This genus was traditionally considered to be part of the family Strombidae, the true conchs and their allies. However, recent morphological as well as molecular studies indicate that these ("shinbone shells") should be recognised as a separate family, the Rostellariidae, and this is the way they are treated in the database WoRMS.

The recent species belong to three distinct genera, but several more genera are known from the fossil record.
