Reid, D. G., Dyal, P. & Williams, S.T. (2012) A global molecular phylogeny of 147 periwinkle species (Gastropoda, Littorininae). — Zoologica Scripta , 41 , 125–136. Complete species‐level molecular phylogenies have been published for several genera of Littorinidae (e.g. Echinolittorina , Littoraria ). Here we add new sequence data from three genes (28S rRNA, 12S rRNA, cytochrome oxidase c subunit I) for single specimens of an additional 24 species, to make a data set of 147 (97%) of the 152 recognized species of the subfamily Littorininae. This three‐gene data set is analysed to produce a phylogenetic hypothesis for the subfamily, which includes the first complete species‐level phylogeny of the genus Peasiella and the first three‐gene phylogeny of all Littorina species. The non‐planktotrophic species of Littorina have previously been classified together (as subgenus Neritrema ), implying a single origin of this developmental mode. Tests of this hypothesis with the new data are inconclusive, and resolution is not improved in a tree constructed from five genes (adding previously published sequences of 16S rRNA and cytochrome b ). Using available fossils for calibration we generate a BEAST chronogram, which emphasizes that the radiation of Littorina is more recent than that of other littorinine genera. A database is provided, listing all known species of Littorininae, with their distributions, development, ecology and gene sequences, as a tool for future evolutionary studies of this model group.
