The project consists of a taxonomic revision and phylogeny of the genus Jeanneretia, an endemic taxon in the Western region of Cuba. Species in this genus live mainly in the mountains, frequenting the limestone areas. Two subgenera with marked differences are described, Jeanneretia s.s. (4 species) without a Gular fold and Guladentia (5 species) with a Gular fold (characteristic of shell). Jeanneretia parraiana is among the most variable species within the genus, composed of five subspecies (J. p. parraiana, J. p. paralella, J. p. arangoi, J. p. carinata, J. p. depressa); some of them show enough variability to be considered valid species.

The literature about taxonomic studies is scarce and only emphasizes the description of the shell based on few specimens (Clench y Aguayo, 1951; Pilsbry, 1894), obviating important elements such as internal and external morphology and natural history. Many taxonomic questions due to the great variety of the shell exist. In addition, elements linked to the taxonomy of the genus such as the radulae, jaws and genitalia are unknown, indicating the need to clarify the taxonomic status of the genus, just like phylogeny and patterns of speciation that are unknown.

The aim of the project is

1. to verify if the genus Jeanneretia really belongs to the family Cepolidae,
2. to examine if there is sufficient anatomic variability for the sub-genera of Jeanneretia to be considered as valid genera, and
3. to examine if there is sufficient anatomic variability for some sub-species of Jeanneretia parraiana to be considered valid species.
