Isoperla namata Frison

Distribution. 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.
