a, Three sympatric species from three locations. (B, Belize; H, Honduras; P, Panama) were targeted for resequencing. The area of sympatry among the three sampled species is highlighted in orange, and the distribution of the whole genus is shown in blue142. The three sampled species are the most common and widely distributed, but they represent just a fraction of the full hamlet diversity. Numbers indicate sample sizes. b, FST estimates among pairs of sympatric species, in order of increasing FST. Colours indicate the species pair, and labels on the x axis the location. c, PCA within each location, including genomic data from a total of 8,247,395 SNPs. PC, principal component.
