Phylogenetic relationships within population and species of Heteroderidae. Bayesian 50% majority-rule consensus tree from two runs as inferred from the analysis of the D2–D3 of 28 S rDNA gene sequences under the GTR + I + G model (1nL = 15776.80; AIC = 31899.59; freqA = 0.2234; freqC = 0.2247; freqG = 0.2958; freqT = 0.2561; R(a) = 0.3202; R(b) = 2.082; R(c) = 1.008; R(d) = 0.2953; R(e) = 4.3966; R(f) = 1; Pinva = 0.3467; Shape = 0.7997). Posterior probability values more than 70% are given in appropriate clades. Newly sequenced sample is indicated by red color and bold font.
