Surviving the Messinian Salinity Crisis? Divergence patterns in the genus Dendropoma (Gastropoda: Vermetidae) in the Mediterranean Sea

•Coalescent-based phylogenetic analysis confirmed four well-supported clusters.•Clusters are delimited along a Mediterranean west–east axis.•The estimates obtained indicated two main stages of diversification.•The data suggested that the different lineages predated the MSC.•Within-lineage diversification events occurred in late Pliocene–early Pleistocene.
