The subgenus Simplicula Ponte-Lira & M. R. Alonso, 1997 in the genus Canariella P. Hesse, 1918 is elevated to the rank of a genus and seven new fossil taxa of the group are described from Pliocene and Pleistocene to Holocene deposits from the North of Lanzarote, La Graciosa, and the North, West and Northwest of Fuerteventura, Canary Islands.

Available possible type specimens of Macaronesian land snails describd by R. T. Lowe

The more than 20 extant members of the genus Canariella Hesse, 1918 are all endemic to the Canary Islands. From the largest island of the Canarian Archipelago, Tenerife, only 5 species of the genus are currently recognised as valid species. This comparatively low number of species is surprising when compared with the diversity of other endemic gene...

Oceanic islands are renowned for their high proportions of endemic fauna and flora resulting from isolation and associated accelerated speciation and adaptive radiation. Unfortunately, these biotas have also suffered most from direct human-induced extinction, a product of habitat destruction and introduced competitors and predators, or even a fast-...

Late Quaternary deposits containing fossil snail shells were sampled from nine sites on Deserta Grande and three on Bugio, two of the three Desertas Islands in the oceanic Madeiran archipelago. In total, 3,432 shells representing 45 species or subspecies were retrieved. Calibrated amino acid racemization yielded ages ranging from > 45 to 6 ka, with...

A revised and annotated checklist of the living and Quaternary land snails of the Desertas Islands, Madeiran Archipelago, is presented, incorporating recent published work and records previously unpublished. 55 species have been recorded on the Desertas, of which 36 were alive and 41 were found as Quaternary fossils. Only four species are widesprea...

The Geomitrini is the most species-rich group of land snails in the Madeiran Archipelago. The phylogeny of the group is reconstructed based on mitochondrial and nuclear genetic markers. The timing of diversification, the colonisation history of the islands of the Madeiran Archipelago and the evolution of characters of the dart apparatus are studied...

A new species of pill clam, Pisidium interstitialis n. sp. (Bivalvia: Sphaeriidae), is described from wet meadows bordering a small creek in the Odenwald, southwestern Germany, and from a similar habitat in the Thuringian Schistic Mountains, Central Germany. It can be differentiated from the known European Pisidium species on the basis of shell mor...

The clausiliid Ruthenica filograna (ROSSMÄSSLER 1836) is recorded for the first time west of the river Rhine, from the ruins of castle Metternich above the village of Beilstein, district Cochem-Zell, Rhineland-Palatinate, Germany. The habitat is described and the associated mollusk fauna is listed. Information on the ecology, distribution and imper...

Abstract The ground-dwelling species Ferussacia martinae n. sp. is described from Quaternary sand deposits of probably upper Pleistocene age from the Jandía Peninsula of Fuerteventura, Canary Islands. It is compared with the extant Ferussaciidae species from Fuerteventura. The new species clearly differs from Ferussacia submajor (WOLLASTON, 1878) b...

Kurzfassung Die Große Schiefkopfschrecke (Ruspolia nitidula) wurde 2011 erstmals in Rheinland-Pfalz nachgewiesen und bis 2013 zumindest an einem der beiden Fundorte bestätigt. Danach erfolgten keine weiteren Nachweise aus Rhein-land-Pfalz. Die folgende Arbeit berichtet über sechs Neufunde aus dem Bereich des Nördlichen Oberrheintieflands und des Ha...

New sites containing fossil-rich Quaternary deposits have been discovered on Deserta Grande and Bugio, islands in the Madeiran Archipelago, Portugal. Examination of these, together with a reassessment of earlier collections, has led to the identification and description of 6 new species and 2 new subspecies. The revised taxonomy involves species in...

The northern Upper Rhine Plain and the so-called "Electoral Palatinate" in the surroundings of Mann-heim constituted the study area of the excursion of the malacological working group of Baden-Wuerttemberg, from 15 th to 17 th September 2017. Altogether 107 mollusk species representing 75 land snails, 18 freshwater snails and 14 mussels were found....

Desertas islands (Madeira: Portugal), a small sub-archipelago (14,21 km2) of three islets (Ilhéu Chão, Deserta Grande and Bugio) located in the Macaronesian region of Portugal, encompasses a rich land snail fauna, the majority endemic to the Madeira archipelago and exclusive to the islands. Although geologically young (3.2–3.6 Ma), the extant faun...

We proposed the name Wollastonia De Mattia, Neiber & Groh, 2018 for a small group of land snails that are endemic to the island of Porto Santo and some of its sourround- ing islet in the Madeiran Archipelago (De Mattia et al. 2018).Unfortunately, and only explicable as the consequence of a whole chain of small mistakes or omissions, it slipped our...

During the autumn excursion of the malacological working group of Baden-Wuerttemberg joined by 25 participants selected habitats of the region Tauber-Franconia between Wertheim at the river Main and Tauber-bischofsheim were investigated. We focused on semi-dry grasslands, wetlands, and the stream Tauber itself. In total, 110 taxa of the recent faun...

The genus-group Hystricella R. T. Lowe, 1855 is revised on the basis of conchological, anatomical and genetic characteristics. A new genus Wollastonia gen. n., two recent species, W. jessicae sp. n. and W. klaus- grohi sp. n., and one recent subspecies, W. jessicae monticola ssp. n. are described as new to science, as well as five fossil taxa, H. m...

In the context of the “ecological wave”, a phe- nomenon of “Zeitgeist”, triggered by part of the scien- tific community and popularized by the world media, we briefly checked the status of the terrestrial mollusks on Cebu and its satellite Island Bantayan. http://www.conchbooks.de/?t=642&u=31720&bookgroup=&subgroup=

The Red List of land and freshwater molluscs in Germany is published in its 6 th completely revised edition. The new classification is based on criteria proposed by the German Federal Nature Conservation Agency [BfN = Bundesamt für Naturschutz, Bonn] according to the IUCN criteria and gives special regard to short-and long-term trends of population...

Shows species-richness in time and space for three genera from Mid-Atlantic Archipelagoes

Seit 2004 werden in Luxemburg Naturwaldreservate ausgewiesen, die dem Erhalt und der Förderung der Artenvielfalt in Wäldern dienen. In diesen nationalen Schutzgebieten führt die Abteilung für Wald der Naturverwaltung Luxemburg ein umfangreiches Monitoring durch, das sowohl waldwachstumskundliche als auch ökologische Fragestellungen behandelt. Dabei...

Very few species of Trimusculidae are known world- wide: even fewer were recorded from the central Indo-Pacific. In 2004 we obtained a specimen from Bantayan Island, northern Cebu, without further details. A search in readily available literature and the web shows that this specimen does not belong to any described species from the family. The new...

The genus Canariella is endemic to the Canary Islands. Curiously, it was never found on the central island of Gran Canaria but on all other islands to the east (Lanzarote, Fuerteventura) and west (Tenerife, La Gomera, La Palma, El Hierro). This zoogeographic paradox can now be solved. Here we report on the discovery of a Pliocene gastropod fauna on...

Small freshwater mussels are sometimes found attached to the toes of aquatic phase amphibians, but the ecological implications of this interspecific relationship are unknown. Toe condition and mussel presence were recorded for newts caught in 37 ponds in Luxembourg between March and June 2007. All four local newt species were affected (Lissotriton...

Monilearia tubaeformis sp. nov. is described from Fuerteventura ( Canary Islands) and placed in the taxon Lyrula Wollaston, 1878, previously considered as monospecific, for its distinctive type of shell ornamentation. Helix multipunctata Mousson, 1872, from the same island, is also placed in Lyrula because it has similar shell ornamentation. The an...
