The genus is named in honour of C. R. Narayan Rao in recognition of his contribution to Indian batrachology.[3] The other root orchestes is based on an older genus name for frogs of the Philautus group, Orchestes Tschudi 1838.[5] Extensive exploration in the range of the genus in the Western Ghats of India suggests an under-estimation of the number of species in the genus.[6][7][8] A study of the diverse species of the genus show that the separate isolated massifs of the Western Ghats played a major role in the speciation and habitat specificity seen in the genus of bush frogs.[7]
