Oxymycterus nasutus Waterhouse 1837

Oxymycterus nasutus Waterhouse 1837 , Proc. Zool. Soc. Lond., 1837: 16.

Type Locality: Uruguay, Maldonado Dept., Maldonado.

Vernacular Names: Long-nosed Hocicudo.

Distribution: Uruguay and adjacent SE Brazil (Rio Grande do Sul to São Paulo).

Conservation: IUCN – Lower Risk (lc).

Discussion: 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).
