Euryzygomatomys is a genus of South American rodents, commonly called guiaras, in the family Echimyidae. It contains two extant and one fossil species, found in Argentina, Brazil and Paraguay. They are as follows:

Brandt's guiara (Euryzygomatomys guiara)
Fischer's guiara (Euryzygomatomys spinosus)
†Euryzygomatomys hoffstetteri Goeldi 1901 - Tarija Formation, Bolivia




Etymology


The genus name Euryzygomatomys derives from the three Ancient Greek words εὐρύς (eurús, or eury), meaning "wide, or which extends in width", ζύγωμα or ζύγωματος (zúgōma, zúgōmatos), meaning "a part of the forehead, or the zygomatic bone", and μῦς (mûs), meaning "mouse, rat".




Phylogeny


Euryzygomatomys is the sister genus to Clyomys. Both taxa are closely related to the genus Trinomys.
In turn, these three genera — forming the clade of Euryzygomatomyinae — share phylogenetic affinities with a clade containing Carterodon and members of the family Capromyidae.
Analyses of craniodental characters proposed that Euryzygomatomys — and also Clyomys — may be associated with Carterodon.
However, molecular data suggest the polyphyly of this assemblage of fossorial genera.
