The species of spiny rats in the genus Trinomys are apparently all Brazilian.[3] In particular many of them are endemic to the Atlantic Forest of southeastern Brazil. Not much is known for certain about their ranges however, which still are being investigated, with frequent extensions to the recorded distributions of several species in various ecological classes of forest and dry land. They do not however appear to occur at high altitudes, and several of their ranges appear to be parapatric.[4]
Phylogeny
Genus level
Trinomys is the sister genus to the fossorial genera Clyomys and Euryzygomatomys. In turn, these three genera — forming the clade of Euryzygomatomyinae — share phylogenetic affinities with a clade containing Carterodon and members of the family Capromyidae.
