ジャーナル J Eukaryot Microbiol
Abstract We report a new naked cercozoan flagellate, Esquamula lacrimiformis n. g., n. sp., collected from a sandy beach in Japan. Its cells were 4.5-11.3 μm in length and 3.9-8.8 μm in width and possess two unequal flagella. Cells move in a smooth gliding motion and have a trailing long posterior flagellum. Phylogenetic analyses with small and large subunit ribosomal RNA genes revealed that E. lacrimiformis forms a novel lineage within the Thaumatomonadida, the members of which are flagellates with siliceous scales. However, our light and electron microscopic observations indicated that E. lacrimiformis cells do not possess any siliceous structures. Furthermore, other morphological characteristics, such as the shape of the extrusomes and the structural arrangement of the microbody, were clearly different from those of previously described thaumatomonads. On the basis of a combination of these morphological observations and our phylogenetic analyses, we conclude that E. lacrimiformis should be treated as a new species of a new genus and placed into a new family, Esquamulidae n. fam., under Thaumatomonadida.
