Species and subspecies
Species and subspecies within the genus Allogona include:
- Allogona profunda
- Allogona profunda strontiana
- Allogona ptychophora
- Allogona ptychophora solida
- Allogona townsendiana
The classic treatment of this group by Pilsbry[3] divides the genus into two subgenera: Allogona s.s. for A. profunda and its subspecies, and Dysmedoma for the other members of the taxon.
