|Scientific Name:||Oligoryzomys microtis|
|Species Authority:||(Allen, 1916)|
|Taxonomic Notes:||Will be transferred to family Cricetidae.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Patton, J.L., Weksler, M., Bonvicino, C.R. & Percequillo, A.|
This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in a number of protected areas, tolerance to some degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.
|Previously published Red List assessments:|

|Population:||This species is extremely common in the appropriate habitat.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||This species occurs in tropical rainforest; it is found on primary, forest edges and secondary growth habitats. Although this species is distributed widely within the Rio Juruá basin (Brazil), it has a very restricted and unique habitat range. It is thought that animals grow rapidly and reach maturity quickly, breeding in successive bouts, in the dry season. Litter sizes based on embryo counts ranged from 2 to 8, with a mode of 4.|
