Abstract The recently described taxon Drymoreomys drymorreomys is endemic to the Brazilian Atlantic Forest and its biology and genetics are still poorly known. The pads on the hindfeet are very well developed and there is brown fur on the upper sides of the feet. The Atlantic Forest harbors a high diversity of mammals, 20 percent of which are rodents of the subfamily Sigmodontinae Ribeiro et al.

Automatic assertion inferred from database entries i.

However, the fauna of this biome is still barely known, such that discovery of new species is still common De Vivo et al. It has been found in disturbed and secondary forests as well as in pristine forest, but probably needs contiguous forest to survive.
