Gocevia pontica Valkanov, 1934
Diagnosis: Clearly addressed bipolarity. Body covered by a weakly flexible tectum covered with foreign bodies. The tectum does not fit closely to the cell body and does not follow all of its changes. In shaken, shriveled specimens, the tectum assumes a spherical shape. Pseudopodia short, finger-shaped, form on the entire lower surface of the body. The cell has the ability to spread out on the substrate, taking the form of an irregularly constructed disk. With this disc-shaped spread, however, the contact surface of the animal is only partially in contact with the substrate (cover slip). Division of the plasma into ecto- and endoplasm indistinct. Sometimes shell-less individuals can be observed. Empty shells are very common in specimens. Rarely are two individuals found enclosed in a common envelope, a phenomenon not found elsewhere in the genus Cochliopodium. Many animals have two or more nuclei instead of one.
Remarks: Valkanov: “As said, the form Gocevia pontica is very close to the Cochliopodium species obscurum. The genus Gocevia differs from the genus Cochliopodium in the following characteristics: Cover thick, does not follow all changes of the body. Plasma not clearly separated into ectoplasm and ectoplasm. Absent any typical bilateral or radial symmetry exhibited by certain species of Cochliopodium. Occurrence of wired and unwired individuals.”
