Contributor: Ian Bishop - March 2016
Length Range: 26-73 µm
Width Range: 8-11.5 µm
Striae in 10 µm: 7.5-9
Valves are lanceolate-clavate and thickly silicified, with rounded apices. Axial area is broad, lanceolate and mottled. A single stigma is present. Striae are thick, shorter near the central area than in the rest of the valve. Areolae are dense and not visible under LM. Raphe is straight and mostly lateral, becoming filiform at both proximal and distal ends. A bisected apical porefield is present at the footpole.

To date, the known biogeographic range of this species is restricted to the southeastern United States (Thomas et al. 2009). Camburn (1978) documented it in Long Branch Creek, South Carolina and a USGS survey of southeastern wadeable streams recorded its presence in Little Haynes Creek, Georgia and Morgan Creek, North Carolina. Other surveys include records from northwest Arkansas.
