Neoperla mainensis Banks, 1948 Notes Neoperla mainensis is commonly referred to as the Maine Stone (Stark et al. 2012). This species is known only from historical records from Ontario (Pelee Point of Lake Erie) and in the USA in Illinois, Maine, New York, and Ohio (DeWalt et al. 2024).

Our record is based on Cornell University specimens collected on June 11, 1919 (Fig. 33) at 146 m asl (Fig. 34) from the Roeliff Jansen Kill, a tributary to the Hudson River in Level IV Ecoregion Taconic Foothills (58 x) (Fig. 36 d).
