N2 - The skeleton and musculature of male genitalia were studied in species of a model butterfly group (subtribe Polyommatina, Lycaenidae). In total, we analyzed 45 species of the tribe Polyommatini most of which were previously used in the molecular phylogenetic study (Talavera et al., 2013). The studied morphological characters were mapped on the molecular trees, which allowed us to reveal trends of morphological changes and to estimate the age of their origin. As a result, chronology of evolution of skeleton and musculature traits was established. It was shown that periods of slow morphological evolution alternated in the subtribe Polyommatina with those of a high rate of origin of new traits. For example, topography of the intravalvar muscles has not changed for 26 MY preserving their initial fan-shaped attachment. The evolution of intravalvar muscles started 10 MYA, proceeded slowly during the first 5 MY, and then accelerated during the last 5 MY resulting in the extensive splitting of the musculature in most
