Diagnosis. Szczytko & Kondratieff (2015) placed I. sandbergi in the I. similis ( Hagen, 1861) Group with I. bellona Banks, 1911 , I. cherokee Szczytko and Kondratieff, 2015 , I. distincta Nelson, 1976 , I. major Nelson and Kondratieff, 1983 , I. similis , and I. starki Szczytko and Kondratieff, 2015 . The eggs of I. bellona and I. distincta remain undescribed. The combination of a concave profile and lack of a collar easily distinguishes the eggs of I. sandbergi from I. cherokee , I. major , I. similis , and I. starki . The eggs of I. major and I. similis are round in crosssection, possess a low raised collar, and lack a concavity ( Szczytko & Kondratieff 2015, figs. 29.7, 51.15). The eggs of I. cherokee and I. starki have a concave profile but possess either a low, buttonlike collar ( I. cherokee ; Szczytko & Kondratieff 2015, Figs. 7.24‒7.25 View Figs ) or a distinct, elevated collar ( I. starki ; Szczytko & Kondratieff 2015, Fig. 55.21).
Comments. This species appears to be the most common headwater Isoperla in the Talladega Mountain region (Sheldon & Grubbs unpublished data).
