Description
Size: Apical axis 2- 24 ┬Ám.

Color: Yellow brown.

Cells are higher than wide in girdle view, with very narrow, slit-like apertures between valves. Chains short. Poles of adjacent valves not touching one another. Three setae of two adjacent valves short, the fourth one straight, elongated, and serving in formation of the more or less spherical secondary colonies by being entwined in the colony center with the elongated setae of other chains. The intercalary setae lie in a plane roughly perpendicular to the chain axis. The terminal setae are widely divergent. Resting spores, both valves rounded and smooth. The central process is similar to that of Chaetoceros curvisetus.

Reproduction is general for group: both sexual and asexual.
