USA : AR, IL, IN, MO, OH, OK ( DeWalt et al. 2015 ) Material examined. Adair Co. , Casey Creek , 5 km NE Knifely , 36.2656 , -85.1511 , 13 April 2013 , S.A. Grubbs & J.M. Yates , 1♂ , 1♀ ( WKUC ); Taylor Co. , Robinson Creek , 24 km NE Elk Horn , 37.3285 , - 85.2666 , 13 April 2013 , S.A. Grubbs & J.M. Yates , 8♂ , 7♀ ( WKUC ) . Comments . The recent revision of eastern Nearctic Isoperla by Szczytko & Kondratieff (2015) did not include this species from Kentucky . These two series definitively fit the concept of I. namata . The ranges of I. namata and I. kirchneri overlap in central Kentucky .
