Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Percequillo, A., Weksler, M. & Patton, J. L.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
This species is listed as Data Deficient in view of the absence of recent information on its extent of occurrence, threats, status and ecological requirements. Further information is required on the impacts of numerous potential threats to this species, including habitat conversion to soy monoculture and logging.

Geographic Range [top]

Range Description: This species occurs in the east and central Brazil, south of the Rio Amazonas between the lower reaches of the Xingu and Tocantins Rivers (Musser and Carleton, 2005). Also it occurs in four localities from Para and Matto Grosso states, Brazil (Musser et al., 1998).

Habitat and Ecology [top]

Habitat and Ecology: This rodent occurs in the terra firme Atlantic Forest. It has typically captured on ground and under logs in viney forests and thickets and bambu thickets (Musser et al., 1998). Other species of this genus are tied to pristine forest (Patton pers. comm.) so this species might be intolerant of habitat disturbance.
Systems: Terrestrial

Threats [top]

Major Threat(s): The major threat is deforestation due to soy bean plantation and cattle ranching as well as some logging.

Conservation Actions [top]

Conservation Actions: This species occurs in Floresta Nacional de Tapirape-Aquiri. It needs more research to determine habitat limitations (Patton pers. comm.).
