The triviid genus Pusula Jousseaume, 1884 is distinguished from the other genera within the Triviidae and all 19 known recent and fossil taxa are revised and discussed. All recent available information as well as the original descriptions and the types were studied in detail. The study resulted in the description of two new genera – Pseudopusula gen. nov. and Quasipusula gen. nov. – based on radula morphology. Four new taxa in the genus Pusula are introduced as well as two new species in the new genus Pseudopsusla. All species are briefly discussed and compared with related forms, and the available zoogeographical data is summarized into distribution maps. The identities of Cypraea cimex Owen in G. B. Sowerby II, 1870 and Cypraea pullata Owen in G. B. Sowerby II, 1870 are clarified. All types of the fossil species from the Florida Plio-Pleistocene established by Petuch (1987; 1991; 1994) and Petuch & Drolshagen (2011) are shown for the first time by adequate photographs. Many of them were determined to be junior synonyms of previously described taxa.
