New systematics of Parmacellidae P. Fischer 1856 (Gastropoda, Pulmonata ), with the recovery of the genus-name Drusia Gray 1855 and the description of Escutiella subgen. nov.

Alberto Martínez-Ortí & Vicent Borredà

Abstract. This paper compares two western Mediterranean species so far included in the genus Parmacella, P. deshayesii from North Africa and P. valenciennii from the south of the Iberian Peninsula. These show many distinctive features that we believe are sufficient to consider them not only as separate species but also to be in different subgenera. Arguments about their conspecificity are clarified and neotypes designated for both. Taxonomic studies of the species of Parmacella has allowed us to propose a revision of the systematics of the family Parmacellidae and to restructure it into two genera: Parmacella and Drusia, the latter an available old genus-name, which in turn is divided into two subgenera Drusia s. str. and Escutiella subgen. nov. We also include a taxonomic key to the family Parmacellidae using the proposed new systematic scenario.

Molecules vs morphology in the taxonomy of the Radomaniola/Grossuana group of Balkan Rissooidea (Mollusca, Caenogastropoda)

Andrzej Falniowski, Magdalena Szarowska, Peter Glöer & Vladimir Pešić

Abstract. The morphology of the shell, penis, and female reproductive organs, as well as the mitochondrial COI and ribosomal 18S (112 and 38 sequences, respectively) were studied in 40 populations of the Balkan hydrobiids Radomaniola and Grossuana. In 19 populations of five nominal species/subspecies, shell morphometry based on seven characters did not confirm the distinctness of the taxa. Despite wide variation, we did not find morphological differences between Radomaniola and Grossuana or between the nominal species assigned to these genera. The COI Bayesian tree proved the monophyly of the group, while the ML tree did not. Both methods revealed three groups: one of Grossuana from Serbia, Bulgaria, Romania and NE Greece (disjunct distribution); and two of Radomaniola from part of the former Yugoslavia and SE Greece. However, only the Radomaniola from the former Yugoslavia was monophyletic. The molecular differentiation was not reflected in morphology, and morphostatic evolution was postulated.

Key words. Grossuana, Orientalina, Radomaniola, COI, 18S

A relict population of Retinella olivetorum in southern France. Biogeographical and historical implications

Frédéric Magnin, Michel Dubar & Laurence Kiss

Abstract. We consider Zonites herculeus Rambur, a Pleistocene fossil land snail of the French Riviera described at the end of the 19th century, a synonym of Retinella olivetorum (Gmelin), a shade loving species until now considered endemic to Italy. We report the recent discovery of both living and Holocene R. olivetorum near Aix-en-Provence (France), about 250 km from the western boundary of its main range. The origin of this disjunct range is discussed. The most consistent hypothesis is the fragmentation of a large Eemian range during the succeeding glacial stage. The persistence of the species through scattered refugia is considered. The resilience of the only French R. olivetorum population to wildfires is also examined.

Anatomy of Neritina zebra from Guyana and Brazil (Mollusca: Gastropoda: Neritidae)

Cristiane Xerez Barroso, Helena Matthews-Cascon & Luiz Ricardo L. Simone

Abstract. Neritina zebra is a common brackish water gastropod living on muddy bottoms with poorly known morphological characters. The morphology, including the variety of colour and pattern of shells, and the anatomy are described. We mainly analyzed the animals collected in the estuary of the Ceará river, Ceará, Brazil, from “Parque Estadual do rio Cocó”, and specimens from other places deposited in institutional collections, from French Guyana (topotypes) to São Paulo. A complete anatomical description is performed, including illustration and discussion main concerned to systematics. Amongst the more important anatomical data are: heart diotocardian; kidneys solid; anterior esophagus with pair of ventral esophageal pouches; odontophore with 4 cartilages and 2 horizontal muscles (m6, m6a); males with penis dorsal-right to snout, bearing a terminal papilla; pallial oviduct triaulic, possessing 3 pallial apertures.

Nomenclatural comments on non-marine molluscs occurring in the British Isles

Dietrich Kadolsky

Abstract. Reviews of the nomenclatural status and related matters on selected non-marine molluscs occurring in the British Islands are provided, and in some cases nomenclatural actions carried out. The most significant points raised are: Paludinella L. Pfeiffer 1841 (Assimineidae) the nominal type species “Helix littorina Delle Chiaie 1828” is recognized as misidentified, and fixed as the species intended by L. Pfeiffer, for which Paludinella globularis (Hanley in Thorpe 1844) is the valid name; Heleobia (Eupaludestrina) Mabille 1877 (Cochliopidae), with type species Hydrobia macei Paladilhe 1867, is a senior subjective synonym of Semisalsa Radoman 1974; Ecrobia ventrosa (Montagu 1803) (Hydrobiidae) is declared nomen protectum, and Turbo eburneus Jacob in Adams & Kanmacher 1798 nomen oblitum; Mercuria anatina (Poiret 1801) (Hydrobiidae) is confirmed as the oldest available name for the Mercuria species aggregate; Physidae, the classification is reviewed and the species acuta Draparnaud 1805 is referred to Physella (Acutiana); this species is here designated as type species of Acutiana Fagot 1883; Ferrissia fragilis (Tryon 1863) (Planorbidae: Ancylinae) is accepted as the senior synonym of F. wautieri (Mirolli 1960); Cochlicopa lubricella (Porro 1838) (Cochlicopidae) is not validly proposed by Rossmässler (1834, 1835); relationship to C. lubricoides (Potiez & Michaud 1838), which may have precedence, remains to be clarified; Papillifera papillaris (O.F. Müller 1774) (Clausiliidae): reports of introductions into the British Isles are summarized; Arion (Arion) vulgaris Moquin-Tandon 1855 (Arionidae) proposed to be maintained as the valid name for the invasive species often referred to as A. lusitanicus [not of Mabille 1868]; to utilize the name vulgaris as intended, a neotype fixation to be validated by the ICZN is recommended; Trochulus sericeus (O.F. Müller 1774) (Hygromiidae) is probably based on juvenile Monachoides incarnatus (Müller 1774); authorship cannot be attributed to Draparnaud (1801); the current species concept requires fixation by a neotype according to article 75.6 ICZN.

Key words. Paludinella globularis, Heleobia (Eupaludestrina), Ecrobia ventrosa, Turbo eburneus, Mercuria anatina, Physella (Acutiana) acuta, Ferrissia fragilis, Cochlicopa lubricella, Papillifera papillaris, Arion vulgaris, Arion lusitanicus, Trochulus sericeus, Cornu, misidentifications, neotype

Contribution to knowledge of the life cycle of Aegopinella epipedostoma (Fagot 1879) (Gastropoda: Pulmonata: Zonitidae) in the laboratory

Elżbieta Kuźik-Kowalska, Beata M. Pokryszko & Małgorzata Proćków

Abstract. Laboratory observations made it possible to ascertain some life cycle parameters of Aegopinella epipedostoma. The eggs are laid in batches of 4–20 (mean 10); they are calcified, white and slightly flattened, of the mean size 1.6 × 1.3 mm; incubation takes 27 to 41 days (mean 35); hatchlings have shells of 1.3–2.0 whorls (mean 1.59). They reach adult size (4 whorls) in 220–298 days. The life cycle pattern is similar to that of Aegopinella nitidula.

A Magellanic mystery. Modiola cuprea Jeffreys 1859 a probable junior synonym of Lissarca miliaris (Philippi 1845) (Bivalvia: Philobryidae)

P. Graham Oliver

Abstract. The taxon Modiola cuprea Jeffreys 1859 is shown not to be the fry of Crenella faba (Müller 1776) and not to belong to the Mytiloidea. Rather it belongs to the Philobryidae and is proposed as a probable junior synonym of Lissarca miliaris (Philippi 1845). Lissarca miliaris and all Lissarca species are confined to the Antarctic and southern oceans in the Magellanic and Austral provinces. The supposed attribution of the type series of M. cuprea as coming from the crop of a bird, shot in Yorkshire, England must be discounted. Ranges, migration routes and flight times of both birds implicated, the Sanderling (Calidris alba) and the Brent Goose (Branta bernicla) do not support such an occurrence. The shell collection of William Bean is extensive and includes much material from around the world and it is proposed that Bean inadvertently gave a local origin to these shells before sending them to Jeffreys. Modiola cuprea can now be removed from the European checklist.
