Red List Category & Criteria: Data Deficient ver 3.1

This species is listed as Data Deficient in view of the absence of recent information on its status and ecological requirements. This species occurs in a region which is being developed in Perú, however, as almost nothing is known of its natural history it is not possible to predict what impact current land use changes will have on its subpopulations. This species needs further research as it is suspected to be threatened, but to what degree is unknown.

Geographic Range [top]

Range Description:This species is found in less than ten localities in coastal Perú (departments of Ancash and Lima; Solari 2003, Braun et al. 2005, Palma et al. 2014). This species may occur further north, though not much given the available habitat. It is unlikely to be found more extensively to the south. This species has the northernmost range of the genus (Solari 2003). It is found from 300 to 3,000 m asl (Solari 2003, Palma et al. 2014).

Population [top]

Population:There are few specimens from a small number of localities (Palma et al. 2014, S. Solari pers. obs.). At Lachay Natural Reserve (Lima), it was fairly common during a small mammal study (O. Ramirez pers. comm.).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in the coastal deserts and shrublands of Perú (Solari 2003). Unlike other mouse opossums, Thylamys are found in the central and southern part of South America in dry habitats, as opposed to the more mesic environments of other genera (Palma et al. 2002, Giarla and Jansa 2014). The species of this genus are crepuscular, with a diet that is mostly insects and small vertebrates (Palma et al. 2002).

Use and Trade [top]

Use and Trade: This species is not used.

Threats [top]

Major Threat(s): The major threats are agriculture and small settlements (S. Solari pers. comm.).

Conservation Actions [top]

Conservation Actions: This species is found in Lachay National Preserve (Solari 2003). Very little information is available on this species and further research is needed about its ecology and effects of human-induced threats.
