Description. Female ( Fig. 35 ) holotype. Body length 4.3 mm, fore wing length 3.5 mm.

Head. Antenna with 24 flagellomeres; first flagellomere 1.2× longer than second flagellomere. Face ( Fig. 36E ) granulose. Clypeus ( Fig. 36E ) granulose, slightly convex, apical margin truncated, thick medially. Malar space granulose, 0.5× basal width of mandible. Mandible with a very weak lamella, upper tooth equal to the length of lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 36F ) 1.5× ocelloocular distance and 1.8× distance between median and lateral ocelli. Temple granulose, mat, swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina above mandible base.

Mesosoma. Pronotum granulose dorsally, mat, trans-striate below. Mesoscutum ( Fig. 36G ) granulose, notauli indistinct. Scutellum and metanotum granulose. Mesopleuron ( Fig. 36B ) granulose, weakly trans-striate below tegula, speculum smooth and shiny. Metapleuron ( Fig. 36B ) granulose. Propodeum ( Fig. 36C ) with area basalis triangular, long and narrow; area superomedia granulose, mat; 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. 36A ) without areolet. Marginal cell short, distal part of surrounding vein 2.1× longer than proximal one. Vein 1cu-a opposite M&RS. External angles of second discal cell acute (70°). Hind wing with nervellus vertical, intercepted at lower 0.25.

Legs. Hind femur 4.0× longer than wide. Inner spur of hind tibia 0.55× as long as first tarsomere of hind tarsus. Tarsal claws pectinate, its teeth weak.

Metasoma. First metasomal segment ( Fig. 36H ) round in cross-section of basal 0.3, without dorso-lateral carina and lateral groove. First tergite 2.5× longer than width of postpetiole. Postpetiole and second tergite granulose, mat. Second tergite 0.7× as long as first tergite, equal to its apical width; thyridium round, its distance from basal margin of tergite 1.5× its diameter. Third tergite 0.9× as long as its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.4× longer than hind femur, ovipositor ( Fig. 36D ) gradually upcurved.

Colour. Black. Mandible except teeth, palpi, yellow; scape and pedicel brown; tegula whitish; fore and mid trochanter and trochantellus whitish yellow, telotarsus brownish; remainder of fore and mid legs orange yellow; hind coxa black, trochanter basally blackish brown, femur and tibia yellowish brown, extreme apex of femur infuscated, tibia infuscated subbasally and apically, tarsus blackish brown except basal 0.8 yellowish brown; first metasomal segment entirely black; second tergite except apical laterally, third tergite except apically, fourth to seventh segments except laterally, blackish brown; remainder of metasoma reddish brown.

Variation. Antenna with 24–26 flagellomeres, fore wing areolet absent or present and with 3rs-m vein incomplete, length of second tergite of metasoma 1.0–1.6× its apical width, scape and pedicel yellowish brown to blackish brown.

Distribution. China (Hubei, Jilin, Neimenggu, Shandong, Xinjiang).

Comparative diagnosis. This species is similar to C. lobatus sp. nov., but differs from the latter by having first flagellomere 1.2× longer than second flagellomere, mesopleuron granulose, thyridium separated from basal margin of tergite by 1.5× its diameter, mid and hind leg largely yellowish brown, and metasoma colour different.

Etymology. Name derived from “granosus” (Latin for “granular”), because its body sculpture is largely granulose.
