Abstract
: The Fernando de Noronha Archipelago off NE Brazil harbors a few unique terrestrial gastropod species. One of them, the mono-typic genus Ridleyconcha Christensen, 2020, presents such an idiosyncratic shell morphology that, in the 130 years since its description, it has been variously allocated in unrelated families: Streptaxidae, Endodontidae, Charopidae, Camaenidae, and Scolodontidae. Herein, R. quinque-lirata is included into a molecular phylogenetic framework of stylommatophoran land snails to clarify its taxonomic position. The analysis supports the latest morphological revision classifying Ridleyconcha in Scolodontidae. Considering the present sampling, Ridleyconcha appears to be the sister taxa of Entodina Ancey, 1887.
期刊介绍：
The American Malacological Bulletin serves as an outlet for reporting notable contributions in malacological research. Manuscripts concerning any aspect of original, unpublished research,important short reports, and detailed reviews dealing with molluscs will be considered for publication. Recent issues have included AMS symposia, independent papers, research notes,and book reviews. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous reviewing by independent expertreferees. AMS symposium papers have undergone peer review by symposium organizer, symposium participants, and independent referees.
