Nucleotide sequencing was conducted using BigDye Terminator v3.

The coronoid processthe frontmost of the three main processes projections at the back of the jawbone, is large and about as high as the condyloid process behind it. Drymoreomys albimaculatus Percequillo, Weksler, and Costa, Select a section on the left to see content.

Outgroups include Peromyscus maniculatus Neotominae ; Nyctomys sumichrasti TylomyinaeDelomys sublineatus SigmodontinaeThomasomys baeops Sigmodontinaeand Wiedomys pyrrhorhinos Sigmodontinae. Branch support was estimated by Bayesian posterior probabilities BPP. FISH detected telomeric signals at the ends of all chromosomes and additional telomeric sequences were found in the pericentromeric region of both X and Y chromosomes Fig.

Two simultaneous analyses were performed to ensure convergence on topologies. Distribution extension of Phaenomys ferrugineus Thomas,and new data on Abrawayaomys ruschii Cunha and Cruz, and Rhagomys rufescens Thomas,three rare species of rodents Rodentia: Your basket is currently albmaculatus.

The crests on the braincase and interorbital region are weakly developed.

Karyologic diversification and phylogenetic relationships of the genus Thalpomys Rodentia, Sigmodontinae. Metaphases were obtained in vivo from spleen and bone marrow, according to Ford and Hamerton with modifications.

Our analyses also recovered Drymoreomys albimaculatus as the sister species of Eremoryzomys polius and both species diverged early in the clade D Fig.

According to those analyses, Percequillo et al.

In this sense, tandem fusions have perhaps played significant role in clade D, resulting in the lower diploid numbers. Drymoreomys is a rodent genus in the tribe Oryzomyini that lives in the Atlantic Forest of Brazil.

Thus, some external morphological traits were similar to those described for Rhipidomys and Oecomys as reported Percequillo et al. The bony palate is broad albjmaculatus short, with the posterior margin between the third molars Drymoreomus. For instance, a superficial morphological comparison among sex chromosomes from Table 1 could suggest the occurrence of pericentric inversions, or whole-arm heterochromatin additions or deletions. It is one of several tribes recognized within the subfamily Sigmodontinaewhich encompasses hundreds of species found across South America and into southern North America.
