| Abstract |
A new cercozoan flagellate Mataza hastifera n. g., n. sp. is described from a surface seawater sample collected in Tokyo Bay. Cells are 3-5 μm in diameter and have two flagella. The cells alternate between swimming and stationary states in culture. Swimming cells have a nodding motion. Phylogenetic analyses using small subunit rDNA sequences demonstrate that M. hastifera belongs to the clade comprised of only environmental sequences closely related to thecofilosean cercozoans. Ultrastructural observations reveal that M. hastifera is quite similar to members of Cryomonadida, an order in Thecofilosea, and especially to Cryothecomonas spp. The cell of M. hastifera is covered with a thin double-layered theca and possesses a cylinder-shaped extrusome, as reported from cryomonads. On the other hand, the funnel that is characteristic of cryomonads was not found in the flagellar pit of M. hastifera. Combining both morphological and molecular analyses, we conclude that M. hastifera is a new lineage in Thecofilosea and suggest that Thecofilosea may be a larger group than previously thought. |
