Figs. 5–6 Material examined. Holotype : female, Gansu , Zhenyuanxian , VII.1981 , Cao Wei , No 815326 ( ZJUH ) . Paratype : 1 female , Heilongjiang , Jingpohu , 26.VII.1995 , Lou Juxian , No 962390 . Description. Female ( Fig. 5 ) holotype . Body length 6.6 mm , fore wing length 5.2 mm . Head. Antenna with 35 flagellomeres; first flagellomere 1.3× longer than second flagellomere. Face ( Fig. 6D ) granulose-punctate to punctate. Clypeus ( Fig. 6D ) punctate, slightly convex, apical margin arched. Malar space granulose-punctate, 0.7× basal width of mandible. Mandible with a weak lamella, upper tooth equal to the length of lower tooth. Frons rugose-punctate, median carina absent. Vertex granulose-punctate. Interocellar distance ( Fig. 6E ) 1.7× ocello-ocular distance and 1.8× distance between median and lateral ocelli. Temple granulose, mat. Occipital carina evenly arched, reaching hypostomal carina slightly at mandible base. Mesosoma. Pronotum granulose-punctate dorsally, subpolished, trans-striate below. Mesoscutum ( Fig. 6F ) granulose-punctate. Scutellum punctate and rugose posteriorly. Metanotum rugose-punctate. Mesopleuron ( Fig. 6B ) punctate, trans-striate below tegula, speculum smooth and shiny. Metapleuron ( Fig. 6B ) punctate, punctures smaller than that on mesopleuron. Propodeum ( Fig. 6C ) with area basalis trapezoid; area superomedia granulose, with sparse punctures; area petiolaris rugulose-punctate; area superomedia confluent with area petiolaris, not depressed; all carina developed; propodeal spiracle small and oval.

A , fore wing; B , mesopleuron; C , propodeum; D , head, anterior view; E , head, dorsal view; F , mesoscutum; G , first metasomal segment. Wing. Fore wing ( Fig. 6A ) areolet present and with a short stalk emitting 2m-cu vein from its apical part. Marginal cell short, distal part of surrounding vein 1.9× 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 0.4 of its length. Legs. Hind femur 4.0× longer than wide. Inner spur of hind tibia 0.5× as long as first tarsomere of hind tarsus. Tarsal claws pectinate. Metasoma. Mat. First metasomal segment ( Fig. 6G ) round in cross-section of basal 0.3, dorso-lateral carina and lateral groove absent. First tergite 2.5× longer than width of postpetiole. Second tergite 0.6× as long as first tergite, 0.9× its apical width; thyridium round, its distance from basal margin of tergite equal to its diameter. Third tergite 0.7× as long as its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.1× longer than hind femur, ovipositor gradually upcurved. Colour. Black. Mandible medially and palpi yellowish brown; antenna, scape and pedicel brown; tegula yellow; fore leg yellowish brown with coxa black and telotarsus brown; mid leg yellowish brown with coxa and telotarsus black, trochanter brown; hind leg with coxa and trochanter black, trochantellus basally, tibia subbasally and apically, tarsus except basal tarsomere 0.8 brown, remainder of hind leg yellowish brown; metasoma black except postpetiole apically, second tergite apically and third segment basal-laterally brown. Variation. Antenna with 35–39 flagellomeres; hind wing with nervellus intercepted at lower 0.2–0.4; second and third metasomal tergites yellowish brown. Distribution. China ( Gansu , Heilongjiang ). Comparative diagnosis. This species is similar to C. monochroma sp. nov. , but differs from the latter by having malar space 0.7× basal width of mandible, frons rugose-punctate, propodeal area petiolaris rugulose-punctate, first metasomal segment without dorso-lateral carina and lateral groove, ovipositor sheath approx. 1.1× longer than hind femur, hind tibia subbasally and apically brown, second metasomal tergite apically, and third metasomal tergite basal-laterally brown. Etymology. Name derived from “adustus” (Latin for “brown”) and “antenna” (Latin for “antenna”), because of its antenna brown.
