Material examined.

Holotype: United States - Virginia • ♂; Wise County, Osborn Rock, FR 238; 36.8949°N, - 82.5902°W; elev. 1112 m; 17 Aug. 2006; hand collected; P. Marek & C. Spruill leg.; VTEC MMC0035.

Paratype: United States - Virginia • 1 ♀; same collection data as holotype; VTEC MMC0021 • 2 ♀♀; same collection data as holotype; VMNH MMC0027, 32. For detailed collection data see Suppl. material 7 .

Diagnosis.

Adult males of Nannaria spruilli sp. nov. are distinct from other Nannaria and the nearby N. aenigma, based on the following combination of characters: Gonopods. Gonopodal acropodite straight, curving medially at nearly 90° angle at apex, not gently curving or with medial swelling as in N. blackmountainensis sp. nov. Acropodite tip blunt with small, lobed lateral flange (Fig. 85C, red arrow), not with large, hooked lateral flange as in N. blackmountainensis sp. nov., or thin, sinuous tip as in N. aenigma . Height of telopodite basal zone> 1/2 length of acropodite, not < ½ length as in N. blackmountainensis sp. nov., or ca. 1/6 length as in N. aenigma . Prefemur with straight, acicular prefemoral process and reduced prefemoral spine (Fig. 85C, red triangle). Color. Color in life unknown.

Measurements.

♂ holotype (VTEC, MMC0035): BL = 29.9, CW = 3.8, IW = 2.1, ISW = 0.8, B11W = 5.1, B11H = 3.1; ♀ paratype (VMNH, MMC0027; head taken for DNA): BL = N/A, CW = 4.1, IW = N/A, ISW = N/A, B11W = 5.4, B11H = 3.7.

Variation.

No known variation.

Distribution.

Known only from the type locality (Virginia: Wise County, Suppl. material 7; Fig. 126). Distribution area: N/A; status: MRE.

Ecology.

Individuals of N. spruilli sp. nov. were collected from mesic broadleaved forests from underneath deciduous leaf litter. Nannaria spruilli sp. nov. was encountered co-occurring with a Mullerian mimicry ring composed of the xystodesmid species Apheloria polychroma, Brachoria cedra Keeton, 1959, and Brachoria insolita Keeton, 1959 (Marek and Bond 2009).

Etymology.

This species was named after its co-collector, Chad Spruill. The specific name is a genitive noun derived as a patronym.

Type locality.

United States, Virginia, Wise County, Osborn Rock, FR238; 36.8949°N, - 82.5902°W.
