All described species of cicadas (Cicadidae) from the Northern Territory and South Australia are listed (Tables 1 and 2) and the composition of these faunas is briefly compared and discussed. Five new genera and 12 new species are described from arid regions of Western Australia, Northern Territory, South Australia and New South Wales, viz. Amica glauca gen. et sp. nov., Amica sitis gen. et sp. nov., Arenopsaltria exmouthensis sp. nov., Arenopsaltria dryas sp. nov., Austropunia cheloides gen. et sp. nov., Brevia bullula gen. et sp. nov., Paraclinata chlorotes gen. et sp. nov., Paraclinata nullarboris gen. et sp. nov., Cognadanga capricornica gen. et sp. nov., Cognadanga isos gen. et sp. nov., Gudanga kolos sp. nov. and Xeropsalta eremica sp. nov. Notes on the attributes of Heremusina Ewart, 2018 are reviewed and discussed. Correction is provided for a misidentification of Paradina leichardti (Distant, 1882) in the molecular study of Marshall et al. (2018).
