A recent treatise "Contributions to the knowledge of the Triviidae. XXVIII. Revision of the genus Pusula Jousseaume, 1884 with the description of new genera and new species (Mollusca: Gastropoda)" by Fehse and Grego, 2014 suggests that the common "Coffee Bean Trivia" is actually represented by at least two similar yet distinct species. These two specimens are self-collected Gems.
