description: <i>Sweltsa pocahontas</i> Kirchner &amp; Kondratieff (Figs. 31-35) <i>Sweltsa pocahontas</i> Kirchner &amp; Kondratieff, 1988:233. Holotype &amp;male; (United States National Museum), West Virginia, Pocahontas Co., Monongahela National Forest, Right Fork of Tea Creek <b>Material examined. MARYLAND: Garrett Co., Spring to Elk Lick Run, Westernport Rd, 1.7 mi upstream Savage River confluence, 17 May 1995, S.A. Grubbs, 2&amp;female;, 3 larvae (WKU)</b>. <b>WEST VIRGINIA: Pocahontas Co.:</b> North Fork Cherry River, Hwy 39/53, 17 May 1993, B.C. Kondratieff, R. F. Kirchner, 8&amp;male;, 1&amp;female;, 2 pharate larvae (BCK). <b>Mature larva.</b> Body length 8.5-9.0 mm. General color brown, without distinctive pigment pattern except underlying adult features in pharate individuals. Pronotum bearing ca. 16 anterolateral setae near margin and ca. 17 posterolateral setae (Fig. 31); both setal rows extend near median suture. Mesonotum bearing ca. 10 long outer marginal setae and an irregular submarginal row of ca. 6 setae beyond basal grouping (Fig. 32). Metanotum with numerous intercalary setae on wingpad and an outer marginal row of mostly short thick setae extending to apex of wingpad; a few inner marginal setae on meso and metanota. Fore femora with a sparse grouping of several fringe setae and a few long thick setae along dorsal margin (Fig. 33); additional thick setae on femoral surface and along ventral margin; fore tibiae fringed along outer margin and bearing three long outer setae and ca. 9 thick inner setae. Abdominal tergum 8 with posterior fringe incomplete mesally; lateral intercalary cluster includes ca. 12 setae (Fig. 34). Cerci with ca. 18 segments; long dorsal setae in apical segmental whorls about as long as 1.75 segments (Fig. 35). <b>Comments.</b> As Surdick (2004) noted, this species is restricted to the Ridge and Valley Province and Allegheny Plateau of West Virginia and Maryland. It is sympatric with <i>S. lateralis</i> and may also be sympatric with <i>S. palearata</i>. Larvae of <i>S. lateralis</i> and <i>S. pocahontas</i> generally occur in headwater seeps and rheocrenes. The two species can be distinguished on the basis of dorsal cercal setation length which in <i>S. pocahontas</i> is about as long as 1.5 cercal segments whereas in <i>S. lateralis</i> these setae are typically as long as two segments.Also the larvae of <i>S. palearata</i> may be distinguished from similar <i>S. hoffmani</i> by the absence of intercalary setae on tergum 10. See additional comments above for <i>S. lateralis</i>.
