舜达弧形成了一个几乎连续的岛链，因此是东南亚大陆和美拉尼西亚之间潜在的扩散走廊。然而，舜达群岛的地质历史有很大不同，这可能对实际的扩散路线和社区集会产生了重要影响。在这里，我们揭示了超多样化和不会飞的三角翅目象甲的生物地理史。不同的祖地重建方法表明了一个从东到西的复杂范围扩张。在新几内亚之外，三翼鸟多次越过莱德克防线到达摩鲁加和苏拉威西群岛。苏拉威西多次充当舜达弧不同部分的殖民中心。西爪哇、东爪哇和巴厘岛被认为是不同的生物地理区域。物种的时间和多样性在很大程度上与岛屿出现的地质年代相吻合。殖民并没有受到传统生物地理边界的限制，比如华莱士线。相反，殖民模式支持距离相关的扩散和岛屿年龄限制的扩散。
The Sunda Arc forms an almost continuous chain of islands and thus a potential dispersal corridor between mainland Southeast Asia and Melanesia. However, the Sunda Islands have rather different geological histories, which might have had an important impact on actual dispersal routes and community assembly. Here, we reveal the biogeographical history of hyperdiverse and flightless Trigonopterus weevils. Different approaches to ancestral area reconstruction suggest a complex east to west range expansion. Out of New Guinea, Trigonopterus repeatedly reached the Moluccas and Sulawesi transgressing Lydekker′s Line. Sulawesi repeatedly acted as colonization hub for different segments of the Sunda Arc. West Java, East Java and Bali are recognized as distinct biogeographic areas. The timing and diversification of species largely coincides with the geological chronology of island emergence. Colonization was not inhibited by traditional biogeographical boundaries such as Wallace’s Line. Rather, colonization patterns support distance dependent dispersal and island age limiting dispersal.
