Diagnosis.

Adult males of Nannaria monsdomia   sp. nov. are distinct from other Nannaria   and the nearby N. scutellaria   , based on the following combination of characters. Gonopods. Gonopodal acropodite slightly curving medially basal to apex, not straight basal to apex as in N. scutellaria   . Distal zone much reduced, rounded, with small, lobed lateral flange (Fig. 57A View Figure 57 , red triangle)-not simple as in N. hardeni   sp. nov., or bent at 90° with pronounced medial flange as in N. scutellaria   . Telopodite basal zone height > 2/3 length of acropodite, not < 1/3 length as in N. scutellaria   . Prefemur with large, laminate prefemoral process, curving medially, crossing acropodite and expanding before tip, not straight, acicular as in N. hardeni   sp. nov., or curving laterally as in N. scutellaria   . Prefemoral process length greater than height of telopodite basal zone, not subequal as in N. hardeni   sp. nov. Prefemoral spine widely separated from prefemoral process (Fig. 57A View Figure 57 , red arrow) and rounded, not sharp or tooth-like as in N. hardeni   sp. nov., or lacking as in N. scutellaria   . Color. Tergites with bright orange paranotal spots and faint orange stripes (Fig. 58 View Figure 58 ). Dark brown background. Dorsum of collum smooth with orange margin.

Measurements.

♂ holotype (VTEC, MPE02188): BL = 30.7, CW = 4.2, IW = 2.2, ISW = 0.9, B11W = 4.2, B11H = 3.1; ♀ paratype (VTEC, MPE02187): BL = 33.5, CW = 4.1, IW = 2.5, ISW = 1.1, B11W = 5.3, B11H = 3.9.

Variation.

No known variation.

Distribution.

Known only from the type locality, Suppl. material 7; Fig. 126 View Figure 126 . Distribution area: N/A; status: MRE.

Ecology.

Individuals of N. monsdomia   sp. nov. were collected from a mesic hardwood forest dominated by beech, maple, magnolia, pawpaw, and poison ivy. All specimens were found under 1-4 cm of hardpacked soil at the edge of boulders near a dried up, rocky stream.

Etymology.

The specific epithet is an arbitrary combination of letters from the Latin mons, meaning mountain, and domus, meaning house, which refers to the type locality House Mountain State Natural Area. It is to be treated as a noun in apposition.

Type locality.

United States, Tennessee, Knox County, Mascot, House Mountain State Natural Area, along dried up stream beside Hogskin Rd., 36.1032°N, - 83.7642°W.
