Area of study with sampling localities and haplotype networks (ITS2, CO1) of Nephila populations. The latter are consistent with one species inhabiting the islands of the western Indian Ocean, but in the process of speciating, e.g. on Rodrigues. Islands are colour coded, and the size of each haplotype is proportional to the number of individuals sharing it. Lines connect haplotypes through inferred substitution events (dots).
