Taxonomy. Ctenomys argentinus J. R. Contreras & Berry, 1982 View in CoL ,
“Establecimiento Invernizzi, Campo Araos, legua 2, 27 km norte de General San Martin, Departamento Libertador General San Martin, Provincia del Chaco, a 26°36’ de latitud sury 59°15’ de longitud oeste,” Argentina.
Based on biogeography, C. argentinus belongs to the Chacoan group, but due to results from mtDNA analysis, it has been included in the tucumanusspecies group.
Chromosomal complement is 2n = 44 chromosomes and FN = 50, 51, and 52 due to a pericentric inversion polymorphism, and sperm is symmetric. Monotypic.
Distribution. N Argentina, in Formosa, Chaco, Santiago de Estero, and Santa Fé provinces. View Figure
Descriptive notes. Total length average 260-5 mm (males) and 257-5 mm (females), tail average 84-3 mm (males) and 78 mm (females). No specific data are available for body weight. The Argentine Tuco-tuco is medium-sized. Dorsum is brown, becoming lighter toward sides where hair becomes yellowish brown; venter is pale grayish brown. Black dorsal band begins at muzzle, passes between eyes, becomes enlarged on crown, and turns narrow again, extending along dorsal surface onto tail. The Argentine Tucotuco also has a light collar. Skull is robust and allometric in growth, with heavy ridges in adult specimens. Rostrum is notably large; tympanic bullae are small and not very inflated. Upper incisors are moderately proodont. Baculum is laminar, with convex dorsal surface and enlarged proximal end.
Habitat. Dry and Humid Chaco ecoregions. The Argentine Tuco-tuco occupies sandy soils and is distributed in patches, likely a consequence of periodic floods.
