Revision of the cicadas of the Platylomia spinosa group (Homoptera : Cicadidae)

The Platylomia spinosa group is recognized for a monophyletic group of nine species of cicadas from the Oriental Region. The group is revised and the genus Champaka a is synonymized with the genus Platylomia. Champaka celeben sis Distant, 1905, C. viridimaculata (Distant, 1889), and Dundubia aerata D istant, 1888, are transferred to Platylomia. The other species belonging to the P. spinosa group are P. spinosa (Fabricius, 1787), P. abdulla (Distant , 1881), P. meyeri (Distant, 1883), P. nigra (Distant, 1888), P. virescens Distant, 1905, and P. wallacei. n.sp. All species are found in the Indo-Mal aysian Archipelago and the Philippines. Four species are synonymized: P. al bomaculata (Distant, 1905) with P. nigra, P. distanti (Moulton, 1911) with P. abdulla, P. maculata Liu, 1940 with P. spinosa, and P. majuscula (Distan t, 1888) with P. meyeri. Lectotypes are designated for the following specie s: Cosmopsaltria abdulla, C. nigra, Dundubia majuscula, Platylomia albomacu lata, P. virescens, and Tettigonia spinosa. A key to the males and known fe males is presented and the distributions of the species are discussed.
