Material examined.

United States - West Virginia • 1 ♂; Mercer County, Athens ; 37.4222°N, - 81.0163°W; 27 Mar. 1966; W. Shear leg.; VMNH NAN0051 • 1 ♂; Summers County, Lick Creek ; 37.4845°N, - 80.9114°W; 15 May 1956; W. Shear leg.; VMNH, NAN0052. For detailed collection data see Suppl. material 7 .

Hypothesized placement.

Nannaria “Attica” specimens are hypothesized to be closely related to N. hippopotamus sp. nov. based on the following combination of gonopodal characters: Acropodite straight with sudden bend at tip. Acropodite with lateral flange (Fig. 115A , red arrow). Nannaria “Attica” specimens differ from N. hippopotamus sp. nov. based on the following combination of gonopodal characters: Acropodite lateral flange small and triangular (Fig. 115A , red arrow), not with prominent lobed lateral flange as in N. hippopotamus sp. nov. Acropodite tip curving cephalically (Fig. 115A , red triangle). Acropodite lacking medial swelling as found in N. hippopotamus sp. nov. (Fig. 100A , red triangle). Prefemoral process curving laterally.
