Haplotype networks from sympatric and allopatric comparisons of selected loci with extreme <i>F</i>_ST values.

<p>(A) The network of the loci <i>ζcop</i> and <i>rpL17A</i> from the sympatric species of the <i>Lutzomyia longipalpis</i> complex shows mixed a haplotype distribution, unlike the two well-separated cluster for the allopatric species. This is in agreement with the low degree of divergence between sympatric and high divergence between allopatric species. (B) The loci <i>per</i>, <i>sec22</i>, <i>up</i> and <i>para</i> presented sympatric and allopatric networks with haplotypes separated by species group, which also corroborates the high values of pairwise <i>F</i>_ST (see <a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0002495#pntd-0002495-t002" target="_blank">Table 2</a>). Each <i>L. longipalpis</i> population is represented by one color: Sobral 1S (orange), Sobral 2S (green), Lapinha (red) and Pancas (light green). Colored circles represent unique haplotypes, and their sizes are proportional to their frequencies. Black circles are hypothetical haplotypes. Curved lines represent alternative branching between haplotypes.
