The monophyletic species subgroup of Podarcis tauricus is distributed in the western and southern parts of the Balkans, and includes four species with unresolved and unstudied inter- and intra-specific phylogenetic relationships. Using sequence data from two mitochondrial and three nuclear genes and applying several phylogenetic methods and species delimitation approaches to an extensive dataset, we have reconstructed the phylogeny of the Podarcis wall lizards in the Balkans, and re-investigated the taxonomic status of the P. tauricus species subgroup. Multilocus analyses revealed that the aforementioned subgroup consists of five major clades, with P. melisellensis as its most basal taxon. Monophyly of P. tauricus sensu stricto is not supported, with one of the subspecies (P. t. ionicus) displaying great genetic diversity (hidden diversity or cryptic species). It comprises five, geographically distinct, subclades with genetic distances on the species level. Species delimitation approaches revealed nine species within the P. tauricus species subgroup (P. melisellensis, P. gaigeae, P. milensis, and six in the P. tauricus complex), underlining the necessity of taxonomic re-evaluation. We thus synonymize some previously recognized subspecies in this subgroup, elevate P. t. tauricus and P. g. gaigeae to the species level and suggest a distinct Albanian-Greek clade, provisionally named as the P. ionicus species complex. The latter clade comprises five unconfirmed candidate species that call for comprehensive studies in the future.
塔乌里克壁蜥的单系物种亚群分布在巴尔干半岛的西部和南部，包括四个种，其种间和种内的系统发育关系尚未解决且未被研究。利用来自两个线粒体基因和三个核基因的序列数据，并对一个广泛的数据集应用多种系统发育方法和物种界定方法，我们重建了巴尔干半岛壁蜥属蜥蜴的系统发育，并重新研究了塔乌里克壁蜥物种亚群的分类地位。多位点分析表明，上述亚群由五个主要分支组成，其中梅利塞尔壁蜥是最基部的分类单元。狭义的塔乌里克壁蜥的单系性不被支持，其中一个亚种（塔乌里克壁蜥伊奥尼亚亚种）表现出很大的遗传多样性（隐藏多样性或隐存种）。它包括五个在地理上不同的亚分支，其遗传距离处于物种水平。物种界定方法揭示了塔乌里克壁蜥物种亚群内有九个物种（梅利塞尔壁蜥、盖氏壁蜥、米氏壁蜥，以及塔乌里克壁蜥复合体中的六个物种），强调了分类重新评估的必要性。因此，我们将该亚群中一些先前认可的亚种进行了同义化处理，将塔乌里克壁蜥指名亚种和盖氏壁蜥盖氏亚种提升到物种水平，并提出一个独特的阿尔巴尼亚 - 希腊分支，暂命名为伊奥尼亚壁蜥物种复合体。后一个分支包括五个未经证实的候选物种，未来需要进行全面研究。
