Haplotype phylogeny for beetle data. The haplotype network presented in  for the haplotypes collected in La Palma. Note that all edges have length 1. The colored dots (black, red and green) represent the sampled haplotypes and the white dots hypothetical intermediates. Dashed boxes correspond to the three phylogroups, 1-3, identified in . The haplotypes found in region R2 are highlighted in red, those found in R6 in green and those found in R3 are indicated by blue circles.
