Scientific Name: Thylamys pulchellus (Cabrera, 1934)
Taxonomic Notes: This species was previously considered as T. pusillus. A recent study (Teta et al. 2009) demonstrated genetic and morphological differences with T. pusillus (sensu stricto). Morphological differences with T. pusillus were also discussed by Martin (2008).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-05-05
Assessor(s): Flores, D. & Teta, P.
Reviewer(s): Martin, G.M.
This species is confirmed as Least Concern because of its relatively wide distribution, presumed large population (although likely occurrence in few protected areas) and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Habitat and Ecology [top]

Habitat and Ecology:Thylamys pulchellus is endemic to the Dry Chaco eco-region of central and nothern Argentina, with a mixture of grasslands and xerophytic woodlands. Its distributional boundaries are unclear, especially north (where T. pusillus lives), and at the southern and eastern boundaries.

Threats [top]

Major Threat(s): There are no major threats to the species, although some populations are declining due to deforestation, conversion of most areas from native grassland, shrubland and xerophytic chacoan forests to agricultural lands.

Conservation Actions [top]

Conservation Actions: The range of this species overlaps a few protected areas (e.g., Copo National Park in Argentina). More research is necessary to determine its range, extent of possible threats and habitat use.
