Subsequent molecular phylogenetic studies confirmed that Glabroculus does not belong within Polyommatus, and it is treated as a distinct genus. Elviria Zhdanko, 1994, listed as a synonym in the article, was also included by some authors within Polyommatus before the molecular evidence clarified its placement.
