Abstract

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 ± 5.7 μm in depth, 58.2 ± 5.7 μm in width, and 37.3 ± 3.5 μm 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.

Keywords: G ambierdiscus scabrosus; Japan; LM; SEM; ciguatera fish poisoning; epiphytic dinoflagellate; morphology; taxonomy.
