Scientific Name:

Oligoryzomys destructor

Species Authority:

(Tschudi, 1844)

Common Name/s:

English

–

Destructive Pygmy Rice Rat

Synonym/s:

Oryzomys spodiurus (Tschudi, 1844)

Taxonomic Notes:

Musser and Carleton (2005) state that distributional limits, validity of included synonyms, and relationships to other Andean species all require detailed investigation. In Argentina further taxonomical research is needed.

Justification:
This species is listed as Least Concern in view of its wide distribution, presumed large population, it occurs in a number of protected areas, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

History:

2000	–	Data Deficient
1996	–	Lower Risk/least concern (Baillie and Groombridge 1996)
1996	–	Data Deficient
