Valves of Diploneis marginestriata are narrow, linear elliptic, and broadly rounded. The central area is small, not inflated and elliptic. The raphe is narrow. The longitudinal canals are straight and nearly parallel throughout the length of the valve. Striae are radiate, except in larger specimens the striae are nearly parallel in the center, becoming convergent toward the apices. Areolae are not discernable in LM.
