Diagnosis.

Adult males of Nannaria mcelroyorum   sp. nov. are distinct from other Nannaria   and the nearby N. shenandoa   , based on the following combination of characters: Gonopods. Gonopodal acropodite gently curving medially throughout, not straight as in N. shenandoa   . Acropodite gradually tapering towards tip, with small lobed medial flange (Fig. 26A View Figure 26 , red triangle), lacking swollen medial area as in N. serpens   sp. nov. Tip directed medially, rounded and simple, not with folds, grooves, flanges as in N. shenandoa   . Distal zone greatly reduced, not enlarged and curving caudolaterally as in N. shenandoa   . Prefemur with thin, sinuous, acicular prefemoral process, not curved, saber-like as in N. shenandoa   . Prefemoral spine small, medially directed, with secondary hump proximal to acropodite base (Fig. 26C View Figure 26 , red arrow), not enlarged, cephalically directed as in N. serpens   sp. nov., or lacking as in N. shenandoa   . Telopodite basal zone height ca. 1/2 length of acropodite, not > 1/2 length of acropodite as in N. serpens   sp. nov. or ca. 1/5 length as in N. shenandoa   . Color. Tergites with light orange paranotal spots and faint orange stripes (Fig. 27 View Figure 27 ). Light brown background. Dorsum of collum smooth with orange margin.

Measurements.

♂ paratype (VTEC, MPE03116; holotype too damaged for measurement): BL = 33.9, CW = 4.7, IW = 2.3, ISW = 0.9, B11W = 5.4, B11H = 3.6; ♀ paratype (VTEC, MPE03117): BL = 33.2, CW = 4.4, IW = 2.5, ISW = 1.3, B11W = 5.9, B11H = 4.3.

Variation.

Individuals of N. mcelroyorum   sp. nov. from the Boone County, West Virginia site have prefemoral processes ca. 2/3 the length of those of the holotype.

Distribution.

Known from a linear area in western West Virginia and Eastern Kentucky (Kentucky: Boyd County; West Virginia: Boone and Wayne counties, Suppl. material 7; Fig. 127 View Figure 127 ). Distribution area: 105 km2; status: MRE.

Ecology.

Individuals of N. mcelroyorum   sp. nov. were collected from mesic deciduous forests dominated by oak, maple, laurel, and some pine, often under 1-2 cm soil.

Etymology.

This species is named for Clint, Justin, Travis, and Griffin McElroy from Huntington, West Virginia, who provided endless hours of emotional support to JCM and DAH during field collections through their podcasts, 'The Adventure Zone’ and 'My Brother, My Brother, and Me’. The specific name is a plural genitive derived as a patronym.

Type locality.

United States, West Virginia, Wayne County, Barboursville, Beech Fork State Park, Lost Trail near Moxley Branch Campground, 38.3047°N, - 82.3512°W.
