Auchenorrhyncha: (Insecta: Hemiptera): catalogue.
The species-group names of all New Zealand Cicadomorpha and Fulgoromorpha were catalogued with distribution records and their biology and wing condition (as indicative of flight ability) were also discussed. The composition of the New Zealand auchenorrhyncha fauna and its affinities with Australia, Lord Howe Island, Norfolk Island, and New Caledonia were analysed. The fauna had the greatest affinity to Eastern continental Australia. Twenty-four introduced taxa occurs in New Zealand, including economically important species, e.g., Philaenus spumarius, Anzygina dumbletoni, Edwardsiana froggatti, Eupteryx melissae, Orosius argentatus, Ribautiana tenerrima, Rhytidodus decimaquartus (Rhytidodus decimusquartus), Anzora unicolor, and Scolypopa australis. New combinations were recorded: Arawa negata comb. nov. for Athysanus negatus, Nesoclutha phryne comb. nov. for Nesoclutha pallida, Cermada inexspectata comb. nov. for Cixius inexspectatus, and Cermada triregia comb. nov. for Cixius triregius. Arawa salubris is the synonym of Arawa negata. The following Cicadellidae taxa have been incorrectly recorded or doubtfully established in New Zealand: Alodeltocephalus obliquus, Balclutha rieki, Edwardsiana crataegi, Japananus hyalinus, Limotettix incertus, and Paracephaleus montanus. The cicadellid genus Athysanus is excluded from the fauna. The areas of New Zealand showing the highest taxonomic diversity are: North Island - Wellington (73 species-group taxa), Auckland (64), Northland (60); South Island - Northwest Nelson (65), Mid Canterbury (56). The areas with the highest number of New Zealand endemics are: North Island-Wellington (63 species-group taxa), Northland (47), Taupo (46), Auckland (45), Bay of Plenty (40); South Island-Northwest Nelson (50), Buller (45), Mid Canterbury (40). The areas known for the highest number of local endemics are: North Island-Northland (5), Wellington (5); South Island-Northwest Nelson (4). New Zealand Auchenorrhyncha are generally diurnal and live in lowland to mountain forests and shrublands, although a number of groups are found typically in open habitats such as tussock grasslands and in subalpine environments. Parasitic wasps, birds, predatory beetles, spiders, and mites may be among the major natural enemies of New Zealand Auchenorrhyncha.
