The ant Santschi, 1925 is native to the Iberian Peninsula. This species, as well as other species from the complex, could form supercolonies that make these species potentially invasive and could give rise to pests. Recently a mature colony from this species has been found in the Isle of Wight (United Kingdom). Mitogenomes have been used to study the taxonomy, biogeography and genetics of species, improving the development of strategies against pest invasion. However, the number of available mitogenomes from the subfamily Dolichoderinae is still scarce and only two of these mitogenomes belong to species. Herein, the complete mitogenome of is presented in order to increase the molecular information of the genus. The mitogenome, retrieved by Next-Generation Sequencing data, is 15,715 bp in length. It contains the typical set of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNAs and the A + T-rich control region. Comparisons of the mitogenome with other dolichoderine mitogenomes revealed the existence of four gene rearrangements in relation with the ancestral insect mitogenome. One of these rearrangements, involving the -, and genes, was found in most of the analyzed ant mitogenomes. Probably this rearrangement was an ancestral or plesiomorphic character in Formicidae. Interestingly, another rearrangement that affects to , and genes was found only in species. This change could be a synapomorphic character for the genus , and could be used as a phylogenetic marker. Additionally, a phylogenetic analysis was performed using the protein-coding gene sequences from available Dolichoderinae mitogenomes, as well as mitogenomes from representative species from other Formicidae subfamilies. Results support the monophyletic nature of the genus placing it within the same clade as the rest of Dolichoderinae species.
蚁属 Santschi，1925 年原产于伊比利亚半岛。该物种以及来自复杂的其他物种，可能形成超级殖民地，使这些物种具有潜在的入侵性，并可能产生害虫。最近在怀特岛（英国）发现了一个来自该物种的成熟殖民地。线粒体基因组已被用于研究物种的分类学、生物地理学和遗传学，从而改进针对害虫入侵的策略的制定。然而，来自 Dolichoderinae 亚科的可用线粒体基因组数量仍然很少，只有两个属于 物种。本文介绍了 的完整线粒体基因组，以增加该属的分子信息。通过下一代测序数据检索到的 线粒体基因组长 15715bp，包含典型的 13 个蛋白质编码基因、2 个核糖体 RNA 基因、22 个转移 RNA 和富含 A + T 的控制区。将 线粒体基因组与其他 Dolichoderinae 线粒体基因组进行比较，发现了与祖先昆虫线粒体基因组相关的四个基因重排。这些重排中的一个，涉及-、-和-基因，在大多数分析的蚂蚁线粒体基因组中都有发现。可能这种重排是在 Formicidae 中是一个祖先或原始特征。有趣的是，另一个影响到-、-和-基因的重排仅在 物种中发现。这种变化可能是属的一个独特特征，并且可以用作系统发育标记。此外，还使用来自可用的 Dolichoderinae 线粒体基因组以及来自其他 Formicidae 亚科代表物种的蛋白质编码基因序列进行了系统发育分析。结果支持属的单系性，将其置于与其余 Dolichoderinae 物种相同的分支中。
