The Beast tree showing the reconstructed geographic ranges and dated phylogeny of the Poecilimon ornatus group. The values indicated under the branches represent the mean ages of lineage divergence; acronyms on the nodes indicate geographic areas: [A] – Southern, [B] – Central, [C] – North-Western, [D] – Eastern. The different color rectangle on the branches close to the nodes represents different events: pink—vicariance, purple—dispersal. The red dot indicates the split of the P. affinis complex from the P. ornatus group.
