Scutellar sulcus wide divided by seven carinae (Fig. 1D). Scutellum smooth, setose (Fig. 1D). Mesopleuron smooth, sparsely setose with a pit medio-posteriorly (Fig. 1E). Precoxal sulcus shallow not crenulated (Fig. 1E). Metapleuron smooth, setose (Fig. 1E). Medial area of metanotum with short midlongitudinal carina anteriorly (Fig. 1F). Propodeum smooth, setose with complete, raised midlongitudinal carina, posterior and lateral part of propodeum depressed in dorsal view (Fig. 1F), lateral area of propodeum raised in lateral view (Fig. 1E).
Wings. Fore wing: angle between vein C+SC+R and 1RS 60°. Ratio of length of veins r-rs: 3RSa: 3RSb= 1.0: 2.7: 6.0 and 2RS: 3RSa: rs-m= 1.5: 1.1: 1.0. Second submarginal cell narrowing apically (Fig. 2E). Vein 1cu-a interstitial (Fig. 2E). Hind wing: vein R longitudinal.

Male. Unknown.
Distribution. India (Kerala).
Host. Unknown.
Etymology. The name refers to the distribution realm of the species, Oriental region.
Comments. Apart from the differences cited in the key, C. orientalis sp. nov. differs from the only member of the genus, C. danielssoni in having scape yellow (vs brown), antenna with 40 segments (vs 35 segments), first flagellomere 1.23× as long as wide (vs 2.30× as long as wide), face 2.20× as wide as long (vs 1.90× as wide as long), frons with a complete deep midlongitudinal groove (vs with a short mid longitudinal groove), propodeum raised postero-laterally in lateral view (vs propodeum not raised postero-laterally in lateral view), hind coxa smooth (vs punctulate), first metasomal tergite 1.30× as long as wide apically (vs 0.80× as long as wide apically), hind tarsus brown (vs dark yellow).
