Valves linear, ca.120 µm long, 22µm broad. Raphe eccentric, fibulae 8 in 10µm, the fibulae in the center more distant, striae punctate 15 in 10µm, crossed by longitudinal fold. Located on : PFBBK1S2 (0.50), loc. 37 x 93. It closely resembles Nitzschia graeffii (Witkowski (2000), Pl. 192:1) but it is shorter and more constricted in the middle. It could be variety of that species, but closer examination is needed to determine its true identity.
