Abstract
Species of the tribe Rhotanini Muir (1918) (Hemiptera: Auchenorrhyncha: Derbidae) are found in the humid tropics of southern Asia, Australia, the Pacific and West Africa. In particular, many species are found in the rain forests of Borneo and New Guinea. This tribe has received little attention in the past and we provide a comprehensive taxonomic revision of its species. We recognize the following eight genera: Alara Distant, 1911 (=Mecynorhynchus Muir), 31 species, Dichotropis Muir, 1913, 9 species,Levu Kirkaldy, 1906, 34 species, Muiralevu Zelazny, 1981 (=Formolevu Yang & Wu, syn. nov.), 19 species, Rhotana Walker, 1857 {=Genestia Stal, = Decora Bierman), 72 species, Rhotanella Fennah, 1970, 8 species, Saccharodite Kirkaldy, 1907 (=Muiralyricen Metcalf, =Malpa Metcalf, = Genestiella Fennah), 108 species and Sumangala Distant, 1911, 13 species. Maps illustrating the distribution of these 8 genera and tables showing the distribution of each species are provided. A key to the genera is included. Where possible, species within each genus are grouped into species groups and keys are provided for the species within these groups. Keys are also given for the species of a genus found in a given country or larger island. The 116 previously known speciesof the tribe are reviewed and many are redescribed. We propose the following new combinations or new status: Rhotana biermani (Schmidt 1926) n. comb., Rhotana dammermani (Schmidt 1926) n. comb., Rhotana lalage (Fennah 1969) n. comb., Saccharoditepalauensis (Fennah 1956) n. comb., Saccharodite ponapeana (Fennah 1956) n. comb., Levu haedulus (Fennah 1956) new status, Levu lactineus (Fennah 1956) new status, Levupaganus (Fennah 1956) new status, Muiralevu exotivus (Yang & Wu 1993) n. comb, and Muiralevu quadramaculatus (Muir) rev. comb. We also describe the following new species.
