Group Atlanta inflata
From Atlanta inflata (Atlanta inflata) two species were split off by Richter, 1972. These species are rather problematic by the mere fact that too little attention was given to possible differences with other species in the original descriptions. Here the two species of Richter are considered members of one group together with the original Atlanta inflata, though the classification by Richter (1974) does not indicate this grouping.
The group consists of:
Atlanta inflata
Atlanta echinogyra
Atlanta plana
