Abstract

Until now, the Australian fauna of Tetriginae has been represented predominantly by the genera Paratettix Bolívar, 1887 and Tetrix Latreille, 1802, with the latter mostly consisting of apterous species. The Australian members of these genera show remarkable morphological diversity, which prompted us to reexamine the relationships between them using cladistic analysis based on morphological characters of head and thorax. We have found that the Australian Tetrix spp. are easily separable into three distinct genera: Captivus gen. nov., Custodia gen. nov., and Enattor gen. nov. Additionally, we describe a new species of the Tetriginae genus Cyphotettix Rehn, 1952, C. ellurae sp. nov. We provide an identification key to the Australian Tetriginae genera and hypothesize that the apterous species are related to Tetrix collina Rehn, 1952.
