草蛇（Natrix natrix）是欧洲分布最广，在许多地区最常见的蛇类，有许多形态上定义的亚种。然而，草蛇的分类研究相对较少，最近的工作表明，形态定义的亚种和地理分化之间存在重大冲突。利用外部形态学、骨骼学特征以及13个微卫星位点和两个线粒体标记的信息，我们研究了N. n.产于北非马格里布地区、伊比利亚半岛和邻近的法国。根据以往的研究，N. n. astreptophora对应于一个非常分歧的线粒体分支，并构成了所有剩余草蛇的姐妹分类群。在法属比利牛斯山地区，存在一个N. n. astreptophora与另一亚种，N. n.瑞士字体。我们的微卫星和线粒体DNA的分析表明，这两个类群的分布范围相邻，但两者只在例外情况下杂交。尽管草蛇的许多形态特征高度变异和同源，但N. n.星蛇与其他草蛇的不同之处在于其红色的虹膜颜色，腹部鳞片明显较少，头骨形态也不同。进一步考虑N. n. astreptophora和N. n. helvetica，并承认N. n.与其他亚种的亲缘关系，我们认为斑游蛇（Natrix astreptophora，Seoane，1884）应被认为是一个独立的种。需要进一步的研究来探索N。astreptophora是多型的，因为单个样品的N.来自突尼斯的astreptophora在遗传上与其欧洲同类高度不同。
The grass snake (Natrix natrix) is Europe’s most widely distributed and, in many regions, most common snake species, with many morphologically defined subspecies. Yet, the taxonomy of grass snakes is relatively little studied and recent work has shown major conflicts between morphologically defined subspecies and phylogeographical differentiation. Using external morphology, osteological characters, and information from 13 microsatellite loci and two mitochondrial markers, we examine differentiation of the subspecies N. n. astreptophora from the North African Maghreb region, the Iberian Peninsula and neighbouring France. According to previous studies, N. n. astreptophora corresponds to a deeply divergent mitochondrial clade and constitutes the sister taxon of all remaining grass snakes. In the French Pyrenees region, there is a contact zone of N. n. astreptophora with another subspecies, N. n. helvetica. Our analyses of microsatellites and mitochondrial DNA reveal that the distribution ranges of the two taxa abut there, but both hybridize only exceptionally. Even though many morphological characters are highly variable and homoplastic in grass snakes, N. n. astreptophora differs consistently from all other grass snakes by its reddish iris coloration and in having significantly fewer ventral scales and another skull morphology. Considering further the virtual absence of gene flow between N. n. astreptophora and N. n. helvetica, and acknowledging the morphological distinctiveness of N. n. astreptophora and its sister group relationship to all remaining subspecies of grass snakes, we conclude that Natrix astreptophora (Seoane, 1884) should be recognized as a distinct species. Further research is needed to explore whether N. astreptophora is polytypic because a single sample of N. astreptophora from Tunisia turned out to be genetically highly distinct from its European conspecifics.
