FIGURE 3. A. Bayesian tree showing phylogenetic relationships among members of the T. nudigenis complex based on ND2 sequence data. Samples of the CRV population (T. g. suarezi) form a well-supported clade nested within a clade containing South American populations of T. grayi and T. nudigenis. Bayesian posterior probabilities ≥0.95 and bootstrap values>70% are indicated above nodes, respectively. Asterisks indicate maximum values of 1.0 and 100%. Branch colors match those in the haplotype network and tip numbers those in Table 1. B. Median-joining haplotype network confirms either the slight genetic differentiation of the new subspecies, the haplotype sharing between T. g. casius and T. n. nudigenis, and the genetic distinctiveness of T. grayi from Central America, which is paraphyletic with respect to T. g. incomptus. Circles represent different haplotypes, whereas circle size refers to number of individuals per haplotype. Haplotype colors match tips in the phylogeny. Vertical bars and black circles denote substitutions and unsampled haplotypes, respectively.
