Scientific Name: Thomasomys cinnameus Anthony, 1924
Taxonomic Source(s): Pacheco, V. 2015. Genus Thomasomys Coues, 1884. In: Patton, J.l., Pardiñas, U.F.J. and D’Elía, G. (eds), Mammals of South America Volume 2: Rodents, pp. 617-682. The University of Chicago Press, Chicago and London.
Taxonomic Notes: Thomasomys cinnameus was considered a synonym of T. gracilis by Both Cabrera (1961) and Musser and Carleton (1993), but Voss (2003) Pacheco (2003) and Salazar- Bravo and Yates (2007) recognized T. cinnameus as a valid species. Pacheco (2015) noted that some individuals from Ecuador and Colombia show differences that suggest the presence of more than one taxon; however, more samples are required.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-06-01
Assessor(s): Pacheco, V.
Reviewer(s): Amori, G.
Contributor(s): Barriga, C., Carrasco, J., Loaiza, C., Quintana, H., Lee, T., Tirira, D.G. & Boada, C.
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.

Geographic Range [top]

Range Description:The distribution of this species comprises the Colombian and Ecuadorean Andes, in paramo and montane forests, from Antioquia in Colombia until Azuay in Ecuador. Altitude ranges from about 2,400 to 3,800 m (Pacheco 2015). It also occurs in Carchi province (D. Tirira pers. comm.) and southern Colombia, Nariño Department, Galeras Volcano (M. Gómez-Laverde pers. comm.).

Population [top]

Population:It is rare to uncommon. The Thomasomys cinnameus reported in 1988 was the first report since the original description based on a single specimen collected at 2,438 m near Hacienda San Francisco, Provincia Tunguragua, Ecuador (Voss 2003).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits subalpine rainforest, paramo, minimally disturbed quenoa forests, elfin forest, bogs, and swampy cloud forest. Individuals have been trapped on the ground, among mossy boulders in an old lava flow, in areas with dense canopy and little groundcover but deep moss, and in dense and isolated clumps of composite bushes on exposed slopes covered with tussock grass (Barnett 1999, Voss 2003, Lee et al. 2011). Reproduction evidence was found in August, during the dry season (Barnett 1999). It is terrestrial. Five individuals were taken in Papallacta area in 1978; three were trapped among mossy boulders in an old lava flow that impounds the Rio Tambo to form a lake and two were taken on the ground in Subalpine Rain Forest in the valley of the Rio Papallacta (Voss 2003).
Generation Length (years):1-2

Threats [top]

Major Threat(s): Some populations are threatened by deforestation and habitat fragmentation.

Conservation Actions [top]

Conservation Actions: In Ecuador, this species occurs in two protected areas and close to other two (D. Tirira pers. comm).
