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.
