Helleria brevicornis has a disjunct, peri-Tyrrhenian distribution that mirrors that of several organisms, for which geographic vicariance is invoked, due to the geological events started with the Oligocene split of the Sardo-Corsican microplate from the Pyrenees, and successive separation between Sardinia and Corsica. Molecular phylogenetic analyses demonstrated that such a biogeographic model does not apply to Helleria. The original split of the Sardinian and Corsican lineages originated in the Early Pliocene. Further diversification occurred later. The colonization of the Tuscan archipelago, French, and Italian mainland occurred most recently, but a possible time dependency bias suggests that such colonization was driven by human-transport.
短角叶蜡石属具有不连续的、环蒂勒尼安分布，这与由于地质事件导致的几个生物地理隔离现象相似，这些地质事件始于上新世撒丁-科西嘉微板块与比利牛斯山脉的分离，以及随后撒丁岛和科西嘉岛之间的分离。分子系统发育分析表明，这种生物地理模式不适用于短角叶蜡石属。撒丁岛和科西嘉岛谱系的最初分离发生在早更新世。后来进一步多样化。托斯卡纳群岛、法国和意大利大陆的殖民化发生在最近，但可能存在时间依赖性偏差，表明这种殖民化是由人类运输驱动的。
