Ctenomys fulvus Philippi 1860
Ctenomys fulvus Philippi 1860, Reise Wuste Atacama: 157.
Type Locality: Chile, Antofagasta Prov., Pingo-Pingo.
Vernacular Names: Tawny Tuco-tuco.
Subspecies::
Subspecies Ctenomys fulvus subsp. fulvus Philippi 1860
Subspecies Ctenomys fulvus subsp. robustus Philippi 1896
Distribution: Mountains and Monte desert of NW Argentina and N Chile.
Conservation: IUCN – Lower Risk (lc).
Discussion: Includes robustus, a Rassenkreis subspecies restricted to the oasis of Pica in Tarapaca Prov., Chile (Mann, 1978:292). Cabrera (1961) and Woods (1993) included coludo, famosus, johannis, and tulduco; but Contreras et al. (1977) considered these forms provisionally distinct and Galliari et al. (1996) indicated a lack of data to support change from specific status. Nowak (1999) considered johannis and robustus as distinct species. Karyotype has 2n=26 and FN=48 (Gallardo, 1991), but see Redford and Eisenberg (1992) who reported karyotypes of 2n=26; FN=52 for C. f. fulvus and 2n=25; FN=52 for C. f. robustus. Gallardo (1991) noted that the C-band pattern of robustus differs from that of fulvus but Gallardo and Palma (1992) found little genetic divergence between these two subspecies based upon protein electrophoresis.
