Systematics

The genus contains the following species:

Phylogeny

Diplomys is a member of the Echimyini clade of arboreal Echimyidae rodents. The closest relative of Diplomys is Santamartamys, reflecting the fact that these taxa have once been classified in the same genus. These two genera constitute the sister group of the "Dactylomyines", a clade of South American bamboo rats. All these taxa are closely related to the genera Echimys, Phyllomys, Makalata, Pattonomys, and Toromys. In turn, these genera share phylogenetic affinities with the clade containing Lonchothrix and Mesomys, and with Isothrix.
