First records of three weevil species (Coleoptera, Curculionoidea) from Siberia

This study presents the first records of three weevil species from Siberia, specifically, from the Kurgan Oblast, Russia. The identified species include Aspidapion aeneum (Fabricius, 1775), Mecaspis alternans (Hellwig, 1795), and Polydrusus confluens Stephens, 1831. Notably, Polydrusus confluens represents a new addition to the Asian fauna. These findings highlight the limited understanding of the weevil fauna in the southern part of the West Siberian Plain, an area where numerous species of Western Palearctic origin have been recorded at the easternmost edge of their range.
