Integrative taxonomy combines different data sources as a way to detect separately evolving metapopulation lineages or species. This method is applied to cicada populations found in northern Sardinia, based on acoustic, morphological and ecological data. Thereby, the genus Tibicina turned out to be more diverse than previously expected. Besides the anticipated Tibicina corsica corsica and T. nigronervosa, both scientifically described from the neighbouring island of Corsica, two poorly or previously unknown species have been discovered. Tibicina longisyllaba sp. nov. is here described as new. Tibicina corsica s.l. forms a small species complex where syllable periods of the song – the movement cycle of the acoustic organs – are specific without overlaps. Some coloration and hair cover characters, as well as the shape of the song apparatus, are not diagnostic on their own, but highly significant between species. Species occur sympatrically, parapatrically or allopatrically and prefer specific habitats from grassland to closed forests. All four Tibicina taxa are endemic to parts of Sardinia or to the Corso-Sardinian archipelago. The new findings are important for biodiversity conservation and public awareness. The loud, strident calling songs dominate the summer sounds of the islands. The group could form a showcase with respect to biogeography, phylogeny, speciation and sound production.

仔细观察并仔细聆听：撒丁岛北部的意想不到的蝉多样性，并带有新物种的描述（蝉科：Tibicina）

综合分类法结合了不同的数据源，以作为一种方法来分别检测正在进化的亚种群谱系或物种。根据声学，形态和生态学数据，该方法适用于撒丁岛北部的蝉种群。因此，蒂比西那属比以前预期的更加多样化。除了预期Tibicina科西嘉岛科西嘉岛和T. nigronervosa，无论是从科西嘉岛附近岛屿的科学描述，两名不佳或以前未知的物种被发现。Tibicina longisyllaba sp。十一月 在这里被描述为新的。Tibicina corsica sl形成一个小物种的复合体，其中歌曲的音节周期（声学器官的运动周期）是特定的，没有重叠。某些颜色和头发遮盖特征以及歌曲的形状本身并不能诊断，而在物种之间却非常重要。物种同生，同伴生或异特异地发生，并且偏爱从草地到封闭森林的特定栖息地。四个蒂比西纳分类单元都是撒丁岛部分地区或科索-撒丁岛群岛的特有种。新发现对保护生物多样性和提高公众认识至关重要。响亮刺耳的歌声主宰着岛屿的夏日之声。该小组可以在生物地理学，系统发育，物种形成和声音产生方面形成展示。
