Alloperla stipitata Surdick, 2004:21 View in CoL . Holotype male (USNM), small stream, north of Sherando Lake , Augusta Co., Virginia (examined)

Distribution. USA: VA ( DeWalt et al. 2018)

Material examined. USA, Virginia, Bland Co., Kumberling Creek, Sulphur Springs Creek , 18 May 2017, B.C Kondratieff & C. Verdone, 3 males ( CSUC) ; Botetourt Co., spring fed stream, Blue Ridge Parkway , 31 May 2016, B.C Kondratieff & C. Verdone, 1 male ( CSUC) ; Greene Co., Fork Hollow, Ranger Station , nr. Simmons Gap , Shenandoah National Park , 3 June 2016, B.C Kondratieff & C. Verdone, 3 males ( CSUC) ; Montgomery Co., Poverty Creek, Poverty Hollow , Rt 708, 0.5 miles from Rt 460, 17 June 1978, 1 male, B.C. Kondratieff ( CHNC – A. biserrata paratype) .

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 View FIGURES 23–30 ). 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 View FIGURES 23–30 ). 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 View FIGURES 23–30 ). The apical notch is subtriangular and extends anteriorly and ventrally as a groove between paired, serrated apical margins ( Figs. 25–28 View FIGURES 23–30 ); 5 distinct teeth are present ( Figs. 29–30 View FIGURES 23–30 ); the serrated apex is linear ventrally ( Figs. 29–30 View FIGURES 23–30 ). In lateral view the epiproct is broadest medially ( Fig. 29 View FIGURES 23–30 ). 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 View FIGURES 23–30 ). 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 View FIGURES 23–30 ).

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.

Comments. Alloperla stipitata is known only from Virginia ( Fig. 40 View FIGURE 39–40 ), with many recent locality records provided by Dr. Boris Kondratieff ( CSUIC) as by-catch specimens to three species studied in detail in Verdone & Kondratieff (2017). This species may be distributed further northward along the Blue Ridge Mountains through Maryland to southern Pennsylvania.
