H. c. weymeri and H. c. chioneus sequences from Colombia were excluded in the polymorphism analysis, because of the low number individuals available in each case (3 and 1, respectively). * Indicates statistical significance for departure of D_T from neutral expectation at 95%. ^a Number of alleles. ^b Segregating sites. ^c Genetic diversity. ^d Genetic diversity 95% confidence interval. ^e Tajima's parameter.
