No full textThe recent discovery of the genus Moitessieria in subterranean waters of the island of Sardinia provided the opportunity to increase knowledge of the genus in Italy and to revise all the populations known to live in western Liguria (Ligurian and Maritime Alps, Italy). Shell (shape and teleoconch microsculpture) and anatomical characters have been studied in many Italian populations and compared with those of some populations of the following French species: M. simoniana (De Charpentier), M. massoti Bourguignat, M. rayi (Bourguignat), M. juvenisanguis Boeters & Gittenberger, and M. lescherae Boeters. Shell structure was also compared with the following French species: M. vitrea (Draparnaud), M. puteana Coutagne, M. rollandiana Bourguignat, and M. locardi Coutagne. The results suggest that the Ligurian populations belong to M. simoniana, and those from Sardinia are closely related to M. massoti. The latter is herein recognized as a species anatomically and conchologically well distinguished from the "M. simoniana group of forms." The anatomical study (body, genitalia and radula) of the different Moitessieria species herein considered, and of the type species of genus Paladihia (P. pleurotoma Bourguignat), provided results that do not justify the inclusion of both genera in a family, Moitessieriidae, distinct from the Hydrobiidae. Even if Moitessieria and Paladilhia differ in many details, the scheme of their genitalia is basically the same and corresponds to that in the Hydrobiidae. Moitessieriidae is consequently recognized as a junior synonym of Hydrobiidae. The presence in Sardinia of Moitessieria, a genus until now considered proper to southwestern Europe (Spain, southern France, northwestern Italy), is interpreted as additional evidence the Sardo-Corsican complex migrated from the southwestern border of Palaeo-Europe by microplate drift during the middle Tertiary

The taxonomic status of Lartetia cornucopia De Stefani, 1880 (Gastropoda, Prosobranchia)
No full textThe status of Lartetia cornucopia, an enigmatic stygobiont species described by De Stefani (1880), is revised. Shells consistent with the original description and live specimens found in the type locality (the valley of the Arbia River, northeast of Siena, Tuscany) made it possible to perform a detailed study which led to the tentative attribution of the species to the genus Alzoniella Giusti & Bodon, 1984. Giusti's (1975) previous identification of Lartetia cornucopia with a very similar shelled stygobiont species found by him in a nearby site (the Montagnola Senese, approximately 15 km west of the Arbia River) is consequently recognized to be incorrect. The Montagnola stygobiont, corresponding to a species from Prealpine Italy known since then with the name Lartetia virei Locard, 1903, was synonymized by Giusti (1975) with the older Lartetia cornucopia of De Stefani and moved to the genus Paladilhiopsis and thence by some to the genus Bythiospeum. Present evidence shows that this synonymy is incorrect and supports the revival of Locard's name, 'Bythiospeum' virei. © 1995 The Malacological Society of London
A proposed neotype for Hydrobia acuta (Draparnaud, 1805)
No full textA lectotype for Hydrobia acuta (Draparnaud, 1805) ans selected by Boeters (1984) from two syntypes found at the Museum National d'Histoire Naturelle in Paris. Although they are here demonstrated to belong to two different species, the type designation is valid slid, if accepted, H. acuta becomes a junior synonym of H. ventrosa (Montagu, 1803). In order to conserve the current understanding of H. acuta, an application has been submitted to the ICZN to set aside the type designation of Boeters (1984) and to designate a neotype in line with the earlier and more widely accepted usage of the name
