The karyotype of Polyommatus (Agrodiaetus) eriwanensis Forster, 1960 from the type locality ("Eriwan" [Yerevan, Armenia]) and other localities in Armenia was investigated. The number of chromosomal elements (bivalents+ multivalents) observed in male meiosis I was found to vary from 29 to 34. In individuals with n = 34, all observed elements were represented by bivalents. In other specimens, heterozygosity for different number of chromosomal fusions resulted in multivalent formation at MI stage and consequently in a lower number of recognizable chromosomal elements. We show that all karyotype peculiarities of P. (A.) interjectus de Lesse, 1960 (n = 29-32) from Turkey are similar to those in . The butterflies of these taxa have allopatric distribution and can be considered as conspecific.
对1960年发现于模式产地（“埃里温”[亚美尼亚首都埃里温]）及亚美尼亚其他地区的埃里温蓝灰蝶（Polyommatus (Agrodiaetus) eriwanensis Forster）的核型进行了研究。在雄性减数分裂I中观察到的染色体元件（二价体+多价体）数量在29到34之间变化。在n = 34的个体中，所有观察到的元件均由二价体代表。在其他标本中，不同数量染色体融合的杂合性导致在减数分裂中期I形成多价体，从而使可识别的染色体元件数量减少。我们发现，1960年发现于土耳其的居间蓝灰蝶（P. (A.) interjectus de Lesse）（n = 29 - 32）的所有核型特征与埃里温蓝灰蝶相似。这些分类群的蝴蝶具有异域分布，可被视为同种。
