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 View Figure 85 , 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 View Figure 85 , red triangle). Color. Color in life unknown.
♂ 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.
No known variation.
Known only from the type locality (Virginia: Wise County, Suppl. material 7; Fig. 126 View Figure 126 ). Distribution area: N/A; status: MRE.
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).
This species was named after its co-collector, Chad Spruill. The specific name is a genitive noun derived as a patronym.
