Tetramitus thermacidophilus n. sp. is a novel thermophilic and acidophilic amoeboflagellate isolated from acidic hot springs in the Caldera Uzon (Kamchatka, Russia) and in Pisciarelli Solfatara (Naples, Italy). We describe it based on physiological, morphological, and sequence data. It was grown in monoxenic culture on the archaeon Acidianus brierleyi as food. Tetramitus thermacidophilus multiplies in a pH range from 1.2 to 5 and in a temperature range from 28 degrees C to 54 degrees C. The shortest doubling time was 4.5 h at pH 3 at 45 degrees C. Its spindle-shaped biflagellated stage was only rarely found in culture. The amoeboid stage shows the typical locomotive form of vahlkampfiid amoebae. Sequence comparisons of the internal transcribed spacer sequences and the small subunit rRNA genes confirm that T. thermacidophilus is a novel species within the genus Tetramitus and that both isolates belong to that species.
