Description
: Cell outline is oval-ovoid. Cells are about 8 µm long, anteriorly narrow and posteriorly broad with a short anterior neck. Two flagella insert below the neck are acronematic and are slightly longer than the cell. The nucleus is centrally located. The cells swim backward with the flagella, which point behind the swimming cells. Food materials are shown in the posterior end of the cell. Not common. Only found once at Woolooware Bay.

). It has not been reported from freshwater sites. Previously cell lengths were reported to be from 4 to 18 µm. This species is distinguished from
Telonema antarctica
Thomsen, 1992
by the cell shape.
Telonema antarctica
is reniforme.
