From: New freshwater mussel taxa discoveries clarify biogeographic division of Southeast Asia
Time-calibrated multi-locus phylogeny of the Unionidae based on the complete data set of mitochondrial and nuclear sequences (five partitions: three codons of COI + 16 S rRNA + 28 S rRNA). Red numbers near nodes are BPP of BEAST v2.6.1. Black numbers near nodes are the node ages. Node bars are 95% HPD of the divergence time. Age reconstructions for weakly supported nodes (BPP < 0.75) are omitted. Pie charts at nodes indicate the probabilities of certain ancestral areas for clades of interest with respect to combined results under two different statistical modeling approaches (S-DIVA and Bayesian MCMC analysis). New generic and species names are colored red. Outgroup and non-target clades are collapsed. Stratigraphic chart according to the International Commission on Stratigraphy, 2019.
