Diagnosis. Egg as described in Szczytko & Kondratieff (2015, figs. 61.11‒61.14) from the Uwharrie Mountains in North Carolina. In addition, the egg has a biconcave profile with a lateral ridge ( Figs. 13‒14 ) opposite of the profile with the cross-shaped ridges ( Fig. 15 ) and the anterior pole is slightly concave ( Fig. 16 ).

Comments. This is a new Alabama state record. This species is common in mid-order streams draining the Talladega Mountain region. Isoperla zuelligi should be found in the intervening states of Georgia and South Carolina.
