Terry, 1 male (BYU) .</p><p>Amended description – Male. Tergum 10 divided mesally by epiproct and reduced cowl into two hemitergal lobes; lobes bearing dense matting of long setae (Figs. 1–2). Epiproct length (L) 240 µm, maximum width (MW) 47 µm, L:MW ratio = 5.1. In dorsal view the epiproct is widest in basal ⅓, tapering anteriorly to a slightly mediallyexpanded apex (Figs. 1–2); dorsal surface covered by dense matting of long hairs in medial ⅓; apical ⅓ is entirely bare; in basal ⅓ there is only a medial line of hairs (Figs. 1–4). The apical notch is narrowly triangular in shape and extends anteriorly and ventrally as a groove between paired, serrated apical margins; 5–6 distinct teeth are present (Figs. 5–8, 10, 12). In lateral view the epiproct is thin basally and gradually broadens apically (Figs. 9, 11); matting is absent basally and along the ventral margins; long hairs deflected laterally are present in medial ½ (Figs. 9, 11); shorter hairs on the apical, serrated portion are present as a medial band (Figs. 10, 12). The stem length is approximately 2X the length of the apical serrated portion (Figs. 9, 11). Overall, the SEM of the specimens studied herein from Maryland and Virginia are essentially identical in shape and matting patterns to the Virginia population studied in Willett &amp; Stark (2009, their figs. 55–60).</p><p>Adult males (and females) are pale yellow in alcohol. The head lacks any darkened markings. The pronotum has a continuous pale yellow margin and the medial 75% of the segment is only slightly darker.</p><p>Comments. Reexamination of a specimen designated as a paratype produced an unexpected result. The male collected from “…confluence of Straley Branch with Poverty Creek off County Route 708, Montgomery Co., Virginia, Jefferson National Forest, altitude 630 m, 17 June 1978 ” (Nelson &amp; Kondratieff 1980, see pg. 802) is actually of A. stipitata . Alloperla biserrata occupies a relatively narrow latitudinal and longitudinal band in the southern and central Appalachian Mountains (Fig. 39). Amongst the four members of the Alloperla nanina Group, this species is the only one known northward to Maryland and southern Pennsylvania.</p></div>	https://treatment.plazi.org/id/03C587D9BC76E472CFB1852B808DFE78	Public Domain	No known copyright restrictions apply.

Tergum 10 divided mesally by epiproct and reduced cowl into two hemitergal lobes; lobes bearing dense matting of long setae (Figs. 13–15). Epiproct length (L) 125 µm, maximum width (MW) 40 µm, L:MW ratio = 3.2. In dorsal view the epiproct is widest in basal ⅓, tapering anteriorly and distally. The entire dorsal surface is bare (Figs. 14–17). The apical notch is narrowly triangular and extends anteriorly and ventrally as a groove between paired, serrated apical margins (Figs. 15–18); 10 distinct teeth are present (Figs. 17, 21–22); the serrated apex is arcuate ventrally (Figs. 19–22). The epiproct stem is secondarily reduced and nearly absent; the serrated portion comprises the entire lateral profile (Figs. 19–22). Dense hair matting is also absent laterally; a sparse group of long hairs are present in medial ⅓ (Figs. 20–22).</p><p>The adults of A. nanina are unusual amongst eastern Nearctic Alloperla species in that the pronotum has a charcoal gray pigmentation within the medial 75% of the segment (the entire margin is pale yellow in color), the mesonotal and metanotal scutellar margins are darkly pigmented, and the abdomen has darkened medial and lateral stripes (Surdick 2004, Grubbs &amp; Singai 2018, their fig. 15).</p><p>Comments. The taxonomic histories of A. banksi Frison, 1942 and A. nanina are intertwined. As was customary at the time, the original Banks (1911) description lacked illustrations. He indicated that individuals were small, the pronotum was darkly pigmented, plus this species was then only known from the type locality in western North Carolina. Although Needham &amp; Claassen (1925) attempted to provide the first illustrations of the male of A. nanina (their plate 20, fig. 3), this unintentionally represented an undescribed species. They noted variability at the tip of the epiproct, namely as “…sharply-pointed and smooth…” or “…bilobed…” and added that this did not justify differentiation into separate species. Several additional locality records were also added from New York and Nova Scotia. Soon thereafter, Frison (1935) mistakenly described A. lodgei as new from Gatlinburg, Tennessee, providing several illustrations, especially his plates XIII (his fig. 25) and XIV (his fig. 36) that now are easily recognized as A. nanina . Frison (1942) recognized the Needham &amp; Claassen (1925) mistake, described A. banksi from New York, and synonymized A. lodgei under A. nanina . Surdick (2004) has likewise provided a brief taxonomic history. The New York listing in DeWalt et al. (2018) now pertains to A. banksi . Alloperla nanina appears to be a species endemic mainly to the southern Appalachian Highlands region (Fig. 39).</p></div>	https://treatment.plazi.org/id/03C587D9BC73E471CFB1836B80F3FE78	Public Domain	No known copyright restrictions apply.

Kondratieff (CHNC – A. biserrata paratype) .</p><p>Amended description – Male. Tergum 10 divided mesally by epiproct and reduced cowl into two hemitergal lobes; lobes bearing dense matting of long setae (Figs. 23–24). Epiproct length (L) 150 µm, maximum width (MW) 62 µm, L:MW ratio = 2.4. In dorsal view the epiproct is widest in medial ½, tapering both anteriorly and distally (Figs. 23–24). The dorsal surface is covered by a dense matting of long hairs except for the anterior 1/5, which is entirely bare (Figs. 23–26). The apical notch is subtriangular and extends anteriorly and ventrally as a groove between paired, serrated apical margins (Figs. 25–28); 5 distinct teeth are present (Figs. 29–30); the serrated apex is linear ventrally (Figs. 29–30). In lateral view the epiproct is broadest medially (Fig. 29). The stem is slightly longer than the serrated apex and covered by a dense matting of long hairs except for a narrow bare band laterally near the hinge (Fig. 29). The lateral portion of the serrated apex is bare except for a single line of 5–6 hairs plus a few additional accessory hairs (Fig. 30).</p><p>Adult males (and females) are pale yellow in alcohol. The head lacks any darkened markings. The pronotum has a continuous pale yellow margin and the medial 75% of the segment is only slightly darker.</p><p>Comments. Alloperla stipitata is known only from Virginia (Fig. 40), with many recent locality records provided by Dr. Boris Kondratieff (CSUIC) as by-catch specimens to three species studied in detail in Verdone &amp; Kondratieff (2017). This species may be distributed further northward along the Blue Ridge Mountains through Maryland to southern Pennsylvania.</p></div>	https://treatment.plazi.org/id/03C587D9BC70E471CFB1836B811BF99F	Public Domain	No known copyright restrictions apply.

His collecting efforts during the 1990s helped form the backbone of an Atlas on Ohio Plecoptera (DeWalt et al. 2016) and are likewise critical for the current development on an Atlas on West Virginia Plecoptera . The common name “Clark Sallfly” is proposed for this species (Stark et al. 2012).</p><p>Diagnosis. Alloperla clarki sp. nov. is readily differentiated from A. nanina by the presence of the epiproct stem. The stem is distinct on A. clarki sp. nov. (Fig. 37) and secondarily reduced for A. nanina (Fig. 21). This is easily deciphered with standard light microscopy. Although seen most easily on SEM micrographs, the secondary loss of dense hair matting on both the epiproct stem and apical serrated margin of A. nanina (Figs. 19–22) is easily contrasted from A. clarki sp. nov. (Figs. 32, 37). For A. clarki sp. nov., the only portion of the epiproct lacking matting is dorsoapical surface, the ventral serrated margins, and thin lateral areas near the hinge (Figs. 37–38).</p><p>Alloperla clarki sp. nov. can also be differentiated from A. biserrata by characteristics of the epiproct. For A. biserrata the ratio of total epiproct length to maximum width is 5.1 (Fig. 11) compared to 3.1 for A. clarki sp. nov. (Fig. 37). In lateral view the epiproct stem of A. biserrata has a narrower profile basally (Fig. 9) compared to A. clarki sp. nov. (Fig. 37). In addition, A. biserrata has a larger glabrous area near the epiproct hinge (Figs. 9, 11) compared to A. clarki sp. nov. (Fig. 37).</p><p>Alloperla clarki sp. nov. is morphologically similar to A. stipitata but there are three diagnostic, albeit subtle, differences on the epiproct. First, 5-6 distinct teeth are present on the apical serrated margin of A. stipitata (Figs. 28–30). This is contrasted from the 8-9 teeth present on A. clarki sp. nov. (Figs. 35–36, 38). Second, the ventral serrated margin of A. stipitata is positioned essentially along one linear, ventral plane (Figs. 29–30) compared to the ventral arcuate shape of A. clarki sp. nov. (Figs. 37–38). Third, there is a difference in the total length to maximum width ratio (2.4: A. stipitata vs. 3.1: A. clarki sp. nov.) between the two species.</p><p>Remarks. The type locality and the two paratype sites are positioned in southern West Virginia and adjacent southwestern Virginia in EPA Level III Ecoregion 67 (Ridge and Valley; Fig. 40). Twelve and nine Alloperla species are now known from Virginia and West Virginia, respectively (DeWalt et al. 2018). A collecting effort in early June 2018 to the two West Virginia streams noted above and the vicinity in general failed to produce fresh material of A. clarki sp. nov. for additional study.</p></div>	https://treatment.plazi.org/id/03C587D9BC70E47ECFB187F08116F984	Public Domain	No known copyright restrictions apply.
