Head. Antenna with 14 antennomeres, all antennomeres longer than wide ( Fig. 13A View FIGURE 13 ). First flagellomere 1.1 × as long as second flagellomere. First, second and penultimate flagellomeres 4.8, 4.6 and 2.4 × as long as wide. Maxillary palp with four segments ( Figs 13A, B View FIGURE 13 ), fourth segment 1.2 × as long as third segment. Face distinctly convex medially and laterally ( Fig. 13B View FIGURE 13 ), 1.5 × as wide as long, smooth, setose. Clypeus 2.4 × wider ventrally than medially high with convex posterior margin ( Fig. 13B View FIGURE 13 ). Malar suture distinct ( Fig. 13B View FIGURE 13 ). Length of malar space 1.2 × basal width of mandible. Mandible distinctly twisted ( Fig. 13B View FIGURE 13 ), inner tooth distinctly shorter than outer tooth. Frons smooth, convex medially, setose ( Fig. 13C View FIGURE 13 ). Vertex smooth, setose ( Fig. 13C View FIGURE 13 ). OOL: transverse diameter of posterior ocellus: POL= 2.8: 1.0: 1.2. Length of eye 1.4 × as long as temple in dorsal view.
Mesosoma. Mesosoma 1.4 × as long as high. Pronotum and propleuron smooth laterally ( Fig. 13D View FIGURE 13 ). Mesoscutum punctate in anterior half smooth posteriorly, setose, carinate postero-laterally ( Fig. 13E View FIGURE 13 ). Notauli only impressed anteriorly, faintly crenulated ( Fig. 13E View FIGURE 13 ). Scutellar sulcus represented only by a transverse groove, not crenulated ( Fig. 13E View FIGURE 13 ). Scutellum evenly setose, smooth ( Fig. 13E View FIGURE 13 ), with a pair of large pits medio-posteriorly separated by a carina, sides of scutellum irregularly sculptured ( Fig. 13F View FIGURE 13 ). Mesopleuron smooth, glabrous, setose ventrally ( Fig. 13D View FIGURE 13 ). Metapleuron with a deep small pit antero-dorsally, with deep shallow longitudinal depressed line, glabrous ( Fig. 13D View FIGURE 13 ). 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. 13F View FIGURE 13 ).
Wings. Fore wing: Vein r distinct, 0.3 × as long as 2RS ( Fig. 14C View FIGURE 14 ). R1 distinct, wide ( Fig. 14C View FIGURE 14 ). Vein (RS+M)b 0.6 × as long as 1m-cu. Vein 1-M 1.5 × as long as m-cu. Vein (RS+M)a 2.6 × (RS+M)b. Vein 1CUa thickened, 0.6 × as long as 1CUb ( Fig. 14C View FIGURE 14 ). Hind wing: Vein cu-a straight. Veins M+CU: 1M: 1r-m= 2.3: 2.7: 1.0.
Legs. Hind coxa smooth, setose ( Figs 13A View FIGURE 13 , 14A View FIGURE 14 ). Tarsal claws without basal lobe. Hind femur, tibia and basitarsus 4.2, 10.4 and 4.6 × as long as wide respectively.
Metasoma. First tergite smooth, widening medially, weakly narrowing apically, distinctly narrowing basally, 3.4 × as long as its maximum width ( Fig. 14B View FIGURE 14 ). Second tergite longitudinally striate, setose, medial length 0.7 × as long as third tergite ( Fig. 14B View FIGURE 14 ). Third tergite longitudinally striate, setose ( Fig. 14B View FIGURE 14 ). Ovipositor straight. Ovipositor sheath 0.1 × as long as fore wing, slightly narrowing apically with long setae apically ( Figs 14A, B View FIGURE 14 ).
Colour. Body reddish brown except face, clypeus, mandible, maxillary and labial palps, vertex laterally, tegula, legs except hind tarsus yellow.
Male. Unknown.
Etymology. The species is named after its brown body; “ yamu ” is brown the language of Adi indigenous people of Arunachal Pradesh.
Biology. Unknown.
Distribution. India (Arunachal Pradesh).
Comparative diagnosis. The new species is coming close to C. sii (Maetô, 1995) by the following characters, pterostigma brown, first flagellomere 1.1 × as long as second flagellomere and mesoscutum brownish. However, the new species differs from the latter in having the following differences; length of eye 1.4 × as long as temple in dorsal view (1.1 × in C. sii ), first flagellomere 4.8 × as long as wide (5.0–6.0 × in C. sii ), OOL 2.3 × POL (1.6 in C. sii ) and hind femur 4.2 × as long as wide (3.6–3.8 × in C. sii ).
