Figure 1.

Majority rule consensus of 20,000 post burn-in trees from a 160 million generation Bayesian analysis of COI, COI and 16S mtDNA and 28S nuclear DNA from 64 sciomyzid and one phaeomyiid species under a partitioned substitution model. Bayesian posterior probabilities (x100) appear above the nodes and maximum likelihood bootstrap values (200 bootstrap replicates) appear below the nodes. Nodal support values for individuals of the same species were generally high, but were left off due to spatial constraints (as were those for species of Dictya), but appear in the supplemental figures. Drosophila melanogaster sequences were used to root the analysis. Numbers after species names are specimen numbers (Table 1).
