Phylogeny and biogeography of the Vitrinidae (Gastropoda: Stylommatophora)

This dataset contains the digitized treatments in Plazi based on the original journal article Hausdorf, Bernhard (2002): Phylogeny and biogeography of the Vitrinidae (Gastropoda: Stylommatophora). Zoological Journal of the Linnean Society 134 (3): 347-358, DOI: 10.1046/j.1096-3642.2002.00010.x, URL: academic.oup.com/zoolinnean/article-lookup/doi/10.1046/j.1096-3642.2002.00010.x The phylogeny of the Vitrinidae is reconstructed in a cladistic analysis based on characters of the genitalia, the copulation behaviour and the radula.

The genera with an atrial stimulator turned out to be the earliest branches of the Vitrinidae, whereas the genera with a glandula amatoria form a monophyletic, taxonomically apomorphic group. The differences between the proposed phylogeny and previous hypotheses are discussed. The ancestral areas of the Vitrinidae and its sister group, the limacoid slugs Boettgerillidae – Limacidae – Agriolimacidae, are estimated using weighted ancestral area analysis.
