. Body broadly to narrowly reniform with a somewhat rhomboid appearance when viewed ventro- or dorsolaterally. Macronucleus between anterior and posterior end of adoral zone, globular to oblong; one globular to broadly ellipsoid micronucleus. Contractile vacuole terminal. Epicortical scales about 1.25 × 0.45 µm in SEM, flat with margin curled up. On average 11 ciliary rows; caudal cilium about 20 µm long. Perizonal stripe composed of five kineties extending approximately 46% of body length and forming about 19 false kineties. Adoral zone extends about 50% of body length, composed of an average of 11 polykinetids.

After formation of the prospective adoral polykinetids, an intense proliferation of basal bodies begins in all somatic ciliary rows. First, the basal bodies of the individual dikinetids go apart more or less distinctly. Then a new basal body develops in front of the anterior basal body generating a triad. Subsequently, a fourth basal body forms ahead of the posterior basal body producing a tetrad. Eventually, the tetrad splits into two pairs of dikinetids. The replication of dikinetids finishes in mid-dividers, i.e., when all somatic ciliary rows are arranged meridionally and composed of comparatively narrowly spaced dikinetids (
