SPECIES Ctenomys conoveri

Author:Osgood, 1946.
Citation:Fieldiana Zool., 31: 47.
Common Name:Chacoan Tuco-tuco
Type Locality:Paraguay, Boqueron, 16 km W of Filadelfia (22o15S, 60o10W).
Distribution:Gran Chaco of Paraguay, NE Argentina, and SE Boliva.
Status:IUCN Lower Risk (lc).
Comments:Cabrera (1961), based on Osgood (1946), placed this form in a separate subgenus Chacomys, as did Nowak (1999). Recognition of this monotypic subgenus is not supported by allozymes (Cook and Yates, 1994) or sequence analysis (Lessa and Cook, 1998). Karyotype has 2n=48-50 and FN=70 (Anderson et al., 1987).
