Phyllomys is a genus of arboreal spiny rat, geographically restricted to the forests of eastern Brazil.[1]
The etymology of the genus name derives from the two ancient greek words, meaning "plant leaf", and, meaning "mouse, rat".[2] [3]
Phyllomys is the sister genus to Echimys, and then to Makalata. These taxa are closely related to the genera Pattonomys and Toromys.In turn, these five genera share phylogenetic affinities with a clade containing the bamboo rats Dactylomys, Olallamys, Kannabateomys together with Diplomys and Santamartamys.
There are thirteen named species in the genus. These species have frequently been placed in the genus Echimys.[4]
