Lectotype designation for Putzeysia clathrata (Aradas, 1847) (Gastropoda Eucyclidae) and its systematic position

Abstract

In the present work we discuss the validity of Putzeysia clathrata (Aradas, 1847) (Gastropoda Eucyclidae) currently considered synonym of P. wiseri (Calcara, 1842), despite being the type species of the genus Putzeysia Sulliotti, 1889. Reported as a fossil for the Early Pleistocene of Sicily and Calabria, it is here redescribed for the first time and, at the same time, its taxonomic position is discussed. planulatis, et subcanaliculatis, lineis longitudinalibus transversisque, elevatis, aequidis-tantibus grosse clathratis, et in angulis sectionum subtuberculatis; apertura suborbiculari, labro subincrassato ”. conservation, was also examined uncoated under a LMU Tescan Vega Scanning Electron Microscope in Low Vacuum modality, to investigate its micro-morphology.
