Figs. 81–82

Material examined. Holotype: female, Xizang, Yangzhuoyongchuo , 15.VII.2015, 3048m, N29.79°, E93.91°, 15.VII.2015, Liu Zhen, No201409026 ( ZJUH).

Description. Female ( Fig. 81 ) holotype. Body length 9.0 mm, fore wing length 6.2 mm.

Head. Antenna with at least 30 flagellomeres (apical segments missing); first flagellomere 1.3× longer than second flagellomere. Face ( Fig. 82E ) rugose-punctate. Clypeus ( Fig. 82E ) rugose-punctate, slightly convex, apical margin arched, blunt. Malar space nearly smooth, 0.5× basal width of mandible. Mandible with lamella, upper tooth equal to the length of lower tooth. Frons rugose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 82F ) 1.3× ocello-ocular distance and 1.7× distance between median and lateral ocelli. Temple granulose, subpolished, not swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina at mandible base.

Mesosoma. Pronotum rugulose-punctate dorsally, mat, trans-striate below. Mesoscutum ( Fig. 82G ) granulosepunctate, becoming rugose in notaulic region. Scutellum granulose-punctate anteriorly, rugose posteriorly. Metanotum rugose. Mesopleuron ( Fig. 82B ) punctate, trans-striate below tegula, speculum smooth and shiny, rugose above mesopleural fovea. Metapleuron ( Fig. 82B ) rugose-punctate. Propodeum ( Fig. 82C ) with area basalis trapezoid; area superomedia rugulose, subpolished; area petiolaris trans-striate; area superomedia confluent with area petiolaris, with a moderately groove medially; all carinae developed; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 82A ) 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 slightly distad of M&RS. External angles of second discal cell acute (60°). Hind wing with nervellus inclivous, intercepted at lower 0.1.

Legs. Hind femur 5.0× longer than wide. Inner spur of hind tibia 0.55× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.

Metasoma. First metasomal segment ( Fig. 82H ) round in cross-section of basal 0.3, dorso-lateral carina and lateral groove present. First tergite 2.8× longer than width of postpetiole. Second tergite 0.75× as long as first tergite, 1.3× longer than its apical width; thyridium oval, its distance from basal margin of tergite 2.0× its length. Third tergite 1.4× longer than its width. Metasoma from third tergite on strongly compressed. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 2.2× longer than hind femur, ovipositor ( Fig. 82D ) gradually upcurved.

Colour. Black. Mandible medially yellowish brown; scape and pedicel blackish brown; tegula yellowish brown; fore leg entirely yellowish brown except coxa brown; mid leg yellowish brown except coxa and telotarsus brown; hind coxa black, trochanter, trochantellus, tibia basally and apically and tarsus blackish-brown, femur and tibia medially reddish brown; metasoma entirely black.

Distribution. China (Xizang).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. homonae Gupta & Maheshwary, 1977 , but differs from the latter by having face and clypeus rugose-punctate, pronotum rugulosepunctate dorsally, prepectal carina without a notch-like constriction, areolet relatively large and higher than stalk, and mandible yellowish brown medially.

Etymology. Name derived from the name of type locality of species.
