Notes:
This diatom appears to be closely related to Navicula cryptocephla, but the valve is more rounded with elongate endings. The valve shape and striae pattern resembles that of Navicula hofmanniae, but the specimens encountered in this study were smaller and with denser striae. The diatom also resembles Navicula gregaria, but the striae are less punctate. Thus, this appears to be a new species of Navicula.
