Diagnosis.

Adult males of Nannaria komela   sp. nov. are distinct from other Nannaria   and the nearby N. wilsoni   , based on the following combination of characters: Gonopods. Gonopodal acropodite semi-circular, curving dorsomedially throughout, with appearance of slight swelling before apex in posterior view (Fig. 13C View Figure 13 , red arrow), not with corkscrew before apex as in N. wilsoni   . Tip simple, rounded, curving dorsally. Tip not sharp, with small triangular lateral flange as in N. domestica   , or with laminate expansion and tooth-like lateral flange as in N. wilsoni   . Height of telopodite basal zone reduced, ca. 1/4 length of acropodite, not ca. 1/6 as in N. wilsoni   . Prefemoral process serpentine, curving ventrally. Prefemoral process not laminate as in N. domestica   , or long, curving medially as in N. wilsoni   . Prefemoral spine reduced and fused with prefemoral process, forming basal ridge (Fig. 13C View Figure 13 , red triangle), not separate as in N. domestica   . Color. Tergites with orange paranotal spots (Fig. 14 View Figure 14 ). Black background. Dorsum of collum smooth with orange margin.

Measurements.

♂ holotype (VTEC, MPE03523): BL = 28.1, CW = 3.6, IW = 2.2, ISW = 0.8, B11W = 4.6, B11H = 3.0; ♀ paratype (VTEC, MPE03699): BL = 33.3, CW = 3.8, IW = 2.0, ISW = 1.0, B11W = 5.0, B11H = 3.3.

Variation.

The specimen from Beartown Mountain ( VMNH NAN0141) has a slightly less serpentine prefemoral process, and a more pronounced prefemoral spine.

Distribution.

Known from southwestern Virginia and northwestern North Carolina (Virginia: Carroll and Russell counties; North Carolina: Surry County, Suppl. material 7; Fig. 126 View Figure 126 ). Distribution area: 70 km2; status: MRE.

Ecology.

Individuals of Nannaria komela   sp. nov. have been collected from mesic deciduous forests dominated by oak, maple, tuliptree, and rhododendron. They are often found under 1-2 cm moist soil on hillsides.

Etymology.

The specific epithet is an arbitrary combination of letters from the Greek kome, meaning ‘village,’ and melon, meaning ‘sheep,’ which refers to the town of Lambsburg, Virginia nearby to the type locality. It is to be treated as a noun in apposition.

Type locality.

United States, Virginia, Carroll County, Lambsburg, Lambsburg Rd., Hawks State Forest, hillside above Turkey Creek, 36.6062°N, - 80.7720°W.
