Variation. The paratype female varies as follows; lateral lobes of mesoscutum and scutellum yellowish brown.
Male. Unknown.
Distribution. Oriental ( India and Thailand).
Biology. Unknown.
Etymology. APR dedicates the species to Ms. Dhithya Venkateswaran for her unwavering support and encouragements.
Comparative diagnosis. The new species can be distinguished from the type species by the differences mentioned in the key. Apart from the differences cited in the key the new species differs from C. albocoxalis by the following characters; eye 2.5 × as long as temple in dorsal view (vs 3.3 × in C. albocoxalis ), third antennomere 2.6 × as long as wide (vs 1.6 × in C. albocoxalis ), and hind femur 3.7 × as long as wide (vs 3.4 × in C. albocoxalis ).
