Figs. 33–34

Material examined. Holotype: female, Xizang, Xiayadong, 19.VII.2013, Liu Zhen, No 201400874 ( ZJUH).

Description. Female ( Fig. 33 ) holotype. Body length 5.0 mm, fore wing length 3.7 mm.

Head. Antenna with 31 flagellomeres; first flagellomere 1.3× longer than second flagellomere. Face ( Fig. 34E ) granulose. Clypeus ( Fig. 34E ) granulose, slightly convex, apical margin arched, blunt. Face and clypeus combined equal to minimum width of face. Malar space granulose, 0.8× 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. 34F ) 1.0× ocello-ocular distance and 1.6× distance between median and lateral ocelli. Temple nearly smooth, subpolished, not swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina at mandible base.

Mesosoma. Pronotum granulose-punctate dorsally, subpolished, trans-striate below. Mesoscutum ( Fig. 34G ) granulose, notauli indistinct. Scutellum and metanotum granulose. Mesopleuron ( Fig. 34B ) granulose, weakly trans-striate below tegula, speculum smooth and shiny. Metapleuron ( Fig. 34B ) granulose. Propodeum ( Fig. 34C ) with area basalis triangular; area superomedia confluent with area petiolaris, trans-striate, slightly depressed; medio-longitudinal carina very weak; latero-longitudinal carina absent; propodeal spiracle small and round.

Wing. Fore wing ( Fig. 34A ) areolet present and without stalk, emitting 2m-cu vein from its apical part. Marginal cell short, distal part of surrounding vein 1.7× 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 0.35.

Legs. Hind femur 5.0× longer than wide. Inner spur of hind tibia 0.57× as long as first tarsomere of hind tarsus. Tarsal claws pectinate, its teeth weak.

Metasoma. First metasomal segment ( Fig. 34H ) round in cross-section of basal 0.3, with weak dorso-lateral carina anteriorly and without lateral groove. First tergite 2.5× longer than width of postpetiole. Postpetiole and second tergite granulose, finely granulose on subsequent tergites, subpolished. Second tergite 0.75× as long as first tergite, 1.3× longer than its apical width; thyridium round, its distance from basal margin of tergite 1.5× its diameter. Third tergite as long as its apical width. Sixth and seventh tergites with weak emarginations medially. Ovipositor sheath approx. 1.3× longer than hind femur, ovipositor ( Fig. 34D ) gradually upcurved.

Colour. Black. Mandible except teeth, palpi and tegula yellow; scape and pedicel blackish brown; fore coxa basally, dorsal surface of tibia and tarsus brown, trochanter and trochantellus yellow, remainder of fore leg yellowish brown; mid coxa basally, femur dorsally, tibia basally and apically, and tarsus brown, trochanter and trochantellus yellow, remainder of mid leg yellowish brown; hind coxa black, trochanter, trochantellus basally, femur, tibia basally and apically and tarsus blackish brown, trochantellus apically and tibia medially yellowish brown; metasoma from third tergite on yellowish brown laterally.

Distribution. China (Xizang).

Comparative diagnosis. This species is similar to C. pseudocollinus Gupta & Maheshwary, 1977 , but differs from the latter by having face and clypeus combined equal to minimum width of face, malar space granulose, 0.8× basal width of mandible, propodeal area superomedia trans-rugose, fore wing areolet large and without stalk, hind wing with nervellus inclivous, and body color different.

Etymology. Name derived from “grandis” (Latin for “large”) and “cella” (Latin for “cell”), because its fore wing areolet is large.
