General environment
This is a marine species.

Description
Cells flattened dorsoventrally. Motile cells 15-33 µm long, 14-32 µm wide and 7-12 µm thick. Epicone conical or broadly conical. In lateral view, the epicone typically arches dorsoventrally forward giving it the 'droop-nose' look. On the ventral surface, the very long, straight apical groove appears as a central slit within a rather elongated apical crest and extends towards the edge of the cingulum. The groove that extends beyond the wedge-shaped sulcuscingulum junction is mostly hidden beneath a 'flap' of cell membrane on the lower right margin of the right part of the epicone. This flap is pointed towards the apical crest and is in close contact with the sulcal intrusion on the right. Beneath the flap there is a small projection at the bottom of the right epicone. Cingulum deeply excavated, equatorial or slightly premedian, with a descending girdle displacement of 18-27% of the total cell length. Hypocone bilobed and nearly symmetrical. Nucleus spherical and primarily located in the left hypocone, sometimes in the central hypocone or in the epicone. Two to 16 typically elongated, yellowish-brown chloroplasts are scattered in both epi- and hypocone

Type information
Type locality: Hauraki Gulf, New Zealand (Chang & Ryan 2004: 553). Holotype: (Chang & Ryan 2004: 554). Notes: Holotype: Fig. 3. Of four different clonal cultures, selected for maintenance at the National Institute of Water & Atmospheric Research Ltd (NIWA) culture collection, only one (NIWAKC005) was used in the study by Chang & Ryan (2004).
