Description
Dorsoventrally flattened cells, 30-40 µm long (x ± s = 34.7 ± 2.8 µm), 32-42 µm wide (35.2 ± 3.9 µm), 17-25 µm thick (21.6 ± 2.3 µm). Epicone acute to truncated, with concave sides but sometimes rounded. Hypocone often truncated and incised by the sulcus, but sometimes semicircular in outline. Cingulum deeply incised, with raised margins, displaced approximately one sixth of the cell length. Sulcus wide, extending deeply into the epicone as a truncated indentation. Apical groove straight, and extending approximately halfway down the dorsal epicone. Nucleus small and spherical, in the centre of the epicone. Chloroplasts 10-20, elongated, radiating in a star shape from a roudn body in the hypocone.
