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). This species is presumed extirpated from Illinois ( DeWalt and Grubbs 2011) and Ohio ( DeWalt et al. 2012). 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 ).
