Figs. 73–74

Material examined. Holotype: female, Shanxi, Taigu, 20.I.1984, Zeng Kecheng , host: Telphusa chloroderces, No 840930 ( ZJUH) . Paratype: 1 female, Shanxi, Taigu, 3.VIII.1983, Zeng Kecheng , host: Adoxophyes orana, No 850112 .

Description. Female ( Fig. 73 ) holotype. Body length 5.3 mm, fore wing length 3.8 mm.

Head. Antenna with at least 25 flagellomeres (apical segments missing); first flagellomere 1.3× longer than second flagellomere. Face ( Fig. 74E ) granulose. Clypeus ( Fig. 74E ) granulose and mat medially, with minute punctures, slightly convex, apical margin truncate, slightly thick medially. Malar space granulose, 0.6× basal width of mandible. Mandible without lamella, upper tooth equal to lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 74F ) 1.7× ocello-ocular distance and 1.5× distance between median and lateral ocelli. Temple granulose, subpolished, not immediately receding after eye. Occipital carina evenly arched, reaching hypostomal carina at mandible base.

Mesosoma. Pronotum granulose-punctate dorsally, subpolished, trans-striate below. Mesoscutum ( Fig. 74G ) granulose punctate. Scutellum punctate. Metanotum finely granulose. Mesopleuron ( Fig. 74B ) punctate, punctures denser ventrally, trans-striate below tegula, speculum smooth and shiny. Metapleuron ( Fig. 74B ) punctate, punctures sparser than that on mesopleuron. Propodeum ( Fig. 74C ) with area basalis triangular; area superomedia nearly smooth and shiny, weakly granulose; area petiolaris strongly rugose; area superomedia confluent with area petiolaris, not depressed; all carina distinctly developed; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 74A ) areolet present and with a short stalk emitting 2m-cu vein from its apical part. Marginal cell short, distal part of surrounding vein 1.6× longer than proximal one. Vein 1cu-a opposite M&RS. External angles of second discal cell acute (75°). 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 0.5× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.

Metasoma. First metasomal segment ( Fig. 74H ) round in cross-section of basal 0.3, without dorso-lateral carina and lateral groove. First tergite 2.4× longer than width of postpetiole. Postpetiole and second tergite granulose, mat. Second tergite 0.6× as long as first tergite, equal to its apical width; thyridium round, its distance from basal margin of tergite equal to its diameter. Third tergite 0.6× as long as its apical width. Sixth and seventh tergites without emarginations. Ovipositor sheath approx. 1.3× longer than hind femur, ovipositor ( Fig. 74D ) gradually upcurved.

Colour. Black. Mandible except teeth, palpi and tegula, yellowish brown; scape and pedicel blackish brown; pterostigma whitish basally; fore coxa, trochanter, trochantellus and telotarsus brown, remainder of fore leg yellowish brown; mid coxa, trochanter, base of trochantellus, base of femur, tibia ventrally and telotarsus brown, tibia dorsally whitish yellow, remainder of mid leg yellowish brown; hind coxa, trochanter, trochantellus and base of femur, brownish, tibia clearly banded with base and apex blackish brown, whitish yellow medially, tarsus blackish brown; metasoma black with apical tergites somewhat blackish brown.

Distribution. China (Shanxi).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. phthorimaeae ( Cushman, 1915) , but differs from the latter by having mesosoma subpolished, hind femur yellowish brown except brownish basally, metasoma entirely black with apical tergites somewhat blackish brown, and area superomedia not as wide as area petiolaris.

Etymology. Name derived from the name of type locality of species.
