Abstract
Qualitative, mensural, genetic, and phylogenetic analyses were conducted to clarify species limits,
distributions, and relationships in the poorly known Amazonian rodent genus Scolomys. Scolomys me-
lanops is characterized by consistent differences in comparison with all other samples of the genus.
However, our data do not support the recognition of S. juruaense as a valid species, but rather as a sy-
nonym of S. ucayalensis. Only minimal differences in Cyt-b sequences were present between S. ju-
ruaense and S. ucayalensis, and phylogenetic analyses consistently retrieved a monophyletic genus
Scolomys with the relationship ((S. juruaense + S. ucayalensis) + S. melanops). The apparent morpho-
