Notes & discussion: The name magnicordis, means "large heart" in reference to the relatively prominent central body (Romein 1979).

Distinguishing features: Medium-sized species (H ca 7 µm, W ca 9 µm) with flat cylindrical outline, consisting of 20 to 30 wedges with a smooth outer surface and a large and deep distal depression with central body.
