The cicada genus Rustia Stål, 1866 is redescribed. The synonymy of Gudaba Distant, 1906 n. syn. is proposed reassigning the four species of that genus to become Rustia apicata (Distant, 1906) n. comb., Rustia longicauda (Lei, 1996) n. comb., Rustia maculata (Distant, 1912) n. comb., and Rustia marginata (Distant, 1897) n. comb. Two new species, Rustia minuta n. sp. and Rustia kodagura n. sp. that were found during our Indian cicada surveys in the Western Ghats are described. A key for the known species of the genus is provided.
