Phylogeny

The closest relatives of the genus Thrichomys are two clades consisting of pairs of Myocastorini genera: Callistomys (the painted tree-rat) and Myocastor (the coypu or nutria) in one clade, and Hoplomys (the armored rat) and Proechimys in the other.

The cladogram has been reconstructed from mitochondrial and nuclear DNA characters.[4][5][6][7][8][9][10]
