Phylogenetic tree of maximum likelihood of the tribe Oryzomyini based on the Cytochrome b gene. The red box highlights the location of Mindomys and Pattonimus (magnified on the right), while the arrow indicates the new species here described as Mindomys kutuku sp. nov. Letters A–D. indicate those clades proposed by Weksler (2006). The values above and below the branches are the bootstrap values and posterior probabilities (BS / PP), respectively.
