Rhagomys Thomas 1917

Rhagomys Thomas 1917 , Ann. Mag. Nat. Hist., ser. 8, 20: 192.

Type Species: Hesperomys rufescens Thomas 1886

Species and subspecies: 2 species:

Species Rhagomys longilingua Luna and Patterson 2003

Species Rhagomys rufescens (Thomas 1886)

Discussion: Generic affinities uncertain: originally allied with Oryzomys-Oecomys ( Thomas, 1917c), or included among oryzomyine genera ( Tate, 1932f), or listed as Sigmodontinae incertae sedis ( McKenna and Bell, 1997; Reig, 1980, 1984; Smith and Patton, 1999). Taxonomic history reviewed and genus critically recharacterized by Luna and Patterson (2003), who considered the biogeographic implications of a new Rhagomys in SE Peru, far away from the Atlantic Forest region where its congenor and other oryzomyine-thomasomyine endemic genera are found.
