Description of Psalteriomonas

Vahlkampfiid, the flagellated stage of which has four nuclei and four sets of four flagella, giving rise to mononucleated amoeboid stage. From anoxic habitats. With methanogenic bacteria. Type species, P. lanterna (Broers et al., 1990). This genus is probably most closely related to Tetramitus because of similarly complex microtubular and fibrous roots derived from the flagellar basal bodies.
