This taxon used to be called Synedra pulchella. The frustules narrow toward the ends in girdle view. It has a linear valve tht is lanceolate and has slightly attenuated apices that are rostrate. The psuedoraphe is distinct and sometimes widens toward the central area, which is slightly swollen. The striae are punctate and parallel (Patrick and Reimer 1966).
