Description. Female (Fig. 63) holotype. Body length 5.3 mm, fore wing length 3.7 mm.

Head. Antenna with 32 flagellomeres; first flagellomere 1.05× longer than second flagellomere. Face (Fig. 64E) granulose. Clypeus (Fig. 64E) finely granulose, slightly convex, apical margin arched, blunt. Face and clypeus combined equal to minimum width of face. Malar space granulose, 0.6× basal width of mandible. Mandible with a weak lamella, upper tooth equal to the length of lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance (Fig. 64F) 1.0× ocello-ocular distance and 1.4× 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 granulose-punctate dorsally, mat, trans-striate below. Mesoscutum (Fig. 64G) granulose, rugulose-punctate on notaulic region. Scutellum and metanotum granulose. Mesopleuron (Fig. 64B) granulose, trans-striate below tegula, speculum smooth and shiny, rugulose above mesopleural fovea. Metapleuron (Fig. 64B) granulose. Propodeum (Fig. 64C) with area basalis trapezoid; area superomedia area granulose; area petiolaris trans-striate; area superomedia confluent with area petiolaris, slightly depressed; medio-longitudinal carina very weakly developed under costula, strongly developed apically; latero-longitudinal carina strongly developed; propodeal spiracle small and round.

Wing. Fore wing (Fig. 64A) areolet present and with a very short stalk, emitting 2m-cu vein from its basal 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 inclivous, intercepted at lower 0.3.

Legs. Hind femur 5.0× longer than wide. Inner spur of hind tibia 0.54× as long as first tarsomere of hind tarsus. Tarsal claws pectinate, its teeth weak.

Metasoma. First metasomal segment (Fig. 64H) round in cross-section of basal 0.3, with dorso-lateral carina and without lateral groove. First tergite 3.0× longer than width of postpetiole. Postpetiole and second tergite granulose, finely granulose on subsequent tergites. Second tergite 0.75× as long as first tergite, 1.5× longer than its apical width; thyridium round, its distance from basal margin of tergite 2.3× its diameter. Third tergite 0.9× as long as its apical width. Sixth and seventh tergites without emarginations. Ovipositor sheath approx. 1.3× longer than hind femur, ovipositor (Fig. 64D) gradually upcurved.

Colour. Black. Mandible except teeth and tegula yellowish brown; palpi yellow; scape and pedicel brown; fore leg yellowish brown except coxa basally brown; mid leg yellowish brown except coxa basally and telotarsus brown; hind leg with coxa, trochanter, extreme apical of femur, tibia basally and apically, brown, remainder of hind leg yellowish brown; third and fourth metasomal tergites basal-laterally blackish brown, subsequent tergites laterally yellowish brown, remainder of metasoma black.

Variation. Antenna with 29–32 flagellomeres; first flagellomere 1.05–1.2× longer than second flagellomere; malar space 0.5–0.6× basal width of mandible; interocellar distance 0.9–1.0× ocello-ocular distance; hind wing with nervellus intercepted at lower 0.2–0.4; first tergite 2.8–3.1× longer than width of postpetiole; thyridium separated from basal margin of tergite 1.8–2.3× its diameter; ovipositor sheath 1.3–1.5× longer than hind femur.

Distribution. China (Guangdong, Shaanxi, Zhejiang).

Comparative diagnosis. This species is similar to C. grandicella sp. nov., but differs from the latter by having first flagellomere 1.0–1.1× longer than second flagellomere, rugulose-punctate on notaulic region, medio-longitudinal carina strong apically, latero-longitudinal carina strongly developed, fore wing areolet emitting 2m-cu vein from its basal part, and hind femur yellowish brown.

Etymology. Name derived from “protenus” (Latin for “before”), because its fore wing areolet is emitting 2m-cu vein from its basal part.
