Taxonomy. Scolomys ucayalensis Pacheco, 1991 View in CoL , right bank of the Rio Ucayali, 2-8 km east ofJenaro Herrera, Loreto, Peru.
Important variation in measurements among known samples of S. ucayalensis suggest it represents a species complex, but additional taxonomic research is needed to clarify this. Monotypic.
Distribution. Extreme S Colombia, E Ecuador, NE Peru, and W Brazil. View Figure
