Populations sampled and their phylogenetic relationships. The entire distribution of H. melpomene is shown in gray. The entire distribution of the H. cydno/timareta clade is shown with dots (Rosser et al. 2012). Colors depict distributions of races used in this study, with dots indicating the sampling locations, and correspond to the colored dots on the tree. The tree is a compressed version of the whole-genome ML tree (Supplemental Fig. S1). The three general sampling locations, Panama, Peru, and French Guiana, are indicated. The scale bar refers to the number of substitutions per site.
