| Abstract | Adults and nymphs of Stenonema meririvulanum sp. are described. Adults are characterized by large dark spiracular dots, gray margined hind wings, and very long banded caudal filaments. Nymphs are characterized by 'V'-shaped pale areas on abdominal terga 7-9, posterolateral spines on abdominal segments 7-9, and an unmarked abdominal venter. The species has been collected from small prisine streams in the Appalachian Mountains. |
