Isoperla gibbsae Harper, 1971

was reported from Maryland in Duffield & Nelson (1990) ( Fig. 26 ) but not included as occurring in the state by Szczytko & Kondratieff (2015). This species is retained in the Maryland state list pending verification. Szczytko & Kondratieff (2015) similarly noted that the West Virginia record of I. gibbsae (Kirchner 1978) requires verification.
