Taxonomy. Ctenomys dorbigny J. R. Contreras & A. N. C. Contreras, 1984 View in CoL ,
“Paraje | Mbarigtii, Departamento Beron de Astrada, Provincia de Corrientes, a 27°33’ de latitud Sur y a 57°31" de longitud oeste,” Argentina, 54 m.
Ctenomys dorbignyi is now considered as belonging to the torquatusspecies group. Regarding taxonomic information and genetic structure of populations, there is some incongruence between C. dorbignyi C. perrensi , and C. roigi , because there are many cases of hybridization among populations and species. Chromosomal complementis 2n = 70 and FN = 80 to 84, and sperm is symmetric. Monotypic.
Distribution. NE Argentina, patchily in Esteros del Ibera and Pampa regions in Corrientes and Entre Rios provinces. View Figure
Descriptive notes. Head-body 190-224 mm (average 206 mm), tail 86-99 mm (average 91 mm), hindfoot (with claw) 38-7-43 mm (average 40-4 mm); weight 269-376 g (average 331 g). D’Orbigny’s Tuco-tuco is relatively large. Dorsum is brown and fairly uniform overall. Venter is light, and there is no evidence of a collar. Skull is robust and moderately long, and rostrum is slightly enlarged and expanded. Upper incisors are moderately proodont. Compared with species of Ctenomys from Chaco, interorbital width of constriction and zygomatic breadth of D’Orbigny’s Tuco-tuco are proportionately smaller, and tympanic bullae are more developed.
Habitat. Sandy patches distributed among forests.
Food and Feeding. There is no information available for this species.
Breeding. Litter size of D’Orbigny’s Tuco-tuco averages 1-3 young.
Activity patterns. There is no information available for this species.
Movements, Home range and Social organization. D’Orbigny’s Tuco-tuco is solitary, with some suggestion of semi-sociality. Densities are higher in the southern part ofits distribution. Populations are affected by cycles of annual rainfall.
Status and Conservation. Classified as Near Threatened on The IUCN Red Lust.
