Sampling sites of Heliconius erato chestertonii and H. e. venus and bayesian tree for the Clade E1 of Heliconius erato. Symbols correspond to population of origin for the individuals of H. e. chestertonii, south (gray) or north (black) and H. e. venus (white). The tree is based on mitochondrial genes of Cytochrome oxidase subunits I and II, leucine-tRNA and has the same topology as the Parsimony analysis. Posterior probability and bootstrap support are indicated on branches of the principal clusters. Individuals of the different subspecies are identified by bars (right).
