A new epiphytic dinoflagellate is described, G ambierdiscus scabrosus sp. nov., from tidal pools and rocky shores along the coastal areas of Japan. Cells are 63.2 +/- 5.7m in depth, 58.2 +/- 5.7m in width, and 37.3 +/- 3.5m in length. The plate formula of G .scabrosus is Po, 4, 0a, 6, 6c, ?s, 5, 0p, and 2. Morphologically, G .scabrosus resembles G .belizeanus as follows: anterioposteriorly compressed cell shape, narrow 2 plate, and areolated surface. Despite this similarity, the cells of G .scabrosus can be distinguishable by the presence of the asymmetric shaped 3 plate and the rectangular shaped 2 plate.
