Variations of main characters in the genus Sphinogontus fieb., distributed in Mongolia

In the study, we have considered all possible variations of main characters, such as colour pattern of inner side of hind femora, intercalary vein of the elytra, branches of the radial sector (RS) of the elytra, in each of three populations of Sphingonotus elegans Mistch., S. beybienkoi Mistch., S. gobicus Chogs species. We have identified 7 variations of bands on the inner side of the hind femura, as well as a number of stable characteristics that have classification significance for these three species. The study has shown new variations of the main characters not mentioned in the original description of S. gobicus Chogs.
