Scientific Name: Brucepattersonius iheringi
Species Authority: (Thomas, 1896)
Common Name(s):
English Ihering's Hocicudo, Ihering’s Brucie, Ihering’s Akodont
Oxymycterus iheringi Thomas, 1896
Taxonomic Notes: This species has been assigned various generic associations; ncluded in Microxus or Akodon (Cabrera 1961, Ellerman 1941, Gyldenstolpe 1932, Moojen 1952); reallocated to Oxymycterus by Massoia (1963) and thereafter classified (Musser and Carleton 1993); recently assigned to the new genus Brucepattersonius by Hershkovitz (1998) - the Argentinian populations are doubted to belong to this species Hershkovitz (1998). An allocation supported by Bonvicino et al. (1998) and Mares and Braun (2000).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Christoff, A., Leite, Y. & Patterson, B.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is listed as Least Concern in view of its wide distribution and presumed large population. It is known from several locations and occurs in several protected areas and is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.
Previously published Red List assessments:
1996 Lower Risk/least concern (LR/lc)
