Figure 1. Sampling localities of Calotes versicolor on Hainan Island and the mainland.

Samples are numbered following Table 1. Yellow and blue circles represent lineage A haplotypes and lineage B haplotypes, respectively. The sampled C. versicolor-like population of Yunnan is indicated by the black triangle. Populations with mixed haplotypes are represented by pie charts indicating the proportion of each haplotype. The approximate position of the non-physical barrier is shown.
