Diagnosis.

Adult males of Nannaria solenas   sp. nov. are distinct from other Nannaria   and the sympatric N. asta   sp. nov. and N. aenigma   , based on the following combination of characters: Gonopods. Gonopodal acropodite straight, not gently curving throughout as in N. asta   sp. nov. or N. aenigma   . Distal zone short, rectangular, bent medially at 90° angle with acropodite with slight cephalically-directed upturn at terminal edge (Fig. 82A View Figure 82 , red arrow), not rounded, directed caudally with lateral flange as in N. asta   sp. nov., or sinuous as in N. aenigma   . Acropodite simple with slight swelling on inner margin but lacking dimple on outer margin as in N. asta   sp. nov., or hooked lateral flange as in N. aenigma   . Prefemur with long, acicular prefemoral process, not stout as in N. asta   sp. nov., or laterally curving as in N. aenigma   . Prefemoral spine pronounced and tooth-like (Fig. 82C View Figure 82 , red triangle), not cephalically-curving as in N. asta   sp. nov. or lacking as in N. aenigma   . Telopodite basal zone simple, ca. 1/2 length of acropodite, not with lateral bulge, < ½ length of acropodite as in N. asta   sp. nov., or < 1/6 length of acropodite as in N. aenigma   . Color. Tergites with orange paranotal spots (Fig. 83 View Figure 83 ). Black background. Dorsum of collum smooth with orange and white margin.

Measurements.

♂ holotype (VTEC, MPE00128): BL = 30.8, CW = 4.1, IW = 2.1, ISW = 1.0, B11W = 5.0, B11H = 3.3; ♀ paratype ( VMNH, MPE00140): BL = 34.7, CW = 4.3, IW = 2.5, ISW = 1.1, B11W = 5.5, B11H = 3.1.

Variation.

Individuals from Crawfish Valley, Wythe County, Virginia, have reduced, shelf-like prefemoral spines (Fig. 84 View Figure 84 , red triangle).

Distribution.

Known from southwestern Virginia and southeastern West Virginia, with an individual from central West Virginia (West Virginia: Fayette, Mercer, and Summers counties; Virginia: Bland, Giles, Russell, Tazewell, and Wythe counties, Suppl. material 7; Fig. 126 View Figure 126 ). Distribution area: 3,009 km2; status: SRE.

Ecology.

Individuals of Nannaria solenas   sp. nov. have been collected from mesic hardwood forests, dominated by oak, maple, and pine. Specimens from Crawfish Valley were collected at night while walking on top of grass in an overgrown road.

Etymology.

This species is named after its type locality, Pipestem Resort State Park in West Virginia. The specific name is a noun in apposition derived from the Greek solínas, meaning pipe.

Type locality.

United States, West Virginia, Summers County, Pipestem Resort State Park, path to lake, ca. 12 km northeast of Athens, 37.5278°N, - 80.9889°W.
