Material examined.

United States - Virginia • 1 ♂; Russell County, Clinch Mtn., 1 mile SE of Repass; 36.9786°N, - 81.7926°W; elev. 1128 m; 5 July 1962; R. Hoffman leg.; VMNH NAN0130 • 1 ♂; Russell County, along Laurel Bed Lake, SW of Saltville , Clinch Mountain ; 36.9558°N, - 81.8137°W; 26 Apr. 1975; D. Ogle leg.; VMNH NAN0143. For detailed collection data see Suppl. material 7 .

Hypothesized placement.

Nannaria “Repass” specimens are hypothesized to be closely related to Nannaria botrydium sp. nov. based on close geographic proximity and the following combination of gonopodal characters: Acropodite thin, gently curving medially. Acropodite tip with small lateral flange (Fig. 123B , red arrow). Prefemoral process bending medially at midpoint. Nannaria “Repass” differs from N. botrydium sp. nov. based on the following gonopodal characters: Acropodite tip bending dorsally with small, triangular medial flange (Fig. 123B , red triangle), not bending caudally as in N. botrydium sp. nov. Prefemoral process bending medially at midpoint to a lesser degree than as in N. botrydium sp. nov.
