Tanglegram of pollinator lineages and host Ficus species. Strict molecular clock (COI) fig wasp and (ETS & ITS) Ficus ultrametric phylogenies were generated using BEAST. Coloured lines connect wasp specimens with the fig species they were collected from (each connecting line is coloured according to fig wasp genus). A relative time scale is given. The nodes used to calibrate the divergence timing estimates are indicated by large open circles. Horizontal open bars represent the 95% upper and lower posterior density intervals around the mean node age. Black vertical bars on the right indicate Ficus subsections. The red vertical line indicates the threshold at which the Yule pure-birth model is inferred to have switched to a neutral coalescent model. Grey boxes indicate clades falling within the coalescent region.
