Diversity estimates based on currently recognized species and genetic lineages presented herein.

<p>The number of lineages restricted to each region (distributions based on <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0046578#pone.0046578-Moratelli1" target="_blank">[12]</a>–<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0046578#pone.0046578-Larsen1" target="_blank">[16]</a>) is shown as a percentage of the total. <b>A</b>) percentage of diversity in each region based on currently recognized diversity, <b>B</b>) percentage of diversity in each region based on a species divergence level set at ≥5.0% using cytochrome-<i>b</i> DNA sequence data, <b>C</b>) percentage of diversity in each region based on a species divergence level set at ≥2.0%. Note the proportion of lineages from each region changes from the current levels, when compared to the lineages at 5.0% and 2.0%.
