description: <i>Allocapnia granulata</i> Claassen <i>Capnella granulata</i> Claassen, 1924. Holotype male, Johnstown, New York <i>Allocapnia granulata</i>: Ross &amp; Ricker, 1971. Mississippi record <b>Distribution.</b>AL, AR, DC, IA, IL, IN, KS, KY, LA, MB, MD, MI, MN, MO, MS, NJ, NY, OH, OK, ON, PA, PQ, TN, TX, VA, WI, WV (Stark &amp; Baumann 2006). The published Mississippi record is from a single femalespecimen housed in the Illinois Natural History Survey, and collected in Marshall County in 1941 (Ross &amp; Ricker 1971; Stark 1979). Several efforts to recollect the species from streams in the Potts Camp area have been unsuccessful but populations were discoveredat four sites in Noxubee County and Kemper County during December 2006. <b>Mississippi collection data. (Fig. 10). Kemper Co.,</b> Shy Hammock Creek, Hwy 16, 32 <b>°</b> 49’ 85.8” N, 88 <b>°</b> 23’ 74.7” W, 28 December 2006, M. Hicks, 1 &amp;male;, 1 &amp;female;; Samelocation, 12 January 2007, B.

Hicks and M. Howarter, 7 &amp;male;, 2 &amp;female;. <b>Male epiproct.</b> Epiproct dorsal arm conspicuously angled near midlength, becoming slightly wider subapically and forming a more or less paddle shaped apical section (Fig. 11). Apical half of dorsal arm bears numerous, short, spiny projections (Fig.13); projections become smaller and more sparsely distributed toward apical section base. In dorsal aspect a median, narrow, shallow groove divides apical section of dorsal arm (Figs.11, 13). In lateral aspect, dorsal arm slightly inflated and densely spinose near tip, ventral arm slightly recurved and smooth at apex (Fig.12). <i>Allocapnia granulata</i> <b>Male tergal process.</b> Tergum 8 process deeply notched in dorsal aspect, forming a pair of elongate knobs in V&amp;hyphen; shaped pattern (Fig.14); knobs armed with scale&amp;hyphen; like tubercles and an additional small, hairy scaleless knob is located behind larger scaled knobs. In lateral aspect, scaled knobs are low at anterior margin and are slanted upward toward projecting, hairy, posterior knobs (Fig.15). <b>Female subgenital plate.</b> Abdominalsternum 8 bears a slightly projecting median plate with low mesal point and base constricted by small lateral notches (Figs.16, 60). Sterna 7 and 8 completely separated by membrane.
