Our analyses included more than 100 individuals in 63 recognized species from 19 genera, including all but six genera of the Rattus sensu lato. The major findings of our work include: 1) confirmation of a three way division of Rattus sensu lato into 'Maxomys',Niviventer' and 'Rattus' groups; 2) previously unsuspected association of the specialized arboreal genus Margaretamys of Sulawesi with the Niviventer group; 3) demonstration that the genus Rattus as currently defined is polyphyletic with at least three recognizable lineages: i) Rattus sensu stricto, which includes both R. norvegicus and R. rattus, along with many other species of particular interest; ii) 'Rattus' everetti of the Philippines; and iii) members of the 'Rattus' xanthurus' group together with the native 'Rattus' of Australia and New Guinea; 4) demonstration that the black rat group, Rattus rattus sensu lato contains multiple lineages, two of which are shown to be genetically and cyctologically distinct in Japan but with evidence of introgression in several areas with contrasting outcomes. From a biogeographic perspective, the most interesting findings of this study are the demonstration that members of Rattus sensu lato succeeded in colonizing the oceanic landmasses off the margins of the Sunda Shelf on multiple occasions. All major groups within Rattus sensu lato managed to reach Sulawesi, the Philippine islands and the Mentawai islands to the south of Sumatra, but only one lineage within the 'Rattus group' succeeded in going beyond these major islands to eventually colonize New Guinea and Australia in the east, and to reach the remote islands of the Ryukyu Archipelago in the north.

我们的分析包括来自19个属的63个公认物种中的100多名个体，包括除6属Rattus sensu Lato。我们工作的主要发现包括：1）确认Rattus sensu Lato的三道划分为“ Maxomys”，Niviventer'和“ Rattus”群体； 2）先前未经引起的苏拉威西植物玛格丽塔属与Niviventer组的关联； 3）证明了当前定义的拉图斯属具有至少三个可识别的谱系：i）包括R. norvegicus和R. rattus在内的Rattus sensu stricto，以及许多其他特别感兴趣的物种； ii）菲律宾的“拉图斯”；和iii）“黄褐色”小组的成员以及澳大利亚和新几内亚的本地“拉图斯”； 4）证明了黑色大鼠群，拉图斯·森格·拉托（Rattus rattus sensu Lato）包含多个谱系，其中两个谱系在日本在遗传和胞学上是在遗传学和胞学上截然不同的，但在几个具有对比结果的领域渗入。从生物地理学的角度来看，这项研究的最有趣的发现是证明了Rattus Sensu Lato的成员成功地将Sunda架子边缘的海洋陆地殖民了多次。 All major groups within Rattus sensu lato managed to reach Sulawesi, the Philippine islands and the Mentawai islands to the south of Sumatra, but only one lineage within the 'Rattus group' succeeded in going beyond these major islands to eventually colonize New Guinea and Australia in the east, and to reach the remote islands of the Ryukyu Archipelago in the north.
