Contributions to the Study of the World Macropsini (Rhynchota: Homoptera: Cicadellidae)

The generic classification of the Macropsini is reviewed, and five new genera and four new subgenera are erected:Macropsellan. gen.,Macropsis(Neomacropsis) n. subgen,M. (Parapediopsis) n. subgen.,Pedionisn. gen.,P. (Thyia) n. subgen.,Pediopsoides(Celopsis) n. subgen.;Reticopsisn. gen.,Toropsisn. gen., andVaricopsellan. gen.. The following genus-group names are considered to be subgenera:MacropsidiusRibaut as a subgenus ofMacropsisLewis;NanopsisFreytag,KiamoncopsisLinnavuori andSispocnisAnufriev as subgenera ofPediopsoidesMatsumura;ParasitadesSingh-Pruthi as a subgenus ofOncopsisBurmeister.AsmaropsisLinnavuori is synonymized withHephathusRibaut,TsavopsisLinnavuori is synonymized withMacropsis(s.s.) Lewis, andZinnecaAmyot & Serville is synonymized withOncopsisBurm. (s.s.). Three hundred and seventy-three macropsine species (including 59 unnamed species) are placed generically, with 73 new combinations. Twelve new species are described:Macropsella complicata(New Guinea),Macropsis citronella(Australia),M.gagnei(New Guinea),M.gressitti(New Guinea),Oncopsis enopis(Nepal),O.nepalensis(Nepal),O.tortosa(Nepal),Pedionis astrala(Philippines),P.contrasta(Hong Kong),P.venosa(Japan),Pediopsis femorata(Formosa),Varicopsella obtusa(Borneo). An index is provided to the 436 available names in the Macropsini, including four unplaced species from the Ethiopian region and 21 from the Australian region. Macropsine types in the B.P. Bishop Museum, Honolulu, the British Museum (Natural History), London, Hokkaido University, Sapporo, Japan, and the U.S. National Museum, Washington are illustrated and lectotypes are designated for Kirkaldy and Matsumura species. A neotype in the Canadian National Collection is designated forZinneca flavidorsumAmyot & Serville.
