Material examined.

United States - North Carolina • 1 ♂; Alleghany County, 10 mi W Spart, 0.1 mi NE on 1308 jct 1303; 36.4987°N, - 81.3080°W; 17 May 1980; R. Shelley, MSM leg.; NCSM NAN0496. For detailed collection data see Suppl. material 7 .

Hypothesized placement.

Nannaria “Peden” specimens are hypothesized to be closely related to Nannaria tasskelsoae sp. nov. based on the following combination of gonopodal characters: Telopodite prefemoral process arising medially from pronounced, tooth-like prefemoral spine (Fig. 122A , red arrow). Prefemoral process paralleling acropodite throughout majority of length. Nannaria “Peden” specimens differ from N. tasskelsoae sp. nov. based on the following combination of gonopodal characters: Acropodite tip serpentine, resembling snake prepared to strike, directed dorsally (Fig. 122B , red triangle), not directed medially as in N. tasskelsoae sp. nov.
