SPECIES Oxymycterus paramensis

Author:Thomas, 1902.
Citation:Ann. Mag. Nat. Hist., ser. 7, 9: 139.
Common Name:Yungas Hocicudo
Type Locality:Bolivia, Cochabamba Dept., upper Río Securé, Choquecamate, 4000 m.
Distribution:Middle to upper E Andean slopes, ca. 1000-4000 m, in SE Perú, WC Bolivia, and NW Argentina.
Status:IUCN – Lower Risk (lc).
Comments:Parenthetically mentioned as a subspecies of rutilans (= O. rufus) by Hershkovitz (1966c) but most systematists have recognized paramensis as a species (Anderson, 1997; Cabrera, 1961; Gyldenstolpe, 1932; Honacki et al., 1982; Musser and Carleton, 1993). Allozymic (Hinososa et al., 1987) and gene-sequence (Hoffmann et al., 2002) analyses support sibling kinship with O. hiska, and the latter study underscores its genetic differentiation from O. rufus. Musser and Carleton (1993) suggested that placement of jacentior with this species merits reconsideration; Cabrera (1961) retained it, nigrifrons, and the nominate form as discernable subspecies, as did Anderson (1997:Fig. 728) for Bolivian populations.
