|Scientific Name:||Nephelomys devius (Bangs, 1902)|
Oryzomys devius Bangs, 1902
|Taxonomic Notes:||Following Weksler et al. (2006) Oryzomys devius has been reassigned to the new genus Nephelomys.|
|Red List Category & Criteria:||Least Concern ver 3.1|
This species is listed as Least Concern in view of its presumed large population, occurrence in a number of protected areas, and because it does not appear to be under threat and is unlikely to be declining at nearly the rate required
|Previously published Red List assessments:|
|Range Description:||This species occurs in highlands of Costa Rica and westernmost Panamá (Musser and Carleton 2005).|
Native:Costa Rica; Panama

|Population:||It is common in wet highland forest.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||This species primarily occurs in highlands and cloud forest (Musser and Carlton 2005). This species is poorly known, but is thought to consume arbuscular mycorrhizal fungi and may be important spore dispersers (Mangan and Adler 2000). This species is most common in wt highland forest and elfin forest. (Reid 2009). In addition, this species is most abundant along small streams borders by bamboo, with dense growth of ferns and epiphytes (Timm et al. 1989).|
|Generation Length (years):||1-2|
|Major Threat(s):||There are no known major threats to this species. However, deforestation is a threat to some populations.|
|Conservation Actions:||In Costa Rica, it is found in several protected areas, including Amistad and Talamanca.|
