利用线粒体DNA细胞色素b基因序列对13种林鼠的系统关系进行了研究。吝啬，可能性，和邻居加入分析在大多数情况下产生类似的拓扑结构，并产生六个系统的结论。首先，在N. floridana magister（N.大法官）。其次，为N. albigula（N. albigula和N. leucodon）和N. mexicana（N. mexicana、墨西哥拟单胞菌N. isthmica，和N. picta）。第三，Neotoma亚属由四个种组组成（佛罗里达，lepida，mexicana和micropus）。第四，为N. stephensi属于鳞翅目物种组。第五，支持承认Hodomys是一个单独的属，是Xenomys的姐妹。第六，支持的海拔亚属Teonoma属的地位进行了讨论。(C)2002 Elsevier Science（美国）。All rights reserved.
DNA sequences from the mitochondrial DNA cytochrome-b gene were used to infer the systematic relationships of 13 species of wood rats (genus Neotoma). Parsimony, likelihood, and neighbor-joining analyses produced similar topologies in most cases and produced six systematic conclusions. First, results of previous studies were supported in the recognition of N. floridana magister as distinct species (N. magister). Second, evidence was provided for the recognition of cryptic species within N. albigula (N. albigula and N. leucodon) and N. mexicana (N. mexicana, N. isthmica, and N. picta). Third, the subgenus Neotoma is composed of four species groups (floridana, lepida, mexicana, and micropus). Fourth, support was provided for placement of N. stephensi within the lepida species group. Fifth, support was provided for the recognition of Hodomys as a separate genus, sister to Xenomys. Sixth, support for the elevation of the subgenus Teonoma to generic status is discussed.
