Newly described species at first glance, due to relatively regularly convex body, not very distinctly deplanate anterior angles of the pronotum and lack of typical deplanations on sides of the pronotum, as well as the relatively normally developed elytral intervals with macrosetae only on the sides and before apex, seems to be more similar to the genus
. Besides, large distance between mesocoxae, typical shape of meso-metaventral plate, denticulate clypeus and typical punctation of head definitely place newly described species in the genus

Additional body composites that allow it to be distinguished from other species are shape of meso-metaventral plate and shape of scutellum – both of which are distinctive and unique among different species of the genus. In any case, the two features mentioned need to be studied in the future in different manuscript, as they are not easy to determine (unique shapes of concavities before apex of meso-metaventral plates, unique clustering of scutellum punctation, etc.), and also – with this features it will probably be easier in the future to determine the relationship of affinities between species and possible new genera (as
