A new genus of grass cicadas (Hemiptera: Cicadoidea: Cicadidae) from Queensland, with descriptions of their songs
Five species of small (≤15 mm total length) grass cicadas are described in Graminitigrina gen. nov., of the subfamily Cicadettinae, Tribe Cicadettini. Three species occur in northern Queensland, two of which, G. karumbae sp. nov. and G. bowensis sp. nov., have distributions spanning linear distances of approximately 655 and 830km respectively. The third, G. triodiae sp. nov., is restricted to the Burra Range within White Mountains National Park. Two species, G. bolloni sp. nov. and G. carnarvonensis sp. nov., occur in southern to central Queensland; G. carnarvonensis restricted to the Mount Moffatt-Chesterton Range region of Carnarvon National Park, and G. bolloni within the area between Bollon, 60km north of St George, to near Jericho, spanning a linear distance of approximately 505km. The calling songs of each species are shown to be distinct, and constitute valuable taxonomic characters. Additional song types recognised and documented are: the ‘alarm (stress) song’, the 'short song' (both types recorded from G. bowensis) and the ‘ratchet song’, this common to four of the species described here. The calling song of G. bowensis is shown to vary in some temporal characteristics over at least part of its known distribution.
