SPECIES Proechimys roberti

Author:Thomas, 1901.
Citation:Ann. Mag. Nat. Hist., ser. 7, 14: 531.
Common Name:Roberto’s Spiny-rat
Type Locality:Brazil, Minas Gerais, Araguari, Rio Jordão.
Distribution:Cerrado of C Brazil and E Amazon.
Status:IUCN – Lower Risk (lc) as P. oris.
Comments:Thomas (1901) considered roberti a close relative of longicaudatus and some subsequent reports have treated it as a subspecies of longicaudatus (Cabrera, 1961; Moojen, 1948; Woods, 1993). Thomas (1904b) suggested affinities with guyannensis and Ellerman (1940) listed as a subspecies of guyannensis. Patton (1987) assigned it to the guyannensis group. Considered a distinct species based on morphometrics (Pessôa et al., 1990) and molecular data (Weksler et al., 2001). Eisenberg and Redford (1999) suggested that oris is probably a synonym for roberti, supported by Weksler et al. (2001). Karyotype has 2n=30 and FN=54-56 (Gardner and Emmons, 1984; Weksler et al., 2001).
