Figure 7 in A new genus and species of rodent from the Brazilian Atlantic Forest (Rodentia: Cricetidae: Sigmodontinae: Oryzomyini), with comments on oryzomyine biogeography
Figure 7. Phylogenetic analysis of oryzomyine relationships: Consensus cladogram of two most parsimonious trees (5513 steps, consistency index = 0.23, retention index = 0.41) of combined molecular (Irbp + cytochrome-b) and morphological characters. Jackknife (> 50%) nodal support indices are shown below branches. Clades A, B, C, and D are the same as those recovered by Weksler (2006). Outgroups include Peromyscus maniculatus (Neotominae); Nyctomys sumichrasti (Tylomyinae); and Delomys sublineatus, Thomasomys baeops, and Wiedomys pyrrhorhinos (Sigmodontinae). Oryzomyine generic taxonomy follows Weksler et al. (2006).
