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.

,

,

,

).
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.
