Journal of Insect Science: Vol. 13 | Article 72 Grubbs et al. Distribution patterns of Ohio stoneflies, with an emphasis on rare and uncommon species Scott A. Grubbs1a*, Massimo Pessimo2b, R.

All 9 Nearctic fami- http://jinsectscience.oxfordjournals.org/ lies are represented. Over 90% of the fauna exhibit a combination of broad Nearctic-widespread, eastern Nearctic-widespread, Appalachian, and eastern Nearctic-unglaciated distributions. In con- trast, only 2 species display a central Nearctic-Prairie distribution. Seven species of Perlidae are likely no longer present (Acroneuria evoluta Klapálek, A. perplexa Frison, Attaneuria ruralis (Hagen), and Neoperla mainensis Banks) or have experienced marked range reductions (Acro- neuria abnormis (Newman), A. frisoni Stark and Brown, and A. filicis Frison). Another nearly 31% of the fauna (32 species) are rare, uncommon, or have highly-limited distributions within the by guest on August 12, 2015 state. Twelve of these species have Appalachian distributions, and an additional 8 have eastern Nearctic-unglaciated distributions. The distributional status for each of the 32 rare/uncommon species is discussed. Keywords: Midwestern, Nearctic, range reduction Correspondence: a
