Fig. 3 in First Phylogenomic Assessment of the Amphitropical New World Ant Genus <i>Dorymyrmex</i> (Hymenoptera: Formicidae), a Longstanding Taxonomic Puzzle

Fig. 3. Divergence dates of Dorymyrmex and outgroups as estimated in MCMCTree (in PAML v4.9), with a map of specimen collection localities. Estimated node ages are displayed with 95% highest probability density (HPD) distributions.Two soft calibration points were used, indicated with grey HPD distributions: (i) The root node 'L(DF)', uniting Leptomyrmex + (Dorymyrmex + Forelius), was assigned a range of 59–42 Ma, and (ii) the divergence between D. planidens and D. bicolor (Node 1) was assigned a range of 33–13 Ma, both based on previous studies incorporating other dolichoderine genera and fossil calibrations (Ward et al. 2010; Boudinot et al. 2016). For full collection details, please see SuppTable 2 (online only); for all HPD distributions, Supp Fig. S4 (online only); for all node age estimations, Supp Fig. S5 (online only). Figure was created using the R packages MCMCTreeR and phytools (phylo.to.map function).
