Figure 8 from: Fossen EI, Ekrem T, Nilsson AN, Bergsten J (2016) Species delimitation in northern European water scavenger beetles of the genus Hydrobius (Coleoptera, Hydrophilidae). ZooKeys 564: 71-120. https://doi.org/10.3897/zookeys.564.6558

Figure 8 - Species tree with the largest posterior probability from BPP v3.0 analyses conducted on Hydrobius specimens. Multi-locus data (COI, H3 and ITS2) used with Hydrobius convexus included as outgroup. Values above branches indicate range of split posterior probabilities, i.e. the probability for the node representing a speciation event, from four different prior-combinations. Values in red have split probabilities < 1.0. *Clade VII only delimited when specimens from Clade VII were a priori assigned as a potential species separate from Hydrobius arcticus and Hydrobius fuscipes rottenbergii.
