A new genus, Tyligma gen. nov. , is created within Cixiini to accommodate the new species Tyligma dandavalex sp. nov. Tyligma is characterised by a swollen postclypeus and is closely related to the Australian genera Chidaea Emeljanov, 2000, and Leades Jacobi, 1928, but differs in the shape of the ventral ridge of the aedeagus in males and several other characters presented here. Occurring in the Australian Capital Territory, New South Wales, Queensland, and Victoria, the genus is restricted to eastern Australia. The species emerges in spring, feeding on native shrubs and small trees of Asteraceae and Myrtaceae and on the invasive West Palaearctic ash species Fraxinus angustifolia . In addition, we provide an updated key to the genera of Australian Cixiini.
