Abstract:

Two new, recent diatoms, Stephanodiscus suzukii Tuji et Kociolek and Stephanodiscus pseudosuzukii Tuji et Kociolek are described from Lake Biwa, Japan, where they had been identified previously as Stephanodiscus carconensis Grunow var. carconensis and S. carconensis var. pusillus Grunow, respectively. These forms are compared in terms of valve ultrastructure with populations of S. carconensis from North America. The Japanese species differ from the North American specimens in characteristics related to the central fultoportula and rimoportula.
