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.
