Description. Female ( Fig. 75 ) holotype. Body length 7.8 mm, fore wing length 5.5 mm.

Head. Antenna with 37 flagellomeres; first flagellomere 1.4× longer than second flagellomere. Face ( Fig. 76E ) rugose, weak laterally. Clypeus ( Fig. 76E ) granulose-punctate, convex, apical margin slightly arched. Malar space granulose, 0.5× basal width of mandible. Mandible with lamella, upper tooth equal to the length of lower tooth. Frons rugose, median carina present. Vertex granulose. Interocellar distance ( Fig. 76F ) 2.0× ocello-ocular distance and 2.0× distance between median and lateral ocelli. Temple granulose, mat, not swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina at mandible base.

Mesosoma. Pronotum punctate dorsally, subpolished, trans-striate below. Mesoscutum ( Fig. 76G ) granulosepunctate, becoming rugose in notaulic region. Scutellum and metanotum rugose-punctate. Mesopleuron ( Fig. 76B ) rugose-punctate, trans-striate below tegula, striations extending to prepectal carina, speculum smooth and shiny. Metapleuron ( Fig. 76B ) granulose-punctate, rugose ventrally. Propodeum ( Fig. 76C ) with area basalis trapezoid; area superomedia rugose; area petiolaris trans-striate; area superomedia confluent with area petiolaris, with a deep groove medially; all carina distinctly developed; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 76A ) 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 0.1.

Legs. Hind femur 4.6× 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. 76G ) round in cross-section of basal 0.3, without dorso-lateral carina and lateral groove. First tergite 3.0× longer than width of postpetiole. Second tergite 0.75× as long as first tergite, 1.4× longer than its apical width; thyridium round, its distance from basal margin of tergite 1.5× its diameter. Metasoma from third tergite on strongly compressed. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.8× longer than hind femur, ovipositor ( Fig. 76D ) gradually upcurved.

Colour. Black. Mandible except teeth yellowish brown; scape and pedicel brown; tegula whitish yellow; fore leg entirely yellow except coxa basally and telotarsus brown; mid leg yellow except coxa and telotarsus brown; hind coxa blackish brown, trochanter, trochantellus, tibia basally and apically, tarsus except basal tarsomere 0.8 brown, femur reddish brown, tibia medially and basal tarsomere 0.8 yellowish brown; first tergite and second tergite except apically black, second tergite apically and third tergite apico-laterally reddish brown, remainder of metasoma brown.

Variation. Second metasomal tergite 1.4–2.2× longer than its apical width; thyridium 1.5–3.0× its diameter separated from the base of second tergite; scape and pedicel yellowish-brown to brown.

Distribution. China (Heilongjiang, Liaoning, Zhejiang).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. sticticus Gupta & Maheshwary, 1977 , but differs from the latter by having pronotum punctate dorsally, metapleuron rugose-punctate, nervellus inclivous and intercepted at lower 0.1, and first metasomal segment without dorso-lateral carina and lateral groove.

Etymology. Name derived from “strigis” (Latin for “groove”), because its propodeum has a deep groove medially.
