Adult males of Nannaria caverna sp. nov. are distinct from other Nannaria and nearby N. shenandoa , based on the following combination of characters: Gonopods. Gonopodal acropodite linear, bent medially forming 130° angle with telopodite basal zone bent medially at tip, not continually curving throughout as N. serpens sp. nov. and N. shenandoa . Tip simple, rectangular, without laminate flanges as in N. shenandoa . Telopodite basal zone tall, > 1/2 length of acropodite, not < 1/2 as in N. serpens sp. nov. and N. shenandoa . Prefemur with sinuous, ventrally directed prefemoral process, bent at a 90° angle, arising from large, pronounced prefemoral spine (Fig. 24B View Figure 24 , red arrow), not directed cephalically as in N. serpens sp. nov., or curving laterally as in N. shenandoa . Color. Tergites with light orange paranotal spots (Fig. 25 View Figure 25 ). Light grey background, likely due to teneral condition of specimens. Collum smooth with orange margin.
♂ holotype (VTEC, MPE03139): BL = 24.7, CW = 3.8, IW = 2.5, ISW = 0.8, B11W = 4.2, B11H = 2.9. ♀ paratype ( VMNH, MPE03159): BL = 25.7, CW = 3.2, IW = 2.2, ISW = 1.2, B11W = 4.0, B11H = 2.9.
No known variation.
Known only from the type locality (Kentucky: Carter Caves State Park; Suppl. material 7; Fig. 127 View Figure 127 ). Distribution area: N/A; status: MRE.
Individuals of N. caverna sp. nov. were collected as they emerged from hardpacked soil on the edge of a creek running through Carter Caves State Park. The surrounding forest was made up of hardwood trees and rhododendron thickets.
This species is named for its type locality. The specific name is a noun in apposition from the Latin caverna for cave.
