Nannaria "Sagittata" incertae sedis Fig. 125

Material examined.

United States - West Virginia • 1 ♂; Raleigh County, Grandview State Park NE of Beckley; 37.8302°N, - 81.0635°W; 22 Sep. 1962; R. Hoffman leg.; VMNH NAN0316. For detailed collection data see Suppl. material 7 .

Hypothesized placement.

Nannaria “Sagittata” specimens are hypothesized to be closely related to Nannaria tasskelsoae sp. nov. based on close geographic proximity and the following combination of gonopodal characters. Acropodite gently curving medially before bending posteriorly at tip. Prefemoral process arising from pronounced prefemoral spine. Nannaria “Sagittata” specimens differ from N. tasskelsoae sp. nov. based on the following gonopodal characters: Acropodite tip serpentine and pointed, not rectangular and blunt as in N. tasskelsoae sp. nov. Prefemoral process serpentine and directed ventrally at tip, crossing acropodite in medial view (Fig. 125B , red arrow), not simple, curving medially as in N. tasskelsoae sp. nov. Prefemoral process arising medially from prefemoral spine, not dorsally as in N. tasskelsoae sp. nov. (Fig. 125A , red triangle).
