Remarks.

Given our current understanding, we disagree with Richardson (1995: 123), who considered this taxon to be a junior subjective synonym of Bulimus expansus Pfeiffer, 1848. However, the species complex of Drymaeus (Drymaeus) expansus certainly needs further research to establish the relationships. The current systematic position follows Weyrauch 1967b: 485.

Current systematic position.

Bulimulidae , Drymaeus (Drymaeus) protractus (Pfeiffer, 1855).
