Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA RODENTIA CRICETIDAE

Scientific Name: Nephelomys albigularis
Species Authority: (Tomes, 1860)
Common Name(s):
English Tomes's Rice Rat
Synonym(s):
Oryzomys albigularis (Tomes, 1860)
Taxonomic Notes: Following Weksler et al. (2006) Oryzomys albigularis has been reassigned to the new genus Nephelomys. The species definition used for the assessment is from Musser and Carleton (2005), but N. albigularis is a complex and is likely to be split into many species, each with a restricted range (Percequillo in prep.).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Reid, F., Samudio, R., Tirira, D., Boada, C., Weksler, M., Anderson, R.P., Rivas, B., Delgado, C. & Gómez-Laverde, M.
Reviewer(s): McKnight, M. (Global Mammal Assessment Team) & Amori, G. (Small Nonvolant Mammal Red List Authority)
Justification:
This species is listed as Least Concern in view of its wide distribution, 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 to qualify for listing in a threatened category.
History:
1996 Lower Risk/least concern (Baillie and Groombridge 1996)

Geographic Range [top]

Range Description: This species occurs from montane forests of easternmost Panamá, north and westernmost Venezuela, the Andes of Colombia and Ecuador, and northern Peru (Musser and Carleton 2005). It has been recorded at 900 to 3,300 m (Percequillo, in prep.; Tirira, in prep.). Emmons and Albuja (1992) reported the species as less as 70 m in altitude, but this may be anomalous.
