Molecular phylogeny and trait evolution of Madeiran land snails: radiation of the Geomitrini (Stylommatophora: Helicoidea: Geomitridae).

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.

Revision of the genus-group R. T. Lowe, 1855 from Porto Santo (Madeira Archipelago), with descriptions of new recent and fossil taxa (Gastropoda, Helicoidea, Geomitridae).

The genus-group R. T. Lowe, 1855 is revised on the basis of conchological, anatomical and genetic characteristics.

Evolutionary diversification of the genus Theba (Gastropoda: Helicidae) in space and time: a land snail conquering islands and continents.

Among oceanic islands, the Canary Islands offer exceptional opportunities for studying speciation processes due to their habitat diversity and well documented geological history. Based on a combined COI+ITS1 data set for more than 140 specimens, we studied the diversification of the land snail genus Theba on the Canary Islands and adjacent African and European continental areas. Phylogenetic analyses resulted in the recognition of 18 genetically distinct clades including at least three new species.
