Description. Female ( Fig. 13 ) holotype. Body length 6.7 mm, fore wing length 4.5 mm.

Head. Antenna with 34 flagellomeres; first flagellomere 1.3× longer than second flagellomere. Face ( Fig. 14E ) granulose, weak laterally. Clypeus ( Fig. 14E ) granulose, slightly convex, apical margin blunt, almost truncated. Malar space shiny, 0.3× basal width of mandible. Mandible with a weak lamella, upper tooth longer than the length of lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 14F ) 1.0× ocelloocular distance and 2.0× 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 dorsally, mat, trans-striate below. Mesoscutum ( Fig. 14G ) granulose. Scutellum and metanotum granulose. Mesopleuron ( Fig. 14B ) granulose, trans-striate below tegula, speculum smooth and shiny, rugose above mesopleural fovea. Metapleuron ( Fig. 14B ) granulose. Propodeum ( Fig. 14C ) with area basalis trapezoid; area superomedia granulose-rugulose, subpolished; area petiolaris trans-striate; area superomedia confluent with area petiolaris, slightly depressed; latero-longitudinal carina weakly developed; propodeal spiracle small and nearly round.

Wing. Fore wing ( Fig. 14A ) 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 slightly inclivous, 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.

Metasoma. First metasomal segment ( Fig. 14H ) round in cross-section of basal 0.3, dorso-lateral carina and lateral groove present. First tergite 3.7× longer than width of postpetiole. Second tergite 0.7× as long as first tergite, 1.8× longer than its apical width; thyridium oval, its distance from basal margin of tergite 2.0× its diameter. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 0.9× longer than hind femur, ovipositor ( Fig. 14D ) gradually upcurved.

Colour. Black. Mandible except teeth and tegula yellowish brown; palpi yellow; scape and pedicel blackish brown; fore leg yellowish brown except coxa brown; mid leg with coxa, trochanter and trochantellus externally, basal 0.7 of femur and telotarsus blackish brown, remainder of mid leg yellowish brown; hind leg with extreme base of femur yellowish brown, tibia medially whitish yellow, remainder of hind leg black; metasoma entirely black.

Variation. Antenna with 33–36 flagellomeres; interocellar distance 1.3–2.0× distance between median and lateral ocelli; fore wing areolet with stalk short to moderately long; ovipositor sheath approx. 0.9–1.2× longer than hind femur; mid femur entirely yellowish brown or black basally.

Male. Essentially similar to female except propodeal carina stronger, mid leg whitish yellow except femur basal-ventrally and coxa brown.

Distribution. China (Guizhou, Sichuan, Yunnan, Zhejiang).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. maximalus Gupta & Maheshwary, 1977 , but differs from the latter by having malar space 0.3× basal width of mandible, medio-longitudinal carina moderately developed, areolet equal to the length of stalk, nervellus intercepted at lower 0.2, and first metasomal segment with a strong lateral carina.

Etymology. Name derived from “artus” (Latin for “narrow”) and “vultus” (Latin for “face”), refer to its comparatively narrow face.
