Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA RODENTIA CRICETIDAE

Scientific Name: Tapecomys primus
Species Authority: Anderson & Yates, 2000

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Dunnum, J., Bernal, N. & Patterson, B
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
Although this species is known mainly from two isolated locations (four records) from a large area, it is listed as Least Concern as it is likely to range more widely as there is a lot of available habitat for the species, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. More information is needed to confirm the conservation status and range of this poorly known species.

Geographic Range [top]

Range Description: This species is known only from the type locality: southeast Bolivia, Tarija Department, Tapecua (21°26'S, 63°55'W), at 1,500 m (Anderson and Yates, 2000), and from 24°04'S at approximately 63°55'W at 1,200 m in Jujuy Province, Argentina (Ferro et al., 2005).

Population [top]

Population: It is known only from four specimens (2 in Bolivia and 2 in Argentina). Attempts to collect additional specimens in May 1993 at the type locality were unsuccessful. It is not known whether this is indicative of a general rarity of this species, a low population level at that time, or a poor understanding of the habitat and habits of this species (Anderson and Yates, 2000).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: The habitat around Tapecua is a mixture of cloud forest vegetation, patches of columnar cacti and leguminous trees in open areas and broadleaf canopy trees and thick brush on hillsides and in ravines. This type of habitat extends for many kilometers to the south and north, and Tapecomys is likely to occur throughout. It is possible that this species is partially arboreal (Anderson and Yates, 2000). In Argentina it was collected in similar habitat to the type locality. It is not known if it occurs in modified habitats.
Systems: Terrestrial

Threats [top]

Major Threat(s): The threats to this poorly known species are not known.

Conservation Actions [top]

Conservation Actions: It has not been recorded from any protected areas. Further research is needed into the range, habitat, ecology and threats to this species.
