Figs. 49–50

Material examined. Holotype: female, Guizhou, Guiyang , 15.X.1983, He Junhua, No834559 ( ZJUH).

Description. Female ( Fig. 49 ) holotype. Body length 5.2 mm, fore wing length 4.4 mm.

Head. Antenna with 30 flagellomeres; first flagellomere 1.4× longer than second flagellomere. Face ( Fig. 50E ) granulose-punctate. Clypeus ( Fig. 50E ) granulose-punctate, slightly convex, apical margin slightly arched, thick medially. Malar space granulose, 0.6× basal width of mandible. Mandible without lamella, upper tooth equal to the length of lower tooth. Frons granulose, median carina present. Vertex granulose. Interocellar distance ( Fig. 50F ) 1.2× ocello-ocular distance and 2.0× distance between median and lateral ocelli. Temple granulose, subpolished, not swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina slightly above mandible base.

Mesosoma. Pronotum granulose-punctate dorsally, subpolished, trans-striate below. Mesoscutum ( Fig. 50G ) granulose punctate. Scutellum punctate and rugose posteriorly. Metanotum rugose-punctate. Mesopleuron ( Fig. 50B ) punctate, trans-striate below tegula, speculum smooth and shiny. Metapleuron ( Fig. 50B ) granulose. Propodeum ( Fig. 50C ) granulose; area basalis triangular, long and narrow; area superomedia granulose; area petiolaris rugose; area superomedia confluent with area petiolaris, not depressed; all carina strongly developed; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 50A ) areolet present and with a short 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 slightly distad of M&RS. External angles of second discal cell acute (70°). Hind wing with nervellus inclivous, intercepted at lower 0.15.

Legs. Hind femur 5.0× longer than wide. Inner spur of hind tibia 0.5× as long as first tarsomere of hind tarsus. Tarsal claws with indistinct teeth basally.

Metasoma. Mat. First metasomal segment ( Fig. 50H ) round in cross-section of basal 0.3, dorso-lateral carina and lateral groove weakly present. First tergite 2.7× longer than width of postpetiole. Second tergite 0.6× as long as first tergite, 0.8× 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 medially. Ovipositor sheath 1.5× longer than hind femur, ovipositor ( Fig. 50D ) gradually upcurved.

Colour. Black. Mandible medially and palpi yellowish brown; mandible basally black; tegula yellow; scape and pedicel blackish brown; fore and mid legs yellowish brown except coxa and telotarsus blackish; hind leg with coxa, trochanter and trochantellus basally blackish brown, tibia apically infuscated, tarsus from basal tarsomere 0.8 on brown, remainder of hind leg yellowish brown; metasoma black except second tergite laterally yellowish brown.

Distribution. China (Guizhou).

Comparative diagnosis. This species is similar to C. liuae sp. nov., but differs from the latter by having first flagellomere 1.4× longer than second flagellomere, clypeus granulose-punctate, frons with median carina present, area petiolaris rugose, nervellus intercepted at lower 0.15, tarsal claws with indistinct teeth basally, and the colour of metasoma different.

Etymology. Name derived from “medius” (Latin for “middle”) and “carina” (Latin for “carina”), because its frons has a median carina.
