Material examined.

United States - Virginia • 1 ♂; Scott County, woods off Rt. 72, ca 3 mi NE of Dungannon, 500 ft. beyond entrance to Hanging Rock USFS Rec Area ; 36.8589°N, - 82.4340°W; 14 Nov. 2007; R. Hoffman leg.; VMNH NAN0360. For detailed collection data see Suppl. material 7 .

Hypothesized placement.

Nannaria "Hanging Rock" specimens are hypothesized to be closely related to Nannaria “Bina” based on the following combination of gonopod characters: With predominantly straight acropodite and short distal zone. Prefemoral process arising medially from pronounced, tooth-like prefemoral spine. Nannaria "Hanging Rock" can be separated from “Bina” based on the following combination of characters: Acropodite tip pointed, not rounded as in “Bina”. Acropodite with pointed lateral flange near apex (Fig. 118A , red arrow), not rounded as in “Bina”. Prefemoral process curving towards but not crossing acropodite in anterior view.
