Description

Cells in straight loose chains, isovalvate; apical axis 9–42 µm. Apertures between adjacent cells square to rectangular. Setae thin, at first parallel to pervalvar axis, then abruptly diverging almost perpendicularly.

Distribution

Ross Sea (Watanabe, 1982); Prydz Bay, East Antarctica (Boden, 1985); South Atlantic, 49°58.75’S 30°10’W (Hendey, 1937).

Comments

Although the distribution of C. laciniosus was reported by Hasle & Syvertsen (1997) as “northern cold water region to temperate?”, there are a few earlier reports from Antarctic waters.
