Diagnosis: These specimens were present in a sample from Lake Argentina, near El Calafate, Argentina. They lived for at least four weeks in a wet mount kept in a moisture chamber. The cell body is more or less globular and about 7 µm in diameter. The tectum is covered with a large number of small oval plate scales which are less distinct as those of the Dutch and German specimens. The body itself is covered with a number of ovoid shaped elements, c. 2-2.3 µm long and 1.7-1.9 broad. Nucleus is 4 µm and nucleolus 1.9 µm.
Ecology: The sample came from a small natural pond in a nature reserve along the coast of Lake Argentina near the village of El Calafate in Argentina.
