Figs. 29–30

Material examined. Holotype: female, Jilin, VII.1976, Zeng Haifeng, Host : Laspeyresia zebeana, No 760504 ( ZJUH) . Paratypes: 2 females, Heilongjiang, Heihe, Wan Li, No 810343 (2) ; 1 female, Zhejiang, Hangzhou, 23.IV.1987, Ma Yun, No 810433 .

Description. Female ( Fig. 29 ) holotype. Body length 6.3 mm, fore wing length 4.5 mm.

Head. Antenna with 31 flagellomeres; first flagellomere 1.1× longer than second flagellomere. Face ( Fig. 30E ) granulose-punctate. Clypeus ( Fig. 30E ) punctate, slightly convex, apical margin widely arched. Malar space granulose, 0.55× basal width of mandible. Mandible with lamella present basally, upper tooth equal to the length of lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 30F ) 1.7× ocello-ocular distance and 1.9× 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-punctate, subpolished, trans-striate below. Mesoscutum ( Fig. 30G ) granulose punctate. Scutellum and metanotum granulose, scutellum with minute punctures. Mesopleuron ( Fig. 30B ) granulose-punctate, trans-striate below tegula, speculum smooth and shiny, rugose above mesopleural fovea. Metapleuron ( Fig. 30B ) punctate. Propodeum ( Fig. 30C ) with area basalis rectangular; area superomedia granulose-rugulose; area petiolaris trans-striate; area superomedia confluent with area petiolaris, not depressed; all carina strongly developed; propodeal spiracle small and round.

Wing. Fore wing ( Fig. 30A ) areolet present and with a short stalk emitting 2m-cu vein from its apical part. Marginal cell short, distal part of surrounding vein 2.5× longer than proximal one. Vein 1cu-a distad of M&RS by 0.3 of its length. External angles of second discal cell acute (60°). Hind wing with nervellus inclivous, intercepted at lower 0.3 of its length.

Legs. Hind femur 4.6× longer than wide. Inner spur of hind tibia 0.6× as long as first tarsomere of hind tarsus. Tarsal claws pectinate, teeth very weak.

Metasoma. First metasomal segment ( Fig. 30H ) round in cross-section of basal 0.3, without dorso-lateral carina, lateral groove present but weak. First tergite 2.6× longer than width of postpetiole. Metasoma entirely granulose. Second tergite 0.6× as long as first tergite, 0.8× as long as its apical width; thyridium oval, its distance from basal margin of tergite 0.6× of its length. Third tergite 0.7× as long as its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.4× longer than hind femur, ovipositor ( Fig. 30D ) gradually upcurved.

Colour. Black. Mandible blackish brown basally, reddish brown apically, yellowish brown medially; tegula, scape and pedicel blackish brown; palpi yellowish brown; fore and mid coxae, trochanters, trochantellus and telotarsus brownish, remainder of fore and mid legs yellowish brown; hind coxa, trochanter and trochantellus blackish brown, femur reddish brown except infuscated basally and apically, tibia yellowish brown except infuscated basally and apically, tarsus blackish brown.

Variation. Pronotum granulose to granulose-punctate dorsally; propodeal area basalis trapezoid to rectangular; propodeal spiracle round to oval; first tergite 2.6–2.9× longer than width of postpetiole.

Distribution. China (Heilongjiang, Jilin, Zhejiang).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. anatolus Gupta & Maheshwary, 1977 , but differs from the latter by having mesopleuron granulose-punctate, vein 1cu-a distad of M&RS by 0.3 of its length, propodeal carinae stronger, metasoma entirely granulose, and tegula blackish brown.

Etymology. Name derived from “granum” (Latin for “seed”) and “alvus” (Latin for “metasoma”), because its metasoma is entirely granulose.
