Diagnosis

Medium-sized (35-70µm) flagellate with a reversed C-shaped body in lateral view. Epicone is low and disk-shaped, cingulum narrow except dorsally where it forms the large phaeosome chamber, occupying the concavity of the "C". Anterior cingular list is small and distally flared as is, according to Balech (1971b), the posterior cingular list. Phaesome chamber formed by lists of the 2 large dorsal hypothecal plates; other authors claim it is formed by cingular lists, (e. g Kofoid and Skogsberg (1928), Taylor (1976)) and has 2 ribs, one on each side of the saggittal suture of the hypothecal plates arising on the tips of the posterior shank of the horseshoe-shaped body. Only a small pore connects the phaesome chamber, in which are the symbionts, with the surrounding water. Sexual reproduction and cyst formation not known. Marine oceanic plankton, in tropical and subtropical regions, rarely reported; seem to be restricted to deeper waters.
