Figs. 53–54

Material examined. Holotype: female, Liaoning, Laotuding, 16.VII.2011, Zhao Kexin, No 201103248 ( ZJUH).

Description. Female ( Fig. 53 ) holotype. Body length 6.4 mm, fore wing length 5.3 mm.

Head. Antenna with 35 flagellomeres; first flagellomere 1.3× longer than second flagellomere. Face ( Fig. 54E ) granulose, weak laterally. Clypeus ( Fig. 54E ) granulose dorsally, smooth and shiny below, slightly convex, apical margin blunt, slightly arched. Malar space shiny, 0.4× basal width of mandible. Mandible with a weak lamella, upper tooth equal to the length of lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 54F ) 0.8× ocello-ocular distance and 1.4× distance between median and lateral ocelli. Temple granulose, subpolished, not swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina above mandible base.

Mesosoma. Pronotum granulose dorsally, polished, trans-striate below. Mesoscutum ( Fig. 54G ) granulose. Scutellum and metanotum granulose. Mesopleuron ( Fig. 54B ) granulose, trans-striate below tegula, speculum smooth and shiny, rugulose above mesopleural fovea. Metapleuron ( Fig. 54B ) granulose. Propodeum ( Fig. 54C ) with area basalis trapezoid; area superomedia granulose; area petiolaris granulose-rugulose; area superomedia confluent with area petiolaris, slightly depressed; median and lateral longitudinal carinae absent; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 54A ) 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 opposite M&RS. External angles of second discal cell acute (70°). Hind wing with nervellus slightly inclivous, intercepted at lower 0.1.

Legs. Hind femur 4.6× longer than wide. Inner spur of hind tibia 0.57× as long as first tarsomere of hind tarsus. Tarsal claws pectinate basally, teeth very weak.

Metasoma. First metasomal segment ( Fig. 54H ) round in cross-section of basal 0.3, dorso-lateral carina present, lateral groove absent. First tergite 2.5× longer than width of postpetiole. Second tergite 0.8× as long as first tergite, 1.4× longer than its apical width; thyridium oval, its distance from basal margin of tergite 1.7× its length. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.1× longer than hind femur, ovipositor ( Fig. 54D ) gradually upcurved.

Colour. Black. Mandible except teeth, palpi and tegula yellowish brown; scape and pedicel blackish brown; fore leg yellowish brown except coxa and telotarsus brown, trochanter and trochantellus yellow; mid leg yellowish brown except coxa, femur basal-ventrally and telotarsus brown, trochanter and trochantellus yellow; hind leg with extreme base of femur yellowish brown, tibia medially and basal tarsomere 0.6 whitish yellow, remainder of hind leg black; metasoma entirely black.

Distribution. China (Liaoning).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. collinus Gupta & Maheshwary, 1977 , but differs from the latter by having face granulose, interocellar distance 0.8× ocello-ocular distance and 1.4× distance between median and lateral ocelli, metapleuron granulose, and mid leg largely yellowish brown.

Etymology. Name derived from “obtusus” (Latin for “blunt”) and “clypeus” (Latin for “clypeus”), because the apical margin of the clypeus is blunt.
