Rhopalophrya Kahl, 1926 (ref. ID; 2013)

Class Kinetofragminophora: Subclass Gymnostomata: Order Haptorida: Family Enchelyidae (ref. ID; 2013)

[ref. ID; 2013]
Body outline shape elongate, flask-like, sometimes slightly asymmetrical, pellicle with widely separated longitudinal ribs and furrows. Some species rounded in cross-section, others somewhat compressed. Oral aperture apical at end of short neck or snout region. Uniform cilia cover the body, those near the oral aperture longer than rest. Usually 1 (rarely 2) spherical macronucleus, centrally located. Contractile vacuole terminal.
