The karyotype of the blue butterflies from the Angarskiy Pass (Crimea), previously attributed to Polyommatus (Agrodiaetus) poseidon (Herrich-Schäffer, 1851), was re-examined. In all 19 studied individuals, we found the haploid chromosome number n = 26, including 7 pairs of relatively large and 19 pairs of relatively small chromosomes. According to the chromosome number and karyotype structure, the studied population does not differ from P. (A.) damocles krymaeus (Sheljuzhko, 1928) from the eastern part of the Crimean Mountains. This result does not confirm the previously formulated hypotheses, according to which (1) two morphologically similar but karyologically different species, P. (A.) poseidon and P. (A.) damocles krymaeus, occur sympatrically in the Crimea and (2) there is hybridization between these taxa on the Angarskiy Pass. Thus, only three species of the subgenus Agrodiaetus Hübner, 1822 have been reliably established for the Crimea: P. (A.) damone pljushtchi Lukhtanov & Budashkin, 1993, P. (A.) damocles krymaeus (Sheljuzhko, 1928) and P. (A.) ripartii budashkini Kolev & de Prins, 1995.
对之前被归为波塞冬蓝蝶（Polyommatus (Agrodiaetus) poseidon，赫里希 - 谢弗，1851年）、来自安加尔斯基山口（克里米亚）的蓝蝶的核型进行了重新研究。在所有19个被研究个体中，我们发现单倍体染色体数n = 26，包括7对相对较大的染色体和19对相对较小的染色体。根据染色体数量和核型结构，所研究的种群与来自克里米亚山脉东部的克里米亚波塞冬蓝蝶（P. (A.) damocles krymaeus，谢尔朱日科，1928年）没有差异。这一结果并未证实之前提出的假设，即（1）形态相似但核型不同的两个物种，波塞冬蓝蝶（P. (A.) poseidon）和克里米亚波塞冬蓝蝶（P. (A.) damocles krymaeus）在克里米亚同域分布，以及（2）在安加尔斯基山口这些分类单元之间存在杂交。因此，对于克里米亚，仅可靠地确定了1822年胡伯纳亚属阿格罗迪亚埃特斯（Agrodiaetus）的三个物种：1993年的普氏波塞冬蓝蝶（P. (A.) damone pljushtchi，卢赫塔诺夫和布达什金）、1928年的克里米亚波塞冬蓝蝶（P. (A.) damocles krymaeus，谢尔朱日科）和1995年的布氏波塞冬蓝蝶（P. (A.) ripartii budashkini，科列夫和德普林斯）。
