Figs. 31–32

Material examined. Holotype: female, Jilin, Tonghua, 1.VIII.1994, Lou Juxian, No 976691 ( ZJUH) . Paratype: female, Jilin, Tonghua , 1.VIII.1994, Lou Juxian, No976660 .

Description. Female ( Fig. 31 ) holotype. Body length 6.8 mm, fore wing length 4.5 mm.

Head. Antenna with at least 33 flagellomeres (apical segments missing); first flagellomere 1.1× longer than second flagellomere. Face ( Fig. 32E ) strongly granulose. Clypeus ( Fig. 32E ) granulose-punctate, slightly convex, apical margin arched. Malar space granulose, 0.6× basal width of mandible. Mandible with lamella. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 32F ) 2.1× ocello-ocular distance and 1.9× distance between median and lateral ocelli. Temple granulose, subpolished. Occipital carina gradually narrow dorsally.

Mesosoma. Pronotum granulose-punctate dorsally, trans-striate below. Mesoscutum ( Fig. 32G ) granulosepunctate, becoming rugose in notaulic area. Scutellum granulose with posterior rugose. Metanotum granulose. Mesopleuron ( Fig. 32B ) granulose-punctate, trans-striate below tegula, speculum smooth and shiny. Propodeum ( Fig. 32C ) with area basalis trapezoid; area superomedia granulose; area petiolaris trans-striate; area superomedia confluent with area petiolaris, moderately depressed medially; all carina moderately developed; propodeal spiracle small and round.

Wing. Fore wing ( Fig. 32A ) areolet present and with a short stalk emitting 2m-cu vein from its apical part. 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 acute (70°). Hind wing with nervellus intercepted above the middle.

Legs. Hind femur 4.1× longer than wide. Inner spur of hind tibia 0.6× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.

Metasoma. First metasomal segment ( Fig. 32H ) round in cross-section of basal 0.3, lateral carina and lateral groove almost absent. Postpetiole and second tergite finely granulose. Second tergite 0.75× as long as first tergite, 1.3× longer than its apical width; thyridium large, its distance from basal margin of tergite 0.8× its length. Third tergite slightly shorter than its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.7× longer than hind femur, ovipositor ( Fig. 32D ) gradually upcurved.

Colour. Black. Mandible except teeth, scape and pedicel black; palpi and tegula yellowish brown; fore leg from coxa on yellowish brown except telotarsus brown, coxa black; mid leg from trochantellus on yellowish brown except telotarsus brown, coxa black, trochanter and trochantellus blackish brown; hind coxa, trochanter and trochantellus black, femur reddish brown, tibia yellowish brown except basally and apically brown, tarsus brown with telotarsus darker; metasoma black.

Variation. Occipital carina evenly arched or gradually narrow dorsally; mesoscutum becoming rugose or not in notaulic area; hind wing with nervellus intercepted above the middle or at lower 0.4.

Distribution. China (Jilin).

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 apical margin arched, interocellar distance 2.1× ocellar-ocular distance, metapleuron granulose-punctate, nervellus broken above the middle, thyridium large, mandible except teeth black, and mid leg trochanter and trochantellus blackish brown.

Etymology. Name derived from “grandis” (Latin for “large”) and “alphus” (Latin for “spot”), because its thyridium is large as compared to other species in this genus.
