The cells of this species have a distinctive body, typically falling within a size range of 21 to 56 μm in length and 11 to 29 μm in width. The isthmus, a narrow portion that connects the semicells, has a width ranging from 4 to 11 μm. This results in a characteristic length-to-width ratio (L/W) of approximately 2, indicating a moderately elongated shape. The semicells themselves exhibit a spherical morphology, adding to the unique appearance of this species. Notably, the cell wall is smooth, further contributing to its distinct features.
