Scientific Name: Akodon aliquantulus
Species Authority: Díaz, Barquez, Braun & Mares, 1999
Common Name(s):
English Diminutive Akodont, Diminutive Grass Mouse
Taxonomic Source(s): Jayat, J.P., Ortiz, P.E., Pardiñas, U.F.J. and D'Elía, G. 2010. The Akodon boliviensis species group (Rodentia:Cricetidae:Sigmodontidae) in Argentina: species limits and distribution, with the description of a new entity. Zootaxa 2409: 1-61.
Taxonomic Notes: A. boliviensis species group (Myers et al. 1990). Further taxonomic research is needed because the validity of the taxon is currently in debate.

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Pardinas, U. & Jayat, J.P
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is listed as Data Deficient in view of the absence of recent information on its status and ecological requirements. Its very restricted range and the possibility that current threats from fire and cattle ranching are threatening the species, however, there is not sufficient information to quantify these threats and further research is necessary in order to assess the species.

Geographic Range [top]

Range Description:This species is known only from type locality: Argentina, Tucumán Province, Tafí Viejo Department, Las Aguitas, Cumbres del Tafícillo, 1700 m asl; 26°42′S, 65°22′W (Musser and Carleton 2005).

Population [top]

Population:There is no information available on the population and/or abundance of this species, there only two specimens collected from this species.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Inhabit high montane grasslands and although diet is unknown, they are thought to specialize in soil invertebrates like other Akodons (Diaz et al. 1999).

Threats [top]

Major Threat(s): Rare, with restricted distribution; considered a locally threatened species for Tucuman Province, Argentina (Tabeni et al. 2004). There is threat by intentional fire for cattle and agricultural activities (Jayat, J.P pers. comm.)

Conservation Actions [top]

Conservation Actions: The range is included in a provincial protected area (Ecological Park Sierra de San Javier).
