Description. Female (Fig. 83) holotype. Body length 6.3 mm, fore wing length 4.0 mm.

Head. Antenna with 34 flagellomeres; first flagellomere 1.35× longer than second flagellomere. Face (Fig. 84E) strongly granulose. Clypeus (Fig. 84E) mat, slightly convex, apical margin slightly curved. Malar space granulose, 0.6× basal width of mandible. Mandible with lamella. Frons granulose, median carina absent. Vertex granulose. Interocellar distance (Fig. 84F) 1.45× ocello-ocular distance and 2.0× distance between median and lateral ocelli. Temple nearly smooth, subpolished. Occipital carina evenly arched, reaching hypostomal carina at mandible base.

Mesosoma. Pronotum granulose dorsally, trans-striate below. Mesoscutum (Fig. 84G) granulose. Scutellum granulose with posterior rugose. Metanotum rugose-punctate. Mesopleuron (Fig. 84B) granulose-punctate, transstriate below tegula, speculum smooth and shiny. Metapleuron (Fig. 84B) granulose with sparse and minute punctures. Propodeum (Fig. 84C) with anterior transverse carina close to base; area superomedia granulose; area petiolaris trans-striate; area superomedia confluent with area petiolaris, slightly depressed medially; all carina strong; propodeal spiracle small and oval.

Wing. Fore wing (Fig. 84A) 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 inclivous, intercepted at lower 0.25 of its length.

Legs. Hind femur 4.5× longer than wide. Inner spur of hind tibia 0.52× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.

Metasoma. First metasomal segment (Fig. 84H) round in cross-section of basal 0.3, with weak dorso-lateral carina and a shallow lateral groove. Postpetiole and second tergite granulose. Second tergite 0.73× as long as first tergite, 1.7× longer than its apical width; thyridium oval, small, its distance from basal margin of tergite 3.0× its length. Third tergite 1.1× longer than its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 2.0× longer than hind femur, ovipositor (Fig. 84D) gradually upcurved.

Colour. Black. Mandible except teeth, malar space, palpi and tegula, yellowish brown; all coxae and hind trochanter, black; remainder of leg yellowish brown with base and apex of hind tibia, apical segments of fore and middle tarsus and whole of hind tarsus, infuscated; metasoma entirely black.

Male. Propodeal carina stronger and surface structure of propodeum coarser; otherwise similar to female.

Variation. Propodeal lateral carina weak to strong, second metasomal tergite 1.7–2.0× longer than its apical width.

Distribution. China (Fujian, Guangdong, Guangxi, Guizhou, Hubei, Shanxi, Sichuan, Yunnan, Zhejiang).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. anatolus Gupta & Maheshwary, 1977, but differs from the latter by having the malar space yellowish brown, all propodeal carinae strong, and punctures of mesopleuron dorsally larger and denser than in C. anotolus .

Etymology. Name derived from “xuthos” (Greek for “yellowish brown”) and “melon” (Greek for “cheek”), because its malar space is yellowish brown.
