Figure 2.

Maximum likelihood tree of combined molecular datasets [cytochrome b (Cyt b), interphotoreceptor retinoid binding protein (IRBP)] using Santa Virgínia specimens (UFES2271, UFES2272). Bootstrap nodal support indices and Bayesian posterior probabilities are shown above the branches, respectively. Outgroups include Peromyscus maniculatus (Neotominae); Nyctomys sumichrasti (Tylomyinae), Delomys sublineatus (Sigmodontinae), Thomasomys baeops (Sigmodontinae), and Wiedomys pyrrhorhinos (Sigmodontinae). Available diploid numbers (2n) of clade D are indicated (for details see Table 1), although the lowest diploid number (Nectomys palmipes, 2n= 16, Barros et al. 1992) does not appear in the figure.
