Diagnosis.

Adult males of N. domestica are distinct from other Nannaria and the nearby N. blackmountainensis sp. nov. based on the following combination of characters: Gonopods. Gonopodal acropodite semi-circular, gently curving dorsomedially throughout, not with abrupt 90° angle after apex as in N. laminata or pre-apex swelling as in N. blackmountainensis sp. nov. Acropodite tip with small, triangular lateral flange (Fig. 11A , red triangle), not hooked as in N. blackmountainensis sp. nov. and not simple, lacking flange as in N. laminata . Tip terminating in sharp, caudally-directed point, not blunt, rectangular as in N. blackmountainensis sp. nov. Height of telopodite basal zone ca. 1/4 length of acropodite, not> 1/3 length of acropodite as in N. laminata and ca. 1/2 length as in N. blackmountainensis sp. nov. Prefemoral process large, laminate and serpentine with prefemoral spine reduced to small, rectangular shelf, not fused with prefemoral process as in N. blackmountainensis sp. nov. Color. Tergites with orange paranotal spots (Fig. 12 ). Dark brown background. Dorsum of collum smooth with orange margin.

Measurements.

♂ (VTEC, MPE00305): BL = 28.6, CW = 3.3, IW = 1.8, ISW = 0.8, B11W = 4.2, B11H = 2.7; ♀ (VTEC, MPE00312): BL = 31.9, CW = 3.9, IW = 1.8, ISW = 0.9, B11W = 4.9, B11H = 3.5.

Variation.

No known variation

Distribution.

Known only from Blowing Rock, Watauga County, North Carolina (Suppl. material 7; Fig. 126 ). Distribution area: N/A; status: MRE.

Ecology.

Individuals of N. domestica have been collected from under leaf litter in mesic broadleaved forests composed of oak, maple, and rhododendron.

Etymology.

Shelley (1975) gives no etymology for this name, however it is reasonable to assume that the name refers to the type specimen being collected from a residence.

Type locality.

United States, North Carolina, Watauga County, Blowing Rock, from the yard of residence on Goforth Road, 0.5 miles north U.S. highway 321.

Notes.

In the original paper, Shelley (1975: 186) examined and designated the holotype male (NCSM 1007) collected by himself on October 16, 1971.
