Figs. 59–60
Material examined. Holotype: female, Zhejiang, Xitianmushan, 3.VII.2000, Li Weidi, No 200104197 (ZJUH).
Description. Female (Fig. 59) holotype. Body length 4.2 mm, fore wing length 2.7 mm.
Head. Antenna with 25 flagellomeres; first flagellomere 1.25× longer than second flagellomere. Face (Fig. 60E) granulose. Clypeus (Fig. 60E) granulose, mat, slightly convex, apical margin slightly arched, thick medially. Malar space smooth, 0.6× 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. 60F) equal to ocello-ocular distance and 1.5× distance between median and lateral ocelli. Temple granulose, subpolished, not swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina at mandible base.
Mesosoma. Pronotum granulose with sparse punctures dorsally, mat, trans-striate below. Mesoscutum (Fig. 60G) granulose, rugose in notaulic area anteriorly. Scutellum and metanotum granulose. Mesopleuron (Fig. 60B) granulose with sparse punctures, trans-striate below tegula, speculum smooth and shiny. Metapleuron granulose. Propodeum (Fig. 60C) granulose; area basalis triangular; area superomedia granulose, long and narrow; area petiolaris rugulose-granulose; area superomedia area confluent with area petiolaris, not depressed; medio-longitudinal carina and latero-longitudinal carina weak, medio-longitudinal carina becoming strong apically; propodeal spiracle small and oval.
Wing. Fore wing (Fig. 60A) 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 (70°). Hind wing with nervellus vertical, intercepted at lower 0.2.
Legs. Hind femur 4.9× longer than wide. Inner spur of hind tibia 0.5× as long as first tarsomere of hind tarsus. Tarsal claws pectinate basally.
Metasoma. First metasomal segment (Fig. 60H) round in cross-section of basal 0.3, dorso-lateral carina present, without lateral groove. First tergite 2.8× longer than width of postpetiole. Postpetiole and second tergite granulose. Second tergite 0.7× as long as first tergite, 1.6× longer than its apical width; thyridium round, its distance from basal margin of tergite 1.5× its diameter. Third tergite 1.4× longer than its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.4× longer than hind femur, ovipositor (Fig. 60D) gradually upcurved.
Colour. Black. Mandible except teeth, palpi, tegula, fore and mid trochanters and trochantellus, and hind trochantellus, yellow; scape and pedicel blackish brown; fore and mid legs with coxae basally and telotarsus brown, remainder of fore and mid legs yellowish brown; hind leg with coxa black, trochanter basally, femur, tibia subbasally and apically, tarsus from basal 0.7 on blackish brown, remainder of hind leg yellowish brown; metasoma from third tergites on yellowish brown laterally, remainder of metasoma black.
Distribution. China (Zhejiang).
Comparative diagnosis. This species is similar to C. parassosae sp. nov., but differs from the latter by having clypeus granulose, area petiolaris rugulose-granulose, fore wing areolet with a moderately sized stalk, nervellus vertical, third metasomal tergite 1.4× longer than its apical width, and hind femur blackish brown.
Etymology. Name derived from “perpendicularis” (Latin for “upright”), because its hind wing with nervellus vertical.
