Cicadas tend to be affected by vicariance reflecting poor mobility of nymphs underground and weak flying ability of adults. However, modern collection records of invasive cicada, combined with records of typhoon tracks, and newly obtained phylogeographic data suggest long distance, relatively instantaneous, dispersal of some vicariantly speciated cicadas. We address the importance of this typhoon dispersal mechanism applied to representative species of east Asian endemic cicadas of Cryptotympana, Mogannia, Euterpnosia and Meimuna. We combine BEAST-dated phylogenic and haplotype network analyses, modern collection data of non-native cicadas available in reports of the Japanese insect associations, modern typhoon records by Japan Meteorological Agency, and our own Quaternary geological constriction data. In conclusion, although Ryukyu endemic cicadas were vicariantly speciated, endemic cicadas on some islands were accidentally dispersed long distances to another island possibly by typhoons, particularly those associated with super typhoons generated since 1.55 Ma.
蝉类往往受到隔离分化的影响，反映出若虫在地下移动能力差和成虫飞行能力弱。然而，入侵蝉的现代采集记录，结合台风轨迹记录和新获得的系统地理学数据，表明一些隔离分化的蝉能够进行长距离、相对瞬间的扩散。我们研究了这种台风扩散机制对东亚特有蝉类Cryptotympana、Mogannia、Euterpnosia 和 Meimuna 代表种的重要性。我们结合了 BEAST 年代测定的系统发育和单倍型网络分析、日本昆虫协会报告中可获得的非本地蝉的现代采集数据、日本气象厅的现代台风记录以及我们自己的第四纪地质收缩数据。总之，尽管琉球特有蝉是隔离分化形成的，但一些岛屿上的特有蝉可能是由于台风的偶然长距离扩散到另一个岛屿，特别是那些与 155 万年前以来生成的超强台风有关的岛屿。
