Chromosomal and molecular analyses of rapidly evolving organisms such as Polyommatus Latreille, 1804 blue butterflies are essential for understanding their taxonomy and evolutionary history, and the studies of populations from their type localities are crucially important for resolving problems of nomenclature and species identity. Here we present data on the topotypical population of the blue butterfly species described as Lycaena damone var. cyanea Staudinger, 1899. This taxon was described from Khankendi (Nagorno-Karabakh, Caucasus), and rediscovered at the type locality for the first time since it was collected there in 1869. The specimens were found on dry stony meadows with a predominance of Onobrychis radiata Bieberstein, 1810, on upper border of oak forests. Their haploid chromosome number (n) was established as n = 17. Chromosomal and mitochondrial DNA barcode analyses of the studied samples from type-locality provided an opportunity for the critical taxonomic re-examination of Caucasian species of the subgenus Agrodiaetus Hübner, 1822 of the genus Polyommatus Latreille, 1804. The obtained data support the interpretation of the P. (A.) cyaneus (Staudinger, 1899) and P. (A.) carmon (Herrich-Schäffer, 1851) as two different, not closely related species complexes as previously hypothesized by Hugo de Lesse. On the contrary, the treatment by Walter Forster who considered these taxa as two groups of conspecific populations was not supported by our data.

Polyommatus (Agrodiaetus) cyaneus (Staudinger, 1899) 的核型和 DNA 条形码从其类型位置：对 Polyommatus 蓝蝴蝶（鳞翅目，Lycaenidae）分类学和进化研究的意义

对快速进化的生物体（如 Polyommatus Latreille、1804 蓝蝴蝶）的染色体和分子分析对于了解它们的分类学和进化历史至关重要，而对其类型地区的种群的研究对于解决命名和物种身份问题至关重要。在这里，我们提供了关于被描述为 Lycaena damone var 的蓝蝴蝶物种的拓扑种群数据。cyanea Staudinger, 1899。这个分类群是从 Khankendi（高加索地区的纳戈尔诺-卡拉巴赫）描述的，自 1869 年在该模式产地采集以来首次在该类型产地重新发现。这些标本是在以 Onobrychis 为主的干燥石质草地上发现的radiata Bieberstein，1810 年，位于橡树林的上边界。它们的单倍体染色体数 (n) 确定为 n = 17。对来自类型位置的研究样本进行染色体和线粒体 DNA 条形码分析，为对多毛虫属的 Agrodiaetus Hübner 亚属的高加索物种进行关键的分类学重新检查提供了机会，1822 年，Polyommatus Latreille 属，1804 年。获得的数据支持解释P. (A.) cyaneus (Staudinger, 1899) 和 P. (A.) carmon (Herrich-Schäffer, 1851) 作为 Hugo de Lesse 先前假设的两个不同的、不密切相关的物种复合体。相反，我们的数据不支持将这些分类群视为两组同种种群的 Walter Forster 的处理。1822 年 Polyommatus Latreille 属，1804 年。获得的数据支持将 P. (A.) cyaneus (Staudinger, 1899) 和 P. (A.) carmon (Herrich-Schäffer, 1851) 解释为两个不同的，不紧密的Hugo de Lesse 先前假设的相关物种复合体。相反，我们的数据不支持将这些分类群视为两组同种种群的 Walter Forster 的处理。1822 年 Polyommatus Latreille 属，1804 年。获得的数据支持将 P.
