Archdukes, barons, counts, dukes and marquises are forest-dwelling butterflies found in mainland Asia and most islands of the Indo-Australian archipelago west of Wallace’s Line, with only a few species occurring as far east as the Bismarck Archipelago. This pattern is unusual among butterfly groups of the region, which often present more widespread geographical ranges bearing little signature of Lydekker’s and Wallace’s Lines. Using a molecular multimarker matrix, we infer the first dated phylogeny for this clade and estimate its biogeographical history. We recover the Oriental genus Euthalia as polyphyletic, although other genera are monophyletic. The clade originated in continental Indomalaya in the late Oligocene ~24 Mya, when the Indo-Australian archipelago was at one of the most dynamic stages of its orogeny. Multiple independent colonization events towards the Lesser Sunda Islands, Moluccas, Australia and New Guinea suggest the relative permeability of Lydekker’s and Wallace’s Lines to these butterflies. Colonization of Melanesia took place twice, probably before the recent formation of Sulawesi. The study of Indo-Australian Adoliadini provides additional evidence that biogeographical barriers long thought to prevent exchange between the Asian and Australian biotas are, in fact, permeable especially to vagile insect lineages in the region.

在印度-澳大利亚地质迷宫上滑行：大公爵，大公爵和公爵在Lydekker和Wallace's线的反复侵袭（Nymphalidae：Limenitidinae：Adoliadini）

大公，贵族，伯爵，公爵和侯爵是在亚洲大陆和华莱士之线以西的印度-澳大利亚群岛的大多数岛屿上发现的居住在森林中的蝴蝶，只有极少数物种出现在the斯麦群岛以东。这种模式在该地区的蝴蝶群中是不寻常的，它们通常表现出更广泛的地理范围，几乎没有Lydekker和Wallace的线的特征。使用分子多标记矩阵，我们推断出该进化枝的第一个系统发育史，并估计了其生物地理历史。我们恢复东方属Euthalia作为多系的，尽管其他属是单系的。该进化枝起源于渐新世〜24 Mya晚期的Indomalaya大陆，当时印度-澳大利亚群岛处于造山运动最活跃的阶段之一。对小Sun他群岛，莫卢卡斯，澳大利亚和新几内亚的多次独立殖民事件表明，Lydekker和Wallace系对这些蝴蝶的相对渗透性。美拉尼西亚的殖民化发生了两次，大概是在苏拉威西岛最近成立之前。对印度-澳大利亚人Adoliadini的研究提供了其他证据，长期以来人们认为阻止亚洲和澳大利亚生物群之间交换的生物地理障碍实际上是可渗透的，尤其是该地区易变的昆虫谱系可以渗透。
