Tomares hairstreaks comprise about 10 species distributed from Europe and North Africa to Central Asia. The taxonomy of the genus is hampered by the absence of diagnostic characters by which specimens can be unambiguously assigned to species. Our investigation of morphology and DNA barcode variations within and between Tomares species shows that while well-defined species (T. ballus, T. mauritanicus, T. callimachus, T. desinens and T. fedtschenkoi) diverge, poorly characterized taxa (T. nogelii, T. nesimachus, T. dobrogensis, T. romanovi and T. telemachus) show very little to no differentiation in mtDNA. We reinstate Tomares callimachus spp. hafis (Kollar, 1849) as a valid subspecies (stat. rev.) and propose taxa telemachus Zhdanko, 2000 and uighurica Koçak, Seven & Kemal, 2000 as synonyms of T. romanovi and T. nogelii nogelii respectively (syn. nov.). We relegate Polyommatus epiphania Boisduval, 1848, recently revived as a valid subspecies of T. callimachus, back to synonymy under the latter, and reconsider the status of T. nogelii dobrogensis (Caradja, 1895) in the light of new molecular data. We use a nuclear gene (EF-1α) in addition to COI barcodes to reconstruct the phylogeny of the group.

Tomares hairstreaks 的分子分类学（鳞翅目、Lycaenidae、Theclinae）

Tomares hairstreaks 大约有 10 种，分布从欧洲和北非到中亚。由于缺乏诊断特征，标本可以明确地分配给物种，因此该属的分类受到阻碍。我们对 Tomares 物种内部和之间的形态学和 DNA 条形码变异的调查表明，虽然定义明确的物种（T. ballus、T. mauritanicus、T. callimachus、T. desinens 和 T. fedtschenkoi）存在分歧，但特征较差的分类群（T. nogelii 、T. nesimachus、T. dobrogensis、T. romanovi 和 T.telemachus）在 mtDNA 中显示出很少甚至没有差异。我们恢复了 Tomares callimachus spp。hafis (Kollar, 1849) 作为有效亚种 (stat. rev.) 并提议将分类群 telemachus Zhdanko, 2000 和 uighurica Koçak, Seven & Kemal, 2000 作为 T. romanovi 和 T. nogelii nogelii (syn. nov.)。我们将 Polyommatus epiphania Boisduval, 1848, 最近作为 T. callimachus 的一个有效亚种复活，回到后者的同义词，并根据新的分子数据重新考虑 T. nogelii dobrogensis (Caradja, 1895) 的地位。除了 COI 条形码之外，我们还使用核基因 (EF-1α) 来重建该组的系统发育。
