Ileonema Stokes, 1884 (ref. ID; 2013)

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

Synonym Monomastix Roux (ref. ID; 1618)

[ref. ID; 2013]
Body outline shape elongate and flask-like, flattened laterally. Broadly rounded posteriorly, narrowing towards anterior. Rather contractile. Apical region bears a long retractile flagellum-like organelle which in one species is borne upon a thicker, twisted retractile rod. Body ciliation uniform and complete. Cytopharynx armed with delicate trichites. Macronucleus rounded in one or two parts. Single contractile vacuole terminal.
