Material examined. Holotype: female, Yunnan, Anning, 18.VII.1988, Chen Xuexin, No 881522 ( ZJUH) . Paratype: 1 female, Yunnan Lijiang, 18.VIII.2003, Li Yanjing, No 20046116 .

Description. Female ( Fig. 69 ) holotype. Body length 8.0 mm, fore wing length 5.0 mm.

Head. Antenna with 38 flagellomeres; first flagellomere 1.3× longer than second flagellomere. Face ( Fig. 70E ) rugose-punctate. Clypeus ( Fig. 70E ) granulose-punctate, convex, apical margin arched. Malar space granulose, 0.6× basal width of mandible. Mandible with lamella, upper tooth equal to the length of lower tooth. Frons granulose, median carina present. Vertex granulose. Interocellar distance ( Fig. 70F ) 1.8× ocello-ocular distance and 2.5× distance between median and lateral ocelli. Temple granulose, mat, not swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina at mandible base.

Mesosoma. Pronotum punctate dorsally, subpolished, trans-striate below. Mesoscutum ( Fig. 70G ) granulosepunctate, rugose in notaulic region. Scutellum granulose-punctate anteriorly, rugose posteriorly. Metanotum rugosepunctate. Mesopleuron ( Fig. 70B ) punctate, trans-striate below tegula, speculum smooth and shiny. Metapleuron ( Fig. 70B ) granulose-punctate, rugose ventrally. Propodeum ( Fig. 70C ) with area basalis trapezoid; area superomedia trans-rugose; area petiolaris trans-striate; area superomedia confluent with area petiolaris, with a deep groove medially; latero-longitudinal carina absent; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 70A ) areolet present and with a moderate 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 (60°). Hind wing with nervellus inclivous, intercepted at lower 0.1.

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. 70H ) round in cross-section of basal 0.3, dorso-lateral carina weakly present. without lateral groove. First tergite 2.7× longer than width of postpetiole. Second tergite 0.7× as long as first tergite, 1.5× longer than its apical width; thyridium round, its distance from basal margin of tergite 2.0× its diameter. Third tergite 1.3× longer than its width. Metasoma from third tergite on strongly compressed. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.6× longer than hind femur, ovipositor ( Fig. 70D ) gradually upcurved.

Colour. Black. Mandible medially yellowish brown; scape and pedicel brown; tegula yellowish brown; fore leg entirely yellowish brown except coxa brown; mid leg yellowish brown except coxa and telotarsus brown; hind coxa blackish brown, trochanter, trochantellus, tibia basally and apically, tarsus except basal tarsomere 0.8 brown, femur reddish brown, tibia medially and basal tarsomere 0.8 yellowish brown; metasoma entirely black.

Variation. Propodeal median groove moderately deep to strongly deep, lateral carina absent or present; second metasomal tergite 1.5–1.8× longer than its apical width.

Distribution. China (Yunnan).

Comparative diagnosis. This species is similar to C. strigatus sp. nov., but differs from the latter by having mesopleuron with striations not extending to prepectal carina, lateral carina of propodeum absent, dorso-lateral carina of first metasomal segment present and metasoma entirely black.

Etymology. Name derived from “pseudo” (Greek for “pseudo”), and the specific name “ strigatus ”, because of its similarity to C. strigatus sp. nov.
