). The broadly rounded ends are gently protracted. Length is 78–88 μm, breadth is 21–23 μm. Raphe branches are narrow-lateral with moderately expanded central ends that are slightly deflected to the secondary side of the valve, terminal fissures are widely hooked. The axial area is narrow, linear, and hardly or slightly extended proximally. The central area is regularly expanded transversely rectangular in shape of a semifascia. Striae are moderately radiate in the central third part of the valve, and become gradually subparallel and are finally convergent towards the poles. Due to the domed valve face, the striae appear wavy towards the margins. Striae density is 8–9 and near the ends not higher than
