Description

Cells solitary, ovoid, 15-22 µm long, 10-11 µm diameter, covered with scales, biflagellate. Flagella emerging from an anterior invagination, dissimilar, one 18-20 µm long, naked, the other 8-10 µm long, thin, covered with scales. Body scales form a corona around the cell (LM); scale base triangular with rounded corners, supporting 3 rods that join in a crown-like arrangement.

Distribution

Sea-ice, Burton Lake, a coastal lagoon in the Vestfold Hills, East Antarctica.

Comments

Thomsen & Ikävalko (1997) listed 13 species of Thaumatomastix, many of which are found in polar waters. However, the cell and scale morphology of our 'type A' appear to differ significantly from those of recognised taxa.
