The species listed below are excluded from the genus Bensonella and transferred to Boysidia due to the following traits (not shared among all these species): i) apertural dentition more similar to Boysidia (columellar lamella very strong and long, absence of three barriers on the parietal side); ii) surface sculpture similar to Boysidia (radial growth lines, no spiral striae); iii) larger shell sizes (frequently over 4 mm), which is more common in Boysidia representatives.
