Sulawesi is the largest, most topographically complex island in the Wallacean biogeographic zone, and it has a rich fauna of endemic small mammals, dominated by rodents of the family Muridae. Among murids, the Bunomys division is the most species‐rich radiation on Sulawesi. In total, the division contains 11 genera and 32 species, five and 20 of which are endemic to Sulawesi. We combined a five‐locus phylogeny and linear cranial morphology to better understand the taxonomy and local scales of endemism within the Bunomys division on Sulawesi. Phylogenetic analyses of mitochondrial and nuclear DNA placed B. fratrorum among other genera and inferred Paruromys as sister to the type species of Taeromys (T. celebensis). We resolve these issues by resurrecting Frateromys, a genus under which B. fratrorum was once placed, and returning Paruromys dominator to Taeromys. Within three species, F. fratrorum, T. callitrichus, and T. taerae, we recovered Pleistocene age divergences between populations sampled across the northern peninsula of Sulawesi; divergence between western and eastern populations of F. fratrorum may reflect the existence of two species.

苏拉威西岛上的地方性辐射-Bunomys师（Rodentia：Muridae）的分子和形态学系统

苏拉威西岛是华莱士生物地理区中最大，地形最复杂的岛屿，拥有丰富的地方小型哺乳动物动物区系，以鼠科科的啮齿类动物为主。在穆里德山脉中，Bunomys分区是苏拉威西岛上物种最多的辐射。该部门共有11属32种，其中5种和20种是苏拉威西特有的。我们结合了五位元系统发育和线性颅骨形态，以更好地了解苏拉威西岛上的Bunomys部门内的分类学和地方性地方尺度。线粒体和核DNA的系统发育分析置于B. fratrorum除其他属和推断Paruromys作为姐妹的类型物种西里伯斯鼠属（T. celebensis）。我们通过复活解决这些问题Frateromys，其下一个属B. fratrorum曾经放置，并返回Paruromys支配到西里伯斯鼠属。在三个物种中，F。fratrorum，T。callitrichus和T. taerae，我们恢复了苏拉威西岛北部半岛采样的种群之间的更新世年龄差异。F. fratrorum的西部和东部种群之间的差异可能反映了两个物种的存在。
