Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| B. S. Kues et al. 2002 | The keel on the outer margin of the dorsal surface is strongly rugose to subnodose, and the basal bourrelet is slightly swollen and also rugose, both characteristic features of the common Late Pennsylvanian species A. subrugosa. Because some areas of the shell, including the earlier whorls, could not be observed, assignment to this species is tentative. |
