Abstract

Temnothorax unifasciatus (Latreille, 1798) is a widely distributed pan‐European species from the Iberian Peninsula to the Caucasus. This taxon's relatively high morphological variability prompts the taxonomists of earlier times and today to mention the morphologically different elements at specific or subspecific ranks. This paper aims to understand the population structure and genetic diversity within this lineage via integrative taxonomy, incorporating molecular phylogenetics, species delimitation analyses and multivariate analyses of continuous morphometric data from across the geographic range of the T. unifasciatus complex. Phylogenetic analyses yielded incongruent trees. The genealogical diversity index (gdi) and the confirmatory analyses on morphological data found only weak, ambiguous delimitations within the unifasciatus complex. The most highly supported scenario splits T. brackoi from the remaining unifasciatus complex with ambiguous support (gdi = 0.56). This scenario is supported by multivariate morphometry with 100% accuracy in classification success. Instead, our results suggest complex morphological and genetic population structuring within the broad range of T. unifasciatus. Therefore, we confirm the validity of two species, T. brackoi Salata & Borowiec, 2019 and T. unifasciatus (Latreille, 1798), and propose five new junior synonymies, T. cordieri (Bondroit, 1918) syn. nov., T. tauricus (Ruzsky, 1902) syn. nov., T. berlandi (Bondroit, 1918) syn. nov., T. unifasciatus staegeri (Bondroit, 1918) syn. nov., T. tuberum ciscaucasicus (Arnol'di, 1977) syn. nov. with the latter. To achieve maximal taxonomic stability, we designated a lectotype for Temnothorax unifasciatus (Latreille, 1798).

综合分类法揭示了欧洲Temnothorax unifasciatus复合体（膜翅目：蚁科）中膨胀的生物多样性

Temnothorax unifasciatus（Latreille，1798 年）是一种广泛分布于伊比利亚半岛至高加索地区的泛欧物种。该分类群的形态变异性相对较高，这促使早期和现在的分类学家将形态上不同的元素划分为特异或亚特异等级。本文旨在通过综合分类学，结合分子系统学、物种划界分析以及对 T. unifasciatus 复合体整个地理范围内的连续形态计量数据进行多元分析，了解这一品系的种群结构和遗传多样性。系统进化分析得出了不一致的树。系谱多样性指数（gdi）和形态学数据的确证分析只发现了单翼蝠复合体内部微弱而模糊的分界。支持率最高的方案是将 T. brackoi 从剩余的 unifasciatus 复合体中分离出来，但支持率不明确（gdi = 0.56）。多变量形态测量法支持这种情况，分类准确率为 100%。相反，我们的研究结果表明，在 T. unifasciatus 的广泛分布区内，存在着复杂的形态和遗传种群结构。因此，我们确认了两个物种：T. brackoi Salata & Borowiec, 2019 和 T. unifasciatus (Latreille, 1798) 的有效性，并提出了五个新的小异名：T. cordieri (Bondroit, 1918) syn、T. tauricus (Ruzsky, 1902) syn. nov.、T. berlandi (Bondroit, 1918) syn. nov.、T. unifasciatus staegeri (Bondroit, 1918) syn. nov.、T. tuberum ciscaucasicus (Arnol'di, 1977) syn. nov.与后者同属。为了达到最大的分类稳定性，我们为 Temnothorax unifasciatus (Latreille, 1798) 指定了一个讲座模式。

期刊介绍： Zoologica Scripta publishes papers in animal systematics and phylogeny, i.e. studies of evolutionary relationships among taxa, and the origin and evolution of biological diversity. Papers can also deal with ecological interactions and geographic distributions (phylogeography) if the results are placed in a wider phylogenetic/systematic/evolutionary context. Zoologica Scripta encourages papers on the development of methods for all aspects of phylogenetic inference and biological nomenclature/classification. Articles published in Zoologica Scripta must be original and present either theoretical or empirical studies of interest to a broad audience in systematics and phylogeny. Purely taxonomic papers, like species descriptions without being placed in a wider systematic/phylogenetic context, will not be considered.
