The numerically dominant diatom of a Pleistocene marine littoral assemblage has been ascribed to the Naviculae microstigmaticae section and assigned a "new species" status. Scanning electron and light photo micrographs have been presented to demonstrate the structural features used in the morphological delineation of the taxon Navicula subfossilis sp.nov. The phenotypic characteristics of allied forms have been evaluated and their structural relationships have been assessed.
