Conover's tuco-tucos are endemic to the Chaco in both Bolivia and Paraguay, occurring at an altitude of 250 m. They are found from 20 degrees S to 23 degrees S and 60 degrees to 63 degrees. This species has one of the smallest ranges of the thirty-eight currently recognized species in the genus Ctenomys. As a genus, tuco-tucos are considered to exhibit considerable ecologic plasticity. The fossil record dates back to the Pliocene in this range. Currently, it is thought that a vicariant event cannot explain present distributions.
