Rhipidomys emiliae J. A. Allen 1916 Rhipidomys emiliae J. A. Allen 1916, Bull. Am. Mus. Nat. Hist., 35: 525. Type Locality: Brazil, Pará State, Rio Moju. Vernacular Names: Eastern Amazon Rhipidomys. Distribution: E Amazonia, principally in Pará and Mato Grosso east of the Rio Xingu and as far south as Serra do Roncador, C Brazil. Discussion: R. leucodactylus section sensu Tribe (1996). Described as a species of Oecomys, transferred to Rhipidomys by Goodwin (1953), and thereafter associated as a form of R. mastacalis (Cabrera, 1961; Musser and Carleton, 1993) until reinstated as a species by Tribe (1996). Distributional occurrence and morphological discrimination with respect to R. nitela to the west and R. macrurus to the east require amplification. Sympatry reported with R. nitela at Serra do Roncador (Tribe, 1996).
