First record of Dorcatoma janssoni Buche & Lundberg, 2002 (Coleoptera: Ptinidae) from Russia

The deathwatch beetle Dorcatoma janssoni Büche & Lundberg, 2002 (Coleoptera: Ptinidae) is recorded from Russia for the first time. Specimens were collected in the European part of Russia (Ryazan Oblast, Oka State Nature Biosphere Reserve) using window traps mounted 140–160 cm above ground level on dead wood of Populus tremula. The study site represents a mixed forest dominated by P. tremula with associated species Pinus sylvestris, Quercus robur, and Corylus avellana. The collection yielded 13 additional species of xylophagous and mycetophagous beetles occurring syntopically with D. janssoni. Diagnostic morphological characters are illustrated with photographs of the male antenna and genitalia.
