Abstract

Four new cicada species within the genus Yoyetta Moulds, 2012 are described. Yoyetta bushi sp. nov. and Y. crepita sp. nov. are typically orange and black Yoyetta species. The current distribution of the former is principally in Blackbutt and Sydney Blue Gum forests at elevations above 500m in Girard State Forest and across much of Nymboi-Binderay National Park and its adjoining state forests in the Great Dividing Range of north-eastern New South Wales (NSW). Y. crepita sp. nov. currently has a limited distribution around Clandulla and Kandos in the Bylong Valley on the western slopes of the Great Dividing Range in NSW. Each of these two species call at rest and in flight. Y. nathani sp. nov. is a medium-sized, brown species found in the New England region of NSW with a current distribution from around Armidale, north to Bingara and Inverell. By comparison, Y. corbinorum sp. nov. is an impressive ‘burnt’-orange to black species with females distinctly larger than males. This species predominantly inhabits and calls from the upper branches of Mountain Ash eucalypt forests in the Yarra ranges of Victoria. Both Y. nathani sp. nov. and Y. corbinorum sp. nov. call at rest and rarely in flight.

The morphology of each species is described, along with sections on distinguishing features, distribution, habitat and behaviour. Calling song structures are provided and live specimens illustrated where appropriate.
