Three extant species of the genus Paralia (Bacillariophyceae) occur along the coast of Japan, two of them are new species. Observations of living populations suggested that significant characters for separating Paralia species are (1) structure of the mantle of the separation valve; (2) shape of the linking spines; (3) topography and morphology of valve face on the separation valve, and possibly (4) cingulum structures; and (5) rimoportula morphology. Some features vary but the structure of the separation valves in girdle view was stable in all specimens. Based on these criteria, we identified Paralia sulcata (Ehrenberg) Cleve and two new species, P. fenestrata Sawai & Nagumo sp. nov., and P. capitata Sawai & Nagumo sp. nov. from coast of Japan.
