Scientific Name: Akodon pervalens Thomas, 1925
Common Name(s):
English Tarija Akodont, Tarija Grass Mouse
Taxonomic Source(s): Pardiñas, U.F.J., Teta, P., Alvarado-Serrano, D., Geise, L., Jayat, J.P., Ortiz, P.E.,Gonçalves, P.R., and D’Elía, G. 2015. Genus Akodon Meyen, 1833. In: Patton, J.L., Pardiñas, U.F.J. and D’Elía, G. (eds), Mammals of South America, pp. 144-204. The University of Chicago Press., Chicago, London.
Taxonomic Notes: This is a species complex; the relationships of sylvanus, pervalens, tartareus, varius and azarae need further consideration (Anderson, 1997). Subgenus Akodon, formerly Muridae family. Status and relationship variously recognized: named as a subspecies of A. sylvanus by Thomas (1925; as followed by Musser and Carleton, 1993); reallocated to a subspecies of A. varius by Cabrera (1961); retained as a nominal species similar to A. cursor by Myers (1989); placed as a synonym of A. serrensis by Hershkovitz (1990). Taxonomic resolution is needed. There is a paper (in rev) Jayat et al. separating this species from silvanus.

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Dunnum, J., Vargas, J. & Bernal, N.
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 continuing problems with its taxonomy as well as absence of recent information on its extent of occurrence, status and ecological requirements. Until the distribution of this taxa is better understood, it is suspected to be threatened by habitat conversion.

Major Threat(s): The threats to this species are incompletely known, however, the habitats that it has been recorded from are highly-impacted by human activities (e.g. agriculture).

Conservation Actions [top]

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