Revision of the Macropsini and Neopsini of the New-World (Rhynchota: Homoptera: Cicadellidae), With Notes on Intersex Morphology

The Neopsini encompasses two genera, both exclusively Neotropical:NeopsisOman (5 species) andNollian. gen. (2 species).Neopsis amazonican. sp.,Neopsis tumidifronsn. sp.,Neopsis magnan. sp. (Brazil), andNollia rustican. sp. (Chile) are described, and the genera and species of the Neopsini are keyed.The New-World Macropsini encompasses five genera:PediopsisBurmeister (1 species),PediopsoidesMatsumura (2 species),ReticopsisHamilton (2 species),MacropsisLewis (55 species), andOncopsisBurmeister (36 species). Biological and morphological data are used to define the species in this taxonomically difficult tribe, with the result that 45 new species are described:Macropsis acapulco,M.dimorpha,M.igniscutellata,M.mexicana,M.oncopsimilis, andM.zebrafrom Mexico;Macropsis aureocephala,M.californiensis,M.ferrax,M.inversalis,M.palustris,M.pulchra,Oncopsis arizona,O.aureostria, andReticopsis udrobatesfrom southern California and Arizona;Oncopsis insignifica,O.mica, andO.tangentafrom Utah;Macropsis borealis,M.rufescens,Oncopsis albicollis,O.incidens,O.interior,O.juno,O.marilynae,O.monticola, andO.tenuifoliaefrom northwestern North America;Macropsis dixiensisandO.infumatafrom southeastern North America;Macropsis decisa,M.jocosa,M.microceps,M.tunicata,M.xena,Oncopsis citrella,O.concurrens,O.dentata,O.deluda,O.prolixa,O.quebecensis, andO.vartyifrom northeastern North America; andMacropsis deviridis,Oncopsis citra,O.crispae, andO.prairianafrom Canada. Five new subspecies are described:O.cinctifrons kootenensis,O.prairiana ferrosus, andO.prairiana occidentalis, all from southern British Columbia;Oncopsis nigrinasi floridafrom Florida; andMacropsis deviridis albertafrom western Canada. Five new synonymies are created. Keys to all taxa, host associations, and distribution maps are provided and the colour phases of the various polymorphic species are analyzed.The morphology and significance of intersex individuals ofOncopsisspp. are discussed.
