Observations document a new beetle species in Russia, suggesting potential range expansion in East Asia.
The genus Trypoxylus Minck, 1920 and the species T. dichotomus (Linnaeus, 1771) are recorded for Russia for the first time. The material was collected in the southwestern part of Primorskii krai and in the southern part of Kunashir Island. The distribution range of the species is considered in East Asia and in the border areas with Russia. Prospects of further range expansion of T. dichotomus are evaluated for the southern Far East of Russia.
