First records of two remarkable Coleoptera species Cucujus cinnaberinus and Metoecus paradoxus (Coleoptera: Cucujidae, Rhipiphoridae) from the Republic of Karelia (Russia)

Viable populations of two remarkable Coleoptera species -Cucujus cinnaberinus (Cucujidae) and Metoecus paradoxus (Rhipiphoridae) are reported for the first time from the Republic of Karelia (Russia). Cucujus cinnaberinus is a threatened species in northern Europe while Metoecus paradoxus is a widespread Palaearctic species actively dispersing northwards. Both species were found in the nature protected areas by the local staff. This evidences the importance of such territories for preserving and monitoring the populations of rare and poorly known species.
