becoming rugose in notaulic region anteriorly. Scutellum with sparse and minute punctures, rugose posteriorly. Metanotum rugose-punctate. Mesopleuron ( Fig. 52B View FIGURE 52 ) punctate, trans-striate below tegula, speculum smooth and shiny. Metapleuron ( Fig. 52B View FIGURE 52 ) punctate. Propodeum ( Fig. 52C View FIGURE 52 ) with area basalis triangular, long and narrow; area superomedia granulose medially and short rugose laterally, polished; area petiolaris trans-striate; area superomedia confluent with area petiolaris, slightly depressed; all carina distinctly developed; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 52A View FIGURE 52 ) areolet present and with a moderate 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 (65°). Hind wing with nervellus inclivous, intercepted at lower 0.3 of its length.

Legs. Hind femur 4.0× 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. 52H View FIGURE 52 ) round in cross-section of basal 0.3, with weak dorso-lateral carina, and with a shallow groove. First tergite 2.5× longer than width of postpetiole. Postpetiole and second tergite granulose, mat. Second tergite 0.6× as long as first tergite, 0.85× its apical width; thyridium round, its distance from basal margin of tergite equal to its diameter. Third tergite 0.8× as long as its apical width. Metasoma not compressed apically. Sixth and seventh tergites without emarginations. Ovipositor sheath approx. 1.7× longer than hind femur, ovipositor ( Fig. 52D View FIGURE 52 ) 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 unicolorous, slightly infuscated apically, tarsus brown; metasoma entirely black with second and third segments slightly blackish brown.

Variation. First flagellomere 1.1–1.25× second flagellomere; face granulose to granulose-punctate; frons with median carina absent or present; pronotum granulose-punctate to punctate dorsally; specimens from Shenyang province with ovipositor thinner; scape and pedicel entirely brown or yellowish-brown anteriorly; specimens from Henan province with hind tibia banded.

Distribution. China ( Guangdong, Henan, Jinlin, Neimeng, Shaanxi, Shenyang, Zhejiang).

Comparative diagnosis. This new species is similar to C. proportionis sp. nov., but differs from the latter by having second tergite 0.8–0.9× as long as its apical width, thyridium separated from the basal margin of tergite by its diameter, metasoma not compressed apically, malar space and frons granulose, and metanotum rugose-punctate.

Etymology. Name derived from “mono-” (Greek for “single”), and “chroma” (Greek for “colour”), because its hind tibia is unicolorous.
