Diagnosis: Size about 23–31 µm long and 16–19µm wide. Globular to spherical body. Peduncle short, about 3–6 µm long, and thick, about 4–6 µm wide, with longitudinal sinuation. Pellicle with distinct transverse striations, 36–39 silverlines. Peristomial disc with 20–23µm in diameter and with 9–14 ciliary bands. Macronucleus c-shaped and close to the cell periphery. Round micronucleus, close to the macronucleus. Found on marine polychaetes.

Remarks: diagnoses according to Álvarez-Campos et al. (2014). According to them, this species, when contracted, assumes an oval shape with a deep indentation that contains part of the contracted posterior end, this is because its posterior and anterior folds cover the contracted region.
