All species of the families Cicadellidae, Eurymelidae and Membracidae described from Australia are listed, together with details of the primary type (type locality, type depository, collection details), known distribution and known hosts. Where appropriate. notes are given on nomenclature, biology and economic significance. Lectotypes are designated for Eurinoscopus sontiates Kirkaldy (Iassinae), Eutettix selbyi Evans (Deltocephalinae) and Empoasca australis Froggatt (Typhlocybinae). Idioscopus niveosparsus (Lethierry) (Idiocerinae) is recorded from Torres Strait islands, the first Australian records of this species. Ipoides brunomaculatus Evans (Eurymelidae : Ipoini) is recorded from Australia for the first time. The following nomenclatural changes are made. Batracomorphus pallas Knight is synonymised with Batracomorphus sontiates (Kirkaldy). Bythoscopus testaceus Walker is synonymised with Krisna kirbyi (Kirkaldy). Limotettix condylus Knight is synonymised with Limotettix pullatus (Evans). Vulturnus vappa Kirkaldy is synonymised with Neovulturnus vaedulcis (Kirkaldy). Nesosteles phryne Kirkaldy is synonymised with Nesoclutha pallida (Evans). The genus Diemoides Evans is reinstated from synonymy with Paralimnus Matsumura. Mitelloides mouldsi Stevens is emended to M . mouldsorum Stevens. Ledropsis froggatti Distant is given priority over L . crocina Distant. Macropsis fuscoguttatus, nom . nov., is proposed for Macropsis fuscopunctatus (Evans 1942). New combinations proposed are Ishidaella quadrata (Walker), Protartessus occidentalis (Jacobi), Stirellus mitis (Kirkaldy), Recilia vetus (Knight), Arawa detracta (Walker), Limotettix pullatus (Evans), Hecalus australis (Evans), Kahaono aneala (Kirkaldy), Zygina evansi (Ross), Zygina honiala (Kirkaldy), Zygina ipoloa (Kirkaldy), Zygina lubra (Kirkaldy), Zygina melanogaster (Kirkaldy) and Zygina sativae (Evans).
A new genus, Mayawa, is created for the Australian leafhopper species Limotettix capitatusKirkaldy (1907). Mayawa capitata (Kirkaldy) is redescribed and five new species, Mayawa carolae, Mayawa facialis, Mayawa flava, Mayawa fusca and Mayawa neoflava are added to the genus. Illustrations of all six species are provided, as is a key for their separation. The genus is restricted to Australia and the species are primarily grass‐feeding.
Siphanta ~t i l is redefined to include Parasalurnis Distant and Siphantoides Distant. Lombokia Distant is synonymized with Siphanta. The genus contains 40 species, 25 of which are described as new. Descriptions, redescriptions, measurements and illustrations are given of all 40 species. A key for separation of the species is included. The following new species are described: Kirkaldy = S. patruelis (St& Parasalurnis infumata Distant = Siphanta patruelis (~t i l ) ; Lombokia everefti Distant = Siphanta patruelis (st@; Parasalurnis insularis Distant = Siphanta roseicincta (Walker). The other species recognized are S. acuta (Walker), S. galeata Kirkaldy, S. nubecula Jacobi, S. anomala Jacobi, S. gregaria Jacobi, S. lucindae Kirkaldy, S. granulata Kirkaldy, S. rubra Schmidt and S. subgranulosa Kirkaldy.Revision of Siphanta 3 length of clavus length of tegrnen to apex of last branch of vein R width of tegmen from apex of clavus to costal margin level with end of costal cell length of vertex in midline width of vertex at base length of pronotum in midline length of frons in midline (from apex to frontoclypeal suture) maximum width of frons It maximum length of tegmen (in one species only)The following additional abbreviations were used in this work: AM Australian Museum, Type-species: Poeciloptera acuta Walker. Diagnostic FeaturesFrons slightly convex to flat, with median longitudinal carina. Lateral carinae very short or absent. Vertex flat, slightly undulate or slightly concave, meeting frons at carinate margin which may be triangularly produced, roundly convex or nearly straight. Pronotum medially flat between lateral carinae which curve posterolaterally and do not reach hind margin of pronotum; posterior margin broadly concave. Mesonotum with 2 lateral carinae, flattish medially. Occasionally, median carina faintly developed. Tegmen triangular with sutural angle obtusely rounded, right-angled or slightly acute. Tegmen lacking apical lines. Hind tibia with 1 spine on shaft. BiologyThe life history of Siphanta acuta was described by Myers (1922) in New Zealand, and Fletcher (1979a) briefly outlined the egglaying of the same species. As the ovipositors of all species of Siphanta are similar, it is likely that all species oviposit in a similar manner.Some species of the genus appear to have fairly wide food-plant ranges. This is evidenced by records of various species on exotic plants. Insufficient information is available to indi-4 M. J.

The following are the known food plants of species of Siphanta.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
