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.

核型重新研究并未证实克里米亚多眼虫（Agrodiaetus）达摩克利斯复合体（鳞翅目，狼科）中存在两种隐秘物种和种间杂交。

来自安加尔斯基山口（克里米亚）的蓝蝴蝶的核型，以前被认为是 Polyommatus (Agrodiaetus) 海神 (Herrich-Schäffer, 1851)，现在被重新检查。在所有19个研究个体中，我们发现单倍体染色体数n = 26，其中包括7对相对较大的染色体和19对相对较小的染色体。根据染色体数目和核型结构，研究种群与来自克里米亚山脉东部的P. (A.) damocles krymaeus (Sheljuzhko, 1928)没有区别。这一结果并没有证实先前提出的假设，根据该假设，（1）两个形态相似但核学不同的物种，P.（A.）poseidon和P.（A.）damocles krymaeus，在克里米亚同域出现；（2）安加尔斯基山口的这些类群之间存在杂交。因此，克里米亚地区只有三个 Agrodiaetus Hübner 亚属（1822 年）被可靠地确定：P. (A.) damone pljushtchi Lukhtanov & Budashkin, 1993、P. (A.) damocles krymaeus (Sheljuzhko, 1928) 和 P. (A.) damone pljushtchi Lukhtanov & Budashkin, 1993。 (A.) ripartii budashkini Kolev & de Prins, 1995。
