Outline shape of body viewed from dorsal surface is like that of a tulip. Slightly compressed dorso-ventrally with well-developed edges of body forming wing-like extensions which turn towards each other over the ventral surface. This means that the body is approximately C-shaped in cross-section. Somatic cilia mainly restricted to ventral surface but some of the right hand kineties do cross onto the dorsal surface at the anterior end. These then curve completely around C-shaped apical edge and back down the left ventral surface. There appears to be a central area between left and right kineties that is devoid of cilia. The macronucleus is ovoid. The oral aperture is oval and supported by a basket of trichites. There are 2 contractile vacuoles, one on the right anterior edge and one on the left posterior edge.
