A molecular phylogeny for the cicada tribe Thophini (Thopha + Arunta) is provided together with a cladistic analysis based on morphological data. A new subspecies, Thopha sessiliba clamoris, is described from the eastern fringe of the Pilbara region of Western Australia, based on molecular, morphological, and behavioral evidence. All described species of Thopha are figured and a revised key to the five species and two subspecies provided. A discussion on the biogeography of the genus is also included.
