Figs. 45–46

Material examined. Holotype: female, Xizang, Naqu Naixian, 31.VII.2013, Liu Zhen, No 201408822 ( ZJUH).

Description. Female ( Fig. 45 ) holotype. Body length 5.5 mm, fore wing length 4.0 mm.

Head. Antenna with 30 flagellomeres; first flagellomere 1.45× longer than second flagellomere. Face ( Fig. 46E ) granulose. Clypeus ( Fig. 46E ) granulose, convex and long, apical margin arched, sharp. Malar space granulose, 0.9× basal width of mandible. Mandible without lamella, upper tooth equal to the length of lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 46F ) 1.5× ocello-ocular distance and 1.7× distance between median and lateral ocelli. Temple granulose, subpolished, swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina above mandible base.

Mesosoma. Pronotum granulose-punctate, mat, weakly trans-striate on extremely below. Mesoscutum granulose punctate. Scutellum and metanotum granulose. Mesopleuron ( Fig. 46B ) granulose-punctate, trans-striations below tegula short and weak, speculum smooth and shiny, mesopleural fovea absent. Metapleuron ( Fig. 46B ) granulose-punctate. Propodeum ( Fig. 46C ) granulose; area basalis trapezoid; area superomedia granulose; area petiolaris granulose-rugulose; area superomedia confluent with area petiolaris, not depressed; medio-longitudinal carina present below costulae and absent apically; lateral longitudinal carina absent; other carinae present; propodeal spiracle small and short oval.

Wing. Fore wing ( Fig. 46A ) areolet present and with a long stalk emitting 2m-cu vein from its middle. Marginal cell short, distal part of surrounding vein 1.8× longer than proximal one. Vein 1cu-a slightly distad of M&RS. External angles of second discal cell vertical. Hind wing with nervellus intercepted slightly below middle.

Legs. Hind femur 5.1× longer than wide. Inner spur of hind tibia 0.44× as long as first tarsomere of hind tarsus. Tarsal claws pectinate, teeth very weak.

Metasoma. First metasomal segment ( Fig. 46H ) round in cross-section of basal 0.3, without dorso-lateral carina and lateral groove. First tergite 2.8× longer than width of postpetiole. Postpetiole and second tergite granulose. Second tergite 0.85× as long as first tergite, 1.3× longer than its apical width; thyridium oval, its distance from basal margin of tergite about its length. Third tergite equal to its apical width. Sixth and seventh tergites with emarginations medially. Ovipositor sheath approx. 2.1× longer than hind femur, ovipositor ( Fig. 46D ) gradually upcurved.

Colour. Black. Mandible except teeth yellow; palpi brown; tegula, scape and pedicel black; pterostigma whitish basally; fore coxa brown except extreme apically yellow, trochanter basally, trochantellus basally, femur ventrally, tibia dorsally and tarsus, blackish brown, remainder of fore leg yellow; mid trochantellus apically and femur extreme basally yellow, tibia medially brownish, remainder of mid leg blackish; hind leg with trochantellus apically, femur extreme basally and tibia dorso-medially brownish, remainder of hind leg black; metasoma entirely black.

Distribution. China (Xizang).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. kalatopensis Gupta & Maheshwary, 1977 , but differs from the latter by having clypeus long, mesopleuron granulose-punctate, mediolongitudinal carina absent underneath, lateral carina absent, area petiolaris granulose, the length of areolet shorter than its stalk, and body colour different.

Etymology. Name derived from “longus” (Latin for “long”) and “clypeus” (Latin for “clypeus”), because its clypeus is long.
