First, second and penultimate flagellomeres 4.8, 4.2 and 2.6 × as long as wide. Maxillary palp with four segments ( Figs 5B, D View FIGURE 5 ), fourth segment 1.4 × as long as third segment. Face distinctly convex medially ( Fig. 5B View FIGURE 5 ), 1.8× as wide as long, smooth, setose. Clypeus 1.5 × wider ventrally than medially high with convex posterior margin ( Fig. 5B View FIGURE 5 ). Malar suture distinct ( Figs 5B, D View FIGURE 5 ). Length of malar space 1.1 × basal width of mandible. Mandible distinctly twisted ( Fig. 5B View FIGURE 5 ), inner tooth distinctly shorter than outer tooth. Frons smooth, convex medially, setose laterally, glabrous medially ( Fig. 5C View FIGURE 5 ). Vertex smooth, glabrous medially, setose laterally ( Fig. 5C View FIGURE 5 ). OOL: transverse diameter of posterior ocellus: POL= 1.8: 1.0: 1.0. Length of eye 2.0 × as long as temple in dorsal view.

Mesosoma. Mesosoma 1.6 × as long as high. Pronotum and propleuron smooth laterally ( Fig. 5D View FIGURE 5 ). Mesoscutum punctate in anterior half smooth posteriorly, setose, without carinae laterally ( Fig. 5E View FIGURE 5 ). Notauli only impressed anteriorly, faintly crenulated ( Fig. 5E View FIGURE 5 ). Scutellar sulcus represented only by a transverse groove, not crenulated ( Fig. 5E View FIGURE 5 ). Scutellum evenly setose, smooth ( Fig. 5E View FIGURE 5 ), with a pair of large pits medio-posteriorly separated by less than diameter of a pit and rugose between large pits, sides of scutellum irregularly sculptured ( Fig. 5F View FIGURE 5 ). Mesopleuron smooth, glabrous, setose ventrally ( Fig. 5D View FIGURE 5 ). Metapleuron with a deep small pit antero-dorsally, with deep shallow longitudinal depressed line, glabrous ( Fig. 5D View FIGURE 5 ). Propodeum with a distinct and complete medio-longitudinal carina absent behind costula, dorsal part of midlongitudinal carina associated with irregular sculpture, sparsely setose, antero-lateral part with shallow declivity, postero-lateral part faintly crenulated, posterior part well differentiated from dorsal part, posterior transverse carina distinct ( Fig. 5F View FIGURE 5 ).

Wings. Fore wing: Vein r distinct, 0.2 × as long as 2RS ( Fig. 6D View FIGURE 6 ). R1 indistinct ( Fig. 6D View FIGURE 6 ). Vein (RS+M)b 0.7 × as long as 1m-cu. Vein 1-M 1.5 × as long as m-cu. Vein (RS+M)a 2.4 × (RS+M)b. Vein 1CUa thickened, 0.8 × as long as 1CUb ( Fig. 6D View FIGURE 6 ). Hind wing: Vein cu-a straight. Veins M+CU: 1M: 1r-m= 2.3: 3.2: 1.0.

Legs. Hind coxa smooth, setose ( Figs 5A View FIGURE 5 , 6A View FIGURE 6 ). Tarsal claws without basal lobe. Hind femur, tibia and basitarsus 3.2, 5.7 and 4.0 × as long as wide respectively.

Metasoma. First tergite smooth, widening medially, weakly narrowing apically, distinctly narrowing basally, 2.4 × as long as its maximum width ( Figs 6B, C View FIGURE 6 ). Second tergite longitudinally striate, setose, medial length 0.65 × as long as third tergite ( Figs 6B, C View FIGURE 6 ). Third tergite longitudinally striate, setose ( Fig. 6C View FIGURE 6 ). Ovipositor straight. Ovipositor sheath 0.04 × as long as fore wing, slightly narrowing apically with long setae apically ( Fig. 6A View FIGURE 6 ).

Colour. Body reddish brown except head, maxillary and labial palps, mesoscutum medially, scutellum, pterostigma, legs, metasoma except second tergite dorsally yellow.

Male. Unknown.

Etymology. The species is named after its yellow pterostigma; “ flavus ” is yellow in Latin.

Biology. Unknown.

Distribution. India (Karnataka).

Comparative diagnosis. The new species comes close to C. procarinator Ranjith & van Achterberg, 2018 , sharing the posterior pits of scutellum separated by 0.5 × diameter of pit. But the new species can be separated from C. procarinator by the following differences: transverse posterior carina of propodeum arched and close to an additional transverse carina (transverse posterior carina rounded medially and without additional transverse carina in C. procarinator ), shorter malar space than in C. procarinator ; lateral depressions of metanotum smooth (crenulate in C. procarinator ), first flagellomere 4.8 × as long as wide (4.1 × in C. procarinator ), hind basitarsus 4.0 × as long as wide (4.5 × in C. procarinator ) and OOL 1.8 × POL (2.2 × in C. procarinator ). Based on the character of midlongitudinal carina of propodeum bifurcated posteriorly, the new species comes close to C. tihamica Ghramh & Ahmad, 2019 described from Saudi Arabia. However, the new species can be distinguished from the latter in having mesoscutum yellowish (blackish brown in C. tihamica), dorsal length of eye 2.0 × as long as temple (1.5 × in C. tihamica), scutellar sulcus without crenulae (with crenulae in C. tihamica), hind tibia 5.7 × as long as wide (7.0 × in C. tihamica) and first metasomal tergite 2.4 × as long as maximum width (4.0 × in C. tihamica).
