Five new species are described in the genus Yoyetta Moulds, each belonging to the Yoyetta tristrigata (Goding and Froggatt) species group. Yoyetta australicta n. sp. occurs in southern eucalypt woodlands in two separate populations, one extending from the foothills of the Mt Lofty Ranges and southern fringes of Adelaide north to the Flinders Ranges, and the other from Warrumbungle National Park and from Clandulla, near Orange and near Grenfell in New South Wales south to Mt Taylor in the Australian Capital Territory. Yoyetta corindi n. sp. has a restricted, coastal and subcoastal warm temperate distribution in north-eastern New South Wales open forest communities between Trustums Hill and Arrawarra, extending inland from south-west of Grafton to Tyringham. Yoyetta delicata n. sp. has an inland warm temperate distribution in eucalypt woodland and open forest from near Killarney and west of Warwick in south-east Queensland south to Cassilis and near Wyong in central New South Wales. Yoyetta ignita n. sp. is found from Flinders Peak and Mt Tamborine in south-east Queensland, south along the Great Dividing Range (and inland to Mt Kaputar) in New South Wales, with a disjunct population on the eastern slopes of Mt Ainslie in the Australian Capital Territory. Yoyetta robusta n. sp. is found from the Granite Belt in south-east Queensland south to the Glenn Innes area in northern New South Wales. The new species are all smallmedium sized cicadas (1525 mm body length) with male calling songs that are distinguishable from one another and from other species in the genus. In three of the new species (Y. australicta n. sp., Y. corindi n. sp. and Y. robusta n. sp.), the songs are characterised by sharp, high energy ticks or clicks, produced mainly in flight. Each of these species also produces ticks or clicks, sometimes in combination with a short buzz, while stationary. Of the remaining two species, one (Y. delicata n. sp.) produces a soft, coarse buzzing song while stationary and the other (Y. ignita n. sp.) produces a combination of buzzes and clicks while stationary. A key to species in the Y. tristrigata species group is provided.
描述了五个新物种，每个物种都属于 Yoyetta tristrigata (Goding and Froggatt) 物种组。Yoyetta australicta n. sp. 分布在南澳大利亚的桉树林地中，有两个独立的种群，一个从洛夫蒂山脉的山麓和阿德莱德的南部边缘向北延伸到弗林德斯山脉，另一个从沃伦邦国家公园和奥兰治附近的克兰德拉，以及新南威尔士州格伦费尔附近向南延伸到澳大利亚首都领地的泰勒山。Yoyetta corindi n. sp. 分布在新南威尔士州东北部沿海和亚热带温暖地区的开阔森林群落中，从 Trustums Hill 和 Arrawarra 之间，从格拉夫顿西南部向 Tyringham 内陆延伸。Yoyetta delicata n. sp. 分布在昆士兰州东南部的桉树林地和开阔森林中，从基拉尼附近到沃里克西部，向南延伸到卡西尔和新南威尔士州中部的怀昂，分布范围属于内陆温暖温带。Yoyetta ignita n. sp. 分布在昆士兰州东南部的芬德斯峰和 Tamborine 山，沿着大分水岭（内陆延伸到 Kaputar 山）在新南威尔士州，在澳大利亚首都领地的 Ainslie 山东部山坡上有一个不连续的种群。Yoyetta robusta n. sp. 分布在昆士兰州东南部的花岗岩带，向南延伸到新南威尔士州北部的格伦因尼斯地区。这些新物种都是中小型蝉（体长 15-25 毫米），雄性的求偶叫声彼此之间以及与属中的其他物种都有所不同。在三个新物种（Y. australicta n. sp.、Y. corindi n. sp. 和 Y. robusta n. sp.）中，这些歌声的特点是发出尖锐、高能量的鸣叫或咔哒声，主要在飞行中产生。这些物种中的每一个都能发出鸣叫或咔哒声，有时在静止时也能发出短促的嗡嗡声。在剩下的两个物种中，一个（Y. delicata n. sp.）在静止时发出柔和、粗糙的嗡嗡声，另一个（Y. ignita n. sp.）在静止时发出嗡嗡声和咔哒声的组合。提供了 Y. tristrigata 物种组中物种的关键特征。
