Nowe gatunki ryjkowców (Coleoptera: Curculionoidea) w Kotlinie Biebrzańskiej. / New species of weevils (Coleoptera: Curculionoidea) in the Biebrza Basin.

Records of 24 Curculionoidea species new for the Biebrza Basin in Northeastern Poland, including the Biebrza National Park and its buffer zone, are provided as a result of field studies in 2021-2022. Three more weevil species, unique or rare in Poland, were rediscovered in the Biebrza Basin after nearly 20 years, including Anthonomus rubripes GYLLENHAL previously thought to be extinct. The fauna of the Biebrza Basin comprises currently 505 species of Curculionoidea (Scolytinae excluded), being among the richest documented for protected areas in Northeastern Poland. Noteworthy and alarming is a great decrease in abundance of practically all hygrophilous weevil species observed in the Lower Biebrza, compared to results of previous surveys conducted in 1999-2004.
