Sawfly Fauna (Hymenoptera: Symphyta) in the Mordovia State Nature Reserve (Central Russia)

Protected areas are biodiversity hotspots of the world. Knowledge of their overall biodiversity is essential for nature conservation. Sawflies are an integral part of terrestrial ecosystems; being phytophages, they play a significant role in the processing of primary production. The aim of the research was to study the biodiversity of sawflies in the Mordovian Reserve. The research was carried out in 2008, 2009 and 2012-2019 on the territory of the Mordovia State Nature Reserve (Republic of Mordovia, Central part of European Russia). The article provides information on records of 169 species of sawflies of 9 families in the Mordovia State Nature Reserve. The annotated list includes 103 new species for the reserve, of which 1 species (Dineura parcivalvis) is listed for the European part of Russia for the first time, and 3 species are specified for the first time for the Central part of European Russia (Arge beckeri, Rhogogaster genistae, Tenthredo amurica).
