Annotated catalogue of the types of Molluscs taxa described by Marquise Marianna Panciatichi Ximenes d’Aragona Paulucci preserved at the Museum of Natural History of the University of Florence (Part four)

The type specimens of the taxa established by Marianna Panciatichi Ximenes d’Aragona Paulucci are preserved at the Museum of Natural History of the Museum System of the University of Florence. This paper concludes a review of the taxa described by Paulucci and of the 742 type series corresponding to 6771 type specimens. As in the first three contributions already published (Cianfanelli et al. 2021, 2023, 2024), we follow the criterion of treatment in chronological order of publication, as defined in the first part. We therefore examine the last three papers in which Paulucci described new taxa (Paulucci 1882a: 1882b, also republished as 1882c, 1886b). The scheme adopted follows that of the previous three parts with an analytical sheet for each taxon, subdivided into paragraphs (Original publication, Original description, Type locality, Type material, Current status, Remarks) and with the reproduction, for each taxon, of high-resolution photos of a specimen of the type series. Other taxa, cited in the literature and erroneously attributed to Paulucci, or established by Paulucci as nomina nuda or established by Paulucci but invalid, are also listed. This part, being the final one, provides the final summary of the 193 taxa described by Paulucci and published in 11 malacological contributions. Finally, Paulucci’s entire production is analysed, providing a synoptic overview of the taxa she described, reporting their current taxonomic status, highlighting the genera, species and subspecies still considered valid today and those that are junior synonyms.
