A new genus and five new species Ariasa maryannae n. sp., Ariasa russelli n. sp., Guyalna jamesi n. sp., Guyalna maxineae n. sp., and Malloryalna susanae n. gen., n. sp. are described. Cicada kirkaldyi Metcalf, 1963 and its synonyms (C. obtusa Uhler, 1903 and C. brasiliensis Kirkaldy, 1909) are transferred to the genus Fidicinoides Boulard & Martinelli, 1996 to become Fidicinoides kirkaldyi (Metcalf, 1963) n. comb. Cicada egregia Uhler, 1903 is transferred to the genus Ariasa Distant, 1905 to become Ariasa egregia (Uhler, 1903) n. comb. Dorisiana bicolor (Olivier, 1790) is transferred to the genus Guyalna Boulard and Martinelli, 1996 to become Guyalna bicolor (Olivier, 1790) n. comb. Fidicinoides passerculus (Walker, 1850) n. syn., Fidicinoides spinicosta (Walker, 1850) n. syn. and Cicada lacrines Walker, 1850 n. syn. are shown to be junior synonyms of Guyalna bicolor n. comb. Fidicina parvula Jacobi, 1904 is transferred to the genus Guyalna Boulard & Martinelli, 1996 to become Guyalna parvula (Jacobi, 1904) n. comb. Previous records of Fidicinoides passerculus (Walker, 1850) and Carineta illustris Distant, 1905 from French Guiana are shown to be Dorisiana bicolor (Olivier, 1790) and Carineta cearana Distant, 1906, respectively, and are removed from the cicada fauna of French Guiana; this is the first record of C. cearana for French Guiana. The cicada fauna of French Guiana is hereby increased to 62 species in 17 genera.
