Figs. 21–22
Material examined. Holotype: female, Liaoning, Shenyang, VI–VII.1995, Lou Juxian, No 961003 (ZJUH). Paratype: female, Liaoning, Shenyang, VI–VII.1995, Lou Juxian, No961043.
Description. Female (Fig. 21) holotype. Body length 5.1 mm, fore wing length 4.3 mm.
Head. Antenna with at least 25 flagellomeres (apical segments missing); first flagellomere 1.25× longer than second flagellomere. Face (Fig. 22E) granulose. Clypeus (Fig. 22E) granulose with sparse punctures, slightly convex, apical margin slightly arched. Malar space granulose, 0.55× basal width of mandible. Mandible without lamella, upper tooth equal to the length of lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance (Fig. 22F) 1.2× ocello-ocular distance and 1.5× distance between median and lateral ocelli. Temple granulose, mat. Occipital carina evenly arched, reaching hypostomal carina at mandible base.
Mesosoma. Pronotum granulose with sparse punctures dorsally, mat, trans-striate below. Mesoscutum (Fig. 22G) granulose punctate. Scutellum granulose-punctate. Metanotum granulose. Mesopleuron (Fig. 22B) granulosepunctate, trans-striate below tegula, speculum smooth and shiny. Metapleuron (Fig. 22B) granulose. Propodeum (Fig. 22C) granulose; area basalis confluent with area superomedia; area superomedia confluent with area petiolaris; area petiolaris granulose-rugulose; all carina very weakly developed; propodeal spiracle small and oval.
Wing. Fore wing (Fig. 22A) areolet absent. Marginal cell short, distal part of surrounding vein 2.2× longer than proximal one. Vein 1cu-a opposite M&RS. External angles of second discal cell acute (65°). Hind wing with nervellus slightly inclivous, intercepted at lower 0.15.
Legs. Hind femur 5.3× 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. 22H) round in cross-section of basal 0.3, dorso-lateral carina and lateral groove absent. First tergite 2.6× longer than width of postpetiole. Second tergite 0.75× as long as first tergite, 1.0× as long as its apical width; thyridium round, its distance from basal margin of tergite equal to its diameter. Third tergite 0.8× as long as its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.0× longer than hind femur, ovipositor (Fig. 22D) gradually upcurved.
Colour. Black. Mandible except teeth, palpi and tegula, whitish yellow; scape and pedicel yellowish brown; fore and mid legs with coxa, trochanter and trochantellus whitish yellow, mid leg coxa basally weakly brown, remainder of fore and mid legs yellowish brown; hind leg coxa and trochanter black, trochantellus whitish-yellow, femur yellowish brown, tibia whitish yellow with apically infuscated, tarsus from basal 0.8 on brown, basal 0.8 yellowish brown; metasoma entirely black.
Variation. Interocellar distance 1.2–1.5× distance between median and lateral ocelli; propodeal lateral carina absent to very weak; hind femur 5.3–5.7× longer than wide.
Distribution. China (Liaoning).
Comparative diagnosis. This species is similar to C. assosae Kittel, 2016, but differs from the latter by having interocellar distance 1.2× ocello-ocular distance, propodeal area basalis confluent with area superomedia, area petiolaris granulose-rugulose, hind wing with nervellus slightly inclivous, fore and mid legs coxa whitish yellow, and hind trochanter blackish brown.
Etymology. Name derived from “confluus” (Latin for “confluent”), because its propodeal area basalis, area superomedia area and area petiolaris are confluent.
