Ultrastructure and phylogenetic position of Regin rotiferus and Otto terricolus genera et species novae (Bicosoecida, Heterokonta/Stramenopiles)
We describe two novel flagellates isolated from soil, Regin rotiferus and Otto terricolus, genera et species novae, which we cultivated and characterized by light and transmission electron microscopy and by 18S rDNA sequence analysis. Both strains exhibit the key characteristic structural feature of Bicosoecida; i.e. the L-shaped cytostomal root system with an x-fiber, used for feeding. Otto terri
