SPECIES Oxymycterus nasutus

Author:Waterhouse, 1837.
Citation:Proc. Zool. Soc. Lond., 1837: 16.
Common Name:Long-nosed Hocicudo
Type Locality:Uruguay, Maldonado Dept., Maldonado.
Distribution:Uruguay and adjacent SE Brazil (Rio Grande do Sul to São Paulo).
Status:IUCN – Lower Risk (lc).
Comments:Comparisons with O. iheringi provided by Massoia and Fornes (1969). They (and Vitullo et al., 1986) further noted the morphological distinction of O. nasutus from O. rufus, under which it had been ranked as a subspecies (Cabrera, 1961); pronounced divergence from the latter sustained by genetic (cytochrome b) and morphometric analyses (Hoffmann et al., 2002).
