A time calibrated mt COI BEAST phylogeny of Partulidae. Red dots represent calibration points based on Society Island ages. A: Bora Bora, 3.27 Mya [81], on the node supporting the Eastern Partula clade; B: Raiatea, 2.71 Mya [82], on the node supporting the Raiatean Partula clade; C: Tahiti, 1.44 Mya [82], on the node supporting the oldest exclusively Tahitian Partula clade. Also given on their respective nodes are the estimated divergence times of the non-Palauan Western Partula clade (2.41 Mya), the genus Samoana (2.12 Mya), the Eastern Samoana clade (Marquesas, Society and Austral archipelagoes; 1.12 Mya), Palauan Partula (1.8 Mya) and the genus Eua (2.31 Mya). 95% Highest Posterior Density (HPD) age intervals of major clades are shown as red bars. See Additional file 2: Figure S2 for a full-scale version of this topology containing taxonomic details and date estimates for each node.
