Here I present notes on two new species recently found in the upper freshwater portion of the Hudson River, Floridobia winkleyi (Pilsbry, 1912) and Valvata lewisi (Currier, 1868) collected during a study in 2008 (Coote and Strayer 2009, Strayer et al. in prep). Floridobia winkleyi is not only a new record for the river but its presence represents a significant expansion of its limited range from Connecticut to Maine (Smith 1994) and brings into question previously identified specimens attributed to Marstonia lustrica (Pilsbry, 1890) in the river. The other new record is the New York state listed species Valvata lewisi. All species found during the 2008 survey are reported here as well.
