Figure 6 in Characterization of the orchid bee Euglossa viridissima (Apidae: Euglossini) and a novel cryptic sibling species, by morphological, chemical, and genetic characters

Figure 6. Chronogram showing divergence times and phylogenetic relationships of selected lineages in the genus Euglossa and the sibling species Euglossa dilemma sp. nov. and E. viridissima. The tree topology corresponds to that obtained via Bayesian methods. Bayesian posterior probabilities and parsimony bootstrap values are shown for the sister species only. Divergence times were obtained via penalized likelihood using the fossil-calibrated molecular clock procedures described in Ramírez et al. (2010b). The maximum and minimum age estimates for the MRCA of E. dilemma and E. viridissima correspond to the molecular clock analyses in which the MRCA of the genus Euglossa was assigned a fossil calibration of 20 and 15 Myr, respectively.
