The non-native oligochaete Ripistes parasita (Schmidt) (Annelida: Clitellata: Naididae) has previously been reported from the northeastern United States and Mississippi. The objective of this study was to provide information regarding the spread of the invasive oligochaete within the past 32 years. We examined benthic invertebrate data from various biomonitoring projects conducted in several eastern states. Results show a significant range extension for this species.
