We conducted a comprehensive analysis of the phylogenetic, phylogeographic, and demographic relationships of Caspian cobra ( Eichwald, 1831) populations based on a concatenated dataset of two mtDNA genes (cyt and ND4) across the species' range in Iran, Afghanistan, and Turkmenistan, along with other members of Asian cobras ( subgenus Laurenti, 1768). Our results robustly supported that the Asiatic are monophyletic, as previously suggested by other studies. Furthermore, . and were recovered as sister taxa to each other, and in turn sister clades to . Our results also highlighted the existence of a single major evolutionary lineage for populations of in the Trans-Caspian region, suggesting a rapid expansion of this cobra from eastern to western Asia, coupled with a rapid range expansion from east of Iran toward the northeast. However, across the Iranian range of , subdivision of populations was not supported, and thus, a single evolutionary significant unit is proposed for inclusion in future conservation plans in this region.
我们基于伊朗、阿富汗和土库曼斯坦境内里海眼镜蛇（Eichwald，1831）整个分布范围内两个线粒体DNA基因（细胞色素b和ND4）的串联数据集，对其种群的系统发育、系统地理学和种群统计学关系进行了全面分析，同时还纳入了亚洲眼镜蛇（Laurenti亚属，1768）的其他成员。我们的结果有力地支持了亚洲眼镜蛇属单系群，正如其他研究所表明的那样。此外，[具体物种名1]和[具体物种名2]被发现是彼此的姐妹类群，进而又是[另一物种名]的姐妹分支。我们的结果还突显了里海地区里海眼镜蛇种群存在单一的主要进化谱系，这表明这种眼镜蛇从东亚迅速扩张到西亚，同时从伊朗东部向东北方向迅速扩大其分布范围。然而，在伊朗境内的里海眼镜蛇分布范围内，未发现种群细分情况，因此，建议将单一的进化显著单元纳入该地区未来的保护计划。
