Etymology. This species is named after a legendary bird ‘Chakora’ in Hindu mythology believed to reside on moonbeams. The name is treated as a noun in apposition.

Diagnosis. B. chakora   sp. n. is closer to B. ciprianii   sp. n. but differs from it by the combination of the following character states; in B. chakora   sp. n. the transverse carinae on dorsal mesopleuron extend below the dorsal level of metapleuron and the dorsal level of posterior metapleural suture is level with antero-lateral margin of T2; whereas in B. ciprianii   sp. n. the transverse carinae on dorsal mesopleuron terminate much above the dorsal level of metapleuron and the dorsal level of posterior metapleural suture ventral to the level of antero-lateral margin of T2.
