Ampullataria rotunda – after Decloitre, 1952

Genus Ampullataria Decloitre, 1952

Diagnosis: Test ampulla-shaped, covered with elliptical plates just as in Euglypha species. The plates cover each other partly. The main part of the test is ovoid with a straight tubular neck and a smooth apertural border. These neck has a different structure: the plates are irregularly shaped and do not overlap.
