New genera and species of the tribe Taphurini (Hemiptera, Cicadidae) from Sundaland

Three new genera and five species of Taphurini from Sundaland (Malayan Peninsula, Sumatra, Borneo and Java) are described: Sundabroma including S. bimaculata sp. n. from Borneo and S. suffusca sp. n. from the Malayan Peninsula, Allobroma including A. kedenburgi (Breddin, 1905) comb. n. from Borneo and Banguey Island and A. portegiesi sp. n. from West Malaysia and southern Thailand, and Unduncus including U. connexa (Distant, 1910) comb. n. from Borneo. The taxonomic position of the new genera is discussed. A new genus concept is proposed for Lemuriana Distant, 1905 that now includes two species, L. apicalis (Germar, 1830) from India and Nepal, and L. cambodiana Lee 2010 from Cambodia. Lemuriana chandaea Moulton, 1911 from Borneo is synonymized with Allobroma kedenburgi from Banguey Island. Abroma tahanensis Moulton, 1923 from the Malayan Peninsula is transferred to the genus Muda Distant, 1897 in the tribe Chlorocystini. The occurrence in Sundaland of Abroma maculicollis (Guérin Méneville, 1838), described from Bengal, proved to be unlikely. The species of Taphurini known from South-East Asia but not recorded from Sundaland have been checked to be sure that these species are not identical to new species described here.
