The introduction of invasive species is a leading cause of biodiversity loss in aquatic ecosystems. Non-native organisms that enter these systems disrupt local communities by competing for resources and altering established ecological interactions. In the Volga-Caspian basin, the rate of species introductions has increased significantly due to growing anthropogenic pressure. This study reports a new polychaete species for the Volga-Caspian basin, identified during benthic community monitoring in the Volga River (Tsarev channel) in the summer of 2024. Zoobenthos samples were collected using a Van Veen grab with a sampling area of 0.025 m?. The species Laonome xeprovala, previously recorded in the Baltic, North, Black, and Azov Sea basins, was found at a water temperature of 27.0°C and a depth of 2.0 m. The substrate consisted of sand mixed with clay and macrophyte detritus. Two unmet specimens of polychaetes with a maximum length of 1.2 cm, were recorded.
