Distal zone short, bent medially forming 130° angle with acropodite (Fig. 50). Telopodite basal zone ca. 1/3 length of acropodite, not <1/3 as in  N. fowleriand  N. shenandoa. Acropodite tip and distal zone simple, rectangular, blunt, <1/8 length of acropodite, not large, curving with flange as in  N. shenandoa. Prefemoral process arising from top of prefemoral spine (Fig. 50A, red arrow), paralleling medial curve of acropodite, not arising from bottom of prefemoral spine as in  N. fowleri, or curving laterally as in  N. shenandoa. Prefemoral spine large, curving cephalically, not stout, tooth-like as in  N. fowleri.  Color.Tergites with orange paranotal spots (Fig. 51). Black background. Dorsum of collum smooth with orange margin.   Figure 50.  Nannaria tasskelsoaesp. nov. holotype ♂ (VTEC, SPC000710) left gonopod Aanterior view; red arrow indicates pronounced, curving prefemoral spine Bmedial view Cposterior view. Scale bar: 0.5 mm.   Figure 51.  Nannaria tasskelsoaesp. nov. non-type ♂ (VTEC, MPE04021) coloration. Scale bar: 4.0 mm.  Measurements. ♂ holotype (VTEC, SPC000710): BL = 30.5, CW = 3.9, IW = 2.4, ISW = 0.9, B11W = 5.0, B11H = 3.3; ♀ paratype (VTEC, SPC000712): BL = 34.4, CW = 4.3, IW = 2.2, ISW = 1.1, B11W = 5.3, B11H, 4.1.  Variation. The most notable variation amongst individuals of  N. tasskelsoaesp. nov. is found in the southern range of the species'distribution. One specimen from Greenville, West Virginia (NAN0040) has a sudden lateral curve in the tip of its prefemoral process, forming a cat-claw like bend, while another specimen from near Forest Hill, West Virginia (NAN0149) has a laminate medial flange that is distal to the acropodite apex. Additional variation between populations is minimal, and is primarily found in the degree to which the prefemoral process parallels the acropodite and the size of the prefemoral spine.  Distribution.   Nannaria tasskelsoaesp. nov. has a linear distribution running the length of the eastern edge of West Virginia (West Virginia: Randolph, Nicholas, Greenbrier, Monroe, Pocahontas, Summers, and Tucker counties; Suppl. material 7; Fig. 127). Distribution area: 3,623 km2; status: SRE.  Ecology. Specimens of  N. tasskelsoaesp. nov. were collected from mesic hardwood forests composed of beech, black cherry, oak, sugar maple, tuliptree, and yellow birch. Several specimens were found on hillsides, including those from Summit Lake Campground which were active on top of leaf litter at night.  Etymology. This species is named after Dr. Tass Kelso, systematic botanist. Dr. Kelso was mentor to the discoverer of this species, Charity Hall. The specific name is a genitive noun derived as a matronym.  Type locality. United States, West Virginia, Greenbrier Co., Monongahela National Forest, Summit Lake Campground; 38.2490°N, - 80.4437°W. 3071355427 2005-07-20 P.
