洲际生物间断已被记录和分析在许多泛北极类群。模式以前合成的动物相比，植物表明，动物分离的时间大多是早第三纪，并产生迁移和vicariance事件发生在北大西洋，而植物分离大多是中晚第三纪，意味着迁移和vicariance在Beringia。Melaphidina aphids（半翅目：蚜虫科：Fordini）表现出主机交替的生活周期，包括一个专性的季节性转变之间的边缘亚属漆树物种（漆树科）和苔藓（苔藓植物门）。与它们的漆树宿主相似，黑蚜分布在东亚和北美东部之间。我们研究了Melaphidina内的进化关系，以确定北美血统的位置，日期从亚洲的亲戚分歧，并将这些结果与以前的历史漆树地理研究。我们采样了9个种和3个亚种，代表所有6个属的Melaphidina。数据包括线粒体细胞色素c氧化酶亚基I和II +亮氨酸tRNA、细胞色素B和核延伸因子Ia基因的序列。系统发育分析（Bayesian，maximum-likelihood，parsimony）结果表明，除Nurudea和Schlechtendalia外，所有属的系统发育均为单系。猪富士。虽然北美Melaphis的确切位置没有得到很好的解决，但在亚洲分类群中有很高的支持。Melaphis与亚洲近缘种的分歧集中在始新世-渐新世界线（类似于33-35 Ma），这与Beringian陆桥I的关闭相吻合。这也对应于亚洲-北美间断先前估计的漆树亚属。我们建议晚始新世白令陆桥作为最有可能的迁移路线Melaphis的祖先，也假设北美漆树的祖先。Melaphidina分离的结果从动物谱系中的模式模式出发，并提出了一个案例，昆虫和寄主植物类群显然类似于第三纪气候变化的反应。(C)2013 Elsevier Inc.

Intercontinental biotic disjunctions have been documented and analyzed in numerous Holarctic taxa. Patterns previously synthesized for animals compared to plants suggest that the timing of animal disjunctions are mostly Early Tertiary and were generated by migration and vicariance events occurring in the North Atlantic, while plant disjunctions are mostly Mid-Late Tertiary and imply migration and vicariance over Beringia. Melaphidina aphids (Hemiptera: Aphididae: Fordini) exhibit host-alternating life cycles comprising an obligate seasonal shift between Rims subgenus Rhus species (Anacardiaceae) and mosses (Bryophyta). Similar to their Rhus hosts, melaphidines are distributed disjunctly between Eastern Asia and Eastern North America. We examined evolutionary relationships within Melaphidina to determine the position of the North American lineage, date its divergence from Asian relatives, and compare these results to a previous historical biogeographic study of Rhus. We sampled nine species and three subspecies representing all six genera of Melaphidina. Data included sequences of mitochondrial cytochrome c oxidase subunits I and II + leucine tRNA, cytochrome b, and nuclear elongation factor la genes. Phylogenetic analyses (Bayesian, maximum-likelihood, parsimony) of the combined data (3282 bp) supported the monophyly of all genera except Nurudea and Schlechtendalia, due to the position of N. ibofushi. While the exact position of the North American Melaphis was not well resolved, there was high support for a derived position within Asian taxa. The divergence of Melaphis from Asian relatives centered on the Eocene-Oligocene boundary (similar to 33-35 Ma), which coincides with closure of Beringian Land Bridge I. This also corresponded to the Asian-North American disjunction previously estimated for subgenus Rhus spp. We suggest the late-Eocene Bering Land Bridge as the most likely migration route for Melaphis ancestors, as was also hypothesized for North American Rhus ancestors. Results for the Melaphidina disjunction depart from the modal pattern in animal lineages, and present a case where insect and host-plant taxa apparently responded similarly to Tertiary climate change.
