As regards the simple, ancestral pattern of the dorsal dikinetids (both basal bodies of each dikinetid bearing one short cilium), uniform distribution of most cirri on the ventral and dorsolateral sides, and the presence of a short migratory row just behind peristome as well as rod-shaped cortical granules, the Japan form undoubtedly belongs to the genus
