Time calibrated BEAST phylogeny of Blepharoneura based on 504 bases of mitochondrial COI from exemplars showing at least 0.5% raw mtCOI divergence, combined with the three gene data set of Condon et al. [21]. The topology shown is a majority rule consensus of post-burnin BEAST trees, with median branch lengths from the BEAST analysis, using a coalescent prior on branch lengths and an unpartitioned dataset. Calibration was imposed as normal priors (mean = 3.5 Ma, sd = 1 Ma) applied to stem groups of eight Central American lineages (indicated by diamonds). Posterior probability branch supports are indicated by branch shade and thickness. “Species” designations at right represent clusters of less than 4% raw mtCOI divergence; spp. 1–49 correspond to those in Condon et al. [21]. Clades are labelled A-D to facilitate discussion in the text
