Contribution to the knowledge of Corylophidae (Coleoptera: Cucujoidea) of Poland

As a result of a faunistic survey of the family Corylophidae (Coleoptera: Cucujoidea) in Poland, distributions of 16 species are reviewed and new findings are reported. Clypastraea reitteri Bowestead found in the Kozienice Forest (Malopolska Upland) and Orthoperus nikitskyi Bowestead from Bystre ad Baligrod (Bieszczady Mts.) are reported for the first time to occur in Poland. The latter species has been known from the holotype female only, collected in environs of Moscow, and the Polish specimen is the first known male of O. nikitskyi. Arthrolips nana (Mulsant & Rey) is recorded for the first time from the Pomeranian Lake District, Masurian Lake District, Wielkopolska-Kujawy Lowland, and Mazovian Lowland; A. obscura (Sahlberg) from the Trzebnickie Hills; A. picea (Comolli) from the Masurian Lake District, Wielkopolska-Kujawy Lowland, Maiopolska Upland and Roztocze; Sericoderus lateralis (Gyllenhal) from the Pomeranian Lake District and Trzebnickie Hills; Orthoperus atomus (Gyllenhal) from the Wielkopolska-Kujawy Lowland and Swietokrzyskie Mts.; O. nigrescens Stephens from the Malopolska Upland, Lower Silesia and Swietokrzyskie Mts.; and O. rogeri Kraatz from the Masurian Lake District and Sandomierska Lowland. The occurrence of O. atomarius (Heer) in Poland requires verification. An updated checklist of Central European species of Corylophidae is provided, supplemented with taxa possible to find in Poland, including expansive species and those frequently introduced to neighboring countries.
