La famiglia fa parte dei Molluschi Prosobranchi, considerati tra i molluschi terrestri più antichi. Sono ascritti a questa Famiglia due Generi: Pomatias e Tudorella con probabili antenati fossili fin dal Miocene, con conchiglia destrorsa, dalla consistenza robusta e con evidenti strie spirali più o meno rilevate e costolatura assiale, sono dotati di opercolo calcareo di forma spirale. In my attempt to contribute to the knowledge of terrestrial molluscs, with no intention of revision, but only with the aim to make it easier to identify them, thanks to an extensive iconography and a few explanatory notes, I examine a Family composed of a number of species limited, but thanks to recent studies, fairly well defined. The Family is part of Prosobranchs Mollusca, considered among the oldest terrestrial molluscs. They are ascribed to this Family two Genera: Pomatias and Tudorella with probable fossil ancestors since the Miocene, with shell clockwise, the texture and robust with obvious spiral striae more or less recognized and axial ribs had a calcareous operculum with spiral form. I molluschi appartenenti a questo gruppo vivono in vari ambienti anche antropizzati. In genere, si rinvengono alla base di rocce e muretti, dove cercano riparo nel substrato, interrandosi ed uscendo in condizioni di forte umidità in ore notturne o subito dopo o durante la pioggia. Hanno una discreta mobilità con andamento particolarmente “barcollante” dovuto al piede diviso longitudinalmente, hanno una lunga e grande proboscide, sono sessualmente distinti ed hanno un leggero dimorfismo sessuale con le femmine leggermente più grandi dei maschi. Le dimensioni della conchiglia sono simili nelle varie specie e si aggirano intorno ai 15- 18mm con variazioni poco significative. Oggi, secondo gli studi destinati all’analisi di genetica molecolare di Pfenninger et al. (2009), sappiamo che nell’area mediterranea esistono in realtà otto specie, geneticamente distinte, del genere Tudorella, tali conclusioni non sono state però recepite da Bank (2011) e da Francisco Welter-Schultes (2012), che mantengono le denominazioni precedenti pur citando il suddetto lavoro, ma affermando che le specie proposte per l’Europa da Pfenninger et al. (2009), richiedono conferma. _________________________________ * Alessandro Margelli [email protected] Via Cerretti 77 - 56020 Santa Maria A Monte (PI) ISSN 2037 – 8996 Vol. XXII n. 7-12/2013 Argonauta ______________________________________________________________________________________________pag. 2______ The molluscs belonging to this group live in different environments also humanized . In general , are found at the base of rocks and walls, where they seek shelter in the substrate, and burrowing out under conditions of high humidity at night or immediately after or during the rain. They have a decent mobility with performance particularly "staggering" due to the foot divided longitudinally , have a long proboscis and large , are sexually distinct and have a slight sexual dimorphism, with females slightly larger than males. The dimensions of the shell are similar in the different species and are around 15-18mm with insignificant variations. Today, according to the studies for analysis of the molecular genetics of Pfenninger et al. (2009), we know that in the Mediterranean there are actually eight species, genetically distinct, such Tudorella, but such findings have not been implemented by Bank (2011) and Francisco Welter- Schultes (2012) , which maintain the previous names while quoting the above job, but stating that the species proposed for Europe by Pfenninger et al. (2009), require confirmation. Ho adottato le denominazioni proposte da Pfenninger et al. (2009) pur non entrando in merito al fatto che le stesse, o parte di loro, abbiano validità specifica o debbano restare a livello di ssp. Pfenninger et al. (2009), affermano che le specie di Tudorella da ritenere valide siano : I adopted the names proposed by Pfenninger et al. (2009) while not getting over the fact that the same, or part of them, have specific validity or must remain at the level of ssp. Pfenninger et al.

    9 Mitt. dtsch. malakozool. Ges. 86 9 – 12 Frankfurt a. M., Dezember 2011 Under Threat: The Stability of Authorships of Taxonomic Names in Malacology RUUD A. BANK Abstract: Nomenclature must be constructed in accordance with agreed rules. The International Commission on Zoological Nomenclature was founded in Leiden in September 1895. It not only produced a Code of nomencla- ture, that was refined over the years, but also provided arbitration and advice service, all with the aim of ensur- ing that every animal has one unique and universally accepted name. Name changes reduce the efficiency of biological nomenclature as a reference system. The Code was established to precisely specify the circumstances under which a name must be changed, and in what way. Name changes are only permitted if it is necessitated by a correction of nomenclatural error, by a change in classification, or by a correction of a past misidentification. Also authorships are regulated by the Code, mainly by Article 50. In a recent paper by WELTER-SCHULTES this Article is interpreted in a way that is different from previous interpretations by the zoological (malacological) community, leading to major changes in authorships. It is here argued that his alternative interpretations (1) are not in line with the spirit of the Code, and (2) will not serve the stability of nomenclature. It is important that interpretation and application of the existing rules be objective, consistent, and clear. Keywords: authorships, malacology, nomenclature, Code, ICZN, Article 50, Pisidium Zusammenfassung: In der Nomenklatur müssen übereinstimmende Regeln gelten. Die Internationale Kommis- sion für Zoologische Nomenklatur (ICZN) wurde im September 1895 in Leiden gegründet.

The following groups of Mesozoic Caenogastropoda are discussed here: Cerithioidea and Littorinoi- dea-Rissooidea seemingly merging with each other during Triassic times; the fresh water and land snails of the Viviparoidea and Cyclophoroidea with unknown marine relatives but a Mesozoic histo• ry; the Vermetoidea, Turritelloidea and Campaniloidea with a late appearance in the Mesozoic; the Ctenoglossa with a continuous history from the Middle Palaeozoic to modern times; the Subulitoidea, Murchisonioidea and Loxonematoidea with Palaeozoic ancestors but unclear Middle Mesozoic rela• tions; the Purpurinoidea as potential ancestors and relatives of the Stromboidea, the latter suddenly appearing in the Jurassic; the Heteropoda and Vanikoroidea with possible relation to each other but very uncertain relations to the others; and the Neomesogastropoda and Neogastropoda which begin their history in the Mid Cretaceous with still rather uncertain precursors.

Many studies focus on the functional drivers which have been regarded as a major force in shell evolution. There is, however, a scarcity in studies that aim at understanding shell form evolution with respect to their ontogeny. Hence, we investigated the evolution of shell form in the micro-landsnail genus Plectostoma (Diplommatinidae) from the viewpoint of shell ontogeny. We examined the aperture ontogeny profiles that describe how aperture form and growth trajectory change along the shell ontogeny, and how the aperture ontogeny profiles relate to the observed shell forms.

ALONSO'" RESUMEN Tudorella ferrugínea es un interesante prosobranquio endémico de las islas Baleares; al no ser conocido su aparato reproductor, fué situado por algunos autores en el mismo subgénero que Pomatias sulcatus,O debido a la similitud existente entre la concha y el opérculo de ambas especies. Describimos aquí por primera vez el dimorfismo sexual, el aparato repro­ ductor de ambos sexos y la rádula de T. ferruginea; a la vista de estos resul­ tados y con los obtenidos en trabajos anteriores, consideramos que el parecido existente entre T. ferruginea y P. sulcatus se debe simplemente a un fenó• meno de convergencia adaptativa. SUMMARY A interesting Prosobranchia endemic of the Baleares is Tudorella ferru­ ginea, which the genital system was unknown. Because of this and due to the similarity between the shells and between the operculums of T. ferruginea and P. sulcatus, both species was placed in the same subgenus by several authors. In the present work, we describe for the first time the sexual dimor­ phism, the genital system of both sexes and the radula of T. ferruginea. Fur­ thermore, with the results obtained in this work and with the data of a anterior publication, we consider that the similarity between T. ferruginea and P. sulca­ tus is due to a convergence adaptative phenomenon. * Departamento de Zoología; Facultad de Ciencias; Universidad de Granada. 70 M.
