The nominal taxon Clausilia portensis rested in synonymy during most of the 20th century. On the basis of samples in the Locard collection in Paris, dating from the 19th century, it is considered here to denote the sister species of Macrogastra (Pseudovestia) rolphii. More recently collected material is unknown.
