全北极鼠蛇（Elaphe auct.）的系统发育关系是从两个线粒体基因12S rRNA和COI部分推断出来的。Elaphe Fitzinger是由十个古北极物种组成的。在古北西部，有4种（hohenackeri、lineatus、persicus和situla）属于Zamenis Wagler。其系统发育亲缘关系与密切相关的属，冠状属和卵冠属，仍不清楚。东亚紫叶甘蓝属（colber porphyraceus Cantor）为新属。这个分类群和西欧角鼻蛇在旧大陆的鼠蛇中有一个孤立的地位。另一个新属描述了四个东方物种（cantoris, hodgsonii， moellendorffi和taeniurus）。新世界大鼠蛇及其相关属是单系的。黄锥虫被称为Pseudelaphe Mertens和Rosenberg。对于Coluber guttatus L.（模式种）和其他新北极物种（bairdi， obsoletus和vulpinus），重新验证了Pantherophis Fitzinger。Senticolis triaspis是包括Arizona属、Bogertophis属、Lampropeltis属、Pituophis属和Rhinocheilus属在内的新世界鼠蛇的姐妹分类群。东亚大鼠蛇（Coluber illatus Boie）和大鼠蛇（Coluber mandarinus Cantor）与其他全北极鼠蛇属形成一个单系外群，统称为Euprepiophis Fitzinger。三个旧大陆种，即Elaphe (sensu lato) bella、E. (s.l.) frenata和E. (s.l.) prasina仍未被划分。不同的鼠蛇群（Lampropeltini部落）表现出典型的半阴茎特征。
The phylogenetic relationships of the Holarctic ratsnakes (Elaphe auct.) are inferred from portions of two mitochondrial genes, 12S rRNA and COI. Elaphe Fitzinger is made up of ten Palaearctic species. Natrix longissima Laurenti (type species) and four western Palaearctic species (hohenackeri, lineatus, persicus, and situla) are assigned to Zamenis Wagler. Its phylogenetic affinities with closely related genera, Coronella and Oocatochus, remain unclear. The East Asian Coluber porphyraceus Cantor is referred to a new genus. This taxon and the western European Rhinechis scalaris have an isolated position among Old World ratsnakes. Another new genus is described for four Oriental species (cantoris, hodgsonii, moellendorffi, and taeniurus). New World ratsnakes and allied genera are monophyletic. Coluber flavirufus Cope is referred to Pseudelaphe Mertens and Rosenberg. Pantherophis Fitzinger is revalidated for Coluber guttatus L. (type species) and further Nearctic species (bairdi, obsoletus, and vulpinus). Senticolis triaspis is the sister taxon of New World ratsnakes including the genera Arizona, Bogertophis, Lampropeltis, Pituophis, and Rhinocheilus. The East Asian Coluber conspicillatus Boie and Coluber mandarinus Cantor form a monophyletic outgroup with respect to other Holarctic ratsnake genera and are referred to Euprepiophis Fitzinger. Three Old World species, viz. Elaphe (sensu lato) bella, E. (s.l.) frenata, and E. (s.l.) prasina remain unassigned. The various groups of ratsnakes (tribe Lampropeltini) show characteristic hemipenis features.
