Guiara
Template:Short description Template:Automatic taxobox
Euryzygomatomys is a genus of South American rodents, commonly called guiaras, in the family Echimyidae.[1] 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 1901Script error: No such module "Check for unknown parameters". - Tarija Formation, Bolivia[2]
Etymology
The genus name Euryzygomatomys derives from the three Ancient Greek words Template:Wikt-lang (Template:Grc-transl, or eury), meaning "wide, or which extends in width", Template:Wikt-lang or Template:Wikt-lang (Template:Grc-transl), meaning "a part of the forehead, or the zygomatic bone", and Template:Wikt-lang (Template:Grc-transl), meaning "mouse, rat".[3][4]
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.[5][6] However, molecular data suggest the polyphyly of this assemblage of fossorial genera.[7]
