Fauna of Curculionoidea (Coleoptera) of the Republic of Mordovia

The known fauna of the Republic of Mordovia comprises 506 species of Curculionoidea from six families: Anthribidae (8), Attelabidae (15), Brentidae (81), Cimberididae (1), Curculionidae (400), and Nemonychidae (1). The checklist includes 36 species newly recorded for the region. For each species, the number of plots and specimens is provided. The article also discusses the zoogeographical structure of the regional Curculionoidea fauna, demonstrating its complex nature. Against the background of the predominance of widespread species with Trans-Palaearctic and Western-Central Palaearctic ranges, a significant portion of the fauna is represented by the Western Palaearctic complex (96 species, 19%), along with smaller assemblages of species characterized by predominantly Central Palaearctic (14 species) and Central-Eastern Palaearctic distributions (16 species), as well as eight amphipalaearctic forms. In terms of zonal affiliation, nearly half of the fauna consists of polyzonal species. The Subboreal and Southern Boreal-Subboreal complexes are also strongly represented (together comprising 44%), with a smaller group of boreal forms (35 species; 7%).
