PhylogenyMorphological characters and mitochondrial cytochrome b DNA sequences showed that P. poliopus belongs to the so-called trinitatus group of Proechimys species, and shares closer phylogenetic affinities with the other members of this clade: P. trinitatus, P. mincae, P. guairae, P. magdalenae, P. chrysaeolus, P. urichi, and P. hoplomyoides.[3][4][5][6] {{cladogram|title=Species-level cladogram of the genus Proechimys. |caption=The cladogram has been reconstructed from morphological characters and mitochondrial DNA (cytochrome b) sequences.[3][4][5][6] |align=center |clades={{Cladogram of Proechimys species}} }} References1. ^{{IUCN2008|assessor=Aguilera, M.|assessor2=Ochoa, J.|last-assessor-amp=yes|year=2008|id=18295|title=Proechimys poliopus|downloaded=6 January 2009}} {{Echimyidae nav}}{{Taxonbar|from=Q1770071}}{{Echimyidae-stub}}2. ^{{MSW3 Hystricognathi | id = 13400501 | page = | heading = Species Proechimys poliopus}} 3. ^1 {{Cite journal | last=Patton | first=James L. | author-link=James L.
