The groups of red-bellied lizards had a small distribution area in the Pontic zone. The several studies performed on these lizard groups are based on taxonomy and systematics. Although there were several taxonomic or systematic researches on some species of this group, the phylogeographical pattern and species disturbing boundaries of this group is still not clear. In the present study, we aimed to resolve the taxonomic and phylogenetic relationships of the red-bellied lizards in Turkey, based on two combined mitochondrial gene fragments and one protein-coding nuclear gene (rag1). Also, we evaluated ecological niches differentiations among red-bellied lizard groups. The mitochondrial DNA genes were found to be highly polymorphic in this group. One hundred and one variable nucleotide sites were detected on the combined gene sequences. According to phylogenetic trees based on the maximum likelihood (ML) and Bayesian inference (BI), the red-bellied lizards group have three species groups; Darevskia parvula, D. adjarica and unnamed Darevskia sp. (candidate species for Darevskia genus). This situation was supported by high bootstrap and posterior probability values in the trees of mitochondrial DNA gene fragments. However, no genetic variation was detected according to nuclear DNA (rag1) sequence. Because the species groups have no overlaps in terms of their ecological niches, ecological niche modelling (ENM) results revealed differences among the groups of D. parvula, D. adjarica, and unnamed Darevskia sp. Besides, we detected no geographical overlaps among three species groups, since there were geographical isolation zones among the species groups of red-bellied lizard.

红腹蜥蜴群在蓬蒂奇地区分布很小。对这些蜥蜴群进行的几项研究是基于分类学和系统的。尽管对该组中的某些物种进行了一些分类学或系统研究，但该组的系统地理模式和物种干扰边界仍不清楚。在本研究中，我们旨在基于两个结合的线粒体基因片段和一个蛋白质编码核基因（rag1）来解决土耳其红腹蜥蜴的分类学和系统发育关系。）。此外，我们评估了红腹蜥蜴群体之间的生态位分化。发现线粒体DNA基因在该组中高度多态。在组合的基因序列上检测到一百零一个可变核苷酸位点。根据基于最大似然（ML）和贝叶斯推断（BI）的系统发育树，红腹蜥蜴组分为三个物种组。Darevskia parvula，D. adjarica和未命名的Darevskia sp。（达里夫斯基属的候选物种）。线粒体DNA基因片段树中的高自举和后验概率值支持了这种情况。然而，根据核DNA（rag1）未检测到遗传变异。） 顺序。由于物种组在生态位方面没有重叠，因此生态位建模（ENM）结果揭示了D. parvula，D. adjarica和未命名Darevskia sp。组之间的差异。此外，由于红腹蜥蜴的物种组之间存在地理隔离区，因此我们没有发现三个物种组之间的地理重叠。
