Moulds (2012) established the genus Mugadina for two small cicadas, M. marshalli (Distant) and M. emma (Goding and Froggatt), both grass inhabiting species known from Queensland and New South Wales. Both species are notable for their relatively simple 'ticking' songs. Moulds further noted that there were at least two superficially similar genera of cicadas, but each with different genitalia. This paper describes two new genera of small (9-15 mm body lengths) and distinctive grass cicadas with genitalia that are very similar to those of Mugadina, but possess clear morphological, colour and calling song differences. The new genera are: Heremusina n. gen. with two known species namely H. udeoecetes n. sp. and H. pipatio n. sp.; the second new genus is Xeropsalta n. gen., containing four known species, X. thomsoni n. sp., X. aridula n. sp., X. rattrayi n. sp., and X. festiva n. comb. Heremusina n. gen. species are described from the Alice Springs area of Northern Territory and the Cloncurry area of northwest Queensland, from arid to semi arid habitats. The Xeropsalta n. gen. species are described from western, southwest and central Queensland, and from the Simpson and Strzelecki Deserts in northeastern South Australia and northwestern New South Wales, respectively, all locations in very arid to arid habitats, but close to seasonal (often irregular) rivers and lakes. X. festiva n. comb. occurs in semi arid habitats in southern and southeastern Australia. Detailed taxonomic descriptions are provided of the new species, together with distributions, habitats, and the calling songs. The Heremusina species emit songs with short repetitive buzzing echemes, the echeme durations differing between each species. The Xeropsalta songs are notable for their complexity, containing multiple elements with rapid changes of amplitudes and temporal structures, rather atypical of the songs of most small grass dwelling cicadas. Detailed song structures distinguishing each of the species are illustrated and interpreted in each case in light of their respective taxonomic status.
莫尔兹（2012年）为两种小型蝉建立了穆加迪纳属，即马绍尔穆加迪纳蝉（迪斯坦特）和艾玛穆加迪纳蝉（戈丁和弗罗加特），这两种蝉均栖息于草丛，在昆士兰州和新南威尔士州被发现。这两个物种均以其相对简单的“滴答”声而闻名。莫尔兹还指出，至少有两个表面上相似的蝉属，但它们的生殖器不同。本文描述了两个新的小型（体长9 - 15毫米）且独特的草丛蝉属，其生殖器与穆加迪纳属非常相似，但在形态、颜色和鸣声上存在明显差异。这两个新属分别是：赫雷穆西纳新属，已知有两个物种，即乌德奥埃切特斯赫雷穆西纳新种和皮帕蒂奥赫雷穆西纳新种；第二个新属是旱栖蝉新属，包含四个已知物种，即汤姆森旱栖蝉新种、干旱旱栖蝉新种、拉特雷伊旱栖蝉新种和节庆旱栖蝉新组合种。赫雷穆西纳新属的物种是在北领地的爱丽丝泉地区和昆士兰州西北部的克隆卡里地区被描述的，栖息地从干旱到半干旱。旱栖蝉新属的物种分别来自昆士兰州西部、西南部和中部，以及南澳大利亚州东北部和新南威尔士州西北部的辛普森沙漠和斯特雷泽莱茨沙漠，所有这些地点都处于非常干旱到干旱的栖息地，但靠近季节性（通常不规律）河流和湖泊。节庆旱栖蝉新组合种出现在澳大利亚南部和东南部的半干旱栖息地。本文提供了新物种的详细分类描述，以及分布、栖息地和鸣声。赫雷穆西纳属的物种发出的鸣声具有短的重复嗡嗡声模式，每个物种的模式持续时间不同。旱栖蝉属的鸣声以其复杂性著称，包含多个元素，振幅和时间结构快速变化，这在大多数小型草丛栖息蝉的鸣声中并不典型。针对每个物种，根据其各自的分类地位，对区分它们的详细鸣声结构进行了图示和解释。
